Hi there
Basically I have got a single garage in my garden at the moment that leaks and is damp and made from asbestos so getting that taken care of and then wanting to build something a little smaller for a workshop. There are two trees (birch) nearby that are about 15m high so wondering how deep and wide i should dig the foundations. Going to be building it as a cavity wall with brick outer and block inner with insulation and a flat (warm roof) with 100mm celetex wedged between ply. For those thinking it is overkill for a workshop I need it to be warm as I will be also using it to smoke in as not allowed to in the house anymore!
What i need to know is then how deep/wide should the foundations be. What concrete mix to use for the foundations and would i need any root barriers?
Also wondering what the pros cons of using thermalite blocks for the inner wall or whether i should just use 3.5 or 7n concrete blocks.
Also what would be best to use for the cavity insulation?
(additional the trees are about 3m away)
thanks dudes
