I've got the big utility room/laundry room/junk room some of you want, the glory hole I can just shut the door on. It's our cellar. We have the washing machine, tumble dryer, big freezer down there, plus a sink, the ironing board, coat rack, shoe storage, vacs and lawnmowers and more plastic boxes and shelves full of junk than you could shake a stick at. And of course my wine rack.
My long term project is to clear it out to be the playroom it was when our DC were young. At the current rate of progress, the DGS will be at Uni by the time it's ready for them (the eldest has just turned 5).
