As of June 2015, websites for Lowe's, DIY Network and Ace Hardware have free outdoor playhouse plans. All sites use photographs to illustrate certain steps of the building process.
Lowe's has printable plans for a playhouse with a double-hung door, installed windows and window boxes. The plans divide up work into seven days. The website lists the skill level needed to complete the project as Advanced.
The playhouse available at the DIY Network takes two days to build. The table of contents organizes the project into 29 steps and includes a video introduction. The design of the Ace Hardware playhouse allows adults and children to construct it together. The building has open windows and doorways.
