Every Tuesday I Promise Myself I Will Choose One Material.
One material. One process. Keep it clean. Keep it contained. Last week I was in Skellefteå, standing in front of a 20-storey building made entirely of wood, watching it report its structural health to a cloud monitoring system from sensors embedded in its walls. I told myself: come back. The building has already done the impossible. Don't follow it further.
But Tuesday always does this.
Because this week Sweden gave me not one material.
It gave me three revolutions that happen to be running simultaneously in the same country, across the same decade, feeding into the same loop — and I cannot write about one without writing about all three, because the argument only works when all three are in the same room.
Revolution One: Wood that carries the load of a skyscraper and sequesters carbon while doing it.
Revolution Two: Steel made without coal, whose only industrial byproduct is water vapour.
Revolution Three: An entire apartment — plumbing, wiring, bathroom tiles, kitchen cabinetry — built in a climate-controlled factory in northern Sweden and stacked on a city site like a precision-fitted component in the world's most consequential Lego set.
One country. Three revolutions. A single thesis.
The building as a factory product. The material as a carbon asset. The structure as a climate instrument.
This is not Sweden's lifestyle choice. This is Sweden's industrial strategy. And it is the most consequential thing happening in construction on earth right now.
THE PROBLEM SWEDEN IS SOLVING
Before the solutions, the stakes.
Sweden's domestic construction and buildings sector accounts for approximately 20% of the country's total territorial greenhouse gas emissions. When the boundary expands to include structural materials manufactured abroad and imported for Swedish projects — the concrete poured in Poland, the structural steel smelted in Germany, the cladding systems shipped from Asia — the sector's real footprint reaches approximately 33% of Sweden's total emissions. One-third of a country's entire carbon output, from the act of building.
The Swedish Climate Act has set a legally binding national target: net-zero greenhouse gas emissions by 2045, with sustained net-negative performance thereafter. The Fossil Free Sweden initiative — a state-backed industrial roadmap developed with the construction sector — translates this national law into sector-specific operational deadlines: 50% emissions reduction by 2030 against a 2015 baseline, 75% by 2040, 100% fossil-free construction materials by 2045.
These are not aspirations. They are procurement standards. The Klimatdeklaration — the mandatory climate declaration that every new Swedish building must file before receiving an occupancy certificate — is the legislative instrument that converts the targets from policy to practice. Every developer who builds in concrete must publicly declare a carbon footprint of 300 to 400 kg CO₂e per square metre. Every developer who builds in CLT declares 60 to 150 kg CO₂e per square metre. The declaration does not yet carry a fine for the higher number. But it does carry a publicly searchable record — and in a market where municipal land allocation increasingly depends on sustainability credentials, the carbon number on the declaration is becoming a planning advantage that no amount of marketing spend can manufacture.
The buildings sector decided: it needed new materials.
Sweden had the forest. It had the iron ore. It had the hydroelectric power. And it had the industrial culture to build the machines.
REVOLUTION ONE: THE WOOD THAT CARRIES SKYSCRAPERS
The question sounds wrong when you first hear it. Can you build a 20-storey high-rise out of wood?
Sweden's answer is standing in Skellefteå.
Sara Kulturhus — the Sara Cultural House — is 20 storeys tall, 75 metres high, covering approximately 28,000 square metres of floor area, housing a 205-room hotel, a library, public galleries, and multiple theatre stages. It was completed in 2021. It was built from trees grown within 60 kilometres of the construction site. And it currently holds approximately 9,095 tonnes of atmospheric carbon locked inside its walls — more carbon than the entire building emitted during its construction phases.
The material that made this possible is Cross-Laminated Timber, or CLT.
CLT is not ordinary wood. It is engineered wood at industrial scale: layers of solid structural timber dried to precise moisture content, oriented perpendicular to each other — the same cross-grain logic that gives plywood its strength — and bonded under pressure with structural adhesives. A CLT panel is not a beam or a post or a plank. It is a two-dimensional structural plate, like a concrete slab but made of laminated timber, capable of spanning horizontal loads as a floor, carrying vertical loads as a wall, or resisting lateral forces as a core.
The Physics Argument
The comparison with concrete that matters is not compressive strength alone. CLT's parallel-to-grain compressive strength runs 12 to 24 MPa — below reinforced concrete's 30 to 50 MPa. That single number is the data point the concrete industry reaches for first in any debate. It is the wrong number.
The correct comparison is strength-to-weight ratio. Reinforced concrete weighs 2,400 to 2,500 kilograms per cubic metre. CLT weighs 450 to 500 kilograms per cubic metre. At roughly one-fifth the mass, CLT's effective strength-to-weight ratio exceeds reinforced concrete's by a factor of approximately 4 to 1. A structural system that weighs four times less and performs comparably on a per-kilogram basis can carry equivalent loads through slender columns and thin wall panels — generating structural floor plates with less material, less mass, and less foundation demand than any concrete equivalent.
The foundation consequence is direct. A mass-timber building superstructure reduces gravity-induced dead loads on the foundation by 60% to 70% after accounting for live loads. In a Stockholm project built over soft marine clay — the default soil condition in much of the city's urban core — this means fewer piles, shorter piles, and reduced pile diameter across the entire foundation mat. The foundation savings from the weight reduction frequently absorb a substantial portion of the raw material premium that CLT carries over concrete at the procurement stage.
The Project Register
Sweden has been accumulating mass-timber projects at an accelerating rate, building the empirical evidence base that institutional investors and underwriters need before they will treat the material as a standard procurement choice rather than a pioneering exception.
Sara Kulturhus in Skellefteå — 20 storeys, 75 metres, completed 2021 — uses a CLT and glulam hybrid system: a glulam post-and-beam frame for the open cultural podium, prefabricated 3D CLT volumetric modules stacked between solid CLT elevator and stair cores for the hotel tower, and custom steel box trusses only where the theatre stages require clear spans that timber alone cannot achieve at economic thickness. The structural mix is honest about what wood can do natively and what it needs help with at the margin. The embodied carbon for the CLT/glulam structure: 85 to 110 kg CO₂e per square metre of gross floor area. A functionally equivalent 75-metre reinforced concrete high-rise: 360 to 410 kg CO₂e per square metre. Net reduction: 73% to 76%.
Cederhusen in Stockholm's Hagastaden district — four residential blocks of 10 to 13 storeys, up to 44 metres, completed 2022 to 2024 — is pure solid CLT above a ground-level concrete slab cast over active highway tunnels. Every load-bearing wall, floor plate, lift shaft, and stair core above the podium is CLT. The project sits over one of Stockholm's most complex foundation conditions and demonstrates that CLT's weight advantage is not merely theoretical — it was structurally decisive in enabling the building to sit over live infrastructure.
Fyrtornet in Malmö — 11 storeys, 51.5 metres, completed 2024 — is a commercial high-rise with no concrete core. Lateral stability is achieved through a central CLT inner core housing stairs and lifts, surrounded by a braced glulam post-and-beam frame with CLT floor slabs. The only concrete in the structure is a single slab at the 11th floor, added to control vibration. This is timber doing the full structural job that concrete cores typically perform, at 11 storeys of commercial loading.
Magasin X in Uppsala — 7 storeys, completed 2022 — contains zero concrete above its basement foundation. Glulam columns and beams with CLT floor panels and structural walls carry the entire building. Kajstaden in Västerås — 8.5 storeys, completed 2019 — is pure CLT from load-bearing walls to floor slabs to balconies to elevator shafts, assembled with mechanical screws that allow the entire building to be disassembled and recycled at end of life.
And then Stockholm Wood City in the Sickla district — the loop at neighbourhood scale. Twenty-five city blocks. 250,000 square metres. 2,000 homes. 7,000 workplaces. Construction commenced 2025, first phase completing 2027. The world's largest planned mass-timber urban development, built entirely without carbon-intensive structural framing, on a planning mandate that requires embodied carbon compliance with Stockholm's 2030 climate-positive target.
The Fire Physics
The fire safety question is the one every engineer asks first. Swedish building practice has a precise answer.
European spruce chars at a predictable linear rate of 0.65 millimetres per minute under standard fire conditions. Swedish engineers calculate structural panel size by oversizing for the char depth required to achieve the needed fire resistance rating: for a 90-minute rating — REI 90, required for buildings over 8 storeys — the panel is oversized by approximately 60 millimetres beyond its structural minimum. When fire occurs, the outer layer converts into charcoal. That char layer has extremely low thermal conductivity: it shields the structural core from heat and oxygen in the same motion as it forms, slowing the progression of fire into the load-bearing section at the precise rate the engineers modelled.
Above 8 storeys, Swedish mass-timber buildings add encapsulation: one or two layers of 15 mm Type X fire-rated gypsum board lining structural timber surfaces, providing 30 to 60 minutes of additional protection before any charring begins. And they add full building sprinkler coverage — a legal requirement for REI 90 to REI 120 buildings — to suppress localized fires before they can escalate to involve structural components.
The combination — sacrificial charring calculated into the panel geometry, encapsulation where required, active suppression throughout — delivers the 90-minute structural fire resistance that Boverket's Br1 building classification requires for high-rise mass-timber. Sara Kulturhus met it at 20 storeys. Fyrtornet met it at 11 with no concrete core at all.
The Regulatory Architecture
In 1994, Sweden lifted its century-old prohibition on timber frames above two storeys. The current Boverket framework (BBR) is performance-based rather than prescriptive: no legal height ceiling on timber structures, provided engineers can verify fire, acoustic, and structural load stability through measurable performance metrics. The building code asks what the building does, not what it is made of.
Städerna deliver the demand. Växjö adopted its formal Wood Construction Strategy in 2005, mandating a fixed minimum percentage of multi-family timber construction for all city-owned building projects. The city's brand position is explicit: "Växjö — The Modern Wooden City." Skellefteå built Sara Kulturhus as a policy statement and a procurement signal simultaneously. Stockholm's Wood City mandate extends municipal planning authority into material specification, tying zoning allocation and planning approval to embodied carbon commitments that concrete construction cannot meet.
REVOLUTION TWO: THE STEEL THAT PRODUCES WATER
Every tonne of conventional structural steel manufactured through the traditional blast furnace route emits approximately 1.8 to 2.0 tonnes of carbon dioxide. The chemistry is simple and brutal: iron ore (iron oxide) is fed into a blast furnace with coking coal. The carbon in the coal strips the oxygen from the iron ore. Carbon dioxide is the byproduct. The iron is the product. The emissions are structurally inseparable from the process.
For 300 years, there was no other way to make steel at industrial scale.
In August 2020, in Luleå, in northern Sweden, a pilot plant began operating a different process.
The HYBRIT Chemistry
HYBRIT — Hydrogen Breakthrough Ironmaking Technology — is a joint venture between three Swedish industrial giants: SSAB (the steelmaker), LKAB (the iron ore mining company), and Vattenfall (the electricity generator). The process replaces coking coal with green hydrogen as the chemical reducing agent.
Instead of coal stripping oxygen from iron ore, green hydrogen does it. The iron ore feeds into a direct reduction shaft furnace alongside green hydrogen generated by electrolysis of water using fossil-free Swedish hydroelectric and wind power. The hydrogen reduces the iron ore to sponge iron — Direct Reduced Iron, or DRI — and the only chemical byproduct is water vapour. The DRI is then melted in an Electric Arc Furnace powered by fossil-free electricity to produce structural steel.
What goes in: iron ore pellets. Green hydrogen. Fossil-free electricity.
What comes out: structural steel. Pure water vapour.
What does not come out: carbon dioxide.
The Geography and the Timeline
The HYBRIT infrastructure is distributed across three strategic nodes in northern Sweden, deliberately positioned to leverage the region's renewable energy surplus and iron ore deposits.
Luleå: The operational pilot plant, inaugurated in 2020. Houses the hydrogen reduction shaft furnace, electrolysis units, and a 100 cubic metre underground steel-lined rock cavern for hydrogen storage — designed to capture hydrogen during periods of low electricity prices and release it during peak demand cycles, flattening the operating cost curve.
Oxelösund: The coastal hub for final steel processing. In July 2021, SSAB Oxelösund rolled the first steel produced using HYBRIT technology at commercial scale. The blast furnaces at this site are being systematically converted to Electric Arc Furnace operation.
Gällivare: The planned location for the first industrial-scale demonstration plant, engineered to produce 1.3 million tonnes of fossil-free sponge iron annually. Construction is underway.
The commercial timeline: SSAB first delivered fossil-free steel to a commercial customer in August 2021. The initial recipient was the Volvo Group, which used the material to manufacture an autonomous electric mining dumper truck. Construction conglomerate Peab secured early allocations to use fossil-free steel in structural building columns, I-beams, and foundation piling — marking the first entry of HYBRIT steel into the built environment supply chain. Infrastructure procurement followed: Sweden's national transport authority Trafikverket has tightened lifecycle carbon requirements for bridge and infrastructure tenders, pushing contractors to specify fossil-free steel in structural applications.
SSAB's corporate target: largely fossil-free steel production by 2030. The system-level target for the HYBRIT joint venture: complete decarbonisation of the Swedish steelmaking value chain by 2045 — eliminating more than 10% of Sweden's total national CO₂ emissions in a single industrial transformation.
The Economics
Fossil-free steel currently carries a cost premium of 20% to 30% over conventional coal-produced steel at pilot production volumes. This number is the first thing the procurement analyst reaches for. It is, again, the wrong number.
Steel represents 10% to 15% of a commercial high-rise building's total construction budget. A 25% premium on steel translates to an increase of less than 2% to 3% in total project CapEx. Against the protection that number purchases — immunity from the EU's Carbon Border Adjustment Mechanism (CBAM), compliance with the Klimatdeklaration's embodied carbon disclosure, eligibility for green bond financing at lower coupon rates, and insulation from the carbon tax that the EU ETS is progressively eliminating free allowances for — the arithmetic is rapidly inverting.
The trajectory to cost convergence is driven by renewable electricity economics. The variable cost of green hydrogen production is dominated by electricity. As Sweden's hydro and wind capacity continues to expand, the cost of electrolysis falls in proportion to the electricity price. Industry projections and energy agency modelling suggest the 20% to 30% premium converges to zero by approximately 2030. After that point, fossil-free steel becomes cost-competitive with conventional steel — and the regulatory environment will have shifted sufficiently that conventional steel carries its own cost penalty in the form of EU carbon pricing.
SSAB's own language on this is direct: "Our objective is to become a completely fossil-free steel company — potentially the world's first — by 2045, with a target to be largely fossil-free by 2030, meaning no fossil CO₂ emissions from our own operations and energy use."
REVOLUTION THREE: THE APARTMENT BUILT IN A FACTORY
Italy's construction principle was: the intervention must be invisible, reversible, and smaller than the problem. Norway's was: the intervention must be permanent, unavoidable, and larger than the impossibility. Sweden's is: the intervention must be precise, weatherproof, and manufactured before it arrives.
3D volumetric modular construction is the industrial logic of the Swedish model at its most concentrated. A complete apartment — structural frame, insulation, windows, plumbing manifolds, electrical wiring, bathroom tiles, kitchen cabinetry, floor finishes — is assembled indoors in a climate-controlled manufacturing facility. The finished module is sealed, loaded onto a flatbed truck, driven to the construction site, lifted by crane, and connected to adjacent modules with structural bolts and service hookups. The building is assembled rather than built.
The Speed Arithmetic
The financial argument for volumetric modularity is not environmental. It is the time value of money applied to construction finance.
A conventional concrete mid-rise follows a linear timeline: foundation (4 to 6 weeks), shell and core casting (16 to 24 weeks), fit-out (16 to 24 weeks). Total: 9 to 14 months, during which the developer is servicing a construction loan without generating revenue.
A Swedish volumetric mid-rise operates on a parallel timeline: while ground teams excavate and pour the foundation (4 to 6 weeks), the factory simultaneously builds and finishes the modules. When the foundation cures, the modules arrive sequentially and are stacked. Structural shell completion: 2 to 4 weeks for a mid-rise block. Final service connections: 4 to 6 weeks. Total on-site programme: 3 to 4 months.
The 8.5-storey Kajstaden building in Västerås had its entire mass-timber structural shell assembled in 3 to 4 weeks of on-site work. The equivalent in cast-in-situ concrete would require 12 to 14 weeks for the structural phase alone.
Sara Kulturhus erected one complete storey every two working days during the structural assembly phase. Because CLT is a dry construction method — no wet concrete curing, no drying time — fit-out crews moved onto the lower floors immediately after the upper floors were assembled. The building effectively built and fit-out simultaneously rather than sequentially.
The financing consequence at a project level: a developer who achieves a 50% reduction in total construction programme pays roughly 50% less construction loan interest for the duration of the shorter programme, compounded by the earlier start of rental income generation. In a Swedish market where construction loan rates have been running above 5% since the 2022 rate cycle, this is not a marginal benefit. It is a first-order financial variable.
The Labour and Waste Arithmetic
A conventional in-situ concrete mid-rise requires a daily on-site workforce of 40 to 60 people. A Swedish volumetric mass-timber assembly site requires 6 to 10 workers — a crane operator, spotters for truck deliveries, and structural connection specialists. The 80% reduction in on-site headcount is not a statistic about efficiency. It is a transformation of what a construction site is: from a manufacturing operation employing dozens of specialists working in unpredictable outdoor conditions, to a logistics hub where precision components arrive, are checked, are lifted, and are bolted.
Material waste falls proportionally. Conventional construction sites factor a 10% to 15% material waste buffer into procurement budgets. CNC-cut CLT modules produced inside a factory facility generate less than 1% to 2% waste. Remaining wood shavings are compressed into biomass pellets for regional district heating networks. Zero landfill. Zero weather-damaged material. Zero over-ordered concrete poured to waste.
The Swedish Industrial Players
The volumetric manufacturing ecosystem that makes this possible is not a collection of startups. It is an established industrial sector with anchor players, decade-long track records, and scalable capacity.
Lindbäcks Bygg, headquartered in Piteå, operates one of Europe's most advanced automated timber volumetric factories. The production line constructs fully enclosed 3D rooms — complete with internal insulation, plumbing manifolds, electrical wiring, and bathroom tiling — before shipping them to site. Their system stacks modular units to 6 to 8 storeys without requiring an external concrete or steel skeleton.
BoKlok, the joint venture between Skanska and IKEA, applies the mass-market logic of IKEA's supply chain to the residential housing sector. Standardised structural dimensions fixed to repeatable templates. Material yields optimised by the same lean manufacturing principles that make an IKEA flat-pack kitchen globally affordable. Multi-family clusters assembled in a fraction of the time a conventional developer would require.
Derome controls its supply chain from forest to finished home, operating regional sawmills, roof truss facilities, and modular assembly plants. Moelven Byggmodul specialises in institutional, healthcare, and educational facilities alongside permanent residential complexes, using tongue-and-groove connections that allow modules to be disassembled and relocated — turning buildings into redeployable infrastructure rather than permanent fixed assets.
The Convergence: CLT Modules and HYBRIT Steel
The most advanced application of Sweden's three revolutions is not any individual technology. It is their convergence in a single structural product.
As modular timber buildings grow taller, the connections between stacked CLT modules experience compounding structural stress. The response is hybrid engineering: fossil-free steel corner castings and structural splice plates, manufactured from HYBRIT-derived steel, bolted into CLT modules at the factory before delivery, enabling the structural joints to achieve near-zero embodied carbon while handling the concentrated loads that pure timber connections cannot manage at height.
A CLT module fitted with HYBRIT steel corner brackets carries its carbon in the wood — approximately 15 to 25 tonnes of biogenic CO₂ stored inside the structural frame of a single apartment module — while its structural connections carry zero Scope 3 smelting emissions. The wall of the building is a net carbon negative. The joint of the building is a net carbon zero. The floor plate is a factory-quality, dimensionally precise, acoustically tested assembly that performed its last QA check before it left northern Sweden.
That is the whole system.
THE INDIA MIRROR: THE FACTORY THAT INDIA NEEDS TO BUILD
India pours 42.8 million tonnes of cement every month. That number is not going down. India's urbanisation trajectory will not permit it. The 40% of 1.45 billion people who will live in cities by 2030 require floor area that has to be produced by some process, and concrete is currently the only process India's construction industry knows how to deliver at the required speed and scale.
But Sweden is demonstrating something directly transferable to specific segments of India's construction challenge.
The Himalayan and hill-state corridor — Uttarakhand, Himachal Pradesh, parts of Jammu and Kashmir — is a zone where concrete's structural logic is actively hostile. Heavy foundations on fragile seismic terrain. Wet concrete in extreme cold. Construction seasons compressed by weather. And the precise zone where India's infrastructure expansion — the Char Dham highway, the Zoji La tunnel, the new connectivity corridors — is creating the highest density of new construction activity on geographically unforgiving ground.
CLT and engineered bamboo volumetric modules, prefabricated in factories sited in the foothills and transported to assembly sites, would reduce both the seismic risk profile and the carbon profile of construction in this terrain simultaneously. The weight advantage matters: lighter structures on fragile slopes generate lower foundation loads on soils that concrete structures would require expensive and environmentally disruptive deep piling to stabilise.
The HYBRIT analogy for India is HURL — Hindustan Urvarak and Rasayan Limited — and the green hydrogen programmes currently being piloted by SAIL and Tata Steel's decarbonisation roadmaps. India's steel sector is the second-largest in the world and among the most coal-intensive. The technology pathway Sweden has opened is the same pathway India's steel sector will eventually have to walk. The question is whether India invests in the process when renewable electricity is cheapest, or waits until the carbon pricing environment makes the delay expensive.
The factory-built apartment module is India's most immediate practical opportunity. The worker housing corridors along India's freight and industrial corridors — the DFC housing zones, the DMIC logistics hubs, the new smart city residential allocations — are exactly the segments where volumetric modular construction's speed advantage is most financially decisive: high construction demand, compressed timelines, cost-sensitive buyers, and limited tolerance for the weather delays and labour uncertainty that plague conventional on-site construction in northern India's summer and monsoon seasons.
A prefabrication factory producing 3D residential modules in Rajasthan or Haryana, assembling affordable mid-rise housing for corridor workers in a schedule that fits an 18-month developer finance window rather than a 36-month concrete cycle, would not require Sweden's CLT supply chain or HYBRIT steel economics. It would require India's own engineered bamboo panels, its own Light-Gauge Steel Framing industry, and the institutional decision that a building is not a construction project. It is a manufacturing product.
Sweden made that decision first.
The technology is available. The model is proven. The forest loop takes decades to build. The factory can begin next fiscal year.
THE PRINCIPLE: THE BUILDING AS A FACTORY PRODUCT
Italy's Tuesday principle was: the intervention must be invisible.
Norway's Tuesday principle was: the intervention must be inescapable.
Sweden's Tuesday principle is: the intervention must be manufactured before it arrives.
The wood that carries a 20-storey hotel was growing in a managed forest sixty kilometres away. The steel that connects the modules was made without coal in a pilot plant that opened five years ago and has already delivered to commercial clients on three continents. The apartment that stacks on top of it was assembled by six workers in a factory in northern Sweden while the foundation was still curing.
The building sector emits 20% of Sweden's territorial carbon. The three revolutions documented in this article are its response — not as a lifestyle gesture, not as a policy slogan, but as an industrial transformation designed to survive the carbon pricing environment of 2030 and outlast the construction economics of 2045.
Sweden did not wait for the carbon tax to arrive before beginning the decarbonisation.
It built the materials first.

This was my Technology Tuesday rabbit hole.
I told myself: one material. One process. Something you can hold in your hand.
By Tuesday morning I was inside a factory in Piteå watching a crane lift a complete apartment — bathroom tiled, kitchen fitted, wiring terminated — off an assembly line and onto a flatbed truck. Somewhere else in Sweden, in a shaft furnace in Luleå, hydrogen was reducing iron ore to sponge iron and producing water vapour as its only waste stream. And in Sickla, twenty-five city blocks were going up in mass timber because a municipal planning office decided that Stockholm should be climate-positive by 2030 and chose the material that made the arithmetic work.
Three revolutions. One country. The same decade.
The forest grew the building. The hydrogen cleaned the steel. The factory built the apartment.
And somewhere in India, the same option is still available.
That is where Tuesday always ends up: not with the technology, but with the question of when we decide to use it.
Beautifully.

If Italy's Invisible Armour showed us a building that has already written its own instructions in stone across eight centuries — asking only that we listen carefully enough to add one more line without erasing anything that came before —
And if Norway's Subsea Frontiers showed us a country that looked at a kilometre-deep fjord and heard not instructions to preserve but an invitation to build —
Then Sweden's Fossil-Free Foundations show us something between both: a country that looked at 28 million hectares of managed forest and heard a manufacturing brief. Not a resource to extract. A material to engineer. Not a landscape to preserve. A carbon asset to deploy.
The tree grew for seventy years. The hydrogen shaft reduced it to steel in hours. The factory assembled it into a home in days. The crane stacked it onto the city in minutes.
That is the loop. Sweden closed it. The rest of the world is still drawing the diagram.
