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 Glasgow?
In Glasgow, 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. Building costs in Scotland are close to the UK average, so the figures for Glasgow are close to our national guide. Design, structural calculations and council fees are extra.

- Total footprint and the amount of glazing
- Steelwork and propping of the existing house

Do you need planning permission for a wraparound extension in Glasgow?
Whether you need planning permission depends on your house and its location in Scotland. In Scotland a wraparound extension normally needs planning permission and a building warrant.
In Scotland a building warrant is needed before work starts on most extensions, loft conversions and conversions. It is issued by the council’s building standards service. When the work is finished, a completion certificate is submitted and accepted by the council after inspection.
We check this for your address before design work starts, so there are no surprises later.

Who approves a wraparound extension in Glasgow?

What about the old back addition?
The side wall of the back addition is usually removed and replaced with a steel beam, so the old kitchen joins the new space.
Can we keep a separate living room?
Yes. Many clients keep the front room separate and open up only the back of the house.
Is a wraparound worth it?
It gives the biggest ground-floor space without going upwards. Whether it adds value depends on your street and house, so we suggest checking local sale prices before committing.
