Mulling over an initial idea to convert my mother-in-law's 1930s 3 bedroom semi to a downstairs flat for her, and an upstairs 1 bedroom flat she can rent out c/w her garage for some extra income.
She already has a downstairs loo in what was the coal house under the stairs, and is happy with a shower room rather than a bath. So my idea is when you come in through the front door, the hall is partitioned off so that is the access for upstairs ONLY. What is left of her hall the other side of the partition forms a shower room adjacent to the understairs loo. Upstairs, the layout is retained as-is, except the smaller of the three bedrooms becomes a kitchenette.
Now this is all fine in theory, but wondering if anyone has any practical experience of any pitfalls such as:
Does it need planning permission? Do building regs stipulate extra noise insulation would be required or that the wiring etc. would need to meet later standards etc. etc.
Just to confirm, I'd be looking to do the changes in such a way that they could be reverted back at a later date when the property was sold.
TIA, Midge
