New Building In Greenwood Reaches Construction Milestone Construction of a new 85,000-square-foot office, retail and entertainment building on North Greenwood reached a milestone Monday as crews hoisted the final beam in a topping out ceremony. Developers said the project played a big part in bringing another new building to the block, one of great importance to Greenwood. Developers of 21 North Greenwood are excited about the new office and retail space, but they're just as excited about their new neighbors, the Greenwood Rising History Center. "Really just proud to be associated with Greenwood and build projects that the men and women who made Greenwood great would be proud of," said Developer Kajeer Yar.
