We're considering a single-storey rear extension + reconfig of other parts of the ground floor, which may give us an option for a (very modest) utility / laundry room space. It'll be big enough to house a separate washing machine and a tumble dryer on the floor level, but if they're stacked, we can have a bit more storage and add a utility sink. I've always wanted to banish washing/drying machines away from the kitchen and it's the first time I may be able to do so, which is very exciting
But I'd be grateful for a bit of advice. Would you rather have (a) a modes storage upgrade + a utility sink but stacked appliances or (b) floor-level washing machine and tumble dryer but slightly more modest storage and no utility sink?
