Architect Gurmeet Sian has built a lovely garden shed in London, with bookshelves designed between the studs.
Built to a limited budget and timescale, the simple aesthetic of the materials is celebrated to create a functional and warm urban haven. Oak framed full-height doors are completely retractable and allow for a clear view of the garden. A library, situated within the structural members, maximises the usable floor area, and a ‘hidden’ rooflight at the rear of the space playfully frames an unexpected glimpse of the sky.
Lots of people have put shelves between studs in uninsulated spaces, but usually it is more random. (I did it here) This turns bookshelves into architecture.
