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 Abergavenny?
In Abergavenny, 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. Prices across Wales are typically 8% below the UK average for this kind of work, which is reflected in the range for Abergavenny. Design, structural calculations and council fees are extra.

Do you need planning permission for an orangery in Abergavenny?
The approval route for Abergavenny is set by planning law 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.
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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

Who approves an orangery in Abergavenny?
Planning matters in Abergavenny go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
How long does it take?
Typically 8 to 12 weeks on site once approvals are in place.

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.
