Another UN deal on Third.

The United Nations International Computing Center, an organization that provides data processing and information technology services to the United Nations and the UN's World Health Organization, has leased the 24th floor of 730 Third Avenue.

Based in Geneva, Switzerland, the International Computing Center, abbreviated as UNICC, had for years used the UN's Secretariat Building for its Manhattan operations.

But that office tower, along with most of the other buildings on the UN's East Side campus, is currently undergoing a $1.9 billion renovation that has required thousands of staff to be relocated to other locations.

Andrew Roos, an executive at the real estate services firm First Service Williams, handled the lease for the UNICC and said that the organization was being displaced by the work being done to the UN campus, but that it had also been planning to take separate facilities in any case.

Roos just completed another deal in the building, a 120,000 s/f lease of the building's entire 8th, 9th and 10th floors for general offices of the United Nations.

That deal was not prompted by the renovation, according to Werner Schmidt, a public affairs officer for the UN, who described it rather as "the UN doing its normal leasing of real estate" for various staff that need space beyond what can be accommodated in its existing facilities.

"Some of the people who move in are probably affected by the master plan, but not necessarily," Schmidt said of that deal. "This is just the general space needs [of the UN]."

Most staff displaced by the renovation work, which will take place over the next five years, have been brought to two large temporary office spaces the UN leased in recent years near its East Side site; 380 Madison Avenue and the Albano Building on East 46th Street.

The UNICC will be taking 8,345 s/f at 730 Third, a far smaller space than the UN has leased.

Because 730 Third Avenue tapers, its tower floors ate much smaller than those in the base of the building.

The space was being offered by the pension fund TIAA-CREF, which owns and occupies most of the building. Roos said that both the UN and the UNICC deals were "the prefect combination of an institutional owner matched with an institutional tenant" and that TIAA-CREF was very "UN friendly."

Some landlords have been hesitant to take the UN in as a tenant because of its security requirements and because the agency has attracted controversy.

Roos said that the 24th floor featured an existing office installation that the UNICC would be able to utilize and that both the UN and the UNICC had been attracted to the building's amenities, which include access to TIAA-CREF's conference room facility on one of its floors as well as its cafeteria.
