Playhouse w paredes de escalada

I am looking to build an outdoor, free standing, enclosed playhouse (keeps out the rain), where two adjacent interior walls will be dedicated climbing walls. The overall objective is to provide years of fun for two little girls.

I'd like the wall height to approximate ten feet to facilitate the climbing aspect. The interior space must be 100 sq feet or less and one story to avoid permitting requirements.

On the two non-climbing walls I'd like to let in A LOT of natural light and also have screening capabilities for fresh air and no bugs.

The playhouse will be for two girls the oldest of which is three, so another must have includes an attached swing (room for 2 swings). Other ideas I thinking about to keep the girls busy outside are an attached slide or climbing net, but they are not must haves.

I like contemporary eclectic styles, and color, but not must haves.

I am not certain of my budget, but something around $5,000 seems to be a reasonable goal at this time.

Please identify the major materials that will be required (e.g., for the exterior). For the foundation, I will use pressure treated 6 by 6 studs from Lowes, unless there is a better idea. I would like to avoid pouring concrete.

I am thinking of buying the climbing walls from Elevate Climbing Walls, so designing the climbing walls themselves is not necessary.

As part of the selection criteria I will focus on (1) the design that has creative ideas, (2) the design that meets the most of my thoughts above, and (3) the design that is not extremely complicated to build or source.

Thank you!
