I’m considering buying a 1600sq ft bungalow. It has amazing views and overlooks Chiltern Hills AONB. However it was owned by an elderly person who has deceased and hasn’t kept the house in great condition. We currently don’t know enough about the foundations (we’d obviously do a survey), but the house is very likely to be sold quickly and we’d like to get a rough sense of how much more money will be required. 1. Does anyone know how much a loft conversion costs? It is easy to do, and could you live in your house whilst work was being done? I’ve seen some articles saying 50-70k for a bedroom or two with one en suite, but wanted to know if this is realistic. 2. How much does it cost to build a decent spec bathroom and kitchen? 3. The other option would be to knock the bungalow down and build a 2.5k sq ft house (the neighbours have done this, and we’d essentially want to copy their design). This would allow us to alter the pitch of the roof and have a much bigger space. Again, does anyone know ballpark how much work like this would cost, if we were going medium-high spec? I’m an absolute novice at building work and there is lots of contradictory advice online, so any advice (even if just a range) would be gratefully received.
