Coming off a Labor Day holiday, you don’t normally expect a banner week in sales. And last week was no exception--only14 contracts were signed at $4 million and above. What’s not so normal is that last week marked the 11th-straight week of sub-20 contracts signed, the weakest stretch since 2012.

The No. 1 contract was the Penthouse at 78 Irving Place, asking $20.9 million. This 4,420-square-foot triplex has 4 bedrooms and 5.5 bathrooms, plus a rooftop terrace with 903 square feet outfitted with a kitchen. Four apartments in this new 7-unit condo went to contract last week, and the building is now sold out. This gut-renovated building has a doorman but no other amenities.

The No. 2 contract was PHB at 305 East 51st Street, asking $11.75 million. The penthouse is being sold by the sponsor HFZ Capital, which bought out its equity partner CIM last month, paying $5,306,386 for PHB. This duplex penthouse has 4 bedrooms and 4.5 bathrooms, plus 2 terraces totaling 1,365 square feet. The unit has dramatic views that include the East River. It is in a new condo called the Halcyon, which has a robust package of amenities including doorman, concierge, garage and a 52-foot pool, plus a sun deck, sauna, fitness center, golf simulator, lounge/library, and bicycle storage.
