In the United States, each architectural firm usually has at least one principal, an architect who is the sole owner of the firm or has a percentage ownership along with other architects in the firm (either as a partner in a partnership or as a shareholder in a corporation).[5]​ Sometimes the title of principal is limited to owners who have a certain percentage ownership of a firm, or can be expanded to include anyone with a leadership role.[5]​ Some firms also use the title principal-in-charge, which Designates an architect who oversees the studio's services related to a specific project.[5]​.

In the UK and other countries, the principal of an architectural firm is responsible for professional practice. This is usually a qualified architect, engineer or designer.

Small studios with fewer than five people usually have no formal organizational structure, but instead rely on the personal relationships of owners and employees to organize work. Medium-sized studios, with between five and fifty employees, are often organized into departments such as design, production, business development, and construction management. Large studios with more than fifty people are usually organized into departments, by regions, or into studios specialized in different types of projects.[5]​.

Advances in information technology have made it possible for some studios to open offices or establish alliances with other studios in different parts of the world. This makes it possible for some of the work to be done in countries like the United States or the United Kingdom, and other parts in places like India or Mexico, for example. In addition to using highly qualified, low-cost professionals in Asian countries, it also allows some studios to work, in effect, in two or three shifts due to time differences.

It is important to note that developers in India and China are increasingly hiring European and American studios to work on local projects. Often, their work is coordinated by or subcontracted to architectural firms in these countries, in effect outsourcing work to European and American firms. The recent market situation has led to an acceleration of this trend and an increasing number of architectural firms in India and China are outsourcing work to Western architects.
