Composite & timber decking in Olney
Decks behind Olney's limestone houses and on its newer edge-of-town estates, with Article 4 and listed building status checked before design.
Decking in Olney typically costs £110–£140 per m² supplied and fitted in softwood timber and £200–£250 per m² in composite, with a 15–20m² composite deck usually £3,000–£5,000. With 119 listed buildings and an Article 4 direction across the conservation area, the first step is checking your address; a deck at a listed house needs consent.

Composite & timber decking in Olney
Olney is a limestone market town with 119 listed buildings and a long conservation area through the centre, surrounded by newer estates, with around 300 more homes allocated in the 2017 neighbourhood plan. Older houses in the centre tend to have long, enclosed gardens behind the street frontage, while the estate homes on the edge have more regular plots. Both suit a deck, and the main difference between them is the planning position, which we check for every Olney address before anything is drawn up.
An Olney deck is costed once we know whether the house is listed and what the ground is like under the planned frame. The build guide is £110–£140 per m² for softwood timber supplied and fitted and £200–£250 per m² for composite, so a 15–20m² composite deck in an Olney garden is usually £3,000–£5,000. Gardens that fall towards the Ouse valley may need a raised deck, and balustrades and steps cost more. We give guide figures first, then a fixed price in writing after a free design visit.
What makes Olney different
Olney sits on Great Oolite limestone, which generally drains better than Milton Keynes clay, though clay bands and the Ouse flood plain change that locally. We check the ground under the planned deck rather than assume. The conservation area has an Article 4 direction for houses removing permitted development for extensions, alterations, porches and painting outside walls; outbuildings are not on that list. The Great Ouse valley runs along the south of the town, and the council notes a cluster of sewer flooding records in Olney.
A typical Olney deck sits in the rear garden of a stone house in the conservation area or behind a newer estate home on the edge of town. The work usually involves confirming listed and Article 4 status, setting pads on the limestone or clay as found, building a low braced frame, laying a membrane and fixing boards, often with a step down to the lawn.

Permissions and checks in Olney
- Step 1Decking in a rear garden is normally permitted development if no part of it is more than 30cm above the ground and, with other outbuildings and platforms, it covers no more than half the garden. A raised deck over 30cm needs planning permission, and a listed house needs consent. Listed buildings and conservation areas in Olney have tighter rules, so we check your address before anything is designed. Planning Portal: decking
- 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 3We check the ground and the planning position at the free design visit and give you one fixed written price.
