We had a utility room in our current house but, it wasn't large enough and was not fully isolated from the main kitchen space, so we removed it in a project to rebuild the kitchen. This meant integrating a number of appliances. I don't like integrated appliances though. They are more expensive and often compromised to fit into standard spaces.
Our new build will have a seperate utility room for things like the washing machine, tumble dryer, chest freezer, etc. It will also have a sink.
This room will have automated lighting based on detected occupancy and the twilight sensor.
This room will have automated air inlet and extraction controlled by a humidity sensor in the room. This will support its use as a drying room.
