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 Cirencester?
In Cirencester, an orangery typically costs £2,450–£3,450 per m² of floor area, including VAT at 20% (standard rate). For a typical 16 m² project that is roughly £39,000–£55,000. Prices in the South West sit near the national average for this kind of work, and the range for Cirencester reflects that. Design, structural calculations and council fees are extra.

Your quote will depend mainly on:
- Lantern size
- Frame material and colour
- Amount and type of glazing
- Size and shape of the footprint
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 Cirencester?
Before anything is built in Cirencester, we confirm which approvals apply in England. In England a single-storey rear extension is often permitted development: broadly up to 3 metres deep on a semi-detached or terraced house and 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres within 2 metres of a boundary, and covering no more than half the garden. The larger home extension scheme allows up to 6 or 8 metres if you notify the council first and neighbours have a chance to comment. In conservation areas, National Parks and National Landscapes the larger home extension route, side extensions and cladding are not permitted development. Flats and houses whose rights have been removed need a planning application, and listed buildings need listed building consent.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
