Exhibit 99.1

FOR IMMEDIATE RELEASE

Trinity to Acquire Luxury Park Slope Mixed-Use Property

NEW YORK, NY (September 11, 2017). Trinity Place Holdings Inc. (NYSE: TPHS) announced today that it has entered into an option agreement to acquire a newly built 105-unit, 12-story apartment building in Park Slope, Brooklyn for $81.0 million. The property includes 6,264 square feet of retail space, a portion of which is leased to Starbucks Inc. The transaction, which is subject to customary closing conditions, is expected to close in the first quarter of 2018.

Located on the border of the Park Slope and Gowanus neighborhoods of Brooklyn at 237 11^th Street, the property is one block from the 4^th Avenue/9^th Street F, R and G subway station. The building is also a short walk to nearby amenities such as Prospect Park and Whole Foods Market as well as many of the borough’s best restaurants and boutique shops along 5^th and 7^th Avenues.

237 11^th Street offers an array of modern amenities that surpass what is available in the neighborhood’s “brownstone” housing stock. Apartments feature a washer/dryer in all units, tenant-controlled HVAC units, stainless steel appliances, and private outdoor terraces. Building-wide amenities include a courtyard garden, party room, fitness center, tenant lounge, bicycle storage room, parking, and landscaped rooftop terrace. The property’s relative height offers panoramic views of the New York Harbor and the Manhattan skyline from upper floors and the rooftop.

The property benefits from a 15-year real estate tax abatement under Real Property Tax Law Section 421-a. All the units in the building are market rate, but are subject to rent stabilization guidelines.

Following the closing and pursuant to a separate agreement, an affiliate of the seller will continue to manage and promote the building for a limited period and an affiliate of such manager will have the ability to receive an additional payment based on the performance of the property during such post-closing period.

In addition, on August 4, 2017, TPHS closed on the sale of its property located in Westbury, New York for a gross sale price of $16.0 million. The sale resulted in an estimated gain of $3.9 million and generated approximately $15.2 million in net proceeds to TPHS. The net proceeds from this sale will be used to partially fund the 237 11^th Street acquisition.
