Gunnebo och andra sommarnöjen från 1700-talet kring Göteborg by Lars Sjöberg and Staffan Johansson is a book mostly about Gunnebo, a late 18th century summer house near Göteborg. The book has plenty of information about the history of the building and the architecture and interior, accompanied by many photos and pictures of the original plans. At the back of the book there are a few shorter chapters about other 18th century summer houses in the Göteborg area.
I love this book and recommend it. The photos are gorgeous and there are many of them, and the text is interesting and fun to read. As far as I know this book is only available in Swedish.
(By the way, I just added a “buildings and interiors” category to the right.)
