Ouch! £25,000 seems a very small budget for any size of extension Sophia, even at the lower prices we have here in N. Ireland. Especially as that presumably has to include VAT (so a pre-VAT budget of £21,000). It looks like an internal reconfiguration is going to be the answer and could give you a really great space and a decent chunk of money left over for some nice sympathetic finishes. Love the 1930's houses, they tend to be well proportioned compared to modern standards. Best of luck with your plans :)

I agree with 9yards, I don’t think you can do an extension within your budget.

If you move the kitchen to the dining room and have an island with stools……I was wondering if you could keep the fireplace and open the walls either side might be cheaper. you could have a pantry to the left of the fireplace and keep the right side open for a breakfast nook with the two windowsat the garden end of the current kitchen…. a small utility, for now by the WC whilst you save for a full width extension?
