Local Knowledge You Can Trust
Based in Winchester, we understand local property styles, planning requirements, and how to deliver work that fits perfectly with the area’s character.
Reliable, Skilled Craftsmanship
Our team is experienced, qualified and committed to delivering durable, high-quality results. We don’t cut corners — ever.
Stress-Free, Transparent Service
Clear communication, tidy workspaces, and straightforward timelines. No hidden extras and no hassle.
House extensions are one of the most popular ways to create extra space without the cost and disruption of moving. Our Winchester builders design and construct single-storey, double-storey and wrap-around extensions that blend seamlessly with your existing property.
From initial groundworks and structural alterations through to roofing, glazing and internal finishes, we manage the entire build process. Whether you’re expanding your kitchen, adding a family room or creating additional bedrooms, we deliver high-quality extensions that improve both lifestyle and long-term property value across Winchester and surrounding villages.
A loft conversion is a smart way to unlock unused space and add valuable living accommodation. Our team specialises in dormer, hip-to-gable and roof-light loft conversions, tailored to suit Winchester’s mix of period and modern homes.
We handle structural works, insulation, staircases, electrics and plumbing to create bright, comfortable rooms ideal for bedrooms, home offices or guest suites. All loft conversions are completed in line with Building Regulations, ensuring safety, comfort and lasting quality.
Loft Conversions
Garden rooms are increasingly popular for home offices, studios and flexible living space. We design and build fully insulated garden rooms and outbuildings, complete with electrics, heating and high-quality finishes.
Built for year-round use, our garden rooms offer a quiet, comfortable solution for working from home or creating extra usable space without extending the main house. We ensure all work complies with relevant regulations and is built to last.
Kitchen & Bathrooms
If your home feels outdated or no longer suits your needs, a full or partial renovation can completely transform it. We provide comprehensive property renovation services, from layout changes and structural work to modern finishes and energy-efficiency upgrades.
Our Winchester builders have experience renovating older and character properties, carefully balancing modern improvements with original features. Whether it’s a single-room refurbishment or a whole-house renovation, we deliver practical, well-finished spaces designed for modern living.
