In the spring of 2002, bungalow homeowners and professionals gathered to exchange ideas to create adaptable and energy efficient Chicago bungalows. Concepts and preferences exchanged in this charette became a reality in the four model bungalows.

The Historic Chicago Bungalow Association and City of Chicago, the Chicago Chapter of the AIA and various local agencies arranged to purchase and rehab four vacant bungalows ... Each model home was rehabilitated to conform to the Historic Chicago Bungalow Initiative Design Guidelines and to incorporate a wealth of energy efficient, environmentally friendly products and design ideas. You now have the opportunity to tour each bungalow and see, in detail, the innovative design solutions.
