Kensington
A garage was transformed into a high-end luxury two-bed flat through a full dig-out and damp-proofing, maximising space and changing the property's purpose.

Hampstead
A basement was converted to include a swimming pool and spa, with a contemporary and sleek feel, and a heat recovery system installed to distribute heat around the house.

Kings Cross
The existing basement was enlarged under the garden, leading to a subtle extension that fills the house with sunlight, creating a playroom for children and connecting the ground floor to the garden.

Kings Cross
Clients wanted a playroom and to connect their ground floor to the garden. The solution involved extending the existing basement beneath the garden and creating a modest rear extension that streams light into the house, despite conservation area and listed building status.

Bethnal Green
An old and neglected house was given a fresh look with a zinc-clad rear extension, flush frameless doors, a large frameless skylight, underfloor heating, and a minimalist modern staircase. Landscaping and ebony decking completed the garden.

Richmond
Multiple rooflights were introduced into a large detached house's expansive roof area to maximise light and head height, resulting in an elegant space that feels both cosy and generous.

Chiswick
A simple but perfectly crafted dormer loft conversion in West London, demonstrating how a modest house can expand its space by adding a bedroom and bathroom in the loft.

Holland Park
A full refurbishment of a terraced house.

Tufnell Park
