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 Grangemouth?
In Grangemouth, an orangery typically costs £2,350–£3,300 per m² of floor area, including VAT at 20% (standard rate). For a typical 16 m² project that is roughly £37,500–£53,000. Building costs in Scotland are close to the UK average, so the figures for Grangemouth are close to our national guide. Design, structural calculations and council fees are extra.

Do you need planning permission for an orangery in Grangemouth?
Whether you need planning permission depends on your house and its location in Scotland. In Scotland a single-storey extension is often permitted development (Class 1A): where any part is within 1 metre of a boundary, it can project up to 3 metres from the rear wall of a terraced house or 4 metres on other houses, with eaves no higher than 3 metres, an overall height of 4 metres and no more than half the front or rear garden covered. The rights do not apply in conservation areas or to flats, and a building warrant will usually still be needed before work starts.
Scotland has no Party Wall Act. Work on shared walls is governed by your title deeds, the Tenements (Scotland) Act 2004 for flats, and common law, so we agree arrangements with neighbours in writing before work starts.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

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.

Planning matters in Grangemouth go to the council covering your address, and the work needs a building warrant. We prepare and submit the applications for you.
