THERE are stirrings and rumblings that Harlem’s long-dormant 1800 Park Ave. site is springing to life.

Sources say Vornado Realty Trust – led by the dynamic Steve Roth and Michael Fascitelli – is in the middle of several tenancy agreements.

One would have Time Warner Cable relocate its headquarters from Stamford and take the office space in the base of the building.

The retail team, led in-house by Sendeep Mathrani, is also directly working with Nike Town and Bed Bath & Beyond to become the retail anchors of the proposed building.

No one from Vornado returned our calls.

As we advised last year, Vornado Realty Trust completed its agreements with previous developer Michael Caridi and his group, as well as agreements with the College of Podiatric Medicine, which owns the site and has leased it to the developers to 2051.

The 36,289-foot development site is on the west side of the Park Avenue block front from 124th to 125th Streets.

It can produce a 500,000-foot office building, and includes 126,281 feet of air rights from an adjacent property also owned by the college.

This will become the largest development in Harlem and could change the area’s dynamics.

Be aware, however, that no new building plans have yet been filed with the Department of Buildings.

Naturally, the New Year is bringing out a slew of new office offerings.

Fans of Irish pubs will raise their glasses at the idea of owning not one, but two – albeit on long-term leases – within steps of Grand Central Terminal, as well as the attendant office structures above.

The long-established Patrick Conway’s at 48 E. 43rd St. is a watering hole we know well, having lifted pints there for many years.

The traditionally fitted out pub has lots of stained glass, dark woods and good vittles. The building is a mere 23,000 feet but has another 30,000 feet of air rights.

The other pub is Annie Moore’s located at 331 Madison Ave., a 90,000-square-foot office building with an additional 16,000 feet of air rights for, ahem, upside.

The package being sold by a long-holding family is expected to trade separately or individually for a total of about $70 million.

It is now being marketed by the Fearless Foursome of Richard Baxter, Scott Latham, Ron Cohen and Jon Caplan of Cushman & Wakefield.

The same quartet is also shopping 417 Fifth Ave., which should bring in about $250 million for owners Murray Hill Properties and the GE Pension Fund.

The 12-story building includes a penthouse and overlooks the New York Public Library and Bryant Park. It is 90 percent occupied to tenants that include Turner Broadcasting, CIBC and Atari as well as Zale’s diamonds.

Most intriguing is the 80,000 feet of development rights, which can lead to a lovely new edifice. Think 8,000- to 10,000-foot floor plates rising eight to 10 stories – perfect for full-floor hedge funds.
