Single & Two Storey Extensions Richmond
Adding space to your Richmond property doesn’t mean compromising on character. We design extensions that enhance your home’s architecture whilst creating the room you need – whether that’s a bright kitchen extension overlooking your garden or a two storey addition providing extra bedrooms and bathrooms.
Our extensions blend seamlessly with Richmond’s diverse property styles, from Victorian terraces near Richmond Green to Edwardian semis in North Sheen and post-war houses around Kew Road.
Complete Home Renovations & Refurbishments
Thinking of renovating your Richmond home? We specialise in full-scale house renovations that transform tired properties into stunning modern homes. From period property refurbishments that respect original features to contemporary makeovers, we project manage everything – structural work, electrics, plumbing, plastering, decorating and landscaping.
Recent refurbishment projects span Richmond Hill, East Sheen, Mortlake, Barnes, Kew and Ham, with particularly strong experience renovating properties in conservation areas where planning sensitivity matters.
Basement Conversions & Loft Extensions
Maximise your Richmond property’s potential without extending your footprint. Our basement developments create incredible living spaces – home cinemas, gyms, playrooms or self-contained guest suites. Loft conversions add valuable bedroom space, perfect for growing families in Richmond’s competitive property market.
Kitchen & Bathroom Renovations
Transform the heart of your home with a bespoke kitchen renovation, or add luxury with an en-suite bathroom installation. We handle design, structural alterations, plumbing, electrics and finishing – coordinating every trade to deliver on time and to budget.
