I "could" agree, except, for the most part, re-introducing 19th century conversions in reproduction form, isn't real cost effective. Takes a lot of investment to make 'em the way they use to. The potential market isn't large enough to amortize that huge investment.
"One Off" cottage production isn't real cost effective either. Trust me, true to form conversions are NOT inexpensive to build. Bring yer Broker you betcha.
