We are about to do the side return on our 4-bed Victorian terrace house in London. We have the option to put in a downstairs loo (and our architect is pushing for this) but it would mean cutting into the size of the kitchen - it would still be "eat-in" but would be pretty cramped.
I would much rather have a bigger kitchen - we have two nice bathrooms with loos upstairs - but am worried about putting people off when we come to sell (which we will probably do in about 6-8 years' time).
If you were buying, how important would a downstairs loo be for you?
