Composite decking in Bow Brickhill typically costs £200–£250 per m² supplied and fitted and softwood timber £110–£140 per m²; a 15–20m² composite deck is usually £3,000–£5,000, and raised decks with balustrades and steps cost more. On the village's sloping plots, the key question is height: a deck over 30cm above the ground needs planning permission, so we design the levels around that.

Composite & timber decking in Bow Brickhill

Composite & timber decking in Bow Brickhill

Bow Brickhill is a small village of around 620 people at the foot of the Greensand ridge, with All Saints church on the steep wooded hillside above and a mix of older cottages and individual detached houses on sloping plots. A slope is exactly where decking earns its keep. It gives a flat, usable area off the back of the house without the cost and disruption of building retaining walls and bringing in fill, and the space beneath the frame lets water running down the hill carry on past.

On a Bow Brickhill slope, the height of the frame drives the price as much as the area. The base guide is £200–£250 per m² for composite supplied and fitted and £110–£140 per m² for softwood, and a 15–20m² composite deck on fairly level ground is usually £3,000–£5,000. Where the low edge rises well off the ground, the deck needs balustrades and steps, and raised decks cost more. We visit for free, take levels across the garden and put a fixed price in writing.

Bow Brickhill specifically

What makes Bow Brickhill different

The village sits on Oxford Clay at the bottom with the sandy Greensand rising steeply behind, so the ground changes from slow-draining clay to free-draining sand within a short walk. Slopes push run-off down the garden, and a deck built across the fall needs that water to pass beneath it rather than collecting at the posts on the low side. Bow Brickhill has no conservation area, so normal householder permitted development applies unless a planning condition on your property says otherwise.

A typical Bow Brickhill deck runs out from the back of a detached house or cottage onto a garden that falls away or rises behind. The work usually involves taking levels, setting posts of different heights on firm ground, building a braced frame to give one flat surface, adding steps down to the garden and leaving a clear path for run-off beneath.

“Milton Keynes Driveways & Landscaping have just finished our full garden makeover in Milton Keynes. We had a porcelain patio, composite decking and raised sleeper beds. They arrived on time, kept my home clean and the garden looks terrific. They are coming back to do our block paved driveway soon.”

Questions

Composite & timber decking in Bow Brickhill: questions

How much does a deck cost in Bow Brickhill?
In Bow Brickhill, composite decking is typically £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. On sloping plots, raised sections with balustrades and steps cost more. The fixed price follows our free visit.
Do I need planning permission for a deck on a sloping Bow Brickhill garden?
There is no conservation area here, so normal rules apply: a rear deck is permitted development if no part is more than 30cm above the ground and it covers no more than half the garden with other outbuildings. On a slope, the low side can easily exceed 30cm, and then planning permission is needed.
Can a split-level deck avoid the need for planning?
Sometimes. Stepping the deck down the slope in two or more levels can keep each part closer to the ground. Whether it stays within 30cm everywhere depends on your levels, which we measure on the visit.
Water runs down our garden after heavy rain. Will it damage the deck?
Not if it is planned for. We leave space beneath the frame for run-off to pass, set posts on firm ground, and lay a membrane so water flows under the deck rather than pooling around the supports.
