Continuing this approach at ground floor.

A new garden-facing extension opens up the plan into a more continuous, light-filled space—while the existing house is retained and read as a distinct layer.

The extension is conceived as a lightweight timber structure, with expressed loadbearing elements.

Planning permission secured in Greenwich.

Planning permission granted for our next project in Greenwich.

Working within an Eric Lyons-designed Span estate in Blackheath, the proposal carefully reworks an existing house: opening up the plan and strengthening its relationship to the garden, in keeping with the original ethos of light, space and landscape.

Progress in the rain.

Works are well underway in our timber frame extension on the hill in Brightling Road.

Excited to announce our project in Hackney has been granted planning approval.

We’re helping our clients transform a long-term empty house into their ideal home for their young and growing family, contributing to the rich and diverse fabric of the neighbourhood.

Our design introduces a series of extensions at ground, first, and loft level with internal reconfigurations and structural interventions. Drawing from Belgian Modernism and influences from the New Zealand Christchurch style, the scheme combines London stock brick, quarry tiles, and red-lacquered timber, with red oxide metal detailing to bring new life to a once-vacant property while respecting its Victorian character.

An Enduring Continuity

Dulwich Wood integrates seamlessly into the existing terrace. Its brickwork, proportions and rhythm extend the established streetscape, carrying forward the architectural language of the estate with precision and care.

Continuing the Legacy.

This new home in Dulwich carries forward the architectural language of the neighbouring 1960s Dulwich Estate terraces.
Referencing the celebrated Halen Estate, it picks up on familiar forms like buff brick coursing, timber porticos and projecting bays, while refining them with quiet clarity.

The design fits naturally within its context and moves the conversation forward through a series of low-carbon changes, such as CLT framing structure and passive heating systems to enhance performance and sustainability.

A Low-Carbon Re-imagining of Mid-Century Modern in Dulwich Wood

We’ve designed a new home in Dulwich as a continuation of the language of the area’s celebrated 1960s terraces. Inspired by the influential Halen Estate near Bern, a benchmark of Mid-Century European modernism.

Respecting the scale, rhythm, and materiality of its neighbours, our design reinterprets key elements of alternating buff brick coursing, projecting bays, timber porticos, with quiet precision and care.

Behind its familiar façade we’ve shifted the structural strategy using a full Cross Laminated Timber (CLT) structure, dramatically reducing embodied carbon, improving thermal performance, and creating warm, highly performing spaces.

Our goal was to create a contextual architecture, to not just fit in but to lead on sustainability.

A quiet reinvention, rooted in place, guided by history, and built for the future.

Antrobus Road, Chiswick
Concept render for our recently completed townhouse project.

When the Clients first approached HA-EY, they shared a familiar dilemma: they loved their street, but needed more space to grow—without compromising the garden they cherished.

Our brief was clear—maximise internal living space while preserving and enhancing outdoor amenity. Detailed analysis of daylight and sunlight was undertaken to carefully determine the extension’s limits, ensuring no adverse impacts on neighbouring homes or gardens.

Through a contemporary reinterpretation of the local brick vernacular, we introduced a series of stepped terraces topped with GROW-rated native wildflower roofs—expanding the footprint by over 50%, greatly increased biodiversity and allowing our Client’s to stay in the community that they loved.

We Made This:

Thank you to everyone who joined us at last night’s end-of-year show. It was a privilege to share our latest timber bridge model, developed and built in collaboration with our students, and to see such a strong body of work across the school.

Next, the model will travel to the River Derwent for display and conversations with the local community. This forms part of our ongoing work on the proposed Derwent Valley Cycleway —a route designed to connect people with the landscape, its industrial heritage, and vital ecological systems.

Our recent split beam girder bridge prototypes explore new potentials in timber construction through careful design, testing, and making. By looking to historic typologies and applying modern engineering insight, our research aims to advance sustainable, locally built timber infrastructure.
