Two new office tenants have signed on to join Legacy Central, the ambitious mixed-use project to redevelop the former Texas Instruments campus in Plano. Developers on Wednesday announced that IT support and consulting provider Roland Technology Group had signed a lease along with The 20, a business development group serving IT providers. Together, the companies will lease 22,761 square feet of office space at the southwest corner of US 75 and Legacy Drive, according to a developer release. “We had been looking for space for months to accommodate our tremendous growth,” Tim Conkle, CEO of Roland Technology Group and The 20, said in the release. The companies are slated to move into the first phase of the redevelopment project in May. The full project is expected to be complete by the end of 2019. When complete, the redevelopment project will supplement the existing office campuses with apartments, restaurants, retail stores and green space. The additions will replace the fields and parking lots that previously ran between the offices and US 75.
