In days of old airships were huge, gas giants. Make them big but without the gas. If you check on the structure of half mile wide geodesic domes they will lift off the earth with a temperature differential of 1 degree inside to outside. Think "Independance Day" in overall shape and your there. Big, heavy lifting and not difficult to build. Bigger is better..
