A Home for the New Economy

February 25th, 2010

Builders tend to define themselves by their buyers. Who’s your target market? Move-up families with kids? Downsizing empty-nesters? Millennials? The creative class? People who love smooth jazz and wire-haired fox terriers? During the boom, psychographic preferences were parlayed into what builders hoped would prove to be market-differentiating features, from pet-washing stations to wine caves to poker dens.

But as we enter a new age of pragmatism, the goodies that were once deal-closers are backfiring. Fully loaded homes are unsellable now that buyers can’t afford houses built around their hobbies du jour. They’re no longer treating home as an ephemeral commodity to be swapped out with each life change or whim.

Instead, many homeowners are finding that what they really want are flexible dwellings that can expand and contract with them as their physical, relational, and financial circumstances ebb and flow. It’s no longer feasible to uproot when that second baby is born, when grandma moves in, when the kids leave for college, when one spouse launches a home business, or when the other gets laid off.

At the same time, builders looking to mitigate risk are realizing that in order to stay afloat, they must build smaller, less prescriptive homes that can appeal to a broader swath of the population—all the while value-engineering their plans to provide more bang for the buck.

But there’s a fine line between universal appeal and vanilla design, and the need to differentiate remains. How do you build something practical and compact that still feels special? Do you shrink the entire floor plan equally, or do you abide by different rules of proportion? How do you parcel out a limited construction budget to create the most value? And how can you make one structure work equally well for buyers at different stages in their lives and in different tax brackets?
For answers to these questions, Builder turned to designer Marianne Cusato, who is perhaps best known as the creator of the original Katrina Cottage. Who better to ask? Disaster relief is what this beleaguered industry needs right now, and that includes a pro forma or two that skittish lenders will be willing to bankroll. Cusato joined forces with building scientist Mark LaLiberte, and came back with a no-nonsense plan that wastes little, appeals to many, and can be built just about anywhere.

Including on the Web. Unlike previous Builder show homes, this one isn’t a brick-and-mortar structure. It’s virtual. Why? Because the beauty of this versatile little house is that it can be configured in, oh, so many ways—more ways than we could possibly have space for in print. We showcase a few variations here, but for a full tour you can visit www.builderconcepthome2010.com.

Dollars and Sense

How much does our Home for the New Economy cost to build? Construction costs vary by region and the level of finish will greatly impact price, but Cusato estimates that the basic house can be built for about $110 per square foot, excluding land costs.

Simple Architecture

Let there be no doubt this is a smart little plan that faces the recession head on. At 1,700 square feet, the Home for the New Economy is essentially a saltbox with another box tacked onto the back. In other words, it’s uncomplicated massing that’s easier, faster, and cheaper to build—particularly from a framing and foundation standpoint—than a house with lots of bump-outs and undulating roof forms.

 “Somewhere along the line, homeowners were told they needed 10 gables or they didn’t measure up,” says Cusato, whose book, Get Your House Right, lists this phenomenon among a litany of superfluous extras that end up devouring construction budgets.

“When you don’t have tons of gables, you aren’t putting money into extra flashing in the peaks and valleys of your roof, or in a patchwork quilt of different materials on the front elevation.”

Take away those expenses and you can spend more on features that serve multiple purposes—such as a deeper porch that doubles as outdoor living space. Or double-hung windows on all sides that channel natural light and allow cross-ventilation, thus reducing the burden on the HVAC system. Aesthetics alone aren’t sufficient justification for any one line item, Cusato cautions. There’s more value for the buyer in features that do double, or triple duty.

Apply the same value test to every other design decision and four-sided architecture suddenly becomes doable, she points out. Better to perfect one clean element—say a 6-foot window and trim detail—and repeat it consistently than to muddle up the face of the house with 10 competing pieces of eye candy that give the front elevation the fake appearance of a façade in the backlot of an old movie studio.

Even Smart Builders Continue to Neglect the Attic

February 25th, 2010

Chances are that you design and build your houses with a vented attic. This is the most preferred (and affordable) method of construction for most builders, and if you’re in the right climate, it’s perfectly fine. But a growing number of researchers say many builders aren’t doing a good enough job to make the space energy-efficient.

I recently discovered how important the attic space is to the overall energy efficiency of a house when I had an assessment done on my small, c. 1975 three-story townhouse in Hyattsville, Md.

My house has a three-year-old SEER 14 HVAC system, insulated replacement vinyl windows, and fairly decent (preexisting) fiberglass insulation. With three months to go in 2009, my electric bill is already $1,655.90. If history is any guide, by the end of the year I will have paid $1,865. And this is with a relatively mild Washington summer.

It’s been a mystery that my electricity bill continued to rise even though I have taken measures to help reduce it. A price hike by my utility provider, Potomac Electric Power Co., is one part of the explanation. But recently I found another: My unsealed and uninsulated attic was literally sucking conditioned air out of the house and money right out of my wallet.

This is partly the reason I’m uncomfortable in my house, why my house is dusty (despite my fastidious efforts), and why my electricity bill for one person was way out of control, says Dan Robinette, a comfort advisor at Minnick’s, a Laurel, Md.-based heating and air-conditioning firm that participates in Maryland’s Home Performance with Energy Star program.

“Most attics are under-insulated and poorly sealed,” says Robinette, who did the assessment of my house. “This is a big problem when it comes to the comfort of the home. These two things affect everything from the temperature in the upper levels, to the air quality, to the number of times your A/C is running in a day. So with a little time and materials and you can get that attic sealed up, insulated, and be on your way to a happy home.”

Robinette’s recommendation? Seal the attic and have 13 inches inches of cellulose blown into the space, which is what I did.

“Air sealing and insulation have a large impact [on a house],” says Amber Wood, program manager for energy efficiency at the NAHB Research Center in Upper Marlboro, Md. “Before anything, you have to seal all penetrations into the attic such as electric boxes, ceiling fans, knee walls, and attic openings, but you have to make sure the soffit vent can ventilate or it can lead to moisture problems.”

Sealing the attic and blowing in insulation—either cellulose or fiberglass—establish the house’s thermal envelope, help prevent air leakage, and help maintain the temperature of the conditioned space below.

“In cold weather, warm air is continually rising,” Denver-based insulation manufacturer Johns Manville says on its Website. “Leaks into the attic allow the expensive, heated air to escape into the attic, while at the same time drawing in cold air to displace it from the basement or other exterior leaks. This continuous air movement makes the home feel drafty and raises energy bills. By sealing attic air leaks, you plug the escape route of rising air and effectively stop the chimney effect.”

Other common sources of attic leaks that Johns Manville says should be checked include: areas between floor joists and behind kneewalls, the attic hatch, wiring holes, plumbing vents, recessed lights, and the furnace flue.

The sealing and insulation of my attic came in at a shade under $1,400. Robinette says—and other consultants agree—that this is typically what it costs. (During my assessment, he also discovered that my house has severely leaky ducts and proposed AeroSeal treatment to have them sealed from the inside out, which he estimated would cost another $1,900.)

André Desjarlais, who manages the building envelopes program at Oak Ridge National Laboratory in Oak Ridge, Tenn., says Robinette made the right call on my attic. In fact, Desjarlais says people don’t realize just how important the treatment of the attic space is in the overall energy efficiency of a home.

“There are lots of stats,” Desjarlais says. “But let’s take the average home with 2.3 people. Half of the energy bill for that home is used to heat and cool it. Half of the remaining [portion] is due to energy losses through the attic.”

It would be logical to assume that under-insulated attics is a problem largely for older homes, and in some ways this would be an accurate assumption. Older homes tend to be leaky and poorly insulated, and some construction techniques from yesterday may not be appropriate for how homes are built today. “Yes, the older [the homes] get, the worse the problem is,” Robinette says.

But Mike Barcik, senior research engineer and director of technical services at the Southface Energy Institute in Atlanta, says attic inadequacies aren’t only relegated to old homes; many new homes suffer from the same ailments. “I would say 90 percent of all existing homes need some improvement and are probably under-built, including those built two years ago,” Barcik says. “I might even up that to 98 percent.”

The problem with new homes, Barcik continues, is that building inspectors are largely focused on safety, and so a home’s energy usage gets overlooked. “The energy code is a fantastic code if it’s enforced, but it’s not enforced in many states,” he explains. “We have done blower tests to prove it.”

Neglecting the attic seems unthinkable given that it’s relatively cheap to address during construction of the house. Wood says, for example, that a builder may pay about $100 to $500 more in material to seal and insulate an attic. “It’s not that expensive,” she says. “They can do it either with foam and fiberglass, or they can use caulk. Caulking takes more time, but it’s inexpensive.” So the tradeoff is a $500 upfront cost compared to the $1,400 I paid to retrofit my house? That sure sounds like an investment that would be worth considering for new-home buyers and their builders.

Walk On It

February 25th, 2010

After the walls, the floor is the most visible surface in a house. And because the floor is such a commanding presence, home buyers typically spend a great deal of their spending power to make a personal style statement with it.

The floor, says San Francisco Bay Area–based Interior Floor Design, is “the foundation upon which we build our castles, our empires, our humble abodes” and “a reflection of who we are, how we got here, [and] where we want to go … .” Well, the floor may not be as profound as all that for most people, but you get the idea: It’s a big deal.

Whether out of style preference or complacency, most consumers choose to stick with traditional options—wood, vinyl, ceramic, carpet. These materials serve buyers well, and they have proven themselves over the years. But for those willing to walk on the wild side, there is a vast world of materials to choose from: recycled rubber, cutting-edge Italian and Spanish ceramic tiles, reformulated linoleum, carpet tiles, woven vinyl, and even concrete.

After years as an “alternative” material, once exotic bamboo flooring has almost worked its way into being classified as a mainstream option. Today, it is regarded as a high-quality material that is durable, attractive, and sustainable.

Bainbridge Island, Wash.–based Teragren, known for a variety of bamboo products, has a new offering called Synergy. Unlike traditional end- or flat-grain bamboo, Synergy is a strand product that is manufactured by fusing bamboo strands with adhesive. The company claims that Synergy is about 150 percent harder than red oak and 125 percent harder than North American maple.

Most people are familiar with cork boards, fish bobbers, and wine stoppers, but fewer may be aware that the material can be used as flooring. “The resilient quality of cork makes it a great option for areas where people stand for long periods of time,” says Lancaster, Pa.–based Capri Cork. “It is easier on the limbs than other hard surfaces.” Because the individual cells of cork are closed, the material does not easily absorb liquids. As a result, it performs well in wet areas.

For those who want to step out even further on the edge, there is leather. But not just any leather. Mississauga, Ontario–based TORLYS recently unveiled a new floating floor system that is made with 65 percent recycled leather scraps from the manufacturing of jackets, belts, and handbags. The company mixes the leather with 35 percent natural ingredients such as resins. As the company explains it, the leather is adhered to a high-density fiber core and a cork backing for comfort, warmth, and quietness. So far the reviews have been good.

“We’re absolutely thrilled with the positive response we have received from the design community and consumers who are seeking a highly styled and sustainable alternative flooring,” says Charles Lammers, the company’s vice president of U.S. sales. “They love the combination of unique rich looks, durable wear, and environmental benefits.”

For the truly intrepid buyer, there is aluminum from AlumaFloor in Addison, Ill. The material is the epitome of urban cool, ideal for lofts, high-end condos, live/work spaces, or adaptive reuse projects. AlumaFloor can be designed in any shape a buyer wants, the company says, and is machined so pieces fit tightly and need no grouting.

Of course, there are things to remember no matter what flooring option you’re considering. First of all, alternative materials are not for everyone. The trick is to know when and where they are appropriate.

It is highly unlikely, say, that a family with kids will choose metal (though given the material’s durability it may not be such a bad idea). Leather seems highly impractical in a kitchen, but it may work nicely in a study or an office. And bamboo may be all the rage, but—depending on the finish—it is important to know its limitations with heavy foot traffic and high moisture. If you keep these things in mind, you will help your buyers choose a floor that they’ll be happy to walk on and show off to guests for many years to come.
