Conservatories vs Orangeries vs Extensions

All three add space and light, but they differ in construction, feel and cost.

Conservatory

Predominantly glazed walls and roof on a dwarf wall or full-height glass. The most affordable way to add a bright garden room; modern glazing and roofs make them usable far more of the year than older ones. See conservatory specialists.

Orangery

A hybrid with more substantial brick or rendered pillars and a flat perimeter roof around a central glazed lantern — a more solid, “room-like” feel that blends house and garden room.

Extension

A conventional building with a solid roof and walls, often with large glazed doors or a roof lantern. The most expensive but the most seamless addition to the living space.

Planning and building regs

Many conservatories are permitted development within size limits; orangeries and extensions more often need full approval. Always confirm with your council and use a builder who handles compliance.

Frequently asked questions

Is a conservatory cold in winter?

Modern glazing, a warm roof and good doors make today’s conservatories usable year-round, unlike older polycarbonate-roofed ones.

Which adds the most value?

A well-built extension or orangery usually adds the most, but a quality conservatory still improves saleability and liveable space.
