What sets our garden rooms apart in Cranfield.
Fully Insulated Envelope
150mm PIR or structural SIPs to walls, floor and roof — whole-building U-value 0.18 W/m²K, comfortable in December and cool in July with no bolt-on air-conditioning.
Mains-Powered & Wired
Dedicated RCD-protected consumer unit, ring main, data (Cat6), lighting circuits and optional networked heating — all buried in armoured SWA from the main house by our own electricians.
Heated Year-Round
Panel radiators, low-profile electric underfloor heating or an air-source heat pump — sized to the space so it runs on a fraction of the energy demand of a poorly insulated conservatory.
Bespoke Cladding
Western Red Cedar, thermally-modified Accoya, painted timber, composite or standing-seam aluminium — matched to the palette of your house and garden, not pulled from a catalogue.
Large Aperture Glazing
Full-width aluminium bifolds, slim-frame sliders or fixed picture panes up to 2.7m tall — the front elevation opens the room to the garden the way a summer house never could.
Permitted Development
Most builds fall under PD as an outbuilding: under 2.5m at the eaves, under 3m ridge (pitched roof further than 2m from any boundary). We survey, confirm and, where needed, obtain a lawful development certificate on your behalf.
Turnkey, Single-Point Delivery
Design, foundations, frame, cladding, glazing, electrics, plastering, flooring and decoration — one contract, one named site manager, one aftercare number. No sub-let trades, no gap in accountability.
Plumbed on Request
WC, shower or utility sink runs off the house cold main and drains into the nearest inspection chamber — specified at survey for treatment rooms, gym showers and guest snugs.

Common questions from Cranfield homeowners.
- Do you install garden rooms in Cranfield?
- Yes — South East Windows & Doors installs garden rooms across Cranfield (MK43) and the wider Bedfordshire area every week. Every project is surveyed, manufactured and installed by our own teams.
- How long does garden rooms installation take in Cranfield?
- Most Cranfield projects run to a two-to-eight week lead time from signed quote to install, depending on manufacture. Once on site, a typical garden rooms install completes in one to five working days with full dust-sheet protection and clean-down.
- Do you handle conservation-area planning in Cranfield?
- New-build handovers frequently include basic-specification windows. A Bedfordshire homeowner upgrading to our A+ profile typically sees a measurable improvement in heating bills within a single winter. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Cranfield projects that require them.
- What guarantee covers garden rooms in Cranfield?
- Every garden rooms installation in Cranfield is covered by our insurance-backed 10-year guarantee — parts, labour and finish. Aftercare is direct with the installing team, not a call centre.
- Can I see recent garden rooms work near Cranfield?
- Yes — we can share recent garden rooms case studies from across Bedfordshire, including projects in Wootton, Marston Moretaine and neighbouring towns. Ask your surveyor at the on-site visit.
- Do I need planning permission for a garden room?
- Usually not. Under permitted development, an outbuilding under 2.5m tall at the eaves (or up to 3m ridge if further than 2m from any boundary), not occupying more than 50% of the original garden and not in front of the principal elevation, is permitted. Listed buildings, conservation areas and Article 4 zones need full planning — we handle the application on your behalf.
- How long do they take to build?
- A typical garden room is weathertight within 7–10 days on site and complete in 2–4 weeks from ground-breaking, depending on size, cladding and internal finish. Complex pool-house or plumbed builds run 4–6 weeks.
- Can I use it as a bedroom or Airbnb?
- Occasional overnight use falls under PD as an outbuilding. Regular sleeping accommodation or short-let use makes it a habitable dwelling — Building Regs apply, potentially planning too, and Council Tax implications need advice. We flag the distinction at survey and won't build outside the rules.
