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 Dunoon?
In Dunoon, 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. 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 Dunoon?
The approval route for Dunoon is set by planning law 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.
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:
- French, sliding or bifold doors
- Design to suit the style of the house
- Foundations and dwarf walls or piers
- Flooring and decoration options
- Building control sign-off where required
- Insulated perimeter roof with internal pelmet
How long does it take?
The build itself usually takes 8 to 12 weeks on site. Design and approvals come first and typically take 6 to 12 weeks, depending on the approval route.
