Case Study: Design & Build — Extension & Renovation
Stunning transformation and upgrade of a substantial family home.
The Overview.
Richard and Caroline already knew who to call. Years earlier, a loft conversion on their previous home had established a trusted relationship, recommended by neighbours who had seen the quality of work first-hand. When they moved to a larger property in Radlett, the decision was straightforward.
Their ambition was significant: a full three-floor transformation including major extensions to the ground and first floors, an expanded loft conversion, and a complete roof rebuild. In an area where planning permission is rarely simple, securing consent required careful design and persistence, setting the foundation for a seamless and cohesive home.

The scale of the project introduced a key risk: that a large, multi-level extension could feel disjointed rather than cohesive. This was addressed through careful architectural planning and detailed execution, ensuring the old and new elements blended seamlessly.
The ground floor was significantly extended to create open-plan living and kitchen areas, finished with tiled flooring and underfloor heating throughout. The first floor added bedrooms and bathrooms aligned with the design quality below, while the expanded loft conversion was fully integrated into the overall structure.
A bespoke lighting scheme was implemented across all spaces, alongside a high-spec kitchen featuring a Quooker boiling water tap. Additional features such as a bespoke sauna elevated the home further, demonstrating a consistent level of craftsmanship throughout.
Externally and structurally, the extensions were matched precisely to the original property, ensuring a unified appearance with no visible transitions between old and new. The result is a home that feels intentionally designed as a whole, rather than assembled in parts.
