Sustainability Report

Embodied carbon and material strategy

• Internally, the house unfolds through a sequence of vertical and horizontal layers, shaped by a series of carefully judged architectural interventions that work with the existing structure rather than replacing it.
• An existing central rooflight, an uncommon feature in a London terrace, became the starting point for the design. Rather than infilling above and removing this feature, ConForm extended the void upwards, retaining and amplifying an existing spatial condition within the building.
• Materially, the house is unified through a restrained, tactile palette. Oak, whitewashed mortar, chalk-white brick, concrete downstand beams, perforated steel, and ceppo di gre are used consistently throughout, allowing cohesion while introducing subtle variation between spaces. Raw brickwork and concrete are set against more refined stone and timber finishes.
• Custom joinery is integrated across all levels, with timber-framed windows used throughout. The staircase and balustrade are expressed as solid, sharply defined elements, forming part of the architectural structure of the house.

Operational considerations: daylight and environmental connection

• An existing central rooflight became the starting point for the design, establishing daylight as a key spatial driver within the split-level plan.
• Connections between levels are formed through open stair treads, perforated steel floorplates, and open voids, filtering light, air, and sound throughout the house and maintaining visual connections between floors.
• Brickwork finished with a whitewashed slurry lines the central void, reflecting and softening incoming daylight as it moves through the interior.
• At the lowest level, the living space opens directly onto an outdoor terrace via a pivoting glazed door. External finishes closely mirror those inside, establishing continuity between interior and exterior as daylight moves across the concrete-framed rear extension, timber fencing, and stone flooring.
• A wholesale upgrade of the rear of the house has improved insulation and breathability.
