currently building an extension which will include an integral garage. the site has multiple levels and to find a compromise has been difficult. however, building regs state that as long as i get at least 100mm drop from the utility finished floor level to the garage floor finished level then that is all that is required.
I would love to raise my garage floor to the minimum of 100mm but in doing so i would bring the floor level up to what is currently the external wall DPC. would i be creating any issues here or should i drop it about 30mm below which would be my lowest i can go.
