Wood floors: I was going to ask if were cold, but I guess not if you have underfloor heating! Not sure we're up for that. I love wood floors, though. If cost were no object (so I could just replace it or get someone in to sand down any problems as occurred). I'd have an interior decorator, though, if cost were no object. I have zero interest in home decour or improvement, otherwise.
Fibre: man said that 80:20 wool:synthetic was what we already have & have been happy with, and is good because 100% wool sheds like a furry cat (I already have 3 of them ).
I can't find the sodding carpet-flooring quote (sob). I think we need about 80m2 carpeted, though. I just estimated my fairly large lounge as about 29 m2 (does that seem plausible?). Plus 6 other rooms (effectively). The £3.1k quote includes fitting cost and not having to move most the furniture out (headache).
I was quoted £425 to have most the downstairs furniture & some boxes moved out & stored a mile away for a week & put back. Don't think would be cost effective, although I have an extremely heavy piano that has to be moved out & back by professionals (I'm hoping get that done for £80 or so).
They said carpet-fitting-only costs for our fairly large lounge, even with fitters having to move furniture, would only be £45.
