Gwilym Still


Director, Passivhaus Leader, Partner

I enjoy helping to deliver robust, low-energy designs that work and are sensitive to the building’s architecture, whether adapting an existing building, or developing a new one.

Essentially, it’s about appropriate design to meet the brief. I can deliver Passivhaus graduate accommodation for a Cambridge College, low-energy office buildings for owner-occupiers, and very simple, grassroots designs as part of Max Fordham’s Developing Countries Group.

I am a certified Passivhaus Consultant, lead Max Fordham’s Passivhaus service, and have more than 14 years of experience in construction across a range of project sectors, scales and stages. My project work includes new build, refurbishment and extension projects across a wide range of market sectors.

My Passivhaus experience includes acting as both Passivhaus Consultant and MEP designer on two new student accommodation projects encompassing 6 buildings, Cranmer Road and Croft Gardens, for King’s College Cambridge. I am also carrying out the Passivhaus consultant role on residential work for Agar Grove Phase 1C, a major 493-home Passivhaus development for the London Borough of Camden, and in the education sector on St Mary’s School Creative Arts Hub, a 4-storey education building for music, food technology, art and textiles.

I enjoy working on projects through all stages, right through from concept design to aftercare. This continuity enables me to get an understanding of performance in-use and feed this back into the design phase of future projects.

Throughout the design process I help optimise the building design using building physics and other modelling software, and then play an active role in site delivery and commissioning. With experience ranging from heating and water systems through to lighting and controls, I’m well-versed in delivering low-energy environmental design.
