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 Blackwood?
In Blackwood, 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. The guide for Blackwood reflects typical costs in Wales, roughly 8% below the UK-wide figure. 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 |
Your quote will depend mainly on:
- Frame material and colour
- Amount and type of glazing
- Size and shape of the footprint
- Lantern size
Use the guide price tool to see how size and specification change the figure, then ask for a written, itemised quote.
Do you need planning permission for an orangery in Blackwood?
Here is how the rules work for an orangery 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
What we handle
On a typical orangery we handle:
- Design to suit the style of the house
- Insulated perimeter roof with internal pelmet
- Building control sign-off where required
- Electrics, heating and plastering
- French, sliding or bifold doors
- Flooring and decoration options
How long does it take?
The build itself usually takes 8 to 12 weeks on site. Before that, surveys, drawings and approvals usually take 6 to 12 weeks, longer if the council asks for changes.
Building in Blackwood
Wales has many terraced valley streets, stone cottages and post-war estates, so extension designs are shaped by slopes, materials and local character.
We work across Blackwood and neighbouring areas such as Risca, Caerphilly and Pontypridd. Postcodes we cover in Blackwood include NP12.

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.
How much does an orangery cost in Blackwood?
In Blackwood, an orangery typically costs £2,200–£3,150 per m² of floor area, including VAT at 20% (standard rate). A typical 16 m² project comes to roughly £35,000–£50,500. Your fixed price depends on the survey and drawings.
How long does it take?
Typically 8 to 12 weeks on site once approvals are in place.
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.
