Glass verandas in Olney
Verandas for Olney's limestone town houses and edge-of-town estates, with planning permission handled where the Article 4 direction applies.
A glass veranda in Olney typically costs £9,000–£14,000 supplied and fitted for 4m × 3m, or £15,000–£22,000 for 6m × 3m, with extras on top. The key local fact is Olney's Article 4 direction: it removes permitted development for extensions in the conservation area, so a veranda fixed to a house there needs planning permission.

Glass verandas in Olney
Olney is a limestone market town with 119 listed buildings and a long conservation area through the centre, plus newer estates around the edge. Where you live in the town decides how a veranda project runs. On the estates it is usually permitted development; in the conservation area, Olney's Article 4 direction means a planning application comes first. We explain which applies on a free design visit, then design an aluminium-framed glass or polycarbonate roof to suit the house.
Our guide prices are the same across the area: a 4m × 3m aluminium and glass veranda typically costs £9,000–£14,000 supplied and fitted, and a 6m × 3m £15,000–£22,000. Screens, lighting and heaters are priced on top. If your house needs planning permission, we tell you at the start and the drawing is prepared with an application in mind, so the design does not have to be redone later. Your fixed price then comes in writing.
What makes Olney different
Olney's conservation area has an Article 4 direction for houses that removes permitted development for extensions, alterations, porches and painting outside walls. Because a veranda fixed to the house is treated like a single storey rear extension, one inside the conservation area needs planning permission. Listed houses need consent too. Underfoot, Olney sits on Great Oolite limestone, which generally drains better than Milton Keynes clay, but clay bands and the Ouse flood plain change that locally, so we do a percolation test before designing a soakaway.
A typical Olney veranda either covers a patio behind a newer house on the edge of town, where it is usually straightforward, or sits behind a stone house in the centre after planning permission. The job involves fixing a wall plate and flashing, setting footings into limestone or clay bands, testing drainage for the downpipe and fitting the roof. Frame colour is often chosen to suit stone.

Permissions and checks in Olney
- Step 1A veranda fixed to the house is treated like a single storey rear extension: usually permitted development if it stays within the extension depth and height limits, does not face a road and is not on a listed house. Open-sided verandas under 30m² are usually exempt from building regulations. Olney’s Article 4 direction removes permitted development for extensions in the conservation area, so a veranda fixed to the house there needs planning permission. Planning Portal: extensions
- Step 2Trees in a conservation area need six weeks’ written notice before any work, and trees with a Tree Preservation Order need consent — both are free. Milton Keynes City Council: tree protection
- Step 3An open-sided veranda under 30m² is usually exempt from building regulations. Closing it in with glass walls can change that, so we check with building control first.
- Step 4We check the ground and the planning position at the free design visit and give you one fixed written price.
