That is quite the sandbox to play in!
Ricky, you should invite Brian Wilson over!

What purpose does all this sand serve? In the UK houses are built very differently.
It's just used as fill. Something to pour the concrete pad on. I haven't seen anyone use sand before though. I've seen crushed concrete and/or stone. It all has to be compacted to firm it up. Ricky, was sand used because it's cheaper and there is so much needed? Is it superior? Couldn't you just have left it as a crawlspace and laid joists across the foundation walls, like a basement kinda?

Indeed - sand as fill compacts the best. And has price advantage over crushed concrete and gravel - especially since I am filling cavities upwards of 48 inches in height. That last 2-3 inches will have a gravel base.
As far as having a crawlspace via raised floorjoists --a couple of comments: 1. half of this barn is actual garage ( for cars and tractors and such ) so that area could not be framed. Hence cement floor. 2. In Michigan - crawlspace poses problems for cold and humidity. The cost to meet energy code far exceeds the cost of fill and cement. Ricky dont like crawlspaces

Cement is best for placing subs on as well IMO

The house I’m in now is the first one I’ve owned with a crawlspace under the house. It’s not my favorite place to be, either, but it made several wiring jobs possible. There are SIX attic crawlspaces, including the three around and over my listening room.

My parents house has under floor and attic crawlspaces, and that allowed me to install a load of CAT 6 network cabling and completely rewire the mains electrics. My dad used them to install under floor heating downstairs and then I insulated below that, this in a house built in 1960.

By contrast my house was built in 1987 and has concrete floors downstairs. I can't do a damned thing, and the concrete floor is uninsulated (standard when it was built) hence I get cold feet in winter. I'll take the crawlspaces any day.

Install flooring with underneath heating? It's done here in the States. Not necessary where I live though.
Which reminds, I have some new CAT cable to run under the house. Nothing like a good low crawl in the dirt to spice up your day.

I only have 7'8" from concrete to ceiling downstairs, I really can't tolerate the loss of headroom that would be involved with heated flooring on top of the concrete. I have looked into it: electric heating would fit height wise but cost a fortune to run; circulating hot water wouldn't fit height wise.
