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 Kirkby?
In Kirkby, an orangery typically costs £2,250–£3,200 per m² of floor area, including VAT at 20% (standard rate). For a typical 16 m² project that is roughly £36,000–£51,000. The guide for Kirkby reflects typical costs in the North West, roughly 6% below the UK-wide figure. Design, structural calculations and council fees are extra.

- Frame material and colour
- Heating and flooring
- Amount and type of glazing

Do you need planning permission for an orangery in Kirkby?
The approval route for Kirkby is set by planning law 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
