In the house we renovated there was a large cavity under the staircase that I filled with a storage cupboard.
The space wouldn’t be used because it was narrow and deep, so I drew up some plans and built a giant cupboard into the space under the stairs. It had two rear facing doors with tall cupboards and three large doors that opened out to reveal shelves.
The end cupboard was great for ironing boards and tall items. We put boxes into the shelves to add even more storage room. The first cupboard was quite small, but was enough to house the wi-fi router and board games.
The cupboard was built to fit into the space as much as possible, but still to have room to display items on the top. It was painted the same colour as the wall to ensure it blended in with the room. Carpet was then laid around the cupboard and it became a hidden feature of the room.
It was made out of very thick mdf boards and then painted a dark chocolate brown in the inside, but the same colour as the wall on the outside.
Overall it gave the small townhouse a new level storage that it previously lacked while utilising the wasted space that was currently there.
Here are some pictures of the finished product.
