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 Sandown?
In Sandown, an orangery typically costs £2,700–£3,800 per m² of floor area, including VAT at 20% (standard rate). For a typical 16 m² project that is roughly £43,000–£61,000. Island and remote projects usually cost more than this guide because of shipping, travel and accommodation. Design, structural calculations and council fees are extra.

Do you need planning permission for an orangery in Sandown?
Whether you need planning permission depends on your house and its location 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.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
On a typical orangery we handle:
- Roof lantern and glazed panels
- Design to suit the style of the house
- Foundations and dwarf walls or piers
- Building control sign-off where required
- Insulated perimeter roof with internal pelmet
- Flooring and decoration options
How long does it take?
Build time is typically 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.

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