AN office condo build ing located at 100-104 Fifth Ave. on the northwest corner of West 15th Street is in contract for just more than $150 million.

The approximately 270,000-foot building was purchased back in June for $110 million by Atlas Capital Group’s Jeff Goldberger and Andy Cohen.

They have since divided and sold the retail and now the 20-story building is being bought by a London-based investment firm, Rock Investments.

The Atlas boys came out of UBS in 2006 and also own the Meyberry House at 220 E. 63rd St. as well as properties across the pond in London.

A grand pre-war Upper East Side apartment house hit the sales market on Monday and could fetch, around $100 million.

The building at 150 E. 72nd St. at Lexington Avenue has 40 lavish apartments that have fireplaces, high ceilings and formal dining rooms, including one in which luxury residential broker Alice Mason holds her society-filled dinner parties.

Developer Edgar Levy bought the land in 1912 and the current owners, who live in the building, have had it in the family since 1934.

Rents have never been “pushed,” even though the building is now 80 percent free market.

Richard Baxter, Ron Cohen, Scott Latham and Jon Caplan of Cushman & Wakefield are marketing the site.

The group is separately selling another pre-war building at 130-40 and 130-50 Ash Ave. in Flushing for the same owners that could go for $30 million.

It was built in the 1930s, and has 140 units that are 100 percent rent regulated.

The former Lower East Side bar and music joint Mo Pitkins, where Debbie Harry, Moby and others have rocked the so-called “House of Satisfaction,” is up for sale for $4.75 million.

The bar, whose investors include “Saturday Night Live” alum Jimmy Fallon, closed in October after its renovation debt-load became too much to carry.

There is a ground-floor restaurant and bar with a transferable liquor license, a performance space on the second floor, office space on the third floor, and an approximately 1,000-foot residential duplex on the fourth and fifth floors that includes a 700 foot-plus terrace.

The basement has an office and recording studio.

Sure, the average cost of a square foot in New York City is in the triple-digits, but a new Cushman & Wakefield survey shows that office space in the Big Apple is a relative steal compared with other world cities.

According to the survey, which covers 2007, New York is now the 10th most expensive city in which to lease office space. Last year, the city was ninth.

“New York remains an attractive place to locate a business,” said Ken McCarthy, the head of area research for Cushman & Wakefield.

“We are seeing a number of foreign banks come into New York and the US has the most liquid capital markets,” he said. “If you are a global player you have to be here.”

London ranked the highest at $311.58 a foot, followed by Tokyo at $238.58 and Hong Kong at $210.12.

The Big Apple remains a great buy at $100.28 a foot.

Gainers include Singapore, which at $130.48 a foot put the city in seventh place, up from 17th a year ago, thanks to demand from financial services companies.

Oslo, Norway, also made a big leap year over year to 11th place from a year-earlier 25th. Cushman & Wakefield said that city’s average office rent of $99.42 was fueled by strong demand and high prices for its oil exports.

If you spot a black, British-style cab in front of 55 W. 99th St., it’s the property of The Week, which just moved its headquarters there from the nearby 1040 Avenue of the Americas.

Owner Felix Dennis imported the taxi to be ready for the 40 staffers who also enjoy a saltwater fish tank in the offices.

Clyde Reetz of CB Richard Ellis repped The Week in the eight-year sublease that had a $34.50 asking rent from I.A.T.S.E, which was repped by Brian Weld of Colliers ABR.

The building owner is Steinberg & Pokoik.

The vacant Booth House on 318 E. 15th St., which started being de-aquisitioned by New York Downtown Hospital last year, was finally purchased for $56 million by Arun Bhatia, who’ll renovate the 140-unit building into luxury apartments.

“We got about 40 offers for the building,” said Yoav Oelsner, who marketed it with Cushman & Wakefield colleagues and Jon Epstein and Charles Kingsley.
