From the December/January 2009 issue, the L.A.-based headquarters of Entourage star Adrian Grenier’s green-lifestyle series Alter Eco, designed by Nathan Turner, looks totally relevant today with laid-back California style. We love his streamlined sofa, pedestal table (which is made from reclaimed tires), and brown and linen striped rug.

It’s only sensible that the creative director and president of J.Crew have an extensive and glamorous wardrobe, and the dressing room in Jenna Lyons’s Brooklyn brownstone, which was featured in the November 2008 issue, more than rises to the challenge. Her layered rugs are still on-trend today, and we admire her balance of rustic and glamorous pieces.

Swathed in Vivienne Westwood’s “Squiggle,” Agent Provocateur designer Serena Rees’s London townhouse is so fierce, it feels timeless. Certain accents like the Moroccan blanket and shag rug begin to feel dated, but on the whole, the room (which was featured in the February 2008 issue) maintains its statement-making style.

Decorated with the help of designer and friend Amy Kehoe of Nickey Kehoe, the home of actor Mark Ruffalo and his jewelry designer wife Sunrise Ruffalo, which was featured in the February 2009 issue, still feels totally relevant today. In particular, we’re still swooning over its T-shaped dining chairs (available at Nickey Kehoe) and 1970s Italian chandelier.

The rustic Upstate New York fisherman’s cottage of designer Thom Filicia, which was featured in the August 2008 issue, was designed with a nod to the ‘70s and appears timelessly referential and outdoorsy, as all lakehouses should. The decorative buoys and the faux taxidermy are the only slightly trendy decor pieces that feel out of place today, but otherwise we’ll take it as is!

We remember seeing designer Harriet Maxwell Macdonald’s transitional London apartment in the November 2007 and coveting its round built-in kitchen banquette. With its simple folding chairs and feminine-industrial cast-aluminum table, the little Euro-country nook is understated, homey, and spacious.

Temo Callahan, the legendary ‘80s and ‘90s creative director of fabric firm Clarence House, has been a design leader for long enough to know what’s timeless. The bedroom in his tiny New York apartment, featured in the November 2008 issue, certainly fits the bill with its classic red, white, and blue color palette and restrained mix of worldly finds.

Designer Michael Bargo’s spare Manhattan one-bedroom, featured in the March 2009 issue, is a fine example of the power of restraint and good editing. Though minimal and neutral, Bargo’s home has a few powerful pieces that make the space one of a kind.
