Damp proofing a summerhouse

Hi All,

I am planning to build a summerhouse in my garden on the foundation of my old garage which I took down at the end of last summer. The foundation itself is concrete and I would say that it is structurally solid and suitable for the project but I am concerned about damp proofing. I wouldn’t think that there would be any damp proofing under this type of foundation being a garage initially.

Am I right in thinking that I could just lay out a damp proof membrane over the foundation and construct a treated timer floor frame (50x150 joists) on top of this? If so how do I fix the frame to the floor without making a hole on the damp proof membrane?

I would be grateful for any advice and guidance with this issue.

Kind Regards,
