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.
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.
A garden room that's usable in February as well as July. Full insulation, proper electrical supply, heating, and drainage where needed — not bolted-on afterthoughts.
CAD drawings tailored to the plot, your brief and planning constraints — not a catalogue kit.
SIPs or studwork timber frame with high-spec PIR insulation, airtight membrane and breather layer.

What people ask us most often about garden and live rooms.
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.
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.
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.
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.
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.
10-year structural and roofing warranty as standard, plus manufacturer warranties on glazing, heating and AC units.
