This is part of a larger shop renovation I did for a client; you can see the rest of the project here. The three doors to the left of the wide cabinet door are a raised panel bi-fold door system I designed and created specifically for this job. They provide access to a water shutoff and pressure relief system while not eating up unnecessary floor space. A video of them in operation can be seen at the end of this gallery.
When fully opened the allow access to the main water shut off for the house.
