See The Potential of Your Space…Virtually!

You’ll absolutely love the Dreamception Design Program. You’ll sit down with one of our incredibly talented interior designers and see your home vision spring to life! When homeowners first consider a remodeling project, many of them worry what it will look like and often struggle with trying to figure out how to get the look they are going for.  With Dreamception, our designer is able to come into your home, review your ideas, and create several different design options to maximize your budget and give you the greatest return on your investment. You’re then able to view these plans in a virtual 3D model so that you can see what the finished build will actually look like – all before any physical construction or major costs are even considered!

Additionally, with a licensed Real Estate Agent on staff, we can additionally provide our clients with facts pertaining to the housing market which will help them determine the best path to moving forward, whether they want to sell or remodel.  Having the ability to provide our clients with options of what their current house can look like and comparing it to what is currently on the market is priceless. We pride ourselves on honesty and integrity and will go above and beyond to make sure our clients are satisfied.

Dreamception… because every concept should start with a dream!

Three Easy Steps

First, you’ll meet with our amazing  designer. During this meeting, you’ll discuss your overall budget for the build to determine what options will be available. You’ll then share your ideas, and our designer will then point out some options that you may not have considered.

After our designer has completed the designs, you’ll meet again. You’ll be presented with your virtual plans for two different designs that will meet your budget. This virtual packet will include virtual 3D renderings so you can see what the build will potentially look like.

Third, once you’ve chosen the plan you’re interested in, our designer will complete up to two design alterations to meet any desired upgrades or changes. These could be as simple as adding a door up to major changes in infrastructure.

This home in located in historical downtown Georgetown, Texas  Our clients were looking for a new look, but had to keep within the confines of building code requirements.  Through the Dreamception Program, we completely changed the floorplan and added a carriage house with a balcony.


Formal Estimate Guarantee

Have you ever heard of a Money Pit?! It’s not something that you want to experience with the building or remodeling of your home. It’s important for us at Flenn Custom Homes and Remodels that you have reassurance when it comes to how much a build or remodel will cost from the very beginning. With our Formal Estimate Guarantee, we guarantee that the price you contractually agree to is the price you end up paying – both material and labor included. With forty plus years of home building experience, we know what to look for up front so that you’re not stuck with any unwelcome surprises later on!

On-Time Guarantee

At Flenn Custom Homes and Remodels, we understand that life can feel unsettled during a new home build or renovation – your life feels upside down and uncertain, and you want to know when you can plan for things to be normal again. Being able to plan is imperative when money is going out the door to pay for temporary living or storage arrangements. This is the reason Flenn Custom Homes and Remodels offers an On-Time Guarantee! Once we contract a finish date, we guarantee that we’ll be finished on time or we’ll pay you $100 for each and every day thereafter until the build is completed!

Limited Lifetime Labor Warranty

At Flenn Custom Homes and Remodels, your satisfaction in our work is important to us – both now and in the years to come. As such, we only provide the absolute best service and craftsmanship. Our Limited Lifetime Labor Warranty guarantees to you that we’ll perform all work in a professional manner using only high-quality materials and supplies, and in conformance with local and state building code standards. Flenn  warrants all building and installation work that we perform to be free of defects due to workmanship for as long as you own the home where the building or renovation service has been performed.

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.

Dudley Porter

We have been so pleased with the beautiful job Greg’s crew has done. We have enjoyed our home being with family and friends in a comfortable environment. I especially have enjoyed my lovely, perfect and functional kitchen.

I would also like to add: we have only ever done small remodeling jobs on our homes never a complete remodel and design. I was NOT looking forward to this project in any way!

Greg Flenniken was such a huge help with his encouragement keeping me on schedule even when I was at my worst. Greg is a man of integrity and moral character. Bringing that to the table combined with his years of experience completes a beautiful home that brings years of enjoyment to the home owner.


I have worked with Greg two times in the past 15 years on remodel projects on my home. He was patient during the planning and budgeting process. He always answered calls, text or emails promptly and guided us through the project without any problems or frustrations. He and his crew were respectful of us, our home and even our pets.

Even though we were out of town for most of our last remodel, he finished on time and on budget. I would recommend Flenn Custom Homes to anyone looking for a builder they can trust with the home if their dreams.


We had an extensive remodel project on a family home and had total confidence in Greg Flenniken’s ability as a builder and as a person to complete the job to our high standards and to be able to combine the old and new features in a fluid way.  He exceeded our expectations.  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.
