Garden Rooms designed around orangeries and garden rooms in Cotswold gardens and Thames-side plots.
Bicester has expanded faster than almost any town in the county. We frequently upgrade new-build windows fitted with basic glazing specifications, and we handle full-house replacements on older stock in the town centre and surrounding villages.

What sets our garden rooms apart in Bicester.
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.
What Bicester homeowners tell us.
"A 5m aluminium bifold set opening onto the paddock. Perfectly level, perfectly aligned, and a joy to use."
"Composite front door in a bespoke dark green with brushed brass. It's the front-of-house detail the property was missing."
"Fair, honest, considered advice. They talked us into the right specification, not the most elaborate."
Common questions from Bicester homeowners.
- Do you install garden rooms in Bicester?
- Yes — South East Windows & Doors installs garden rooms across Bicester (OX25 – OX27) and the wider Oxfordshire area every week. Every project is surveyed, manufactured and installed by our own teams.
- How long does garden rooms installation take in Bicester?
- Most Bicester 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 Bicester?
- Oxfordshire combines designated heritage areas, AONB villages and new-build growth. Our painted flush casements and slim aluminium bifolds balance conservation sensitivities with modern thermal performance. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Bicester projects that require them.
- What guarantee covers garden rooms in Bicester?
- Every garden rooms installation in Bicester 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 Bicester?
- Yes — we can share recent garden rooms case studies from across Oxfordshire, including projects in Kingsmere, Elmsbrook 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.
