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 Holyhead?
In Holyhead, 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.

Do you need planning permission for an orangery in Holyhead?
The approval route for Holyhead 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.
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.
We check this for your address before design work starts, so there are no surprises later.

Questions about orangeries in Holyhead
Does an orangery need building regulations approval?
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.
Can an orangery replace a conservatory?
Yes. We can remove an old conservatory and build an orangery on new or upgraded foundations.
Do you build orangeries in Holyhead?
Yes. We build orangeries across Holyhead, including postcodes LL65. Every project starts with a free home visit.
What is the difference between an orangery and a conservatory?
An orangery has a solid roof around a central lantern and more brickwork, while a conservatory is mostly glazed. Orangeries are usually warmer in winter and cooler in summer.
