About LR3 Development

Paul LaRoche is owner and co-founder of LR3, a custom luxury home building firm located in Southern New Hampshire.

With 25+ years of experience, he’s established himself as an industry leader and created luxury markets where others have said it couldn’t be done. His standards and commitment to quality are second to none and he is the best of the best when it comes to custom, quality homebuilding…


LR3 Development designs elevated homes and spaces, our projects have been featured in mainstream publications such as The Wall Street Journal, HAVEN Lifestyles, and Dwell Magazine, in addition to local and regional publications. Our clients connect with our modern, clean, and thoughtful designs, and it’s our goal to create a home that’s a warm, inviting, intentional, and stylish place to live.


Building your home is an honor, a privilege, and the ultimate responsibility. With decades of deep ties to the community, we are proud to know and work with only the best in the business. Every set of hands involved in the process of building your home, from beginning to end, is chosen, with extreme care and consideration, by us. Our commitment to these high-priority relationships can be seen in the unparalleled quality of your home. Transparency and understanding expectations matter most and are paramount to our ability to communicate and problem-solve at the highest level.


With over 200 acres of pristine land in our development, Cranberry Meadow Estates, LR3 Development has curated a business model that seamlessly transitions from individual projects to multi-home developments. Before we consider the home, we process the needs and desires of the land, the environment, and the community in order to establish the impact of development. With so much local land in conservation or destined for conservation, our model allows us to design and build beautiful homes with breathtaking views while honoring the need to protect the land of the Monadnock Region.
