Structure + Systems
How a better homecomes together.
Timber frame, insulated concrete formwork, foundations and off-site systems shape how quickly, accurately and efficiently a home is built.
Explore the structural approaches behind warm, airtight and long-lasting buildings.
Structure + Systems areas
- Timber FrameEngineered timber walls, floors and roofs, often manufactured off site.
ICFInsulated formwork that combines structure and insulation in one system.
FoundationsGround solutions including insulated rafts and screw-pile systems.
Structural SystemsThe load-bearing approach that sets out spans, openings and detailing.
Off-site ConstructionFactory-built elements delivered to site for faster, more accurate assembly.
Why structure matters
Structure shapeseverything that follows.
The structural system influences insulation thickness, airtightness strategy, buildability, programme and how easily services and openings can be accommodated later.
- 01
Choose the system early
Structure affects wall thickness, floor zones and detailing, so the decision is best made alongside early design work.
- 02
Build accuracy in
Off-site manufacture can improve tolerances, which in turn makes airtightness and insulation easier to achieve.
- 03
Start at the ground
Foundations and ground conditions influence cost, insulation continuity and how the structure meets the site.
- 04
Coordinate structure and fabric
Insulation, membranes and services need designed routes through and around the structure.
What to think about
Key decisionsfor structure and systems.
Structural choices have long consequences for performance, programme and cost. These are the areas most worth understanding early.
Ground conditions
Soil, slope and access influence the foundation approach and how much groundwork a project needs.
Buildability and programme
Off-site systems can shorten time on site but need earlier decisions and clear information.
Thermal continuity
Some systems carry insulation continuously; others need careful detailing at junctions and penetrations.
Openings and spans
Large glazed openings and open-plan spaces place demands on the structure that are best resolved early.
Service routes
Wiring, pipework and ventilation ducts need planned paths that do not compromise structure or airtightness.
