Fire pits & sunken seating in Milton Keynes
Fire pits and sunken seating for Milton Keynes gardens, built with the drainage that the city's slow-draining clay demands.
In Milton Keynes a built-in stone or brick fire pit typically costs £1,200–£2,000, and a fire pit with built-in seating from about £3,500. A full sunken seating area is priced per job. The key local issue is the clay: it drains slowly, so anything dug below lawn level needs a drain or outlet planned before the first spade goes in.

Fire pits & sunken seating in Milton Keynes
Milton Keynes was planned around its ground. The balancing lakes at Willen and Caldecotte exist because the Kellaways beds and Oxford Clay under most of the city hold water rather than letting it soak away. That matters the moment you dig a seating area into a lawn: you are creating the lowest point in the garden, and on clay the water will find it. We build fire pits set into the patio and sunken seating areas with retaining walls, built-in benches, steps and a drain at the bottom, so the space stays usable after a wet week.
Milton Keynes Driveways & Landscaping covers MK1 to MK15 and the old villages the city grew around, including Bradwell, Great Linford, Shenley Church End, Willen, Woughton on the Green and Loughton, and travel does not change the price. Every job starts with a free design visit. We look at where the fire can sit clear of fences, trees and the house, how deep the ground lets us go, and where the water from the bottom of the pit will go. You then get a fixed price in writing.
What makes Milton Keynes different
Clay that shrinks in summer and swells in winter is hard on retaining walls. We set the walls of a sunken area on proper footings with drainage behind them, so water pressure does not build up and push them out of line. A soakaway on its own rarely copes in this ground, so we size the drain at the low point for what the clay will actually take. Most grid-square estates sit well away from the Great Ouse and Ouzel flood plains, so surface water, not the river, is what we design against.
A typical Milton Keynes job is a rear garden behind a grid-square estate house: a lawn, a slab patio by the back door and neighbours close on both sides. Most people want a brick or stone fire pit set into a new patio, or a shallow sunken area with a bench on two sides, positioned well away from the fence line and finished to sit with the house brick.

Permissions and checks in Milton Keynes
- Step 1A fire pit or sunken seating area in a rear garden does not normally need planning permission. Keep fires a safe distance from fences, trees and buildings, and be considerate of neighbours: smoke can be a statutory nuisance. Listed buildings and the old village conservation areas have tighter rules, so we check your address before anything is designed. Planning Portal: outbuildings
- 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.
