United Architects, Inc., a Miami architectural firm with offices in Coral Gables, has been in continuous operation in Florida 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.  Lastly, Ms. Castellanos holds a Florida real estate license.  This means that not only can she help you with your design needs, but she can help you purchase investment properties.  You can read more about this here - why an architect-realtor would be a great asset when buying income-producing property.  For starters, we can study the zoning of the property for you so you don't make a mistake purchasing a property for an intent that cannot happen under the zoning code.  We are familiar with Miami 21, the zoning code for Coconut Grove and downtown Miami, as well as the zoning codes of Coral Gables, Miami Beach, North Miami, South Miami, and Miami-Dade County, among others.

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.  If you are in the research stage, you may want to read some of the free articles that appear here.

You may wonder why you should talk to us.  Maria Luisa Castellanos, R.A., has been living and practicing architecture in the Miami area for over 30 years.  This gives her a familiarity with the local officials, the zoning codes, and the Florida Building Code, which will enable you to get your project built faster and with fewer complications.  The zoning code for each city is different.  For example, the City of Coral Gables has a Board of Architects which must review all modifications to existing buildings and residences as well as all new construction.  Yet, not all of them have review boards.  The City of Miami Beach has review boards for the historic districts and for residences that are larger than the normal size.  So, it is important to pick an architect who is familiar with the different cities and zoning codes and processes.

 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 cannot be done.  I can help turn your vision into reality. 

If you want to read how to build a commercial building addition in Miami, input your information in the adjacent box and you will receive an article called, "11 Steps to Building a Commercial Building in Miami".

It covers what to look for before purchasing land, such as testing, the various phases of a design project, and actually building a project - from initial phases to closeout.
