Initally it wasn't too stable with cross-wind or pushing, so that's why I made the kick stand out of 4x4's with a 2x4 base and spread the rear axles to full 3'.
I designed it using photos of other coops and ideas from several things. I put in a removable floor so it could be hardware wire during the summer, then a sheet of plywood in the winter.
I used wheels off a Harborfreight (HF) 1000-lb garden cart, but the rear axle i had to make. The frame is treated 2"x4"s that have been ripped to 2"x2" because they cost the same as 2x2 here. No good sources for recycled wood that I was aware of so I had to buy new lumber. The siding is rough cut cedar and has been sealed with bher fence finish.
Right now it's got a HF solar powered light, but I don't need to much lights. I haven't tabulated the cost, but it was cheaper than premades but more than I would have liked. I guestimate about 600-700$ after everything. I could have saved some money by using waferboard, or plywood, but hey the wife doesn't ask for much, and so I figured I would make something no one could complain about.
