When searching for a trusted building contractor in Chelsea, homeowners and design professionals require a partner who understands the delicate balance between preserving historic architectural charm and integrating cutting edge modern performance.
MATTR Projects is a premier London based residential main contractor specialising in the high end refurbishment, extension, and transformation of period homes across SW3 and SW10. We work closely with private clients, visionary architects, and interior designers to deliver carefully considered, meticulously managed construction projects designed for contemporary family living.
Chelsea boasts some of London’s most prestigious residential architecture, from the elegant Georgian townhouses of Chelsea Square to the iconic red-brick mansion blocks near Sloane Square. However, updating these properties comes with unique challenges.
As an experienced building contractor in Chelsea, we are highly adept at navigating the stringent planning and conservation constraints enforced by the Royal Borough of Kensington and Chelsea (RBKC). We handle the logistical complexities of working in prime Central London, including:
Our approach is rooted in "fabric first" engineering, combining traditional, breathable craftsmanship with modern building physics so your home looks timeless but performs like a newly built property.
1. Luxury Refurbishments & Period Restorations
From reinstating original ornate cornicing to breathing new life into tired Victorian masonry, our restoration work is unparalleled. We pride ourselves on the invisible integration of modern mechanical and electrical (M&E) systems, such as underfloor heating, smart home automation and acoustic dampening, hidden beautifully behind period detailing.
2. Bespoke House & Loft Extensions
Expanding a property in a dense urban environment requires architectural precision. Whether it is a light filled rear glass extension or a highly technical structural reconfiguration, we execute complex spatial designs flawlessly. See how we approach complex spatial upgrades in our bespoke loft and house extension in Kentish Town.
3. Deep Energy Retrofits
Many period homes in Chelsea suffer from poor thermal efficiency. We specialise in deep retrofits that drastically cut energy usage without trapping moisture or ruining the home's character. By utilising breathable natural insulations, high performance slimline glazing, and MVHR (Mechanical Ventilation with Heat Recovery), we future proof legacy properties.

A luxury finish is only half the picture; how a project is run is just as important. Our commercial background allows us to bring Tier 1 contractor rigour to the residential sector. From transparent procurement and detailed programming to honest, proactive communication, we ensure our clients and their design teams have complete peace of mind from demolition to handover.
