Sounds like something that requires an urgent trip to the GP for some sort of topical cream
.Sorry, I'll show myself out.

Very nice, doubt they'd do much here other than having me spinning around hanging onto the motor

When I lived in the Netherlands everything was built on piles...even tower blocks

I drilled a 24" hole thru clay, blue clay and then shale (had smoke coming from the hole) min. 48" deep, with an auger attachment (rented for $75 a day) onto my small skid loader.

What do you think they use here, then?

On my building I drilled 12-14" dia holes, and set 8" sonotubes with a re-bar cage & weld on bars on top. Qty (21) of them.
12"-14" dia. gave me wiggle room to accurately place the tube to the string lines, and then held up to grade with scrap wood screwed to the sides of the sonatube,
this left a space underneath where the concrete belled out.
"Screw Piles" is the term over here.
When you say small how small though. Rear access to allot of UK houses is only around 27in wide. It's why micro diggers are prevalent here.

6000 lb machine. 54" wide or so 48 hp.
Although Bobcat makes a 36" wide special just for backyards.
I'm surprised a small micro digger could not swing (and lift) the auger.
Did you consider xplosives ?...

I think a micro would spin around the auger if you tried drilling a hole that size.

"Think" or "Know for certain" ?
You wouldnt be able to find out as they don't make an auger set up big enough to find out.
Micro augers fit machines from 0.7t-2t and only go upto 300mm. 300mm will be maximum in ideal ground for a 2t machine so a true micro that will fit through a gate at <1t stands not a lot of chance of driving a >450mm auger
I built a steel framed building, dug 3ft long, 3ft wide, 3ft deep holes for the legs to be concreated into
get a bit further along building it and realised my forklift didn't go high enough to reach into the upstairs, I'd already welded my end plates onto the legs so instead of shortening the legs I dug the holes another 2ft deep
digging is much easier when you're young

Age is irrelevant with a digger! Shovels and spades are so last year

I guess it depends on ground conditions...if you are close to bedrock then you don't pile do you!
Netherlands is mostly sand...the piles were bloomin impressive for the bigger buildings...I seem to remember they're piling down 40m+...but could have got that totally wrong.

Most piling goes as deep as the soil samplers tell them, I put an extension on a mates factory and the piles for that went down a hell of a depth. Soil samplers found a heavy layer of peat at about fifteen metres down, piles had to go through that and into solid ground. Then formed a concrete ring beam on top of them.

Talking to a mini-piling guy once he said they do a blow count to judge if the pile friction is high enough. This was tiny piles about 6" diameter that the guy was hammering in with a tubular weight. He cut and welded a point on the first tube then welded on subsequent tubes and kept walloping them down until his blow count was high enough to stop.
Footings and specifically piles don't just rely on sitting on solid ground but the friction on the side of the footings. I think a 450mm square hole equates to about 600mm diameter hole. Bit more complicated than my maths allows for but I know it's why square footing are preferred by engineers in many circumstances where round would be alot easier
