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.

Mark Sullivan and his crew were focussed on exactly what we wanted. Communication was open and clear. Building our house was a pleasant experience.
- CLINT & CAROLYN CALDICOTT
The building of our house was stress free and timely. Mark Sullivan knows he is not building just another house, he is creating your home. Mark took the time to ensure that our home exceeded our expectations.
