Who We Are Where We Build A Custom Home Get In Touch

Welcome to Mark Sullivan Builders! We take great pride in building with an emphasis on each client's individuality as it translates to their home. Put ourĀ over sixty years of combined craftsmanship experience to work and we will help you realize theĀ dream of your custom-built home.


Our homes can be seen in communities and countrysides in and around Williamson County, Tennessee - some of the Nashville area's most beautiful settings for the distinctly-crafted projects we have been honored to complete.

We collected a list of local contractors and researched qualifying metrics: quality, trust, accessibility, meeting timelines, warranty, managing costs and customer satisfaction. Our choice was Mark Sullivan.

Mark Sullivan and his crew were focussed on exactly what we wanted. Communication was open and clear. Building our house was a pleasant experience.
