My son moved into an apartment for college. Understandably, it had limited space, so he wanted a bed with storage space underneath. Nothing like that was readily available at IKEA. So we built our own. Plans are downloadable below.
Assuming that the lumber yard or hardware store can cut the lumber to size, these are the minimal tools needed to construct the bed. A person of skill will be able to do a good job with just the above.
Drill, preferably electric
Drill guide, Drill press
1/2” wrench of some type
Ratcheting socket wrench
Sand and apply coats of polyurethane finish
The whole thing just screws together in a straightforward manner. The only detail that merits mention is how to do the countersunk holes.
