Conservatory vs Orangery vs Extension
Conservatory — Mostly glazed walls and roof. Cheapest option. Can be too hot in summer and cold in winter without modern glazing.
Orangery — Brick pillars with a flat perimeter roof and central glass lantern. Better insulation than a conservatory, more premium feel.
Extension — Solid walls and conventional roof. Most expensive but best thermal performance and year-round usability. Usually requires planning permission.
The key factor: conservatory roof replacement (polycarbonate to solid tiles or glass) typically costs £3,000–£8,000 and transforms an existing conservatory into a year-round room.
