It may not look like much from the outside, but that's only because Frank H. Stowell & Sons, Inc., is busy displaying its architectural prowess elsewhere. With a client list filled with hospitals, public buildings and high-end residential projects, the company brings its sense of modern design to bear on a number of works in Chicago and beyond. With three generations of family ownership, this architectural firm has been changing the face of Chicago for nearly 100 years. It was founded in 1912, and the principles that successfully launched the firm still guide it today: a unique, fresh approach to every project, and a special relationship with the client each and every time.
