London-based boutique interior design studio, Three Reasons Interior Design, have completed the design and renovation of a terrace house in Clapham Common in London. The design concept was build around the clients’ love for bold, dark wall colours which they used throughout the first floor and basement.
Both of these spaces needed furniture, lighting, and soft furnishings that would suit both family life and entertaining style-wise and practically. The clients also wanted to prioritise storage to keep the space well-organised.
To bring everything together, the team at Three Reasons Interior Design developed a cohesive design concept that included the living room as a central feature. In this space, the Graphenstone deep blue walls create a bold yet inviting backdrop, enhancing the warmth of the leather sofa, wooden accents, and the soft glow of the Pooky’s three pier gold glass chandelier.


They added bespoke, full-length curtains made by Fineline Upholstery from a fabric that balances the dark walls and white shutters, softening the room while maintaining its dramatic elegance. Statement pieces were essential to complement the room’s high ceilings. For example, the selection of two striking works from Richard Heeps’ Wicken collection adds depth and interest in the space.
These artworks not only echo the room’s rich colour palette but also add a sense of narrative, tying the scheme together beautifully.

The design concept extends throughout the home, with a unified colour palette and carefully sourced furniture, lighting, and artwork. To meet the family’s practical needs, Three Reasons Interior Design designed six bespoke joinery pieces, including a bookcase, a drinks cabinet, a cloakroom, shoe storage, a large AV unit, and a multifunctional storage cupboard. Each piece was thoughtfully crafted to blend seamlessly with the existing interiors.



The result is a home that balances style and practicality effortlessly. From the elegant living room to the custom storage solutions, every element works in harmony, creating a space that feels cohesive, comfortable, and perfect for both family living and entertaining.
