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 Strabane?
In Strabane, an orangery typically costs £2,050–£2,900 per m² of floor area, including VAT at 20% (standard rate). For a typical 16 m² project that is roughly £33,000–£46,500. That range is adjusted for Northern Ireland, where domestic building work typically costs around 14% below the national average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (11 m²) | £22,500–£32,000 |
| Typical project (16 m²) | £33,000–£46,500 |
| Larger project (22 m²) | £45,000–£64,000 |
| Rate per m² | £2,050–£2,900 |
The main things that change the cost:
- Heating and flooring
- Lantern size
- Opening into the house
- Amount and type of glazing
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for an orangery in Strabane?
Approvals for an orangery in Strabane follow the rules for Northern Ireland. In Northern Ireland the Planning (General Permitted Development) Order (Northern Ireland) 2015 allows single-storey rear extensions of up to 3 metres on attached houses and 4 metres on detached houses, no higher than 4 metres, with eaves no higher than 3 metres within 2 metres of a boundary. Houses with removed rights need planning permission, listed buildings need consent, and in conservation areas extensions must stay single-storey and must not come forward of the front or side walls.
Northern Ireland has no Party Wall Act. Work on shared walls relies on agreement with the neighbour and common law, so we agree the arrangements in writing before work starts.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
