If you wish. the door in the passage can be closed, allowing Bedrooms 3 and 4 to be en suite with the shower room. This can be ideal for a couple with 2 children, or alternatively , if Bedroom 4 is not needed it can be used as a dressing room for Bedroom 3 , with en suite shower room. The bathroom then becomes private to Bedroom 2, just across the passage.
Alternatively, for more flexible accommodation, leave the passage door open, allowing three bedrooms to share the shower room and bathroom
