A wrap-around extension that extends both the side and rear of a property, creating an L-shaped addition that wraps around the existing structure. This project maximized the use of available space, providing a spacious and open-plan kitchen area with space for informal dining, a utility room, and a downstairs toilet. Features included top-notch glazing from Maxlight, underfloor heating, an oak parquet floor, and a custom-designed kitchen from Naked Kitchens.
A dormer roof extension that adds space to a home by extending the existing roof structure. This project involved building vertical walls to create a cube structure with a flat or gently sloping roof, opening up the roof space to form an additional room. The extension was completed within 12 weeks and included modifying the existing roof structure, integrating the dormer, and replacing existing ceilings below for insulation. The client chose like-for-like external tiles and PVC windows for thermal efficiency.
A standalone structure situated in the garden, providing a dedicated area separate from the main living space, ideal for working from home or hobbies. This build maximized garden space and offered a peaceful, private setting. Features included triple-glazed trifold doors from Maxlight, electric underfloor heating, an engineered oak floor, and bespoke built-in furniture.
A mansard loft conversion that adds significant space and value to a property, particularly end-terrace properties with a parapet. This project involved removing an old flat roof, repairing the parapet wall, and constructing the mansard structure. It was completed in 12 weeks and featured natural slate tiles, specialist aluminum windows, and water-piped underfloor heating.
