DALLAS--Gaedeke Group LLC has unveiled the design of One Legacy West, 327,856-square-foot office building on an 11-acre site at the southeast corner of Sam Rayburn Tollway and Legacy Drive in west Plano.

Gaedeke's 14-story project will be the first multi-tenant office space to deliver in the $2-billion Legacy West, a 240-acre mixed-use urban development currently under way by Karahan Cos., KDC and Columbus Realty Partners. Gaedeke Group will break ground this summer and deliver the project in fourth quarter 2016.

"The diversity of the Legacy area gives us a unique opportunity to design and develop a concept that will compete on national and international platforms," Sabine Gaedeke Stener, CEO of the Dallas-based investment firm, said in a release. "Our benchmark was to create a high-quality office environment that's not only efficient and functional, but one that energizes and inspires."
