I'm designing a shed (16'x24') for a wooded, slightly sloped backyard.
Restrictive covenants call for a "masonry foundation" for sheds.
I had originally intended to pour a continuous slab/stem wall for the
foundation, but I'm realizing I would have to remove a lot of trees to
do it (i.e. the site and a good 10 feet all the way around it to get
rid of the tree roots).
I was thinking of doing a cantilevered foundation using sonotube piers
and beams instead (no more than 10-12" overhang all the way around).
I'm thinking this would save on concrete and I wouldn't have to remove
as many trees. I could then skirt the foundation with some type of
non-structural panel, landscape bricks, etc. to give the appearance of
a masonry foundation (I'm pretty sure the neighborhood would be OK with
this as there is already an existing shed on plain sonobube piers).
I wouldn't cantilever more than about 10-12" - just enough space to put
something underneath the edges.
Is this a bad idea? What would you recommend skirting it with?
