These plans and specs are all that you will need to either build a ranch house yourself or, alternatively, put the project out to bid for construction by a general contractor. Certainly you could go to a traditional house plan company and buy large format plans, but you don't need large format plans and they would cost you several hundred dollars. This is a ranch house after all and is as simple and straightforward to build as can be. I have contracted for the construction of well over 50 ranch houses using these same 8 1/2" x 11" format plans without any issues. Further, house plan services often don't provide a full set of technical specifications that are bid-ready like the ones presented here are.
