Building a new home requires meticulous management in the office as well as on-field proficiency. Would-be homeowners need to select a residential expert that knows how to craft a functional space that will suit their needs. Our editorial team decided to compile the best custom home builders that operate in Southampton.

They were chosen based on key factors that include portfolio quality, background, accolades, and feedback. Not all of these companies are not based in the city, as some firms are located in adjacent neighborhoods.

If you are thinking about building a custom home, we recommend checking each builder’s license with the local licensing board, speaking to past clients, and using our bidding system to get competitive quotes from at least 3 contractors. Getting multiple bids is the best way to ensure you get a fair price and that bids include the complete scope of work.
