Today is World Environment Day, and for us, sustainability isn’t a date on the calendar, it’s built into how we work every day, across every project.

This year’s theme, land restoration, desertification, and drought resilience, is a reminder that the built environment has a direct role to play in how we protect and restore the natural world. From the materials we specify to the energy strategies we advise on, our work shapes how buildings perform for decades to come.

We are proud to hold ISO 14001 accreditation, which we have maintained since 2006. Our commitment to reducing our Scope 1, 2 and 3 emissions, achieving carbon neutrality across our offices by 2035, and advising clients to do the same runs through everything we do.

Here are just a few recent examples from our project work:

Melfield Gardens, Catford – A Passivhaus scheme delivering 30 affordable homes for residents aged 55 and over, with direct electric heating and waste-water heat recovery, reducing fuel poverty while eliminating gas from the building entirely.

Fen Road, Ditton Fields & Borrowdale, Cambridge – Cambridge City Council’s first Passivhaus-certified council homes, featuring MVHR systems, air source heat pumps and reduced energy bills for tenants. Sustainability was designed from the start, not added as a bolt-on.

Waltham Forest Town Hall – A residential development with air source heat pumps, PV panels, MVHR, a SuDS wetland, over 200 new trees, and a car-free layout with more than 800 secure cycle spaces, demonstrating what genuinely low-carbon urban housing can look like.

Moulsecoomb Regeneration  – 220 social rented homes with ground source heat pumps, PV panels, rain gardens and SuDS, built alongside community facilities including a BREEAM Excellent medical centre.

Hart Road – A net zero carbon development using a closed-panel timber frame, air source heat pumps and PV panels, delivered for Legal & General Affordable Homes, one of their first schemes to this standard.

The earlier sustainability is built into a project, the greater the impact. That’s why these conversations start at feasibility, not at planning, not at tender.
