EnerPHit Plus Victorian Townhouse

These two semi-detached homes are Europe's first Passivhaus Plus retrofits. This exemplar project has achieved a 95% reduction in space heating demand with zero energy bills. The project goes beyond Passivhaus by minimising embodied carbon and using only natural building materials to achieve a petrochemical-free, breathable building fabric. Incorporating 8 world first technologies/methodologies, this was truly a laboratory for domestic retrofit.

Awarded the International Passive House Association Living Comfort Prize 2021, ASBP People's Prize 2022, and Shortlisted for the AJ Retrofit Awards 2019
