Your Dreams. Our Heart.

A Flenn Custom Home is the result of true collaboration between owner and builder!

Your family is unique and so is the way you live. Your new home needs to function properly in everyday life and perfectly on those memory-making special occasions. It should incorporate your ideas and your style to create a seamless combination of aesthetics and function.

Getting there takes effort, of course, but it doesn’t have to be frightening or frustrating. It seems everyone has heard nightmare stories of houses that didn’t get built the way the owner wanted or took forever. With Flenn, we make building a custom home a rewarding and exciting experience for our clients.

We have a passion for helping families take their dreams and make them a reality. After all, we’re a family business. We understand that in a home built just the way you want it, everything works. There are places to gather and places for quiet. There is plenty of storage with no unused rooms and no wasted space.

A home built just the way you want it brings you value and peace!


Our Process


You may opt to bring your own plans, or we can create a custom design for you. Either way, we can build exactly what you are looking for.


Every plan has a price. Is it the right price? Is it the right plan? Finding that balance is what makes a great builder. We’ll work with you at every step.


Building a dream in the physical world is the purpose of design. We will make sure that your ideas are accurately displayed on the construction documents.


We’ll organize the resources, materials and craftsmen needed for your build. We’ll keep you updated on the progress and apprised of any recommended changes.


The goal of landscaping is to accentuate the home, not overpower it. We’ll work with you to integrate the new building in the existing environment.


We treat every project with the same care we would give to our own homes. The job isn’t finished until the work is done and you are satisfied.

We make your dreams come true! Below is an example of a home where the owners brought us their own plans, and we did the construction.

Recent Projects

While interviewing builders, I casually mentioned a concern about having enough property for a single story (I had a three story blue-print at the time). Greg looked left to right and stated he thought it could be done. A custom design was launched. I was involved in the building process and never felt left out of the loop.


Greg was responsive, conscientious, accountable, and reliable. Even when the project was complete, we could count on him to address details that needed attention. He is honest and hardworking, a builder whom I’ve already recommended to friends, family members, and clients. We’re very happy with the work that was done and Greg’s job of overseeing every aspect.


I had always heard that by the end of the building process you would not be on speaking terms with your builder, not so with Greg. He is welcome at any of our family functions.


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.
