My brother gave me a great book by Ana G. Canizares entitled 500 Solutions for Working at Home. It’s 423 pages of solid inspiration organized by type, including studios design for personal use, architecture, design, art and services. Each case study includes not just beautiful photographs but details, square footage and floor plans. This book is full of clever solutions from humble to lavish. At $15 new / $8 used (at Amazon) your investment could be as little as one and a half cents per studio solution. Of course there is a ton of inspiration online but it can be hard to track down and usually won’t come with this level of detail so this book is pretty good way to augment your search.
