better with age Recycled materials and antique elements add an unexpected dimenison of sustainable style at this carefully designed home.
A hat rack made with antique skis sets the tone for reuse and repurposing at the Ellenberg residence in Los Alamos, New Mexico.
Punched tin panels add hand-crafted charm in the kitchen, where a window onto the adobe passive solar room provides views of the canyon behind the house.
Bob and Karen Ellenberg discovered this carved corbel, now prominently displayed atop a knotted post in the living room, among a pile of scrap wood.
Aged adobe bricks add atmosphere and heat storage ability in the form of a passive solar breakfast room adjacent the living room and kitchen.
Homeowner and builder Bob Ellenberg designed this bottle-shaped fireplace by the staircase.
Outside, the home looks like an updated Northern New Mexico Territorial style hacienda, while the rusted metal roof and rustic entry doorway lend an aged-in-place air.
A refurbished chandelier illuminates the relaxed dining room space—one of the many antiques and architectural elements that find a second chance in this new home.
Tucked alongside a wooded canyon in Los Alamos, New Mexico, sits a new home with an old past. Here a profile of dormers and steep roof lines stands out in a palette of warm red-browns against the sky’s deep blue. At this recently built home, green design and building techniques demonstrate a modern philosophy. But intertwined amid the contemporary construction is a hint of something old. Aged doors grace new door frames—each different from the last because they come from a time before standardized sizing. A knotted juniper log serves as a post in the living room, topped with a corbel the owners believe to be about a century old. Wooden countertops in the kitchen look familiar: they used to be floor boards in a gymnasium.
“It’s so labor intensive to use old materials, but I have a personal love for old things and recycling,” says homeowner and designer/builder Bob Ellenberg. “Conceptually, I like the idea of not being wasteful and using old things.” His company, Robert Ellenberg Inc. Design/Build, is based in Los Alamos. The home’s substantial list of recycled materials includes plumbing fixtures, doors, beams, countertops, metal, wood paneling, interior window sashes, light fixtures, glass block, and weathered railroad ties. Most of the structural wood is composite to avoid using large pieces of virgin timber. Even the juniper post in the living room was recycled from a burned area of the forest.
These elements stretch life out of materials many wouldn’t consider using and provide the home with another layer of interest. “I think it adds a lot of character,” says Karen Ellenberg, who collaborates with her husband on home designs and assists in the day-to-day running of the business.
The original concept for this Northern New Mexico style frame home called for adobe construction. “We were very much enamored with adobe houses and the style of them,” says Karen, who with Bob came to New Mexico from the East Coast. In fact, the pair took an adobe-building class through the University of New Mexico and attended the Southwest Solar Adobe School. “We eventually settled on the idea of incorporating adobe into a new home built primarily of conventional building materials with advanced building methods of energy conservation,” Bob explains.
The home’s roof is made of recycled heavy-gauge corrugated carbon steel. Exterior walls measure nine inches thick with an R value of 34, while the roof system measures 14 inches thick and rates at R-54. Meanwhile, the house has a two-inch-thick layer of polyiso foam insulation with sealed seams. Much heat loss and energy cost comes from air leaking from a house, Bob notes, so he sealed and conditioned the underside of the home to prevent heat from escaping through the floor. The sealed and insulated crawl space means the high-efficiency furnace doesn’t run as often and the floors stay warm. “It’s an incredibly comfortable house to live in,” he says, adding that the utility bills are quite modest.
Beyond the front door and the door from the garage, an air lock entry helps keep heated or cooled air in the house, and the space between doors also functions as the mud room. A HEPA air filtration system promotes good air quality inside.
The Ellenbergs applied passive solar design techniques such as placing glass on the south side of the house to take advantage of solar gain. Off the kitchen and living room, they incorporated adobe construction with a passive solar room built with adobe bricks. They can close off this room from the main house and later throw open the doors to admit heat stored in the thick adobe walls.
Outside, the Ellenbergs harvest water runoff from the roof and hard surfaces, including the driveway. The water collects in a 5,000-gallon cistern in the backyard under the deck. They generally irrigate landscaping with this water. It also feeds the external perimeter fire sprinkler system, which is in place to spray the outside of the house as protection from a fire sweeping through the neighborhood—a particular consideration in Los Alamos, where memories of the devastating Cerro Grande Fire are still fresh. With a backup water supply and generator, the system is satisfyingly self-sufficient. Locally mined stone covers patios and forms the dry-stacked (mortarless) walls on the property.
A phoenix from the fire
The new construction allowed the couple to integrate green-building techniques, but they took care to prevent never-before-used materials from looking too new. Take the bricks for the passive solar room. The natural, unstabilized adobes were artificially aged to replicate the crumbling old walls around New Mexico that Bob loves so much. He created the look by cutting off the surfaces of the bricks and wearing them down with brushes and water. The bricks were finished with a sealer.
When Bob and Karen used a new material, they aged it. The pine plank flooring was scalloped at the edges with a draw knife to make the boards look worn. Punched tin panels covering the kitchen appliances were designed to look like the antique tinwork Bob and Karen saw in local shops. The couple took tinwork classes but didn’t like the shininess of the new tin, so Bob learned how to tone down the new metal and created a motif for the kitchen. The panels were a labor intensive but original element. “They’re truly unique,” he notes.
The kitchen countertops came from a place in Albuquerque that sells, among other things, old bowling alley and gymnasium floors, Bob recalls. They bought huge slabs of gym flooring, which were stripped, sanded, stained, and finished with a varnish for a hard, durable surface.
Even the house rests on a repurposed site. A home stood on the lot until the Cerro Grande Fire in May 2000. Bob worked with the owners, Walter and Dorothy Hatch, who had raised their family in that house, when he came to Los Alamos to work on catastrophe insurance claims after the fire. Although he was building a home in Florida at the time, he and his family liked the area so much, they moved here.
During the claims process, Dorothy’s husband died, and she ultimately decided not to rebuild a home for herself on the lot, Bob recounts. He says watching a new house being built where Dorothy’s old home had stood was a sentimental experience for her. While excavating for the house, they found family mementos that were lost after the fire, such as a stone face one of Dorothy’s sons had carved. “It was a very special thing to see a house go up there,” Bob muses. A sign reading “Casa Dorothea” now greets visitors outside the home.
Practical but “wow”
As he designed the new house, Bob’s first consideration was the site, including its orientation to the sun, views, and topography. He started with the practical questions, then attended to making the house exciting. “My philosophy about designing a home is it’s easy to design a practical floor plan,” Bob explains. “It’s fairly easy to design a ‘wow’ house. The real art and skill is in doing both.”
Upon entering the home, you are greeted by a lovely foyer area with a curved stairway and a bottle-shaped kiva. The walls are coated with a mixture of mud from Abiquiú in northern New Mexico, plaster, and straw. In the living room and other areas of the house, the walls have a polished Venetian plaster finish.
The kitchen, dining and living rooms, passive solar room, powder room, and master suite reside on the main level. Upstairs you find an office, exercise area, loft space, and bedroom wings. One of the wings has a separate entrance and can serve as guest quarters or an apartment. Although it’s designed to flow as part of the home, this space has a sound wall and can be closed off from the rest of the house to help the owners save energy.
Some homes have state-of-the-art wine refrigerators. This house has a wine cellar. The unique, energy-saving feature was built into stone under the house to naturally keep up to 1,200 bottles of wine the proper temperature without electricity. “It’s a little larger than most wine coolers,” Bob jokes. The cellar is accessed through a trapdoor in the floor of the foyer. Bob can remove the rug covering the hatch, open the trapdoor, and descend into the cellar, which is attractively accented with antique stamped ceiling panels.
The panels prove another example of that one-of-a-kind style the Ellenbergs have created for their home. They gathered these elements from a farflung variety of sources—antique shops, scrap sales, a man selling old doors on the side of the road in Ohio—and the hunt provides an enjoyable step in the process. “We absolutely love it,” Karen confesses. The hand-carved corbel in the living room is one of their favorites. The Ellenbergs found it at the bottom of a pile of scrap wood they purchased—$10 for all they could fit in the pickup.
Reusing materials whenever possible, from the architectural details to the structural wood and roofing material, demonstrates mindfulness toward what is consumed during a building project. At another level, it’s a special way to add dimension to a carefully designed living space.
“I believe a house both needs to be a practical place to live and a fun place to live,” Bob reflects. “To me, my house is fun. I’m never tired of it. It’s absolutely fun.”
