THE people behind Thailand’s hottest property development have a clear idea of who will buy their luxury homes. “We don’t want anyone like Victoria Beckham, because that would bring in the paparazzi. The other residents wouldn’t like it,” says Harsh Roopchand, the director of Six Senses resorts and spas. “We expect our clients to be wealthy but low-key.”

High-rolling hedonists will be familiar with the Six Senses concept: the company is behind the Soneva and Evason resorts in the Maldives and Vietnam, and at other sites in Thailand. But its latest development, Soneva Kiri, which nestles in the rainforest on Koh Kood, a small island near the Cambodian border, is its first venture into selling properties.

“People who stayed at our resorts on a regular basis liked what we did and kept asking if they could buy a property for themselves,” says Sonu Shivdasani, the man behind Six Senses, who was at Oxford with the Tory leader David Cameron and still counts him as a friend.

Sonu and his Swedish wife Eva, a former model, put their names together for Soneva and Evason and now operate a hotel and spa empire that includes the Maldives destinations Soneva Fushi (a favourite with Madonna) and the spectacular Soneva Gili, where the best villa lets for £6,000 a night. The couple have come a long way from the days when Eva put talcum powder in Sonu’s hair so that bank managers would stop refusing him loans because he looked too young.

Sonu and Eva had already hoped to build villas for sale in the Maldives, but found the legal process too complicated and so bought a 150-acre plot of land in the Bay of Thailand. Getting to Soneva Kiri involves a flight from Bangkok to a little town called Trat and then a 45-minute ride in a speedboat, but Six Senses has bought land on a nearby island so that you will soon be able to fly in Soneva Kiri’s private plane direct from Bangkok.

Building work on the villas is well under way, with the largest and most expensive of the homes (£2.2 million) almost complete. Its design is distinctively Thai and the house is built of locally grown eucalyptus and makka wood, with bamboo cladding on the walls, and decking of New Zealand pine from managed forests. The emphasis here, as with all Soneva properties, is on eco-awareness mixed with luxury – to spoil the guests but not the environment. Energy-saving measures such as “grey water” systems and state-of-the-art glazing have been incorporated into the design. They also aim to cut carbon dioxide emissions to zero by 2010. The word “house” doesn’t do justice to the show home: it’s more of a tropical estate, a series of well-spaced rooms where guests won’t get on each other’s nerves. The buildings have a series of tented roofs that look like canvas but are actually a robust man-made fabric used on sports stadiums.

All the houses are large – from four to six bedrooms – and have at least an acre of land. The bedrooms have outdoor bathrooms with cylindrical showers created from recycled glass blocks. There will be a gym for each house, plus a yoga pavilion, sauna and spa suite for those essential Thai massages. The television room can be converted to a guest suite, so that you could accommodate 12-13 people in the largest house. A particularly nice feature is the Tree House suite for children, with bunk beds in knobbly wood and a slide from the balcony into the swimming pool.

Mike Sweet, the project manager, says: “We learnt a lot from building the other resorts, and we have developed a lot of green techniques, so we’re taking all the best features of those and putting them in here.”

The island is remote but has a good basic infrastructure – 30km (19 miles) of concrete roads, a small hospital, a police station (goodness knows what they do all day), electricity and water. It’s a low-density development and, because of the forest and the natural construction materials,the buildings are unobtrusive. When work is complete, there will be 36 villas (20 on the beach and 16 in the hills) ranging from £1.2 million to £2.2 million. Soneva Kiri will also be a conventional resort with 42 guest rooms (essentially smaller villas with pools), with three restaurants, a cinema built on stilts over the water, a spa and shops. In keeping with the eco-theme, transport around Soneva Kiri will be by electric golf cart or bicycle.

Owners can put their villas into the rental pool for a service charge of 16 per cent of the rental income, and they also get 20 per cent off their bill for restaurants, housekeeping, water sports and the use of a private chef. Foreigners cannot buy freehold property in Thailand, so that you can buy the fabric of your house at Soneva Kiri but not the land that it sits on. Instead, an offshore company is established in which villa owners hold controlling interests, with a Thai nominee as “owner”. You then take repeating leases from this company in tranches of 30 years, up to a quoted potential of 120 years – and possibly longer, though that’s never been tested in law. The legal process appears to be complicated, but in-house lawyers are available to reassure you.

Sonu expects that the buyers will be wealthy baby boomers whose preference is for homes in managed estates that are remote but accessible. There will also be a good international mix, with quotas being allocated to buyers from the UK, mainland Europe, India and the Middle East. The quota for Russian buyers is lower, on account of a few episodes of bad behaviour at existing resorts, such as demanding to be taken big-game fishing in protected waters.

Sonu reckons that this will be his best project yet, but he’s not sitting back: he is also looking to create eco-friendly resorts in Mexico, Belize, Panama and Guatemala. But what he is really looking forward to is showing off Soneva Kiri to his mother, who has a 20 per cent share in the business. “When I was at Oxford she used to scold me for not working hard enough and say: ‘You are a lazy bum!’ Now she says I work too hard. She doesn’t say she’s proud of me, that is not her way, but I know that deep down she is.”
