We have a passion for sustainable, low-energy architecture that connects with its natural environment.

Evergreen Architects are Passive House Designers.

Evergreen Architects are based in Anglesey and the Wirral, with projects across Wales and the North of England. Many of our projects are in rural Areas of Outstanding Natural Beauty.


Together with our clients we have delivered over 100 projects, including: private new build residential dwellings, contemporary extensions, listed building works, swimming pools and boutique commercial buildings.

Passive House is a rigorous, practical methodology to achieve a 75% reduction in space heating requirements, compared to standard practice for UK new build. It creates more comfortable, environmentally responsible and healthier buildings.

We use accurate design modelling with the Passive House Planning Package (PHPP) and our 3D BIM software.
