Composite & timber decking in Towcester
Decks for Towcester's old town yards, suburban streets and the Towcester South homes, built for clay ground and the Tove flood plain.
Composite decking in Towcester typically costs £200–£250 per m² supplied and fitted and softwood timber £110–£140 per m², with a 15–20m² composite deck usually £3,000–£5,000. In the old centre, the key consideration is slow-draining Lias clay and the Tove flood plain on three sides, so drainage beneath the frame and a flood map check come first.

Composite & timber decking in Towcester
Towcester is a Watling Street coaching town of ironstone, limestone and red brick built right up to the pavement, with yards behind, suburban streets where parking has taken over many front gardens, and the 2,750-home Towcester South extension to the south. In the old town, the rear yard is the only private outdoor space, and a deck can turn an uneven yard into a level seating area. In the suburbs and on Towcester South, decks more often extend a patio onto the lawn.
Towcester is in West Northamptonshire Council's area, and our guide prices are the same in the old town as on Towcester South. Composite comes to £200–£250 per m² supplied and fitted and softwood decking to £110–£140 per m², so a 15–20m² composite deck in a suburban garden is usually £3,000–£5,000, while an old town yard deck is often smaller. Raising a deck, with the balustrades and steps that come with it, costs more. We visit for free, check the ground and flood map, then give you a fixed price in writing.
What makes Towcester different
The old town sits on a clay spur of Upper Lias between the Tove and Silverstone Brook, with limestone and Northampton Sand on the valley sides and boulder clay higher up. In the centre, expect slow-draining clay, so drainage beneath the deck is designed in; on the slopes it is better. The old core is surrounded on three sides by the Tove flood plain. The conservation area's 1998 Article 4 direction applies to frontages on Watling Street, Moat Lane, Park Street and nearby streets, not rear gardens.
A typical Towcester deck is either a compact platform in the yard behind an old town house on or near Watling Street, or a seating deck in the rear garden of a suburban or Towcester South home. The work usually involves setting pads on firm ground, building a braced frame, laying a membrane with drainage suited to clay, and fixing boards.

Permissions and checks in Towcester
- 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 Towcester 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. West Northamptonshire Council: tree works
- Step 3We check the ground and the planning position at the free design visit and give you one fixed written price.
