A good extension does more than create extra room. It changes how your home feels and functions day to day. Rear, side-return, wraparound, double-storey: whatever suits your property, we build it around how you actually live.
Our Architectural Service Covers:
Rear & Side extensions
Perfect for expanding kitchens, dining areas, and open-plan living spaces with seamless garden access.
Double-Storey Extensions
Add extra bedrooms, bathrooms, or a home office upstairs without losing outdoor space.
Wraparound Extensions
Maximise your footprint with intelligent, integrated builds that dramatically enhance layout and flow.
Planning & Building Regulations
We handle all planning applications, drawings, and compliance — so you don’t have to worry about red tape.
Interior Design & Finishing
We don’t just build walls — we complete the look. Flooring, lighting, plastering, and more, all under one roof.
Basement & Loft Integration
Looking to combine vertical expansion with horizontal? We can advise on full-space transformations.
