The Trinity Mixed Use project, developed by R+R Development and Bourn Companies and designed by Rob Paulus Architects, is located directly adjacent to two Modern Street car stops in the center of the Historic West University neighborhood. The project will replace unused buildings at the Trinity Presbyterian Church complex located at 400 W University and replace the adjacent parking lot to Time Market. The project will offer two new buildings at three and four stories with ground floor retail in both for 7,000 sqft, 24,000 sqft of office space and 58 market rate apartments.

The three story office and retail building (shown in the photo above) is complete with its first tenant being HealthOn University. The residential and retail building (rendering below) will replace a southwest portion of the Trinity Presbyterian Church. View the site plan below.
