Re: How old is old?
Not sure, but the "new" house on the family farm back in northern Sweden is over 300 years old!
I think that architectural significance plays a big part in what is chosen. If there's a good life story behind the house, that helps. Also, they seem to like to show off as many trades as possible, and demonstrate a lot of new/different materials and techniques.
The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
