Scott, with a background in finance, joined his father and they have been building new communities and custom homes together for the past 12 years. Brian, retired law enforcement, has been coordinating team projects throughout theSeacoast ensuring buyers have a positive experience during their home build process.

They’ve put their stamp of uniquely designed floor plans on countless large new home communities throughout the Seacoast and are set apart by their unsurpassed attention to detail, thoughtful designs, and an intimate understanding of what goes into your new home and neighborhood. They embrace the value of building green, evolving with lifestyle needs, and ultimately creating spaces that are livable, authentic, and carefully crafted. We have an in house architectural designer, that differentiates us from other builders cookie cutter homes we see all over the Seacoast. “It’s why the homes we design today aren’t like those built a century ago—or those we’ll build a century from now.”

Quality built for energy-star efficiency, our floor plans offer flexible, open, modern day layouts designed to fill your home with natural light!

These landmarks symbolize the O’Neill families commitment to enduring quality, and they take pride in being part of the New Hampshire landscape.
