The Brownfield Medical Building was Gregory Ain’s only Inglewood building. Designed for two doctors, the small building was very straightforward. The plan consisted of two offices with a shared waiting room between the practices. Noted for simplicity and planted court, Brownfield was one of Ain’s rare non-residential projects.

The building was substantially remodeled, masking the original design. Some Los Angeles architectural historians, including the influential David Gebhardt, believe that the Medical Building was actually destroyed. It was not.
