Some possible blueprints for a child's playhouse include a Gothic style, traditional and Wendy house designs. These playhouse blueprints are available at the Southern Pine, DIY Network and Buildeazy websites.
A typical blueprint is an American Gothic-style playhouse that is reminiscent of Victorian-era homes. The Southern Pine website has a free plan for this playhouse that is 35 square feet and has a front porch. However, it can be a hard DIY project for a beginner. The plan is downloadable and comes with blueprints, materials and tools lists and complete building instructions.
The DIY Network website has a plan for a traditional backyard playhouse. The site has a complete list of materials/tools and step-by-step instructions for this project that can take 2 days to finish.
Similarly, the Buildeazy site has elevation plans with explicit construction instructions for a Wendy house that has certain feminine features as well as a front porch. The dimensions of this playhouse are 78 inches in height, 92 inches in length, 48 inches in width and a front porch deck that is 28 inches in width.
