In 2018, Berggren Architects was hired to complete an addition for the John Bell Residence, also known as the Ernest A. Calling House. The historic home, located in Gothenburg, Nebraska, was built in a vernacular Queen Anne style with Neoclassical elements on both the interior and exterior. The character of the house lies in its irregular massing and variety of roof and window shapes. Berggren Architects provided plans and elevations for approximately 1,000 square feet of new living space, including space for new stairs and the relocation of the master bedroom.
