About Us

Our History. Over six decades.

In over six decades, Sebastian Construction Group has established its reputation as the leading name in construction for premier residential estates in Texas.

Beginnings. From WWII to the 70's.

Sebastian Construction Group was founded in 1948 by George Sebastian, a Dallas native, Southern Methodist University graduate, and self-trained architect. After returning home from the Pacific Campaign in World War II, he began building "post-war" houses to support the expanding Dallas population. The company, initially called George Sebastian, Builder was born.

In the mid-50s, the company slowly transitioned into the high-end Dallas market, focusing on the renovation of the grand homes in the Highland Park area.

By the 1970s, Dallas' residential market shifted, and the tear-down / re-build construction process gained new prevalence. This new method helped create what became the company's primary market: the design-build approach to new, high-end residential construction.

Changes Lead to Growth.
John Sebastian Takes the Reigns.

After earning his degree in architecture from Texas Tech University in 1982, George's son, John Sebastian, began working with the firm full time. Over the next 10 years, George and John worked together to further develop their very specialized market niche. In 1991, the company's name was changed to Sebastian & Associates to reflect the increasing role John played in their growth and development.

After George Sebastian passed away in early 1992, John made two significant changes in the direction of the company: he eliminated in-house architectural services, allowing them to focus solely on construction; and he integrated commercial contracting systems directly into the company to improve quality control, scheduling, and costs.

Mastering Complex Projects
Using a Sophisticated Approach.

During the past two decades, John Sebastian's primary focus shifted to large-scale and complex projects that demand a highly sophisticated approach to construction management. In addition, many long-time relationships with national architects spread the company's scope market and reach to locations well beyond Dallas.

Recently, the company's name changed to Sebastian Construction Group to recognize the group of long-time associates that has contributed to their success, as well as, to combine the group of companies that had been formed to manage these projects in locations across Texas.

Sixty Years and Growing.
Sebastian's Legacy Moves Into the Future.

Over the last sixty years, John Sebastian and his father before him, succeeded in creating a reputation and a way of business that attracts and develops the best talent in the residential construction industry today.

Sebastian Construction Group's deep leadership roots and specialized expansion has continuously evolved, but their passion for quality and strong personal commitment to their clients has never changed.

John's strong personal drive and commitment to Sebastian Construction Group's success will allow it to continue to produce residences of the highest quality – homes worthy of the Sebastian name – for many years to come.
