Block and beam floor in a garage?
Yup. I always wondered why both the garage and house were on a suspended floor, and its only when going through planning for the garage rebuild that its due to "shrinking clay", whatever the hell that is. Google turns up a load of conflicting info as to what it is.
Whatever, planning would not allow a solid floor for the garage.
Very odd, for a few reasons.
1) Planning dont have a clue about anything structural, that is a building control job (guessing a full plans submission so its pre-approved and the builder can ignore it as they tend to

).
2) A properly constructed concrete floor bears on both the ground underneath and the foundations.
It quite usual to have a house with BnB build but a garage has much greater point loads, hence my surprise (
checking the suppliers sites it seems to be possible although its recommended to use a stronger beam at circa 170mm wide and it must have a steel reinforced screed on top......so get your tape measure out!)
