The luxury market slipped last week: It registered 16 contracts signed in Manhattan at $4 million and above, 10 fewer than the previous week. Condos outsold co-ops, 10-5, with 1 townhouse in the mix.

The No. 1 contract was West 28AD at 500 West 18th Street. asking $22,120,000. It is 2 units that will be combined by the sponsor and will total 5,355 square feet that offers Hudson River views, 6 bedrooms, 6 bathrooms, and 2 powder rooms. The combination was sold to a local buyer who missed out on another unit in the building. It is the 5th time this year that an apartment in the building took the top spot in this report, and it is particularly noteworthy because the building--originally called the XI, which launched in 2018--landed in a spectacular $1 billion-plus foreclosure. By 2021, the new sponsor, Witkoff, took over construction and rebranded the building. Now called One Highline, it offers a robust amenity package--a fitness center, 75-foot lap pool, spa-treatment rooms, a golf simulator, children''s playroom, private dining, a games lounge, and a garage. Services are offered from the adjacent Faena Hotel, which is part of the rebranded project.

The No. 2 contract was PH at 137 Duane Street, asking $18 million, reduced from $19.995 million when it was listed in April. The condo has 4,942 square feet including 4 bedrooms, 5 bathrooms, a den, and a screening room, plus 4 terraces totaling over 7,200 square feet. It features a landscaped rooftop terrace with an irrigated lawn, paved paths, and native grasses. The seller purchased the unit for $7,280,488 in February 2008 and spent years extensively renovating. The 5-story, 19-unit building has no amenities.
