When it's done, it will look something like this:
The entry and stairs are complicated. There are three flights that transition between four split levels. We realized that the actual construction will probably require a lot of 'adjustment' as its built so we wanted to come up with a design with a lot of flexibility. We decided to use 80/20 which is like an "Erector Set" for grown-ups.
80/20 consists of heavy duty extruded aluminum struts and a mind-boggling variety of joints, connectors, hinges and fasteners. You can build anything from a table to a robot with 80/20.
The posts will be attached to the concrete floor with 80/20 floor plates and the square tubing will attach into the channels on the posts. At least that's the theory!!
