This project reimagines a classic London residence through the addition of a contemporary single-storey rear and side extension. The transformation introduces a bright, free-flowing kitchen and living area at ground level—designed to maximise natural light and establish a seamless connection between the interior and garden. The result is a refined, open-plan environment that enhances both day-to-day living and the property’s long-term appeal.
MMHM Structures Ltd provided the complete structural design package, working hand-in-hand with the lead architect to create a solution that blended elegance with practicality. Every element of the design was carefully considered to ensure that the new structure integrated seamlessly with the existing fabric of the home, maintaining architectural integrity while delivering strength, efficiency, and cost-effectiveness.
The structure was meticulously engineered to achieve uninterrupted internal spaces—aligning with the architect’s vision for openness and light. New structural columns were discreetly placed and concealed within key internal walls, preserving visual clarity and a sense of spaciousness throughout. This approach allowed the architecture to lead the experience, with structure performing quietly in the background.
Key structural features include:
Superstructure: Concealed steel sections form the backbone of the upper structure, supporting extended masonry walls, new and existing roof elements, and the retained first-floor structure. This ensured structural continuity, robustness, and a seamless architectural finish.
From the earliest stages, MMHM Structures adopted a collaborative, detail-driven approach—balancing technical expertise with creative design thinking.
Working closely with the architect, the team developed a structural strategy that supported buildability and cost control without compromising the project’s architectural ambition.
Each component—from foundations to framing—was refined to deliver performance, functionality, and enduring value.
