You can build a playhouse as high as you want. However, you should always consult with a professional to ensure that it is safe.

You can build a playhouse as high as you want as long as you have the proper permits and follow all zoning regulations. consult with your local municipality to find out what zoning regulations are in place for building a structure of that height. In most cases, you will need a permit to build something that tall, and there may be restrictions on the type of material that can be used for the structure.
