United Architects, Inc.

A Miami Architecture Firm

We turn raw ideas into plans for comfortable, livable, inspired buildings and residences in Miami, Florida.


We love to design.  We love creating.  We are passionate about creating wonderful, useful spaces, whether it's a 2-story commercial building or an addition or remodeling to a home.  And this passion will ensure that you will get something truly valuable as far as beauty and functionality. See some of our projects below.

United Architects, Inc., a Miami architectural firm, has been in continuous operation for over 30 years, founded by the principal of the firm, Maria Luisa Castellanos, R.A.  Ms. Castellanos holds a Master of Architecture and a Bachelor of Science from the Georgia Institute of Technology, in Atlanta, Georgia, USA.  She also holds LEED AP certification which prepares her for consulting on “green” or sustainable projects.

Our work appears throughout this entire website.  Some pages have our work and some pages are entirely informational.  Some give background on the city and the county in which we reside. Others give information on the architectural design and construction process.   We hope you find the website interesting, engaging, and useful to you.

 Call to set up a complimentary initial appointment to discuss your project. If you call me, Maria Luisa Castellanos, the principal of United Architects, at 305-439-7898, I will come out to your property in Miami-Dade County, and give you a free evaluation of your ideas.  In that meeting, we can develop a clear vision of what can and what cannot be done.
