Passivhaus
We are passionate about working with clients to create modern, low-energy architecture.
We are Passivhaus experts, adopting a fabric-first approach to low-energy design on all our projects, and embedding sustainability from the very earliest concepts.
Passivhaus is the world’s most rigorous fabric first approach to low energy buildings. The core focus of the Passivhaus standard is to dramatically reduce the requirement for space heating, whilst also creating excellent indoor air quality and comfort levels.
The practice operates from a Passivhaus certified office, delivering projects across London and the South East of England. The office is monitored for energy consumption and air quality, both as a learning tool for our projects and in order to keep business overheads low.
We offer a full Passivhaus and EnerPHit design service in partnership with a Certified Passivhaus Designer.
