Hi guys,
Me again with another question on my latest project. I know there are other similar questions, but i havent found an answer yet.
In case you havent seen my other posts, i want to build a large shed/out building in the garden within permitted dev.
Please see the picture attached.
Basically, the out building will cover the entire green, an area of 30m2. The walls will be pretty much where the current brown edging is, but obviously it will be a square room. Im thinking single skin block with supporting piers. Each wall will be roughly 5.4m long. 2.5m overall height. Likely a cement fibre roof.
The room will be a golf simulator room, so very little live load.
As you can see, there are trees and bushes literally touching the edges, especially the big one to the right. These will all be ripped out, to create access around the perimeter of the building, however im reading that the type of foundation required will be determined by the trees and soil type.
Ive read that typically outbuildings use a concrete slab rather than trench footings. The red garage you can see in the picture is also built on a 100mm slab. However, ive also read that the presence of the trees, even when ripped out, could mean deeper foundations.
The big brown thing at the back of the garden is supported by a 150mm timber post at each side, i dug these 800mm down and postcreted them in. From memory, the soil was sandy.
How do i determine what type of foundations i need?
Will a 100mm concrete slab suffice considering it is single story, single skin, with very little live load?
Or will i need to go deeper trench foundations?
Ive done foundations in the past but ive just followed the orders of the builder, ive never had to do the working out for myself.
Thanks
