Need to extend concrete base raft/slab for new garage, the base will be going within 1.5m of a mature tree. The building is only timber (log cabin style) so will not be heavy but is 40m2 so need building regs. I emailed my local building regs people but they are not that helpful, have just said you may need suspended slab but how do i tell if i will or wont, do i have to make an application before they tell me? The slab will be 13"+ thick anyway and i'll be extending it by nearly 1000mm width so will need about 5m3 of concrete as it's 7m long. Can anyone refer me to specific sections of any of the building regs documents.
Thanks for any help
