345G: “A place…” book for a Brit (Solved!)

I am in desperate search of a book for my dear British friend. She grew up in Suffolk, England, born in 1958, and remembers a book she used to pour over as a girl:
Possible title: A Place of Your Own
Contents: pictures and descriptions of homes, rooms, treehouses and places where children (and maybe young adults) escape to be kids
Publication Dates: at least published by 1972
Location: read in Suffolk, England

342I: Children playing in a tree


My brother and I have been searching for a picture book that we were particularly fond of as children. I don’t remember the title but it would have been published in the late 60’s or early 70’s. The story is about a boy (possibly named Keith) who has his father help him built a fort in a large tree in his back yard. Some neighbor children come by to play, and they end up adding their own structures to the tree. I remember one of the friends puts a big wash tub up in the tree and pretends to be an astronaut in a ship. Some girls bring their dolls up in the tree and make a tent with a blanket or some kind of hammock. There’s also a plank that they stand on that is supposed to be a raft? Maybe one of the kids was a pirate? Not sure, but before you know it, all the neighborhood children are playing in the tree. I can still see the illustrations in my mind’s eye and and would recognize it if I saw it. Thanks!

293D: Friendship in a treehouse

I would be so grateful if you could find my favorite chapter book as a child! It’s about a friendship between two girls, perhaps a summertime friendship. They spend time in a tree house together. The paperback cover painting was in browns and greens of the girls in the tree house. Likely, I bought it through Scholastic Books when they had those mini-catalogs sent to schools. It came out in paper sometime in the mid 1960s.
