What is an orangery?

An orangery is an extension with brick or block piers, large areas of glazing and a solid perimeter roof around a central roof lantern. It sits between a conservatory and a traditional extension: brighter than an extension, warmer and more private than a conservatory.
How much does an orangery cost in Haverfordwest?
In Haverfordwest, an orangery typically costs £2,200–£3,150 per m² of floor area, including VAT at 20% (standard rate). For a typical 16 m² project that is roughly £35,000–£50,500. We start from a UK-wide guide and adjust it for Wales, where labour and materials are typically about 8% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (11 m²) | £24,000–£34,500 |
| Typical project (16 m²) | £35,000–£50,500 |
| Larger project (22 m²) | £48,500–£69,500 |
| Rate per m² | £2,200–£3,150 |
The biggest cost drivers are:
- Amount and type of glazing
- Lantern size
- Opening into the house
- Heating and flooring

Do you need planning permission for an orangery in Haverfordwest?
Before anything is built in Haverfordwest, we confirm which approvals apply in Wales. In Wales a single-storey rear extension is often permitted development: up to 4 metres beyond the rear wall and up to 4 metres high, with eaves no higher than 3 metres within 2 metres of a boundary and no more than half the land around the original house covered. Wales has no larger home extension prior approval route, so deeper extensions need a planning application, as do extensions to flats, listed buildings and houses whose rights have been removed.
The Party Wall etc. Act 1996 applies in Wales, so notices must be served before work on a shared wall, on the boundary, or excavation close to a neighbour’s foundations.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.

If it is open to the house or does not meet the conservatory exemption, yes. Most orangeries are treated as extensions and need building control approval, which we arrange.
