What is a wraparound extension?

A wraparound extension combines a side return and a rear extension into one L-shaped addition. It gives the largest possible ground floor, often creating an open-plan kitchen, dining and living space across the whole width of the house.
How much does a wraparound extension cost in Forfar?
In Forfar, a wraparound extension typically costs £2,150–£3,100 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £60,000–£87,000. Prices in Scotland sit near the national average for this kind of work, and the range for Forfar reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a wraparound extension in Forfar?
Approvals for a wraparound extension in Forfar follow the rules for Scotland. In Scotland a wraparound extension normally needs planning permission and a building warrant.
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.
