We're looking at buying a property which would need renovation of pretty much the entire interior. The original building was built around 1870 (afaik), and later extended. There is a damp issue (see other post), no central heating, and the entire interior is rather old. Furthermore, there is a separate building labeled "barn" which we'd like to refurbish as a home office.
So, our list:
Resolve dampness in 150 year old building (sustainably? £1,000
Install central / underfloor heating: £2,500
Rewiring: £2,500
Replace all floors (probably with stone and/or wood): £3,000
Replace all windows and doors: £4,000
Replace staircase: £1,000
Replace all wood panel walls: £2,000
Reopen fireplace living room: £800
Put in new kitchen: £5,000
Put in new bathroom: £2,000
Finish "barn" to be used as office space (additional window, redo bathroom, change sink, finish walls, ceiling, floor): £8,000
The price estimates are taken from https://www.homebuilding.co.uk/renovation-assessing-the-potential/, and I personally find many of them ridiculously low. However, having absolutely no experience with house building / renovation, who am I to judge. From the above, I get the feeling with a budget of about £50,000 we might be ok. Does that seem rather low, high, or reasonable?
