1006 at The Dorchester on Rittenhouse Square

The History

In 1963, The Dorchester on Rittenhouse Square celebrated its grand opening as a luxury apartment building when it replaced a number of traditional homes, including some mansions, on Rittenhouse Square and 20th Street.

William Zeckendorf, the acclaimed New York builder who had developed the United Nations headquarters, built The Dorchester to accommodate Philadelphia's changing population, and the need for more residential apartments in Center City.

Milton Schwartz, the architect, initially proposed two towers with an open-air space between them. Mr. Zeckendorf overruled him, which is why The Dorchester was erected as an L-shaped building. Similar to many of the other buildings on Rittenhouse Square such as The Barclay, The Savoy, and The Claridge, The Dorchester's name was inspired by a London landmark. However, unlike other buildings on Rittenhouse Square, The Dorchester was one of the first buildings of its time to use exposed concrete as an exterior finish. Additionally, The Dorchester offered a variety of units including studio, 1, 2 and 3 bedroom apartments. The Dorchester's array of apartments was in contrast to the Pre-War buildings on Rittenhouse Square that spanned half and full floors.

By the 1970s, rents approached $1,000 per month for a 2 bedroom and attracted the likes of successful business owners, media personalities and elected officials. The Dorchester's penthouse pool was the go to gathering spot for many socialites and their friends.

In 1980, The Dorchester was converted to condominiums by Robert Sheridan & Partners. The Dorchester's condos sold out immediately, mostly to current renters in the building. Over the years, The Dorchester has continued to be one of the most vibrant residential communities on Rittenhouse Square.
