That's a lovely interest! Here are a few gift ideas based on that:

1. Book on treehouse building: You can gift him a book that teaches the art of building a treehouse. He might enjoy learning new ideas and techniques on this subject.

2. Treehouse construction kit: You can gift him a treehouse construction kit that includes various materials for building a miniature treehouse. This could be a fun activity for him.

3. Customized treehouse shirt: You can get him a shirt that features a treehouse design. You can further personalize it by adding his name or initials.

4. Treehouse experience: If there are any treehouse resorts or treehouse retreats in your area, surprise him with a booking for a night stay or a small vacation.

5. Personalized miniature treehouse: You can have a miniature treehouse built especially for him and personalize it with his name on a plaque. This can be a unique and meaningful gift for him to display on a shelf or desk.

Or you can get him a star map with the date when he was born.
