We build concrete bases across Northampton and its outskirts, about 25 minutes from our base in Higham Ferrers. That ranges from a shed base at the end of a long terraced garden, reached only by the rear alley, to a garden room or hot tub pad on one of the newer estates.
Much of Northampton sits on clay, which moves as it wets and dries. So every base is dug to firm ground and built on 100mm of compacted MOT Type 1 with a damp-proof membrane, with 150mm of concrete, or 200mm reinforced for heavier buildings.
Areas we cover: Northampton, Duston, Kingsthorpe, Abington, Weston Favell, Moulton, Wootton, Upton and Overstone
Northampton is covered by West Northamptonshire Council, not North Northants like the rest of our area. Its many conservation areas and listed buildings have extra rules for garden buildings, which we check for you.
Heavy clay swells in wet weather and shrinks in dry spells. A properly compacted sub-base and membrane under the concrete keep your base stable and your building’s floor dry.
Many terraced gardens can only be reached by a rear alley or jitty. We barrow concrete in or pump it over longer distances, so nothing needs to come through your house.
Newer estates often have compact gardens and covenants that limit outbuildings or hot tubs. It’s worth checking your deeds before you order a garden building.

Yes. We barrow the materials in through the alley or pump the concrete over, so nothing comes through your house.
A properly built base copes well. We dig to firm ground and lay a compacted sub-base and membrane, which is what keeps a slab stable on clay.
