House Extension & Renovation

Llanberis, Gwynedd, 2018

​

The client wanted a two storey extension designed to near passive house standards. Part of this strategy involves providing high levels of insulation and air tightness to reduce heat loss. We used traditional timber frame construction and timber cladding, both locally sourced and using local manufacturers. Additional insulation has been added to the internal walls of the existing house to improve its thermal performance.​
