JOAT pretty well summed it up. Also, Google for a little inspiration
and if you look close at many of the pics you can estimate distances for
certain objects. I'd suggest you build it to adult height so when the
kids outgrow it, you can use it for storage or as a shop. Take a trip
by several of the larger stores like HD & Lowes etc and see what they
put together for these in the spring, then build yours strongerG.

Does anyone kow where I could get guidlines for building a kids playhouse?
Things like railing height, spindle spacing, ceiling height, things like
that. I'm building a 2 story structure with a bridge to a "look-out post"
with ladders, a rock wall, a slide and a pole to slide down (not sure about
the pole yet). Any info will be helpful.

Thanks
