We like how A-Cero architects keep churning out hit after hit. Located in the Pozuelo de Alarcón suburb near Madrid, this magic mansion by them is the kind of stuff that dreams are built of. Their emphasis was on 3 simple principles - beauty, firmness and utility. And with these they have created a symphony of sculpture, earth and water.

The house includes a gym, cellar, music room as well as indoor and outdoor pools.
