The creators of the Kavouri Residence are Sergio Palleroni and Margarette Leite, the husband-and-wife partners of the Austin, Texas- and Portland, Oregon-based pldp architects. Architects as well as educators now teaching at Portland State University, Palleroni and Leite are perhaps best known for socially responsible work done under the banner of pldp and of BaSiC Initiative, a design-build community outreach program affiliated with multiple schools.
The homeowners of the dramatic Kavouri Residence site, a pair of photographers, first learned of Palleroni and Leite through this body of work. Attending a wedding in Mexico, the married couple stayed in a pldp-designed house adjacent to a BaSiC Initiative-designed library and weaving workshop, and quickly decided to hire pldp for their own project. Intended to replace the dilapidated home of the wife’s grandfather, the Kavouri Residence—or, more specifically, its budget—bears little resemblance to pldp’s do-good works. Yet architect and client used the extravagant resources for achieving high standards of sustainability and execution, rather than ostentatious or energy-gulping display. “The building ends up being very simple, but there’s a lot of thought about how it fit into the site, the views it had, and the extraordinary selection of materials,” Palleroni says.
Like Greek temples and vernacular coastal homes, the Kavouri Residence looks out toward the port and the Acropolis. Fully completed last year, it stands exactly on the footprint of the old homestead, and reuses a sizable portion of that structure. “We took all the materials after the excavation, sorted it out for earth and clay content (there’s probably 3 percent cement in there), and made rammed-earth floors,” Palleroni points out.
The material was laid carefully on top of radiant heating and cooling pipes, and the results have the appearance of old leather. They are finished simply in linseed oil, because, Palleroni also notes, "finishes are where a lot of the contaminants are."
In another example of reuse, an old stone wall is incorporated into the photography studio adjacent to the house. Bordering those elegant floors, the house rises on a concrete frame filled in with Porotherm, a honeycomb brick produced in Austria. The brick’s cellular construction earns it an R35 rating, but still allowed local masons to erect the house according to tradition.
“We put a rigid layer of insulation over the structural columns, so they were equally insulated,” Palleroni adds. “ Basically, if you shut all the windows and doors, the interior and exterior could be totally isolated from each other.” The tight envelope places that much less stress on the hot- and cold-water heating and cooling systems, which are fed almost entirely by a rooftop solar hot water system and from two submerged rainwater cisterns located near the kitchen, respectively.
Of course, the Kavouri Residence isn’t intended for self-containment. Configured around an internal courtyard and punctuated with clerestory windows all around, it begs to be unfurled into the landscape. And just as the photographers’ kids easily skip from deep, low window sills into the courtyard, or down the terraced landscape that surrounds house and studio, so breezes from the harbor of Athens dart and tumble through the building.
