Hampsthwaite | SIP Self-Build Dwelling.

A structurally efficient SIPs dwelling designed to accommodate large open-plan spans and vaulted spaces within a sensitive historic setting. The primary structure is formed from the SIPs envelope, supplemented with discreet steelwork and architectural glulam where longer spans and load redistribution were required. Steel members were rationalised and concealed within floor and wall zones to maintain clean internal geometry, while glulam elements were left exposed where structurally and architecturally appropriate. The SIPs system provided inherent racking resistance, predictable load paths, and high thermal performance (U-values down to 0.15) without secondary insulation layers, while also reducing overall wall and roof build-ups by approximately 175 mm compared to traditional construction. This allowed maximisation of usable internal volume within the planning envelope. The complete superstructure was erected in four weeks, giving a controlled programme, reduced site risk, and early weather-tightness for follow-on trades.
