New Jersey Grandest Homes: The 6 Largest Ranked by Size
I’ve spent years studying how the wealthy build, and largest houses in New Jersey has some of the most surprising examples I’ve come across. Most people think of the state’s small shore cottages or suburban colonials, but tucked away in towns like Moorestown and Alpine sit some genuine mega-mansions, several bigger than most hotels.
I put together this list at rivon home to rank the 6 largest houses in New Jersey,In this list, I’ll walk you through the 6 biggest houses in New Jersey — starting with Villa Collina, the largest of them all. Curious which one takes the top spot? Take a look below.
Where These 6 Largest Houses in New Jersey Are Located
Two towns do almost all the work here. Alpine, in Bergen County, and Moorestown, in Burlington County, account for every home on this list. Both offer something New Jersey’s denser suburbs can’t: large private lots, strict zoning, and a short drive to a major city, Manhattan for one, Philadelphia for the other.
Just like the largest house in Alabama follows a similar logic, built well outside the state’s denser metro areas. That combination is exactly why these 6 largest houses in New Jersey ended up where they did.
My Personal Tour of These 6 Estates
As Stefano Schiavon from RivonHome, I spent time exploring several of largest houses in New Jersey to appreciate their true scale beyond the photographs. From Villa Collina’s impressive grounds to the secluded mega-mansions hidden throughout Alpine, each property showcased exceptional privacy and grandeur.
Although the gates kept the largest houses in New Jersey out of view, the vast landscapes spoke for themselves. The experience reminded me that, in New Jersey’s luxury market, expansive land and exclusivity are every bit as valuable as the mansions themselves.

A quick note about largest houses in New Jersey before we get into it: Villa Collina holds the most credible claim to the top spot because its size was confirmed through actual tax court filings, not just a listing agent’s estimate.

Why Alpine and Moorestown Keep Showing Up
Notice a pattern? Four of the 6 largest houses in New Jersey on this list sit in Alpine, a small Bergen County borough with no commercial district and just one school. Its location, minutes from the George Washington Bridge, makes it a favorite for buyers who want Manhattan access without living in the city.
Moorestown, meanwhile, offers wide, historic lots in Burlington County, which is why it produced both Villa Collina and the Knowlton Estate.
