I want to build a 4m x 5m raised platform for my kids fort. It will be 2m high. I have a few questions:
It is OK to attach the posts at the corners or will I need more in the middle?
What do I attach the frame to the posts with?
How far apart should I place the floor joists?
What do I attach the floor joists with?
With the floor boards do I need some space between them?
Thank you. I probably will have more questions.
