Thanks for the plans Ana!
I stuck to the design but changed the dimensions to suit the space and the boxes we intend to store. This made the shelves 7.5 feet high by 8.5 feet wide. The timber was supplied in 17’ lengths so this also meant very little wastage. The frame is composed of 2x4’s, the shelves are 4.5 x 1.5’s - as I wanted the shelves slightly shallower this meant I could get away with three boards for each shelf instead of 4 as on the plans.
For the short cross pieces I used woodglue and screws – to attach the long shelf pieces I just used screws. I predrilled holes in the first piece for each of the screws, but I didn’t drill a pilot hole in the next piece, the screws were self-tapping and didn’t need one.
The back wall is concrete block and I screwed each upright to the wall using wall plugs and screws. I’ve 2 young children and as the shelves are quite high I was afraid they might climb on them and tip them over otherwise. The attachment to the wall definitely makes the whole thing feel much sturdier – the structure is completely rigid.
The only real issue I encountered was that some of the boards were slightly twisted or warped – and I had to apply some force to keep everything square when I was gluing up. Overall I’m very happy with the end product, and found it reasonably easy to put together. Now its time to put the shelves to good use and start tidying up the garage!
