You can sleep under the stars at these outdoor hotel suites in the Swiss Alps

If you're looking for creative ways to cool off this summer and like the idea of sleeping under the stars, you may want to consider a stint at one of Zero Real Estate's outdoor hotel suites in the Swiss Alps.

The Toggenburg project by Zero Real Estate, is based on an idea by artists Frank and Patrik Riklin, who have essentially taken three hotel rooms and dropped them into the middle of secluded Wildhaus, in Switzerland's picturesque Toggenburg region, for 45 days this year.

There’s the "Burst Suite" which sits above the Toggenburg valley at the foot of the Alpstein massif (pictured below).

And the “Schwendi Suite” above the Schwendiseen, a small lake above Wildhaus, as seen below.

And, finally the “Stump Suite” (pictured below) which is set under a canopy of trees, near Hotel Stump's Alpenrose.

Sadly the first two suites are fully booked for 2018, though there's still availability at the latter – the Stump Suite – which is conveniently located close to the hotel's wellness spa.

For CHF 295 (£228) per night, awaken to a "concerto of alpine birds" from the outdoor double bed. You'll also get a welcome drink, breakfast basket in bed, and your own personal butler for the night.

And fortunately the package also includes back-up accommodation in the event of bad weather.
