Building Services Across Richmond-upon-Thames
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.

The JNJ Approach: No Surprises, Just Results

We provide detailed, itemised quotes before work begins – no hidden costs, no unexpected bills. Your dedicated project manager keeps you informed weekly (or daily if preferred), so you always know exactly where your build stands.
Considerate Construction
As approved members of the Considerate Constructors Scheme, we take neighbourhood impact seriously. Clean sites, respectful working hours, and minimal disruption to Richmond residents – including managing parking, noise and waste responsibly.
Award-Winning Design & Build Quality
Our work has earned recognition across West London, but what matters most is delivering exactly what we promise. That degree of pride in the finish? It’s not marketing speak – it’s how we operate.
