GRAND RAPIDS, MICH. — At the end of January, Grand Rapids-based Locus Development will break ground on Thirty-Eight, a mixed-use project located at the corner of Weston and Commerce in downtown Grand Rapids. The eight-story, 80,000-square-foot mixed-use development will include 35 one- and two-bedroom apartments on floors two through six; eight two-story penthouse condos on floors seven and eight; a 30,000-square-foot office component; an open-air rooftop bar space that accommodates up to 150 people; and 10,000 square feet of ground-floor retail space dedicated to small shops and restaurants. Additionally, a seven-story parking ramp with space for more than 360 vehicles is being constructed as part of the project. The parking structure, which will include the city’s first green roof, will be situated adjacent to the mixed-use building and will offer direct access to retail, offices and residential units from each level. The approximately $26 million project was designed to achieve LEED certification. Prior to construction, Adtegrity.com signed a lease for 15,000 square feet of office space at the building. Situated on the second and third floors, Adtegrity.com’s new office will have space for up to 50 employees. The company is expected to take occupancy in the second quarter of 2010. The project is scheduled for completion by the end of the year.
