NEW YORK (AP) — That cute duckie wallpaper or nauticalfurniture set were great for your child’s baby years and just barely tolerable through elementary school, but a bedroom makeover is hard to get around when a child heads for the tumultuousteens.Consider the four C’s — classic, comfort, cool and color — when providing older kids with long-lasting lairs, er, lovely hangout-study spaces. And keep in mind a transformationdoesn’t have to mean tossing everything and buyingall new.Spending selectively now may just carry your child through the college years and beyond, to their first apartment,said design guru Nate Berkus, host of the syndicated"Nate Berkus Show."Jennifer Adams Meyers, an interior and home productsdesigner in Scottsdale, Ariz., said furniture in distressed,whitewashed and some darker woods are hot trends in baby furniture, boding well for use in a teen room through simple sanding and painting.Making a teen a partner in the re-design can be fun and fruitful, she said. "Let them have complete leeway. It gives them the motivationto keep it clean and organized,"Meyers said. "Give them a cork board and have them cut out 10 images they like."FURNIrniSHINhinGSA completely new set of furniture is probably not necessary,but a few items might be — a bigger bed, for instance.Another piece to considerinvesting in is a chest of drawers."Go for classic lines, not something too youthful," Berkus said. "Going with a vintage chest of drawers is a good idea, like English mahoganyor Swedish Painted. I’m more interested in peoplehaving something that’s an investment of a lifetime. How can I not have to replacesomething because I’ve bought into a theme?"Teens have different prioritiesthan little kids. They may not care much anymore about vast floor space to build Lego cities, for instance. Turn over some of that real estateto a couch and an overstuffedarmchair for reading, and to creating a hangout-study nook worthy of having friends over, even if it means going for a laptop desk for homework over a freestandingone.Bedside tables can be painted rather than tossed — and even double as desks, Meyers said. A lamp can be made new with a funky new fabric shade, and many home improvement stores carry beaded chandeliers in a varietyof colors. Consider keepinga rocking chair with a new seat cushion for a readingnook.Berkus is a big fan of vintage.He also had some suggestionson how to avoid spending money unnecessarily."The larger ticket items that I wouldn’t invest in would include wallpaper," he said. "That’s exclusively for a kid room. I wouldn’t invest in a rug. Go with stripes, black and white, blue and white, or gray and white."COLORolorThere’s no better way to let a tween or teen take control of their space than putting them in charge of palette, but be prepared to accept whatevercrazy color scheme they come up with.In addition to walls, linens can add a blast of color and texture. "It makes sense to let them pick," Berkus said. "They have a shelf life. They can only handle so many washes. Thematic is fine." Wall art is huge to many teens — a poster of a favorite sports star or horror movie. How about a collection of colorfulalbum covers from the ‘60s, a surfer scene, or framed memorabiliasuch as photos of friends and family mixed with your child’s own artwork and souvenirsfrom vacations? How about hanging skateboards or lacrosse sticks as art?Meyers suggested vinyl wall decals with quotes or special words ("Peace" or "Happiness") as a way for a teen to personalizethe room.Let them dress windows in wild designs and colors. Curtainscome funky and cheap these days, or buy inexpensive shades they can paint themselves.The idea is to cede some control, but not get thrown underthe bus altogether on style, design and cost.Chances are your little kid already had some throw pillows.Those can live on with new cases that accent the scheme. Teens read and study in strange positions, so a reading wedge or a body pillow that can be scrunched for comfort while working on a laptop would be a good addition.CLOSETS, SHELVES, CONTAINERSBig kids may be more attachedthan you think but too embarrassed to say that they’d like to display some of their growing-up stuff.In the new room, that baby chair collecting dust in the cornermight be more palatable with fresh paint covering the bears or ducks. The piece is saved but the nerd quotient diminished.Reserve shelf space for a favorite doll, toy and a few old books, but not front and center. Consider spacing mementoes between stacks of books, CDs or magazines. Offer storage in another room for anything else they might want to keep but not display.Berkus said ownership of the new space can be fostered in many ways."If your teenager really wants a specific item for their room, I like the idea of making them work for half of it, or comingup with something else they can do so they really understandthat pride of ownership," he said.Closets are a sticky issue. Big kids have bigger stuff, more clothes, more shoes, more sports equipment. Renovating a closet to make it deeper or wider may be unavoidable. Adding cubbies and a second hanging rod can help if expansion isn’t possible.Don’t forget to mount a full-length mirror on the back of a closet door. It’s a cheap, easy way to more quickly extract a teen girl from a bathroom. Extrapegs and hooks inside a closetcan be added easily and used for robes, backpacks, handbags and scarves.Looking to avoid dirty clothes as your child’s new decor? Let them pick out a full-size hamper with a lid to be stashed in a corner, rather than a closet, as a reminder it needs to get used.You know all those baskets and containers that caught the toys and baby books? Replace them with vertical book storage, graduating storage boxes than can be piled into a pyramid, or collapsible crates with handles that come in fun teen patterns and colors.
