How about gifting your husband with a stay at a treehouse resort where he can fully immerse himself in his love of treehouse building? There are various treehouse resorts all over the world that provide unique and adventurous experiences for guests, such as Costa Rica Tree House Lodge, Chateau Dans Les Arbres in France, or Treehotel in Sweden. Alternatively, if you have the space in your backyard, you could put together a DIY treehouse building kit for your husband to work on throughout the year as a fun project. You could include building materials, a guidebook, and even some tools to help him create his own personalized treehouse. Another option is to sign him up for a treehouse building workshop or class where he can learn from experts and sharpen his skills even further.
Or you can get him a star map with the date of your anniversary.
