AFL Build

We construct outstanding architectural homes and workplaces that are both sustainable and beautiful.

Our residential projects include new homes, refurbishments of heritage properties and house extensions at all scales. We also offer a complete turn-key solution, including architectural design and structural engineering.

Our team of specialist craftspeople work toward the most stringent Passivhaus eco-design principles to deliver low-energy properties that are healthy, warm and comfortable throughout the year.


We have a unique contemporary approach to construction, enabled by a suite of digital management tools. These allow for seamless site communication during construction and improved client and aftercare services.

Our site teams are led by experienced architects and project managers, who form the main point of contact for our clients throughout. They work with each site manager to ensure quality whilst monitoring progress and budget.

Whilst we are able to offer a complete architectural design, structural engineering, interior design and build service, we also work with other architects, engineers, interior designers and clients to provide construction services only.


We specialise in creating bespoke architectural homes and workplaces in London and the south east. Our work includes both new build properties and sensitive additions to heritage properties, including listed properties and those in conservation areas.

We take pride in our ability to navigate the complexities of constrained London sites with neighbours in close proximity and we work closely with local residents to minimise noise and disruption.

We invest in the skill and expertise of our team, encouraging development training and mentorship through a programme of skill-based courses. Our team includes a Passivhaus-certified tradesperson and CSCS-qualified site managers.


Environmental impact is a key consideration in our work. We take a fabric-first approach to sustainability based on the Passivhaus principles of airtightness, high-performance insulation, triple glazing and MVHR.

We build comfortable, fossil fuel free homes, with heating and hot water provided by air-source heat pumps, ultimately aiming for net zero energy in use. This accords with UK’s requirement to reach net zero across all sectors by 2050. The homes that we retrofit now will not be refurbished again before this date, so each project is critical.

In addition to the performance of our buildings in use, we carefully consider embodied energy. We use materials and processes with less embodied carbon and repurpose materials on-site where possible to reduce waste. For all other waste disposal, we use partners who are committed to diverting waste from landfill with transfer stations that specialise in re-use and re-cycling.
