When I began Foursome Season 4, all I was told is that the season will be epic and that I’d need to build a treehouse. This magical treehouse had to be normal on the outside and massive on the inside. The smallest details in this set have become my favorite things about it – the worn wood dutch door, 80s inspired toys, hand made kids crafts, leaves, dust and spider webs. This space is rather special. See if you can spot the trap door and the James Bond style rotating bookshelf.
