Interestingly, many of these 12 pools are in warmer spots, but play with the idea of blending indoor and outdoor space.

Chicago area firm New Space Architects designed this sleek white contemporary residence, with a pool that slices through it. Though it looks to be outdoors, if you look up, you’ll see it’s covered by a glass skylight. Two glass catwalks cross over the pool, and plenty of glass railings keep the space crystal clear.

Palais Rasumofsky was built for the former Russian ambassador under Czar Alexander during the time of the Viennese Congress of 1806.

The concrete wall lends a modern feel to the simple indoor pool.
