Library built into a staircase

The stairs going up to the attic room of a Victorian row house in London have been fitted with books that line each riser and wrap around the edges. As someone who lives in small places with lots of books (and no matter what I do, no matter how ruthless I am, I always seem to have lots more books than I have room for) this kind of thing is sheer aspirational porn for me.

The flat occupies part of the shared top floor of an existing Victorian mansion block. Our proposal extended the flat into the unused loft space above, creating a new bedroom level and increasing the floor area of the flat by approximately one third. We created a 'secret' staircase, hidden from the main reception room, to access a new loft bedroom lit by roof lights. Limited by space, we melded the idea of a staircase with our client's desire for a library to form a 'library staircase' in which English oak stair treads and shelves are both completely lined with books. With a skylight above lighting the staircase, it becomes the perfect place to stop and browse a tome. The stair structure was designed as an upside down 'sedan chair' structure (with Rodrigues Associates, Structural Engineers, London) that carries the whole weight of the stair and books back to the main structural walls of the building. It dangles from the upper floor thereby avoiding any complicated neighbour issues with the floors below.
