I am planning on constructing a new building at my house for use as a machine shop including cnc machines. I am planning on around 30 X 56 X 14 frame construction with one 16 x 12 door in one end. I would also like to put some type of overhead crane in. Already have a 2 ton track crane at my disposal, and plenty of I-beams for construction. For anyone who has built a building themselves for a similar purpose can you provide me any advice from hindsight and what might be some nice features to include when planning the building.
