This book is about the building type that combines dwelling and workplace. It exists in every country and culture across the world in both vernacular and elite architectural traditions. Old but neglected, it is distinct according to culture and often hidden, disguised as house, shop, workshop or studio. These buildings range from the White House to the Mumbai ‘hutment’ where President and slum-dwelling handbag-maker respectively live and work with their families. In the UK, such buildings commonly include the vicarage, the pub, shop or funeral parlour with proprietor living above, the house with an ofﬁce in a spare bedroom or shed at the bottom of the garden, the artist’s studio-house and the live/work unit. This building type is important today because people all over the world increasingly work from home or live at their workplace.
