A house in the US that's still standing from the period 1870 to 1950 probably: - is balloon-framed - has zero insulation - might have knob and tube wiring kicking around - probably has a dirt basement - will be an absolute bitch to bring up to modern building codes if you want to do anything to it. - has coats and coats of lead paint - has asbestos everywhere
