Bespoke Garden Rooms

Your garden,
transformed.

Fully-insulated, bespoke garden rooms designed and built to a standard that rivals your home — offices, studios, games rooms, bars and more.

About Us

Not just a shed.
Not even close.

Not everyone has a dedicated space in their home for entertaining — and it's only the lucky few who have room for a pool table, table tennis table or bar. If you have teenagers at home, finding space for everyone to relax gets even harder.

Our garden rooms are fully-fledged, timber-framed buildings — the thermal efficiency ratings of our structures may well exceed those of your house. These are spaces designed to be lived in, year-round.

Want a built-in bar? Reinforced floor? Audio-visual connections? Custom cladding in any of 21 colours? We'll make it happen.

Garden Room vs Extension

The smarter way
to add space.

A home extension and a garden room both add space — but the similarities end there. For most homeowners, a garden room delivers the same quality of life improvement in weeks rather than months, and at a fraction of the cost.

Garden Room Extension
Typical cost £12k – £35k £45k – £85k+
Cost per m² £1,200 – £2,500 £2,200 – £3,200
Build time 1 – 3 weeks 12 – 26 weeks
Planning permission Often not required Usually required
Adds to property value 5% – 15% 10% – 20%

UK 2026 benchmarks. Figures are indicative.

1
Done in weeks, not months

Most garden rooms are installed in one to three weeks. The work happens entirely outside — no dust, no builders tramping through your home, no months of disruption to daily life.

2
Significantly better value

No complex groundwork, no structural alterations to your home, no party wall agreements. The result is a fully-insulated, high-quality space at a fraction of extension costs.

3
A space that's truly separate

There's real value in a room with a physical boundary. Whether it's a home office, gym or studio, the short walk outside creates the mental separation that a room inside the house never can.

4
Planning is usually straightforward

Most garden rooms fall under Permitted Development — single-storey, under 2.5m at the boundary, covering no more than 50% of your garden. We'll advise you from the outset.
