SIR Development
For more than three decades, SIR Development has been creating exceptional luxury homes in Westport and throughout Fairfield County. Founded in 1993 by Robert and Julie Haroun, the company was built on their shared commitment to refined design, superior craftsmanship, and extraordinary service. Since then, SIR Development has completed more than 300 residences and earned a reputation as one of Fairfield County’s most respected homebuilders.
Every SIR home begins with a thoughtfully selected property and a clear vision for how the home should look, feel, and function. Our fully integrated team—including experienced project managers, skilled craftsmen, interior designers, custom cabinetry and millwork specialists, and landscape professionals—works collaboratively throughout every stage of the process. This continuity allows us to maintain exceptional quality, precise craftsmanship, and a cohesive design from the ground up.
In 2024, Robert and Julie’s daughter, Annie Haroun, joined SIR Development after years in the corporate world at PepsiCo. Annie worked side by side with her father, learning every aspect of the company and preparing to carry forward the standards and values that have defined SIR Development since its founding. Today, Annie leads the company’s day-to-day development and construction operations, working closely with Julie, whose legal, real estate, sales, and marketing expertise has helped guide SIR Development for more than 30 years.
Following Robert’s passing in July 2026, his vision, integrity, and unwavering attention to detail remain at the heart of the company he and Julie created. Under Julie and Annie’s leadership, SIR Development continues as a family-owned and operated business, supported by the same experienced team and longstanding relationships that have been central to its success.
We stand behind every home we build, including providing a dedicated follow-up response team for a full year after closing. With SIR Development, buyers receive more than a beautifully designed house—they become part of a lasting tradition of quality, service, and thoughtfully crafted homes built to be enjoyed for generations.
