A trio of developers are planning 65 townhomes in Detroit’s Woodbridge neighborhood. The $18.5 million development is at 3700 Trumbull St. between Selden and Brainard streets. The joint venture is a collaboration between Detroit-based Tekton Development, Detroit-based Civic Companies, and Bloomfield Hills-based Robertson Bros. The development would have 48 one-bedroom townhomes with about 1,300 square feet and 16 two-bedroom townhomes with about 1,600 square feet. Construction should begin in the fall and be completed within three years.
