Tailored Extension Options

We design and build a range of high-quality extensions that are customised to suit your home’s layout and your family’s needs:

Rear extensions – Ideal for extending kitchens or living rooms into the garden and creating open-plan family spaces

Side return extensions – Make use of underutilised side space to increase your interior footprint

Wraparound extensions – A combination of side and rear additions to dramatically expand ground floor living areas

Double-storey extensions – Add new rooms across two floors, perfect for growing families or reconfiguring your home

Over-structure extensions – Build above garages or single-storey areas without compromising outdoor space

Orangeries and garden rooms – Light-filled, versatile spaces that connect indoor and outdoor living
