Demonstrate this please. Without materials substitutions. Genuinely interested in the answers.
The cost of raw materials is very high as far as I know.
You can't get good hardwood, copper and so on without paying top dollar. Same goes for slate, trim.
I know that because I am actually attempting to build a tiny house in a traditional style for a little higher than 50k.
This would be a very valid comparison because it is;
1. Ignores cost of land. 2. Labour is free. 3. Doesn't ignore mod-cons.
I think the real difference is a normal person could have afforded the older house with a legal status!
