GFP has been successful in creating beautiful interior and exterior spaces that offer a pleasing integration of architectural, structural, mechanical, and electrical system elements.

The Origins of GFP

Our original firm began in 1949, with Architect Fernand Picou, shortly after his graduation from Princeton University. Fernand’s focus was designing innovative educational facilities in Lafourche, Terrebonne, Assumption, and St. Mary Parishes, at a time when the need for modern facilities was growing.

A New Partnership

In 1963, after graduating from LSU, Architect Richard Weimer joined the firm to collaborate with Fernand. Richard eventually became the owner of the firm and expanded his portfolio of projects until he transitioned ownership in 2010. Richard remains very active in applying his educational experience to the new owners of the firm.

Looking Ahead

In 2010, Weimer Gros Flores was established when Architect Kevin Gros and Interior Designer Amy Flores teamed up with Richard to carry the firm's long history into the future.


Welcoming New Talent

In 2020, our firm welcomed Architect Lloyd "Andy" Positerry II as a Partner to help us carry our vision forward. Andy is a resident of Houma and a graduate of the LSU School of Architecture with over 25 years of experience in the field.


Houma On Board

In 2021, Architect Houston Lirette and his firm joined the GFP family, establishing the GFP Houma office and continuing their 40-year history of serving the Bayou Region.

Coming to the Capitol

GFP acquired Post Architects, combining the long rich history of both firms spanning back over 50 years for Post and 70 years for GFP. The combined 129 years of firm experience and current leadership and design team talent is positioned to provide its multi-sector focus to the Capitol Region.
