William's 4x4 Playhouse

The Williams 4×4 Playhouse is a simple, affordable option that’s perfect for younger kids and smaller backyards. With its classic gable roof and open window design, it has the look of a traditional clubhouse while keeping the build easy and cost-effective. The compact 4×4 footprint makes for one of our smallest designs, and provides a great choice for tight spaces where a larger playhouse might not fit.

This plan focuses on practicality without sacrificing charm. It includes clear instructions and a full materials list, making it a good project for DIYers of all skill levels. The open layout allows for plenty of fresh air and visibility, so parents can keep an eye on playtime. If you’re looking for a no-frills, backyard-friendly playhouse that still feels special, the Williams 4×4 is a solid pick.
