Check out this book. The author goes into this and other overlooked ways to save material in chapter 2. (He even uses the exact image you linked.)
A lot of other posters seem to be dismissing this as not saving that much money. But the author gives all kinds of examples about how being smart about keeping components aligned cascades down the line. But when you stay in this "lego block" mentality, small savings roll into big bucks. Being smart about staying in standard unit lengths not only saves on the framing, but also the flooring, roofing, windows, carpeting, ductwork, plumbing, and trim.
Really recommend this book. It’ll explain the whole homebuilding process, the major decisions and their relative trade offs.
The Complete Guide to Contracting Your Home by Kent Lester and Dave McGuerty was the most useful step-by-step homebuilding book I've read, and it includes a lot of tips on how to reduce costs.
I'd really recommend picking up a copy of this book.
The author walks through the entire process of building a house, step-by-step. He very clearly lays out the different options and what tradeoffs come with them. Most importantly he comes at it from the lens of being cost-effective and easy ways to save money in the process. Even if you don't end up being your own GC, it'll really help you understand how to control costs.
I'd recommend reading this book. It basically lays out all the steps to building a home, what the options and tradeoffs are, and the best way to save money if you decide to be your own contractor.
