Jessor became known for ensuring working-class families had proper social amenities in their daily lives. He included entrance foyers, eat-in kitchens with windows, and bedrooms with cross-ventilation, so working-class families without air-conditioning could benefit from natural breezes. At the time Jessor was an architect, air-conditioning was especially expensive. He eschewed the typical railroad flat design, which required walking through one room to get to the next, favoring a design where rooms were accessed from a common hallway, providing more privacy to the residents.
