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 Gwent?
In Gwent, 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. That range is adjusted for Wales, where domestic building work typically costs around 8% below the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for an orangery in Gwent?
Approvals for an orangery in Gwent follow the rules for 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.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

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.
Can an orangery replace a conservatory?
Yes. We can remove an old conservatory and build an orangery on new or upgraded foundations.

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.
