I designed and built this table for my great-grandson. I cut the legs from 2x4s, the top from 3/4-in. plywood and the shelf from 1/4-in. plywood. The trim and leg supports are cut from 1×4 pine. The Lego construction plates were purchased online from shop.lego.com. You can purchase a variety of these pieces; I used two plates for a road and two crossovers for parking spaces. There are nine plates total that measure 10 x 10-in. each.
I mounted the trim top edge the thickness of the construction plates above the tabletop. The construction plates then ﬁt snug to the trim, so they do not slide around. They can be easily removed and changed for different designs.
The unique feature of this table is the two trays built into the sides, which were done by simply extending the trim. The trays allow the builder to have the blocks and other pieces close to the work surface.
Most DIYers that I know have enough scrap material laying around to make a project like this, that is one reason for the painted ﬁnish instead of a stain. — Victor Paolino
