How People Use Them

Spaces That Work As Hard As You Do

Home Office

Separate your work from home life without a commute. A garden office gives you the focus of an office with the convenience of home, broadband ready, ergonomic, and yours.

Broadband ready CAT6 cabling Climate controlled

Art Studio

Natural north light, plenty of ventilation, and a space where mess is acceptable. We can specify large roof lights, sink points, and robust flooring to suit a working studio.

Roof lights Sink point Vinyl or concrete floor

Games Room

The ultimate retreat for teenagers or adults, a soundproofed, climate-controlled space for gaming, pool, table tennis, or whatever takes your fancy.

Soundproofing options High-power electrics Durable flooring

Yoga & Wellness

A serene, private space for yoga, meditation, or massage therapy. We can fit underfloor heating, Japanese-style sliding screens, and specialist acoustic panels.

Underfloor heating Natural materials Acoustic lining

Music Studio

Acoustic treatment, ventilation that doesn't create noise, and enough power for a full studio rig. We've built recording spaces for professional and amateur musicians alike.

Acoustic insulation Floating floor Studio-grade ventilation

Library & Reading Room

A quiet space for books, reading, and thinking. Floor-to-ceiling shelving, wood-burning stove, and a view of the garden, some of the most satisfying rooms we've built.

Client Reviews

What Our Customers Say

Common Questions

Insulated Garden Rooms FAQ

We insulate to Part L Building Regulations standards or better, typically a U-value of 0.18 W/m²K in walls, 0.15 in the floor, and 0.13 in the roof. We use Kingspan Kooltherm or equivalent PIR foam board in most applications, sometimes combined with mineral wool quilt in the stud cavity for acoustic performance.

Yes, any new electrical circuit from your home to a garden building requires a Building Regulations notification. Our electrical subcontractor is NICEIC Approved, which means they can self-certify the work under Part P without you needing to apply separately to your local authority. We handle all of this as part of the build and provide the electrical installation certificate at handover.

We offer composite cladding (including Trex, long-lasting and zero maintenance), western red cedar (beautiful, requires occasional oiling), and rendered board with silicone render (contemporary, house-extension aesthetic). We can also mix cladding types for a feature elevation, for example, cedar on the front and composite on the sides. We'll show you physical samples at the consultation.

Yes, a well-built garden room typically adds 5–8% to property value, according to estate agent surveys. The key is quality: a properly built, insulated room is counted as usable living space by buyers. A poorly built shed is not. Our builds are finished to a standard that estate agents and surveyors recognise as a genuine improvement to the property.

Every garden room is bespoke, we build to your exact dimensions rather than selling off-the-shelf sizes. Our smallest builds are around 10m² (e.g. 3m × 3.5m) and our largest have been over 50m². We'll advise on the most efficient sizing for your garden and brief, including what can be achieved within Permitted Development limits.
