How many bodies to you intend to sleep in there? Kids and adults? If little kids bunks might be possible.
Options:
1) what about 2X2X8 frame I think they are 7lbs, I will probably need 5, so 35 lbs. If this works, just embedded the lumber in the 3" foam of the side wall and glue, it will just be a load bearing wall to the roof and screwed to the floor. I should be able to do this. cost about $25 plus screws.
2) 1/2X4X8 plywood is 50 lbs. This will be hard to anchor to the floor walls and roof, maybe too advance for my skills. cost about $50 plus braces.
3) 3" foam board is 12 lbs, this will just be cut to shape, glue to foam, wood floor and have pmf covered. cost about $50 plus PMF cost so another $50?
There should be 2-3 adults and 2 kids (7 yr and 2 yr but they will grow up fast).
Picture to illustrate framing...
Thanks,
