This is a perfect combo of my two favorite ideas for that space under the stairs leading to the basement. A reading nook AND book storage and shelves . assuming that there is enough space for this there.
close up play room closet behind, utility room. open it like this to make laundry closet at the back door. Enclose the water heater. use space where w/d are now at right of door as a little built in seat for bags & coat hooks over it.
In a home short on storage, builder Todd Best worked hard to provide his client with plenty of cabinet space. This custom sliding storage unit was built into an area of the master bathroom that is normally wasted space.
