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 Gainsborough?
In Gainsborough, an orangery typically costs £2,300–£3,250 per m² of floor area, including VAT at 20% (standard rate). For a typical 16 m² project that is roughly £37,000–£52,000. Prices across the East Midlands are typically 5% below the UK average for this kind of work, which is reflected in the range for Gainsborough. Design, structural calculations and council fees are extra.

Do you need planning permission for an orangery in Gainsborough?
Approvals for an orangery in Gainsborough follow the rules for 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.
We check this for your address before design work starts, so there are no surprises later.
What we handle
From survey to sign-off, the job normally involves:
- Roof lantern and glazed panels
- French, sliding or bifold doors
- Building control sign-off where required
- Foundations and dwarf walls or piers
- Electrics, heating and plastering
- Flooring and decoration options
How long does it take?
Allow 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.
