Meet Greg Flenniken

Greg is a construction engineer and has been building homes for more than 40 years!

“Building homes is my passion. I truly enjoy the process of helping families take their dreams and make them a reality in a home that fits their unique lifestyle.”

Greg is a husband and a father of four. His business is family-owned. So it’s no surprise that he places a great deal of emphasis to listening to clients and building homes that give them the function and aesthetics they want along with the value they need.




Recent Projects

My name is Dudley Porter and I have been in construction most of my adult life.  I am the President and Owner of Porter Products and have been selling building products and contracting roofing and home building products for over 40 years.  I have known Greg at Flenn Custom Homes and done business selling him and delivering windows and doors for his projects for over 3 years.

It has been my opinion and still is that Flenn Custom Homes delivers first class Home Building and Remodeling projects with exceptional results exceeding construction expectations.  The many hours of endless detail required to estimate a building project and doing what he says he is going to do are paramount in his business model.

I would recommend Greg and his co-worker, vendors and suppliers for contracting jobs today and in the future for building projects throughout the Central Texas Region.  Plus he is a first class guy.
