Now that a group led by developer David Waldman has completed acquisition of the Save the Children headquarters on Wilton Road for $11.9 million, attention shifts to his plans for the riverside property and on where the relief agency's next move is.

By late this week, however, neither was prepared to reveal their future plans.

Waldman declined Wednesday to say what his plans are for the two-story, 58,000-square-foot building on the west bank of the Saugatuck River.

He is also a partner in the development team that plans to the Bedford Square complex on the site of the downtown Westport Weston Family Y, where work is set to begin sometime next year after the Y moves to a new home on its Mahackeno campus.

Save the Children, meanwhile, plans to relocate next spring from the headquarters at 54 Wilton Road it has occupied about four decades, according to Susan Rich, vice president of marketing and communication for the international children's relief agency.

Rich said Wednesday that when the organization moved to Westport in 1974, it had 75 employees. "We now have approximately 900 employees and 300 of them work in Westport," she said. "We always knew this building would not accommodate us as we grew."

She said Save the Children will be leasing office space elsewhere, but declined to give a location or say whether the headquarters would remain in town.
