Decades of delivering sustainable buildings
Our team has 70+ years of collective experience delivering sustainable construction projects. We have seen what works on site as well as on paper, so the advice we give is practical, buildable and grounded in real results.
That experience shapes how we work with clients, contractors and design teams, from the first conversation to the finished building.

Sustainable design that starts at the drawing board
We design highly sustainable buildings, and we build Passivhaus standards into the design from the outset. Orientation, form, glazing and the building envelope are settled together, so performance is part of the architecture and not a fix added later.
Because we design as well as advise, we understand the pressures on a design team and write our guidance to suit.
The right qualifications in one team
Our team brings together the accreditation and professional standing that high-performance projects call for.

We know housing, at every scale
We have delivered multiple schemes to the Passivhaus standard, totalling 91 Passivhaus certified dwellings, from one-off homes to affordable housing estates and residential apartment buildings.
That range means we understand the different pressures on a self-builder, a housing provider and a developer, and what each needs to see to get a scheme built.
Retrofit, including heritage and listed buildings
Our team has extensive experience of delivering retrofit projects across a range of sectors, including residential and commercial, often involving heritage buildings, including Listed Buildings.
Upgrading an existing building takes careful judgement. We balance better comfort and lower energy use with the character and fabric of the original, working towards the EnerPHit standard where it is feasible.
Commercial buildings as well as homes
Our team has experience applying Passivhaus standards and technology to commercial developments, and delivering highly sustainable projects.
That experience spans the industrial, heritage, office, retail and education sectors.
How we think about buildings
A few principles guide every project, whatever the size.
Fabric first
A well-insulated, airtight building envelope does most of the work. We get it right before adding technology.
Measured, not assumed
Performance is modelled in the design and checked against real results, so claims rest on evidence.
Plain-English advice
Passivhaus can sound technical. We explain it clearly, so you can make informed decisions at every stage.
Who we work with
Our clients range from individuals building one home to teams delivering hundreds.
Homeowners and self-builders
Housing associations and affordable housing providers
Developers
