The race to develop Gotham’s most family-friendly luxury rentals is getting even hotter thanks to the arrival of The Easton.

The 230-unit tower at 205 E. 92nd St. launches leasing March 10 and gives NYC families a special nod, and not just with its larger units.

Sure, the building’s three-and four-bedroom dwellings (beginning at 1,600 and 2,200 square feet, respectively) offer plenty of space for growth, but there’s also a robust kid-friendly amenity package.

The Post got an exclusive first look at these jam-packed features, part of a larger trend of new developments with major kid-focused areas across New York.

The Easton will house a 3,000-square-foot indoor/outdoor play area, as well as a separate 3,000-square-foot space called The Agora — an ancient Greek word that means gathering place.

Much of The Agora’s focus is educational.

It will have carrels for homework, dedicated study rooms for students who bring in their tutors and three sound-proof rehearsal studios — two of which feature Steinway pianos for private music lessons, while the other sports a ballet barre for dance practice.

But it’s not all for serious pursuits. The “tween room” will have a gaming arcade and lounge for watching movies.

The building will charge a to-be-determined fee for access to The Agora.

What’s clear is that pricing for initial availability will range from $4,400 for a one-bedroom to $15,995 for a four-bedroom.

“The family segment has grown in Manhattan,” says Bryan Cho, executive vice president at Related Companies, which is developing this 39-story ground-up project, adding that families in need of larger homes have been an underserved portion of the market. “Families of all ages have chosen to remain in Manhattan, as opposed to [moving to] the suburbs.”

Of course, there will be ample amenities for older residents when the building opens in May. They include a penthouse-level lounge and billiards room, a party and dining room with full-service catering kitchen, plus landscaped terraces with barbecue grills and panoramic city views.

Related Rentals will handle leasing of the units, whose kitchens and bathrooms come designed by architect S. Russell Groves.

One- and two-bedroom pads include custom oak cabinetry, oak flooring, ceilings over 9 feet high and wireless controls for temperature and lighting.

Meanwhile, three- and four-bedroom units, which begin on the 30th floor, will deliver separate kitchens with Sub-Zero, Miele and Wolf appliances, 10-foot ceilings and smart-home features.
