The owners of this 1960s ranch house loved their house but it wasn't configured to meet their needs. The house had only two small bedrooms for the family of four, and there was no casual living space for parents and kids to hang out separately. Neither we nor the clients wanted to increase the home's energy usage. It was a tall order: could we increase the home's size without increasing its energy footprint?

ADDING FUNCTIONALITY
We built two small additions, one at the front of the home and one off the side adjacent to the two existing bedrooms. These new spaces provided an additional bedroom on the main level as well as a new stair down to the basement. At basement level, the additions yielded a guest room, a full bathroom and a laundry area. The existing basement, which is now easily accessible from the main floor, was refinished as a casual family room.

The architect designed the new spaces to be spare and bright, replicating the mid-century aesthetic. Every detail—from the open stair, to the light maple floors, to the detailing of the bathroom vanity—echoes the vintage and character of the original home.

INTEGRATING ENERGY AND DESIGN
The key to meeting this challenge was a rigorous and integrated planning process with early-stage energy modeling accompanying design. As the architect (Anita Rogers) worked out the space plan, the energy consultant (Mike Duclos) analyzed how various scenarios could be combined with envelope and mechanical packages to not only hold the line on energy use but improve performance. We anticipate the plan we settled on will save 25% annually over pre-project energy use.
