The 55-year-old Hotel Bel-Air will debut its new look this fall, as heap-big designers Alexandra Champilmaud and David Rockwell finish work on their collaborative redo of the storied Los Angeles inn.

After a full 24 months of renovations and refurbishments, the hotel is slated for an October 2011 opening, when all 103 of its newly decked-out guestrooms and suites (including 12 brand new ones) will be available for guests ready to dole out the $565-minimum per-night rate.

Said general manager Tim Lee, “We hope our new and returning guests will be comforted by our attention to detail in restoring the beloved iconic elements while adding contemporary touches that will elevate the guest experience.”

Among the features new to the old resort palace is a 12,000-square-foot mission-style pavilion containing special loft accommodations and amenities, including a full-service spa by swish Swiss beauty experts La Prairie. A new restaurant will also find a home on the Bel-Air campus, under the auspices of the inevitable Wolfgang Puck.

Word on the design from Rockwell/Champalimaud—a combo well-pitched to the Bel-Air’s reputation for old-style Hollywood glitz and glam—is that it will highlight “soft tones” in the public spaces, keeping in the spirit of the old building’s “Bel-Air pink” exterior. Likewise, the famous swans in the lake fronting the hotel, which have been circling blithely and undisturbed during the renovation, and who will now enjoy a new, energy-efficient water pump.
