Hi David the british weather doesn't bother me to much my WORK workshop is of 60's industrial concrete construction colder in the winter than air temp hotter in the summer than air temp , great for losing weight in the summer but you put it all back on in the winter
. Home workshop is on the side of my house plumbed a rad in there so nice and warm in the winter , nw facing so gets very little sun in the summer so stay's pretty cool.
