In my Junior year of High School, my school expanded into another building and came upon an unused storage room. A friend (pictured above laying on the table to check level) and I, who were both in the robotics team, proposed to build out a maker space for the team and for other projects in the High School.
We mocked up a design for the space, sourced materials (Home Depot and Lowes combined have everything under the sun you might need for a maker space) and build the tables you see in the pictures above. We also put up peg boards, and organized the space.
This was the second maker space I had built (see Fiore Montessori maker space build), and with a different set of constraints, (primarily electronics and smaller scale fabrication, think 3D printers) we designed primarily for open table space and collaboration.
