Established in 1971, Portfolio Construction is a diversified building enterprise. Our current focus includes moderate to custom built luxury homes, multi-family dwellings, and condominium construction. With over 500 homes completed in the New England market ranging in value from $99,000 to over $1,200,000, we are an industry leader in both quality standards and construction experience.

David J. Gagnon, founder and president of Portfolio Construction, is a native of New Hampshire who truly understands what his customers are looking for in a new home and a builder. Today, he still personally oversees all of the company's operations on a daily basis. With over 35 years of experience in the building industry, he is a master builder who demands quality from his employees and his subcontractors. His ability in and knowledge of the construction industry is that of an expert, and his work and past projects represent it. As a drafter he also takes an active role in the design and layout of custom projects, offering his customers ideas and suggestions to make their new home perfect. He is one of the very few developers in the area that is ranked as a master builder.

Our company's competitive advantage has always been our reputation. We have worked very hard to build a rock solid reputation in the industry. The company's philosophy was built around extremely high customer satisfaction ratings, well built homes and pride of workmanship. We are one of the only local developers that have been building homes for over 30 years with continued growth, steady referrals, and repeat customers. Our long-term goals include continuing this reputation for another 30 years.
