I'm planning to build a wall to screen gas tanks and dustbins. An extension of the existing garage wall, which is built of rendered blocks.
8' long, 4'6"/5' high. The space available for the gas cylinders determines that there's only room for single thickness blocks.
Presumably 3.5/7N concrete blocks?
What foundations would such a wall require? It will be built right alongside an existing concrete path.
Also, how would I join it to the existing garage wall?
Single block wall

Or drill and plug some wall ties wants a 300mmx100mm deep concrete footing on good ground or a spread footing of block laid flat if good ground but the concrete is the way to go if you can.

Yep, i would go furfix, or anchor bolts. Just drill a 7mm hole and run the bolts in on an impact driver, quick, stainless and strong
As for the footing, building control would make you go 1m deep at 600mm wide if they had to dictate. I would go 450 deep, 450 wide if it were mine, assuming no big trees etc etc near by

It's only a 4 foot high single skin wall that's massively overkill, no bco involved
300x100 is overkill for that

Thank you very much, gentlemen.
Some further (naive) questions:
1. Whatever the width of the footing, is it OK that the blocks won't be laid in the centre of it, but next to the edge of the existing concrete path?
2. Anchor bolts - would I use them like dowels in woodwork? ie part into the existing wall, part set into the new
blocks, or like wall ties, ie set into the mortar joints?
3. The second part of the project will be to build a sandstone wall from an existing stone outbuilding towards the new wall, with a gate in the corner, so the two walls, made of different materials, won't actually meet.
The line of the proposed stone wall crosses another existing concrete path: in fact the path takes up nearly all of the length of the new wall since it comes in diagonally. Can I treat the path as a footing and just build on top of it?
