CORNELIA STUMPF AND CELESTINO PIRALLA DISCOVERED THEIR IDEA OF A HOUSING GEM in Magnolia Park, a suburb in Savannah, Georgia.

The couple made an offer within 45 minutes, even though many of the home’s original features were covered up or in disrepair.

HERE'S SOMETHING you don’t see every day: an “aging in place” multiple unit housing project with sustainability front and center.

This urban project in downtown Santa Barbara, CA, takes to heart architect Ed Mazria’s 2030 Challenge goal of carbon neutrality. Built in two phases, and certified LEED-H Platinum, it began with the teardown of an 1887 Victorian house, and its replacement with a state-of-the-art 2,520-sq. ft. home. The new structure captures some of the essence of the original home, but is extremely airtight and well built. The combination of spray foam and external Tyvek ThermaWrap reduces air infiltration (ACH 50) to .96 (better than the most stringent LEED standards).

The second phase called for construction of a 5,100-sq. ft. three-unit condominium, designed in a Spanish style. This condo was built using the same framing and insulation materials as the single-family home, and it also achieves super energy efficiency. The team had intended to build both structures with SIPs, but seismic concerns resulted in a change to 2”x6” framing with spray foam and thermal wrap.

The addition of parking lifts not only allowed for more vehicles—it conserved valuable square footage for living, so that the architect was able to squeeze an additional living unit out of the plan. Less driveway also made possible communal gardens in between the buildings.

Island Jewel

Ellis used the short eaves space upstairs to store a single Geyser heat pump water heater. He needed to provide enough capacity for four bathrooms and an outdoor shower. So the two hot water tanks act as storage and are plumbed in line with the Geyser heat pump providing heat for the system. The heat pump runs on standard 110 volt power. As the systems use ambient hot air to heat water, they blow out colder air, cooling the “outdoor” hallway. Also in this space is the 4.5 ton 16 SEER Trane high-efficiency heat pump that conditions living areas.

PROBABLY THE GREENEST way builder Steve Ellis could have used his island property would have been to continue enjoying it as a festive site for bonfires and camping.

WHEN YOU SEE A TULIKIVI masonry hearth in a custom home, you know you’ve entered a rarefied green home. It’s as revealing as seeing a Rolls Royce parked in a home’s garage (although that sends a very different message). You already know a lot about the owners.

Mayan Makeover

THIS UNUSUAL WHOLE-HOUSE REMODEL began with a mostly gutted home in an old Austin neighborhood.

 

“The owner has a fascination with Mexico and Central America,” recalls builder David Kettler. “He started with a little backyard garden area, and really got into it and researched a lot. He had been working on the project for a couple of years, but he had trouble with some of the guys he brought in to do the work. They tended to be a bit unreliable.”
