Garden & Live Rooms

Year-round rooms, in the garden .

Architect-designed garden offices, studios and live rooms across Cheshire and Greater Manchester. Fully insulated, with heating, power and data — built to residential standards, not summerhouse shortcuts.

Why Choose Us

Not a kit. A proper room.

The garden rooms you see flat-packed on a driveway aren\'t what we build. Ours are bespoke timber-frame structures with full building-regulation-grade insulation, airtight membranes, double-glazed aluminium-framed doors and a heating strategy for the real North West winter — not just a summer evening with a coat on.

Home offices, yoga studios, music rooms, guest annexes, garden kitchens. Whatever the brief, the underlying construction is the same standard we\'d build into any extension on the side of your house.

Frequently Asked

Garden Room FAQs.

What people ask us most often about garden and live rooms.

Do I need planning permission for a garden room?

Most garden rooms under 2.5m in height and at least 2m from a boundary fall under Permitted Development. Rooms with sleeping or living accommodation, or in a conservation area, usually do need formal consent. We check eligibility on the free site visit.

How much does a garden room cost?

Entry-level insulated garden offices start around £18,000. Fully glazed year-round live rooms with bathroom, AC and high-spec finishes typically run £32,000–£65,000+ depending on size and specification.

Can I use it as a bedroom or Airbnb?

Usually — but it becomes an "outbuilding with living accommodation" which takes it outside Permitted Development. We'd apply for formal planning consent and build to full residential standards, including fire detection and building regs sign-off.

How long does installation take?

A typical 4m × 5m insulated garden room runs 4–6 weeks on site, from base pour to final handover. Larger live rooms with glazing and services take 6–10 weeks.

Do I get heating, power and Wi-Fi?

Power and lighting are standard. We fit underfloor or wall-mounted electric heating, air-con units, and run a dedicated Cat6 cable back to your router for reliable Wi-Fi.

What warranty do I get?

10-year structural and roofing warranty as standard, plus manufacturer warranties on glazing, heating and AC units.
