When you see the final design, do not flinch at the sight of its DIY look haha. So, using two blocks of wood, I cut the shape to be able to lock and screw them onto the door side and shelving wall side. This was to form my lock for the bottom half of the unit. As shown, a screw is the key to this lock. Nice, easy and simple.
I was wrong. I actually added three more needed features. So make sure you check back next week for the next post in this lovely DIY series =D Until then everyone.
