THE Defining Spaces is a centerpiece project of the United Architects of the Philippines-Davao Chapter (UAP Davao). It is an annual construction exhibit showcasing architectural and building products of leading suppliers and construction industry partners in the country.

Started in 2007, it is one of Mindanao's premier and longest-running construction exhibits. The affair is a three-day event that brings together architects, engineers, contractors, architecture students and end users to participate and enjoy a variety of activities filled with fun, excitement and learning experience. Aside from the exhibit itself, Defining Spaces also includes technical presentations, lectures, forums, games, raffles, student competitions, performances from invited artists, as well as fashion shows.
