5x3m block garage/shed.

[mattprince]

Hi all,

Going to be doing the footings for the 5x3m single block garage/shed soon. How deep will I need the footings to be? Going to be 7ft high at the front and 6ft high at the back. Single block. What's the best way to waterproof it, keep it damp free and also to soundproof it a bit?

It depends on the ground.

It's grass.

Was going to dig and do 2ft concrete footings .

By my calculations you need an approximate depth of 76.2 widths of the perpendicular sum of the height / weight variation.

It's grass.

Run over it with the Flymo then, set the blade on the low setting.

Ok thanks for all the help

Best depth - look at the ground conditions as you descend (past the grass) and see what it is saying at 1m deep.

Best sound insulation - build it as solid 215mm wall or cavity wall with an insulated tiled pitched roof, and a ceiling.

Best damp proof - build it as a standard (150mm up from ffl, DPM/DPC) cavity wall or 215mm solid. Poor mans' version would be single skin with a weathering material fixed externally. Put a roof on top.

Best thing is I've just been given nearly 2000 thermalite blocks for free. Nephew is in construction and got so many left over. Only need about 450 myself so going put the rest on Freecycle

Thermalites are fine for the inner skin, you'll need something a bit stronger for the outer.

Don't let the nephew order the concrete or roof tiles.
