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 Gosport?
In Gosport, 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. That range is adjusted for the South East, where domestic building work typically costs around 12% above the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for an orangery in Gosport?
Here is how the rules work for an orangery 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.
We check this for your address before design work starts, so there are no surprises later.

Questions about orangeries in Gosport
Do you build orangeries in Gosport?
Yes. We build orangeries across Gosport, including postcodes PO12. Every project starts with a free home visit.
Can it be used all year?
Yes. With an insulated roof, efficient glazing and heating, an orangery is comfortable all year.
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.
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.
