We are in the process of extending and can't decide whether to include a window in the utility room. The room measures 3m x 1.5m so we're quite restricted on space and obviously a window will take away storage space. The 3m external wall will have a washer & dryer stacked, a sink and a door with a glass panel at the top so will get some natural light. The window would need to go on this wall too. It will be used as a laundry room & dog room (wet smelly dog who swims every day!). Advice as to whether we need a window gratefully received.
