'What is luxury?' Sonu Shivdasani (pictured below), the founder of Six Senses Resorts and Spas, asked on Tuesday night. Considering that he was standing in The Peninsula's garden suite, with three expensive 19th-century Impressionist paintings hanging on the wall, and about to make a sales pitch for some pricey private resorts in Thailand to an affluent crowd sipping champagne, that question is downright existential. The Bangkok-based developer was in town to promote his (and his Swedish designer wife Eva's) private residences on a pristine island accessible only by a private plane 50 minutes from Bangkok called Soneva Kiri - about half of the 20 villas are apparently snapped up already by mega-rich buyers. However, as the environmentally and socially conscious resort builder suggests, living it up doesn't necessarily mean living large. 'It's about intelligent luxury,' Shivdasani preached. 'It can come from different contexts. Even something as basic as fresh air is a luxury if you live in a big city.' We're not sure how many of the cocktail regulars were as interested in eco-organic-sustainable living as the idea of grabbing their own island paradise. As for the Edgar Degas, Camille Pissarro and Claude Monet paintings on display, they were on loan from Christie's ahead of its auction next month in New York. Oh, the dilemma: does one spend one's millions on a Six Senses villa or try to land the Monet under the hammer?
