A fire broke out in an apartment under construction in the Trump International Hotel and Tower early Friday on Columbus Circle, according to reports.

The blaze started around 4:12 a.m. on the 47th floor of the 52-story building at 1 Central Park West.

The fire was sparked when a piece of machinery malfunctioned in an apartment under construction, authorities told WCBS.

The blaze, which forced a partial evacuation of the building, was brought under control at about 5:20 a.m., CBS reported. The upper floors were vented amid carbon monoxide concerns.

One person was treated for smoke inhalation.

The 166-apartment condo tower, which was built in 1996, features hotel-style service, health club, pool, sauna and steam room, among other amenities, according to Trump International Realty.

Residences are located from the 23rd through 52nd floors and are accessible from a private entrance on Central Park West, the realty company website says.
