I built this Stand Up desk for a Minister friend of mine who likes to write his sermons standing up, while having all his reference materials at hand. The over all dimensions are close to 46" high, 30" deep and 66" long. Materials are Honduras Mahogony primary wood, Maple base, Poplar secondary and some birch plywood for the interior surfaces. The writing surfaces have black cowhide leather inserts. I put in a couple of secret storage spaces to make more fun to build.
