Fancy paddling on an unguarded rooftop? Or doing lengths in a structure cantilevered from a skyscraper? Following the popularity of yesterday's house with an infinity pool on the roof, here are some of the scariest swimming spots from Dezeen's architecture archives (+ slideshow).
This slate and corten-steel clad home in Stockholm features a concrete infinity pool on the upper deck with a large glazed opening cut into the side. The aquarium-like window is the first thing visitors see when they enter at ground floor level. Read more about this project »
Dutch architect Wiel Arets takes the aquarium concept that bit further in this swimming pool with large glass sections in the base, which cantilevers nine metres to the south west and weighs nearly 60,000 kilograms. People lounging on the terrace underneath enjoy both dappled light filtered through the water and a view of the undersides of swimmers passing overhead. Read more about this project »

Sky Condos by DCPP Arquitectos
For brave occupants who don't suffer from vertigo, DCPP Arquitectos proposed this 20-storey residential block in Lima, Peru, with cantilevered swimming pools that look like dividing boards sticking out of the building. There are no safety rails, for added excitement. Read more about this project »
It's the view from this floating pool that takes your breath away. Family and PlayLab first launched their plan to float a cross-shaped swimming pool in New York's polluted East River back in 2011. The +Pool will filter the water from the river through its walls to create a safe swimming environment, the architects say. Read more about this project »
