Las Alcobas, a Luxury Collection Hotel by Starwood in California's Napa Valley, is expected to open in October 2015 once a multimillion renovation is complete.

The property is being transformed from the former Grandview Hotel & Spa into a 57-guestroom hotel which is owned and being developed by Spring Mountain Hotel – a joint venture between real estate development company Presidio Companies and Las Alcobas Hotel Group.

To be conceived by designer Yabu Pushelberg, the 3.4-acre property is a historic building called the Acacia House, which was originally a private residence in 1907 and converted into a hotel in 1911. The House will feature a 3,500sq ft (1,067sq m) spa, the hotel’s lobby, a signature restaurant, fitness centre and meeting space, including a grand ballroom and seven guestrooms – the others will be spread across the property’s cottages.

The St Helena City Council approved the historic preservation project last year. Georgian and Victorian architectural structures will be preserved.

Within walking distance of the Culinary Institute of America and numerous wineries, the property is in an ideal location for culture vultures.

“We are honoured to be part of the amazing community of St Helena, which is the epicentre and historic capital of North American winemaking,” said Samuel Leizorek, managing partner of Las Alcobas Hotel Group. “Las Alcobas, a Luxury Collection Hotel, is an accomplishment of many years of collaboration between the developers and the city of St Helena.”

“We look forward to the debut of Las Alcobas, one of three new Luxury Collection properties opening in North America in the next 18 months,” said Allison Reid, senior vice president of North American developments for Starwood.
