Garage Conversions
Turn that cold, cluttered garage into warm, practical living space that feels like it’s always belonged. Popular choices include home offices, playrooms, extra bedrooms, gyms, or open-plan kitchen extensions. Our conversions blend seamlessly with your existing home and can add serious value to your property.
We handle every type of space:
– Single garage conversions
– Double garage conversions
– Detached garage conversions
Basement Conversions
Transform a dark, damp basement into a stunning, dry, and versatile part of your home. Ideal for cinema rooms, home gyms, teen dens, self-contained granny annexes, or luxury guest suites. We take care of waterproofing, insulation, lighting, and ventilation so the new space is comfortable all year round.
Our basement services include:
– Full or partial basement conversions
– Change-of-use projects
– Self-contained living units
Loft Conversions
Add valuable upstairs space without eating into your garden. A well-executed loft conversion can give you an extra bedroom with en-suite, a quiet home office, or a relaxing master suite. Many projects fall under permitted development, keeping things simple and swift.
We deliver all popular styles:
– Velux (rooflight) conversions
– Dormer conversions
– Hip-to-gable conversions
– Mansard conversions
