P-shape Conservatories in London
Two conservatories in one. A P-shape combines a Victorian faceted bay end with a longer lean-to leg, meeting at a T-junction — a dining zone and a sitting zone, or a garden room and a home office, side by side under a single continuous roof.
P-shape Conservatories designed around compact rear gardens, party-wall etiquette and permit-parking logistics.
From Chelsea townhouses to Hampstead villas and Ruislip family homes, we install across every London borough — inside the M25 and out. Our surveyors know the quirks of Victorian sashes, Edwardian bays and post-war casements.
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.
Tiled and hybrid warm-roof conservatories across London achieve roof U-values of 1.0–1.4 W/m²K for improved year-round thermal performance.
What sets our p-shape conservatories apart in London.
Two Zones, One Roof
The faceted end reads as a distinct room-within-a-room; the lean-to leg carries the everyday circulation and additional seating.
Ideal for Larger Homes
P-shapes typically run 6–9m along the elevation — comfortable for detached and semi-detached properties with a substantial rear garden.
Structural T-Junction
The junction where the two roof geometries meet is engineer-calc'd with a hidden structural ridge — no visible tie or valley beam inside.
Zoned Heating Options
Independent thermostat and UFH zones let you heat the two ends of the room separately — sitting warm, dining ambient, or vice versa.
Any Material, Any Finish
Reinforced uPVC in white or cream for a traditional look; thermally-broken aluminium in any RAL for a contemporary specification.

Common questions from London homeowners.
- What size home suits a P-shape?
- Larger detached or semi-detached houses — the shape needs 6m+ of elevation to work properly. On narrower plots a lean-to or Edwardian is a better fit.
- How does a P-shape compare with an Edwardian of the same footprint?
- A P-shape uses a structural T-junction and additional roof geometry to create two distinct zones. An Edwardian uses a simpler square or rectangular plan. We discuss both layouts at survey.
- Can the two zones have different roofs?
- Yes — a fully-glazed Victorian bay end paired with a warm-roof lean-to leg is a popular specification, giving light on one end and TV-friendly shade on the other.
- Do P-shapes need planning permission?
- More often than the smaller styles — the footprint is usually large enough to push above the permitted development thresholds. We handle the full planning submission where required.
