In London’s Hackney Downs, Material Works Architecture has transformed a once-constrained Victorian terrace into a contemporary, low-energy home centred on spatial generosity and daylight. At Hackney Bay House, the most significant intervention is the reshaping of the lower ground floor: by lowering the slab, the design introduces increased ceiling heights that shift the atmosphere from enclosed to expansive. This enlarged volume rises into a striking double-height space at the rear, anchored by a two-storey bay window that draws natural light deep into the plan while framing the garden as an extension of everyday living.

A mezzanine study hovers above this new family hub, offering a calm retreat that maintains visual connection with the kitchen and garden. This layered vertical organisation supports modern working patterns while preserving cohesion within the home.

Landscape as a continuation of the interior

The garden renovation reinforces the project’s principle of seamless transitions. A series of stepped terraces and integrated planters create subtle topographic shifts that mediate between the lowered internal floor level and the natural ground line. These terraces form outdoor rooms for play, gardening, and dining, encouraging year-round engagement with nature.

At the garden’s end, a compact timber-clad studio offers a dedicated workspace for music and creative work. Clad in timber shingles and wrapped internally and externally in cork, the studio is acoustically insulated while maintaining a warm, natural tactility.

Building lightly: low-carbon materials and methods

The project adopts a fabric-first sustainability strategy, prioritising low embodied carbon materials and careful envelope upgrades. The reconstructed rear elevation employs timber framing and high-performance wood-fibre insulation, significantly reducing thermal bridging. Reclaimed bricks complete the exterior, ensuring material continuity with the Victorian façade while avoiding the carbon impact of new masonry.

Internally, natural lime plaster regulates humidity and maintains breathable wall construction, while tinted cement floors provide durable, high thermal mass surfaces that work in tandem with passive solar gains. Bespoke joinery and exposed structural components are crafted from English oak, selected for longevity, local sourcing, and low environmental impact.

Performance upgrades for the long term

Energy efficiency is strengthened through a combination of passive measures and discreet technologies. New high-performance windows reduce heat loss without compromising heritage proportions, and the building fabric has been upgraded throughout with continuous insulation that exceeds current regulatory standards.

A compact air source heat pump provides efficient space heating and hot water, allowing the home to operate on electricity alone and significantly reducing operational carbon. Together, these measures future-proof the Victorian structure while maintaining the sensitivity and character essential to its identity.
