Odd, I've seen some houses where the outer bricks do not appear to be supported by the foundations. I can't find an example now, but if you look at the bit ringed in red, some houses have the wall overhanging here by about 5 inches.
That's not brickwork, it's painted cement render by the looks of things.

A bellcast per chance?

Gravity and friction.

Oh I see. I assume this is to insulate single brick houses where cavity wall insulation is not possible?
Except that in the photo anyway, if you notice, exactly the same finish has been applied to the low walls of the gardens/yards at the back of the houses. The walls that the honeysuckle is poking over

But this house isn't the one I'm talking about, I said above I couldn't find a photo of one.
Oh, I didn't know there were double brick without cavity walls.
This house is. Built 1911.
To make it stronger or better insulated?
When I was involved in building things:-
Half brick wall = 4" thick, roughly. Stretcher bond, used mainly for cavity wall skins or really cheap and nasty garden walls. Originally, both skins of a cavity wall would be brick, later on, they started using concrete blocks (And later still, insulating breeze blocks) as the inner skin. The skins tied together with butterfly ties made of galvanised wire or twisted strips of galvanised steel every couple of feet or so in both directions. Sometimes used in cheap terraces from the Victorian and earlier times as party walls. Some *very* cheap and nasty Victorian terraces had these as front and rear walls, too, but most of these have either been demolished or fallen down by now. The rest are quite probably listed now.
Single or one brick wall = Nominally 9" thick (2 stretchers plus a mortar joint, or the length of a brick). Common as external walls on old houses and as new garden and low retaining walls. Normally either Flemish bond (Alternating headers and stretchers in the same course) or English bond (Alternating courses of headers and stretchers.) The corresponding Flemish and English garden wall bonds have either 3 or 5 stretchers between headers and aren't quite as strong. Many other bonds are possible, and many decorative features can be built in for minimal extra cost by a good brickie.
Brick and a half, or 1 1/2 brick wall = 13 1/2" thick, built with two headers and a stretcher at every position in the wall. Warehouse ground floor walls, supporting heavier loads than a 9" all can take or retaining walls if they're not *too* tall.
All can be reinforced, and the thicker structures built using engineering bricks such as the Staffordshire blue bricks and a strong mortar are extremely strong.
If there's no picture, it doesn't exist.
Um, that *is* a single-brick wall, although it may not be what Uncle Peter was thinking of.
(Whereas a cavity wall is normally a pair of separated half-brick walls.)
Well in that case, maybe you'd have been better off posting a picture of a hippopotomus or a helicopter. Both also start with an "h", are also totally irrelevant to the matter in hand, but would at least have the advantage of not giving rise to possible misunderstandings

I didn't feel like photographing someone's house. It's not got a view from the street, so it's not on streetmap.
I guess a single halfbrick would fall over.
I clearly noted it wasn't what was in the picture, so I don't see why people misunderstood. The point of the picture was to show the part I'd seen the overhang on.
