Blackstone Group and Equity Office have finalized a deal to sell a 10-building Burlington office park to local investors for $216 million.

Charles River Realty Investors and National Development have agreed to purchase the suburban office assets in New England Executive Park, totaling more than one million square feet of commercial space.

Combined, the 10 properties in the office park are 86 percent leased. The new owners inherited the rights to build an additional 750,000 gross square feet of new ground-up development, including office, commercial, retail, hotel and structured parking space, according to information from Cushman & Wakefield, which brokered the deal.

The park currently maintains onsite amenities including parking for 3,352 vehicles, two full-service restaurants, a fitness center, bank and credit union

"Charles River Realty Investors and National Development expressed significant interest in the portfolio due to the property’s redevelopment potential, unmatched location and quality of buildings and tenancy," Mark Smith, market managing director for Equity Office, said in a statement. "This sale is certainly mutually beneficial on both ends."

The sale of the Burlington office park is the most recent divestment by Blackstone in the Greater Boston area since the company’s takeover of Equity Office Properties Trust in 2007. Earlier this year, Hines Global REIT purchased the 510,000-square-foot Riverside Center in Newton from Blackstone and Equity for $197 million.
