Building a cupboard under the stairs

The problem with removing nearly every internal wall and cupboard and making the house totally open plan has meant that we are left with very little storage. Thinking cleverly about using every last little bit of space as well as building an under stair office we are squeezing in a small cupboard under the stairs. 

Well I say a small cupboard under the stairs, but it's not actually that small and can fit a James in there quite comfortably!
