Hi,
I am planning to build a garden outbuilding. Essentially to be used as a large shed/storage area.
There used to be a concrete sectional garage on the site so there is an existing brick perimeter wall that this used to sit on, at ground level. The width of this foundation is 2.4m (8ft).
So I could very easily span this with say 2x6's. But I would like a 3m wide building.
I am thinking, therefore, of keeping the foundation as is, but placing 3m 2.x6's on it. So there would be a supported span of 2.4m and a cantilever of 0.6m.
Which I think would be fine if it was a simple deck on its own. But, the front wall of my outbuilding will be sitting on the extremity of the cantilevered part of the floor, not directly above the foundation brickwork. The wall will be 2x4's with OSB sheeting and cladding, and on this side incorporating a door and possibly window. The back wall will be the same size, but sitting on directly over the foundation brickwork.
Hopefully makes sense. Is it ok to do the cantilever like this?
