Does the ground under my garden change the price?

It can, which is why we never quote a base before seeing it. Bedfordshire’s ground varies more than most counties. The Marston Vale is heavy Oxford Clay, the same clay the Stewartby brickworks were built on, and it swells and shrinks through the year. The Greensand Ridge running through Woburn, Ampthill and Sandy gives free draining sand. Head south towards Dunstable and you are onto chalk. Three soils, three different bases.
