Orangeries designed around compact rear gardens, party-wall etiquette and permit-parking logistics.
Marylebone's Georgian townhouses off the High Street and the Portland-stone mansion blocks along Marylebone Road need timber-alike sightlines. We install throughout W1 and NW1 with drawings prepared for Westminster planners and managing agents.

Postcode-covered: NW1, W1
Weekly installs across NW1, W1 and the surrounding London area, with parking, protection and clean-down handled by our own crews. Insurance-backed 10-year guarantee on every orangeries project.
What sets our orangeries apart in Marylebone.
Structural Brick Piers
Load-bearing corner piers built in a brick or stone matched to the host elevation — the orangery reads as an extension of the house, not a bolted-on room.
Central Roof Lantern
A raised glazed lantern above a flat perimeter roof floods the room with overhead light while keeping the ceiling low and intimate around the walls.
Full Building Regs Room
Because there's no external-quality separating door, an orangery is a heated habitable room under Building Regs — usable as an open-plan kitchen, living or dining space.
Cornicing & Downlights
The flat perimeter roof lets us run plaster cornicing, downlights and even pendant fittings — details a fully-glazed conservatory can't accommodate.
Bifolds or Sliders as Standard
Full-width bifolds or slim-frame sliders along the garden face turn the orangery into a seamless indoor-outdoor room in summer.
What Marylebone homeowners tell us.
"Four quotes, one honest conversation. Their surveyor spent two hours explaining trade-offs — no other firm came close on either detail or clarity."
"Nine windows swapped across a Victorian first-floor flat. Zero mess, done in three days, and the acoustic laminate has genuinely changed how we sleep."
"The sliding sashes are indistinguishable from the originals — the conservation officer signed off first time. Immaculate site management too."
Common questions from Marylebone homeowners.
- Do you install orangeries in Marylebone?
- Yes — South East Windows & Doors installs orangeries across Marylebone (NW1, W1) and the wider London area every week. Every project is surveyed, manufactured and installed by our own teams.
- How long does orangeries installation take in Marylebone?
- Most Marylebone projects run to a two-to-eight week lead time from signed quote to install, depending on manufacture. Once on site, a typical orangeries install completes in one to five working days with full dust-sheet protection and clean-down.
- Do you handle conservation-area planning in Marylebone?
- Working across London means understanding period detail, party-wall etiquette and permit parking as well as we understand glass. We schedule dust sheets, protection and clean-down like a good building firm should. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Marylebone projects that require them.
- What guarantee covers orangeries in Marylebone?
- Every orangeries installation in Marylebone 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 orangeries work near Marylebone?
- Yes — we can share recent orangeries case studies from across London, including projects in Marylebone Village, Portman Estate and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does orangeries achieve in Marylebone?
- Tiled and hybrid warm-roof conservatories across Marylebone, London achieve roof U-values of 1.0–1.4 W/m²K for improved year-round thermal performance.
- Orangery or conservatory — what's the practical difference?
- An orangery has substantial masonry walls or piers and a flat perimeter roof with a glazed lantern; a conservatory is predominantly glazed with a fully-glazed pitched roof. An orangery feels like a room; a conservatory feels like a light-filled garden building.
- Does an orangery need Building Regs approval?
- Yes — because it's typically open to the main house without a separating door, it counts as a habitable room and needs Building Regs sign-off. We handle the submission.
- How does an orangery differ from an Edwardian conservatory?
- An orangery uses substantial brickwork, deeper foundations and a Building Regulations specification, creating a more room-like interior with a central roof lantern. An Edwardian is more fully glazed with a hipped roof.
