The Hemp House Extension
The Hemp House Extension
Designed by Nimtim Architects, the "Hemp House" is a thoughtful London extension that prioritizes low-carbon living without sacrificing modern aesthetics. Featured in Dezeen, the project serves as a versatile new living space for a growing family, pushing the boundaries of sustainable residential design.
Innovation Through Materiality
Innovation Through Materiality
Built in collaboration with UK Hempcrete, the extension serves as a primary case study for the synergy between timber framing and hempcrete infill. This combination replaces traditional high-carbon materials with bio-based alternatives that sequester CO2 during their growth.
Why Hempcrete?
Why Hempcrete?
Hempcrete isn't just an eco-friendly trend; it is a high-performance material that offers a "double win" for homeowners:
Exceptional Thermal Performance: By combining high thermal insulation with significant thermal mass, hempcrete maintains stable indoor temperatures—staying warm in winter and cool in summer.
Energy Efficiency: The material can reduce heating energy requirements by up to 70%.
Carbon Neutrality: It achieves low-carbon construction while enabling a path to zero-carbon heating.
Passive Solar Synergy: Its efficiency is so high that it is ideal for passive solar designs, often eliminating the need for traditional heating systems entirely.
