Dixon Residence

Building a Family’s "Forever Home"

The Opportunity

Builder Khair Zaman of Z Works Design Build col­lab­o­rat­ed with the Dixon family from Dripping Springs, Texas to create their forever’ home in the most sus­tain­able fashion possible. The Dixons’ desire was to have a green home that would allow them to live effi­cient­ly and minimize their utility costs. They also wanted a modern and minimal design for their home that would call for very little maintenance.

Key Design Features

The Dixons were looking for a wall system that would both lend itself to the stur­di­ness necessary for a forever home and require minimal main­te­nance over time. They wanted to knock on the walls of their home and imme­di­ate­ly feel reassured that it would not be going anywhere. They also did not want to find them­selves having to con­tin­u­ous­ly maintain and repaint the exterior of their home to keep it looking presentable.

Based on the location of where the Dixons wanted to build their home, it was necessary to incor­po­rate a natural water system, such as a well or a cistern, into the build. A rainwater col­lec­tion system was the ideal choice for all parties, as it provides a water quality superior to that of a drilled well. It was important to Zaman and the Dixons, though, that the water system did not detract from the overall clean and minimal aesthetic of the home. A large cistern sitting outside of the home would have inevitably had that effect.

In a state like Texas, where the weather is ever unpre­dictable, it was also important to the Dixons that they have top-quality insu­la­tion in their walls to keep the interior tem­per­a­ture of the home at a steady constant. This would not only keep their utility bills low, but it would also make for a greener and more energy efficient home, which was another major priority for the Dixons.


Z Works Design Build used the Bautex Wall System to create a resource-efficient and low main­te­nance home that the Dixon family will be proud to call theirs for the rest of their lives.

Low Energy Costs
Low energy bills have had a big impact on the family’s budget, hitting a peak of $120 in the heat of the summer but staying very low the rest of the year. This home is solar and net-zero ready.

100% Rainwater
The home incor­po­rates a 20,000 gallon cistern inside the thermal envelope under the bedroom wing to provide clean and fresh water and doubles as a thermal mass” heat sink to create more stable indoor tem­per­a­ture year-round.

Low Main­te­nance
Solid walls with durable finishes give the owners a sense of living in something that will last forever and take very little maintenance.



By using the inno­v­a­tive Bautex Wall System, Zaman was able to help the Dixons create their forever home. The dura­bil­i­ty of the Bautex Block will allow the walls of the home to stand up to the harshest of elements. Con­struct­ing the walls with Bautex materials also made it possible for Zaman to integrate a rain col­lec­tion system within the building envelope of the structure so they would not need to have a massive cistern outside of their home.

The inte­grat­ed insu­la­tion of the wall system keeps the internal tem­per­a­ture of their house at a constant and their energy bills low, regard­less of what is going on with the weather outside. The 20,000 gallons of rainwater that are collected within structure provide further insu­la­tion, which makes this home extremely efficient.

As for the aesthetic of the home, the Bautex walls fit perfectly with the modern and minimal look the Dixons were going for. Contrary to the mis­con­cep­tions that an ICF wall limits the design palette, the Dixons’ wall system is capable of being enhanced by any number of exterior finishes. The Dixons incor­po­rat­ed wood and metal wall finishes in several areas of the house.
