Ambler’s Lindenwold Castle, inspired by Windsor Castle, is up for auction with a reserve price of $1.5 million, reports Ryan Mulligan for the Philadelphia Business Journal.

The 134-year-old castle is approved for residential units and office spaces. It does, however, retain the potential to sell as a large single-family home.

The sealed-bid auction, conducted by Paramount Realty USA, began last week and ends on Dec. 19. Lansdale architect Milton Bean originally built the property for industrialist Richard Mattison in 1890. Over the decades, much of the land sold, leaving the castle on 1.13 acres surrounded by modern developments.

In recent years, owner Leonard Poncia invested $3 million in preserving the stone exterior and updating systems. The interior still requires substantial renovations. Appraised at $1.9 million in 2022, the property’s auction format lets buyers determine its value.

“What we do lends itself very well for unique, special properties,” said Misha Haghani, founder and CEO of Paramount Realty USA.

Within walking distance of Ambler’s vibrant downtown, the castle’s location offers appeal to developers and private buyers alike. Its history mirrors that of Ambler’s transformation, from an industrial hub to a thriving suburban enclave.

“I think the sky’s the limit in terms of who you could attract here, but it’s ready to be renovated,” said Adam Gillespie, a broker with Avision Young who has the listing.
