The bookshelf stair is still one of my favourite home improvements ever, but this bookshelf apartment by Rintala Eggertsson bests it by converting your whole 6000-book library into one intimate living space. Take the video tour.
Here are some great photos by Pasi Aalto:
Sadly, the Ark is not a real apartment, but a structure for the Small Spaces exhibition at the Victoria & Albert Museum in London. That's really too bad, because I just want to live surrounded by 6000 books, and then spend my days reading the 120,000 volumes of my iPad.
If you are in London, you can see it until August 30.
