The inside will be used as a play area here, but it will easily fit a single mattress for when he is old enough to have a friend over for a sleep over. I am designing bench seat futons at the moment.
I didn't start taking pictures until I was 3/4 of the way through the project. Kind of spaced it out to be honest. I will provide illustrations up to the point pictures were started.
I have added the sketchup file I used in the design phase of the project. Some measurements may be off a tiny bit within it.
If you think this project is deserving, please vote for it in any of the contests it is entered in.
Make it Real Challenge
I would love to win the Shopbot CNC. I could finally start my home business and produce many of the designs I have created on my computer.
A side note. Using the same basic design of this project, I am sure you could tweak some measurements and convert a boring old bunk bed frame into something great.
