Build the main wall system. The best way to attach into the 4×4 posts is with a Kreg Jig, hiding pocket holes on underside.
Next, build the 2×4 bed support. We made ours using the self tapping wood screws (2-3/4″ length but similar lengths would work just fine). Make sure this area is very square. Then attach the two pieces to the walls in the room and together using the 2-3/4″ screws. You will need longer lag screws to attach 4x4s to the wall.
Use a level to attach wall cleats to studs in the wall using the 2-3/4″ screws.
The only thing I would change on this loft bed system is the ladder. There are two things I did not like about how we did ours – 1. Iron pipe only comes threaded in certain lengths. So we had to cut iron pipe and weld to fitting to get the widths to work out just right. 2. With the span in our pipes, the pipes will sag when heavier people climb the ladder. So I suggest and improvement to my original design by adding 2×4 blocking inside the framing, spaced to fit your iron pipe fittings. This will solve the two issues we have.
I decided to use the 2x8s to support the mattress because it creates a nice sized cavity for drawers. 2×4 or 2×6 framing would have been fine too if you are not doing the drawers. If doing drawers take extra care to make sure the boards are attached square so you don’t have a cockeyed drawer that doesn’t slide right.
We used leftover 1×6 tongue and groove from the wall paneling to cover the back of the “wall” but any material will do – beadboard, paneling, plywood – your choice. It’s nice that this area is less than a full sheet of plywood. Just cut and attach with nails and glue.
We used 2×6 tongue and groove for the upstairs loft. You could probably get away with 1x material, but not sure if I would recommend it with the span over the doorway being so close to 36″. Another option is 3/4″ plywood, then top with 3/4″ hardwood flooring running the opposite direction.
Drawers should always be built to fit openings and drawer slides. The picture shows the perfect situation. For the shoe tilt out drawers I just used 1x3s to box out an area, and scrap 1/4″ plywood on the back, all attached to the door (see next step).
Attach drawer faces and doors. There should be an 1/8″ gap on all sides of the doors/drawers when installed properly.
For the bed slats, I used a full length board (front edge painted) for the first slat, then burned up any 3/4″ material for the remaining slats, splicing joints over the 2×8 framing.
I hinged a piece of 3/4″ plywood over the opening in the front. We cut a circle out in the middle to act as a handle.
Store bought black iron pipe is an easy railing (though not code approved so please be reasonable and safe here) and ladder.
