P-shape conservatory orangery conversion cost
A orangery conversion on a medium P-shape conservatory typically costs £14,000 to £35,000, fitted.
A P-shape joins a lean-to to a Victorian bay, giving a long room with a rounded end. The roof has both a single slope and a faceted section, joined by valleys, which makes it one of the more complex roofs to replace.
Orangery conversions on a P-shape conservatory
P-shape to orangery conversions are larger projects and often come with new walls.
- The valley where the two sections meet is a common leak point on old roofs and needs careful detailing on the new one.
- Two zones in one room, often a dining area and a lounge, so lighting and heating are planned for both.
- More roof area and more junctions mean higher prices than a single shape of the same floor area.
