New England Development
New England Development was founded by Stephen Karp in the 1970s, initially focusing on retail real estate development. The firm grew to become one of the largest privately held shopping center developers in New England, with a portfolio that includes properties like the Northshore Mall in Peabody, MA, and the Atrium Mall in Chestnut Hill, MA. Wealth originates from decades of commercial real estate development and management. The firm's investment strategy encompasses core real estate holdings, infrastructure projects, and private credit investments. Its portfolio includes direct ownership of retail centers, mixed-use developments, and land holdings across Massachusetts, New Hampshire, and Rhode Island. New England Development has also participated in private credit transactions, providing capital to regional developers and operating companies. Team size and AUM are not publicly disclosed. The firm operates with offices in Santa Fe, NM, and Newton, MA. Stephen Karp's son William Karp serves as President, overseeing day-to-day operations and investment decisions. There are no known philanthropic foundations or adjacent vehicles publicly linked to the firm. New England Development is structured as a single-family office that retains a hands-on development capability — it both manages existing properties and originates new ground-up projects, a vertical integration uncommon among family offices that typically outsource such operational expertise.

Frequently asked questions
Who runs investment decisions at New England Development?
Stephen Karp, founder, retains strategic oversight, while his son William Karp serves as President and manages day-to-day investment decisions. The firm does not publicly disclose a CIO or other investment professionals (per public record).
Is New England Development a single-family office or a real estate operating company?
It functions as both. The firm develops, owns, and manages commercial real estate directly — a structure where the family office retains development capabilities rather than outsourcing to third-party operators. This vertical integration is rare among family offices.
What investment stages does New England Development target?
The firm targets direct real estate development and acquisitions, typically ground-up construction or value-add repositioning of retail and mixed-use properties. It also participates in private credit transactions as a lender to regional developers (per public record).
What is New England Development's known posture on co-investments alongside external GPs?
The firm does not publicly disclose a co-investment program. Given its private structure and limited public presence, it likely invests directly rather than through fund-of-fund vehicles, but this cannot be confirmed (Altss estimate).
Where does the underlying wealth for New England Development come from?
The Karp family wealth originates from retail and commercial real estate development spanning over four decades. Stephen Karp was one of the pioneers of the enclosed shopping mall format in New England (per public record).
Does New England Development maintain philanthropic structures, and how are they separated?
No philanthropic foundation or charitable trust is publicly linked to New England Development. The Karp family may have personal philanthropic entities, but these are not disclosed in relation to the firm.
Which regions does New England Development focus on?
The firm's real estate holdings are concentrated in the northeastern United States, particularly Massachusetts, New Hampshire, and Rhode Island. Its private credit activities may extend to other regions, but this is not publicly documented (per public record).
