Goodbye to the armoire and the dining room (in many cases, the living room, too). Hello to the home office.

Repurposed rooms, recycled materials and an increasingly relaxed decorating style characterize the end of a decade that began as a party on a grand scale.

These are among the home decor trends cited by experts as the 2000s draws to a close.

During the past 10 years, the formal living room in most homes has been reinvented. It's now a library, workspace, or perhaps a music or game room. Many are now willing to buy a new home without a living room at all, according to a survey this spring by the American Institute of Architects. What people want is some combination of kitchen and great room where the family can interact. Homes are more laid-back and user-friendly.

The most well-liked rooms now are the home office, mud room and media room, the survey indicated. What we don't want so much anymore? Three-car garages, guest rooms and formal living rooms.

While the economic downturn has caused people to scale back their dream-home wish lists, "households are using their homes as intensely as ever," AIA Chief Economist Kermit Baker noted in the group's newsletter this fall.

Technology has continued to transform the home.

"Ten years ago, baby boomers didn't know how to program their VCR. Now they want computers, structured wiring, programmable thermostats and security systems," Steven Bomberger of Delaware-based Benchmark Homes said.

Americans also are getting comfortable with terms like low-VOC paint, sustainable flooring, home energy management and wireless telecommunication.

These are some of the trends of the past 10 years:

Living large

At the start of the 2000s, many jumped on the real estate thrill ride. McMansions, gobblers of space and energy dollars, became ubiquitous.

Now, people are rethinking how they live, said Jennifer Boles, founder of The Peak of Chic design blog and contributing editor to House Beautiful.

Oversize furniture like sectionals and big coffee tables, popular at the start of the decade, are being scaled down.

However, one oversize space remains popular.

"Spa baths have staying power," said Tampa-based kitchen and bath designer Jamie Goldberg. "They tie into several current trends: creating comfortable environments for aging, bringing back the luxuries of travel and spending more time in our homes."

Homegoods' Philip Tracey added, "The spa bathroom is the new two-car garage — a must-have if you ever want to sell your home."

Living al fresco

"The outdoor room's really been one of the biggest changes. Everyone has an outdoor space now, even if it's tiny," said Elle Decor's Cheminne Taylor-Smith. "With seating, dining, even kitchens and sleeping pieces, these rooms are treated like their indoor counterparts."

Fire pits, weather-resistant fabrics and furniture, and commercial quality heaters extend the outdoor season.

Living green

After a long fallow period, gardening took off in the past few years. From containers to victory gardens, people got their hands back in the dirt.

Renewed interest in environmental stewardship starts literally in the backyard. People are digging up the lawn and planting native greenery that requires little maintenance or water. Americans are putting down less pesticide, and more are composting.

People also started demanding paint and other home products that were enviro-friendly. Sustainably harvested wood became a selling feature. Many designers embraced the trend, providing beautiful art and furniture made of recycled materials. Now a kitchen counter might once have been a truckload of soda bottles, and solar panels can power everything from hot water heaters to patio lighting.

Living creatively

Americans are spending about $260 billion a year on home improvement projects, according to the Housing Industry Research Council. That is up about $90 billion from 2000. Empowered by informative blogs, magazines and TV shows, the DIY boom continues.

People are turning linen closets into offices, embellishing IKEA stock furniture and repurposing what already is owned in clever, practical ways. Designing on a dime, or close to it, has become a hobby.

With more creative freedom now to express personalities at home, the world became an inspirational marketplace. Global crafts found a wider audience. Mainstream stores brought decorative pieces from every corner of the planet to the doorstep, and design became more eclectic than ever before.

Living relaxed

Americans have loosened up. It's OK to have the computer and TV in the heart of the home. There has been a shift toward a more practical, casual lifestyle during the past decade.

As designer Mark Hampton says, "Real comfort, visual and physical, is vital to every room."

Suites of furniture? Passe. Untouchable formal rooms? Over. We're comfortable mixing and matching — a major shift from the '80s and '90s when people mostly picked one style for the whole home.

n Other hallmarks of the decade include: stainless steel appliances, granite counters, mid-century modern furniture, media furniture, Wi-Fi, home theaters, organics, Scandinavian design, Craftsman style, ottomans, wallpaper, cherry cabinetry, low profile home entertainment systems and less-is-more window treatments.
