I designed a kitchen counter top with two shelves around an under-counter fridge, and built it together with a housemate all within a day. We used only recycled wood. The legs are actually made out of 8 slats from an old bed frame, glued together in pairs. The counter top and shelves were the top and bottom of an old wooden cabinet. I cut everything to size with a hand saw and I’m proud of how straight I managed to cut everything. :)
Only things to do still are sand and varnish it, as well as mount the aluminium strip along the stove side and the rear.
