Built any time of year — winter slows the foundation pour but rarely stops it. ### Why It Matters Garden rooms either become the most-used room in the property or rot in the corner of the garden inside five years. The difference is the build spec: proper foundation, full insulation envelope, EPDM warm roof, mains electrics — not a glorified shed with a heater. What Happens If You Wait ## The Cost OfDoing Nothing. Cheap garden rooms fail predictably. The roof leaks at the parapet, the floor goes cold, the cladding twists, and the electrics were always undersized. ### Risks Of Ignoring It →Single-skin uninsulated build — usable in summer, unusable November to March. - →Felt or torch-on roof on a flat deck without falls — pools water, fails in three winters. - →Cladding fitted direct to sheathing with no ventilation cavity — moisture trapped, boards rot from behind. - →Spur off a 13A socket for power — trips constantly under heater or PC load, no certificate. - →No DPC or insulated floor — cold strikes up, condensation under furniture. ### Common Mistakes Customers Make - ×Buying a flat-pack from the cheapest online supplier and self-erecting — site spec rarely matches PD rules. - ×Going under-spec on insulation to save a few hundred pounds — costs more in heating across one winter. - ×Skipping the dedicated circuit from the consumer unit — power problems forever. - ×Building closer than 2m to the boundary with combustible cladding — Permitted Development breach.

Working across Manchester · Cheshire · Oldham · Salford · Stockport · Alderley Edge · Altrincham & Hale Full Service Area Map ### Home Office Garden Rooms The most common build — typically 3m x 4m, fully insulated, mains electrics, data run from house, heating sized for the floor area. Built to use 8 hours a day, 5 days a week, every week of the year. ### Garden Gyms & Studios Reinforced floor for racks and free weights, electrics sized for treadmills / cable machines, mirror wall, ventilation specced for sweat and moisture. Studios for yoga, music, painting and dance all built to the same standard. ### Annexes & Multi-Generational Use Larger garden rooms with kitchenette and shower room — note Permitted Development limits on independent living. We tell you straight at feasibility what's permissible without full planning. ### Foundations & Site Conditions Concrete pad and ring beam for typical Manchester clay; screw piles on tree-root influence zones or for minimum-impact installation; raft slab on softer ground. Engineer's design where the site warrants it. ### Permitted Development & Planning Most garden rooms fall under Permitted Development — height limits, volume limits and boundary distances apply. Lawful Development Certificate strongly recommended for resale. We confirm at survey. Questions ## StraightAnswers. Cost, timeline, guarantees, lifespan, emergency availability — the questions everyone asks, answered before you call. Ask Yours ### How much does a garden room cost in Manchester? +Greater Manchester 2026: typical 3m x 4m insulated garden office £18,000–£28,000 including foundation, mains electrics and finished interior. Larger or higher-spec studios £28,000–£45,000. Fixed itemised written quote. ### Do I need planning permission? +Usually no — most fall under Permitted Development (height under 2.5m within 2m of boundary, volume limits, no sleeping accommodation as independent dwelling). A Lawful Development Certificate is recommended for resale. We confirm at survey. ### How long does it take to build? +Typically 3–5 weeks from foundation to handover, depending on size, cladding and ground conditions. ### Can you wire it into the house properly? +Yes — dedicated circuit from the house consumer unit, RCD-protected, armoured cable run buried to depth, NAPIT-registered specialist with certificate issued on completion. ### Is it warm enough to use in winter? +Yes — full insulation envelope (floor, walls, roof), triple-glazed door and windows, heating sized for the floor area. Most clients use a panel heater or air-con as the heat source. ### Can I have a toilet or kitchenette in it? +Yes — drainage and water run from the house, tanked wet zone, certified electrics. Note that adding sleeping accommodation with full kitchen and bathroom can take the building out of Permitted Development. ### Do you guarantee the work? +Yes — up to 5 years on internal renovation defects, written into the contract. EPDM roof carries a 20+ year material warranty. ### Do you cover all of Greater Manchester and Cheshire? +Yes — Manchester, Salford, Stockport, Trafford, Cheshire and surrounding towns. ### What cladding options do you offer? +Larch (silvers naturally), cedar (warm tone, holds colour with treatment), composite (low-maintenance), painted timber.
