The bed was built in my shed, in 4 main parts. This allowed me to actually fit it through the door into the bedroom and also, the bed is far too heavy for one person to move when fully assembled. I started with the bookshelf, then build the ladder and foot end. Once they were complete, I made the base frame for the mattress, then the peg board backing.
Step 2: Bookshelf
I have used 35x300mm solid ply to build the bookshelf. It is very heavy, but also solid and strong. If this ply is not available, you could just as easily use pine or particleboard. For the backing, I used pegboard, as I had acquired a substantial quantity of this. again, you could use 3mm ply, MDF or something similar. I glued and also nailed the shelves in. Above the top shelf is a 90mm gap to allow an area for the bed rails to bolt to. The bed head is 10mm ply, which has been covered with soft filling and some material.
Step 3: Foot and ladder end
For this end I used 90x45 pine. I used fairly large size timber as I wanted to be sure that there was sufficient strength. Again, the timber is glued and also nailed, except the treads of the ladder, which are glued and also screwed for strength.
Step 4: Base frame
The base frame is made from 2 stringers of 90x35 pine, with 42x19 supports along the inside of each length. 90x19 pine planks were cut, glued and nailed between the stringers. at the head end, the planks were left off and I made a small insert to fit inside the top of the bookshelf, to allow for easier assembly.
