Single-Storey Extensions

Ideal for kitchen-diners, family rooms, or utility spaces, single-storey extensions offer extra ground-floor living space while keeping your build simple and efficient. Whether it’s a rear extension to open up your garden or a side addition to create more flow — we’ve got it covered.

Double-Storey Extensions

Need extra space upstairs and down? A two-storey extension gives you maximum living area and added value, perfect for growing families who need additional bedrooms, bathrooms, or study areas.

Rear Extensions

Open up the back of your home for a modern kitchen-diner, open-plan lounge, or garden-facing living space. Perfect for entertaining or bringing in more natural light.

Side Extensions & Wraparounds

Make use of unused side land or create a larger L-shaped floor plan by combining side and rear extensions. This is a great way to create space without taking up too much of your garden.

Garage Conversions & Extensions

Transform your garage into a fully functional room — ideal for an office, gym, bedroom, or playroom. We can also build new attached or detached garages tailored to your space and needs.
