Advice on a fixer-upper please? (floor plan inc)

[medianewbie]

I am looking at a property in rural Scotland. In a terraced row. 1880s stone & slate roof. Very dilapidated. Layout is 2 houses & shop/workshop/yard. Agent says could be made into 3 houses, Air B&B, make oodles of cash. No. I know the area well. It would cost a fortune & take years to re-coup, if ever. I'd like to keep it as one house (there is access right through ground floor) & renovate the outbuilding as a family area.
Probs are: no gas, no heating, no damp proofing, leaky roof, no downstairs w/c, 1 tiny bathroom with no ventilation. 1 waste/sewage point (marked with a * on plan)

Can anyone advise re extra ground floor w/c, poss moving bathroom to smallest bedroom, extra shower 'pods' in 2 larger bedrooms please? Thanks.

I assume it isn't listed?
In terms of a downstairs loo maybe section off part of the kitchen to make a utility and loo? It's difficult to tell where the widows are and whether that would work.

Lack of damp proof course isn't an issue but you need to make sure the walls stay breathable so use lime plaster rather than modern stuff.

It won't be easy to move a bathroom to the back of the house unless there is already drainage that side for the kitchen? You would need to dig a trench round the outside of the house and lay a new waste pipe. Unless you have very high ceiling and can afford to loae a bit or extremely deep joists.

What are you going to do for heating? Air source heat pump? I would advise going for underfloor heating upstairs and down if you can afford it. It works well will a heat pump as the water temperature is lower than normal heating.

Whatever you do, sounds like an expensive project. I would be thinking at least £100,000 maybe more.

Sounds like a money pit. What’s the attraction?

@HellsBalls it's cheap, it's big, it's private. I know the village. It's ideal.

It also has a closing date of Tues @ 12 so I think local builders are after it too.

@Geneticsbunny thank you. Some things I'd thought of you've reiterated which is encouraging. Some points I hadn't which is very helpful indeed x
