Undergoing years of careful planning and construction, Calvin and Orsula Knowlton’s estate stands as a symbol of modern luxury.
Spanning more than 40,000 square feet, the home represents the pinnacle of craftsmanship and innovation in architectural design.
Its setting in southern New Jersey offers proximity to some of the nation’s most prestigious universities and healthcare companies.
The property’s grand entrance, featuring dual floating staircases, sets the tone for the rest of the residence, which is as functional as it is beautiful.
With exquisite detail throughout, this mansion is poised to become one of the most significant homes in the Philadelphia metropolitan area.
Auctioning a Dream Home
Calvin and Orsula Knowlton, the healthcare moguls who spent an impressive $27 million constructing this 40,000-square-foot estate, have opted to auction the property for less than half their original investment.
The couple first acquired the 7.7-acre parcel in 2017 and initially planned to restore the existing 19th-century farmhouse.
However, extensive mold issues forced them to demolish the structure and create their grand vision from the ground up.
Situated across two New Jersey townships, the project faced numerous delays, including waterlogged land and complex approvals.
Despite moving into the mansion in 2022, the Knowltons have made Florida their primary residence
After traditional listings failed to generate significant interest, they turned to an auction with a reserve price of $10 million.
The auction, set to close on October 9, presents a unique opportunity for potential buyers to acquire this luxurious property at a fraction of its original cost.
