Garden Rooms &
Offices in Somerset

A garden room shouldn’t be a seasonal luxury; it should be a functional, year-round extension of your living or working space. We build architectural-grade garden rooms and offices in Somerset and across the South West.

Our Garden Room Services

We apply the same structural principles to our garden rooms in Somerset as
we do to a full house extension. We focus on permanent foundations, high-performance
insulation, and structural integrity that adds long-term value to your property.

Bespoke Home Offices

We build professional, quiet workspaces designed for year-round remote work. These are fully integrated with your home’s electrical system and include high-speed data cabling, professional lighting, and climate control.

Garden Studios
& Gyms

Whether you need a creative studio or a private fitness suite or gym, we can provide the perfect space. Our designs can include reinforced flooring, acoustic insulation for soundproofing, and durable internal finishes.

Insulated Guest Annexes

When you need extra living space for guests or family, we build guest annexes to the highest standards. These buildings focus on superior damp-proofing and thermal performance, ensuring a warm and comfortable environment.

Storage & Utility Rooms

If you need to combine a workspace with practical storage, we can design split-use buildings for your garden. These allow for a high-finish office on one side and a secure, weather-proof utility or storage area on the other.
