Swimmers braving a length of this pool will need a real head for heights - seeing as it's a staggering 38 storeys high.

The infinity pool will dramatically connect Sky Habitat Singapore's two towers once the ambitious project is completed in 2016.

With 509 apartments, the Moshe Safdie-designed development in the central island suburb of Bishan will offer residents stunning vistas across the area.

Flat owners will also be able to traverse the two structures via sky bridges on the 14th and 26th floors. Wong Heang Fine, CEO of CapitaLand Residential Singapore which is developing the site, said: 'With Sky Habitat, we are creating a habitat for the future; a condominium that is also a house.

'While structurally a high-rise apartment, Sky Habitat will give residents the feeling of living in a house. This is because of the natural ventilation, lush gardens, sky bridges and open walkways that surround them.

'At the same time, they will enjoy the luxurious facilities and the connectivity and convenience of living in one of the most popular residential estates in Singapore.

Safdie is no stranger to creating swimming pools in seemingly strange places. He also played a key part in designing the £4billio Marina Bay Sands development, also in Singapore, which has a 150metre pool 55 storeys up.

Worry: Hopefully there will be more health and safety in place around the pool once it is opened, as in this impression there seems to be no barrier over the edge

The boat-shaped SkyPark is perched atop the three towers that make up the world's most expensive hotel. The open-air pools are in stark contrast to NEMO 33, which with a depth of 33metres is one of the world's deepest.

The venue, in central Brussels, Belgium, contains 2.5million litres of non-chlorinated spring water and is usually reserved for scuba drivers to train in. And it is a tad smaller than the San Alfonso del Mar resort in Chile, where a quick dip could well turn into a marathon.

The world's largest pool cost $1billion, holds 66million gallons and is so big you can even sail boats on it.
