Since the middle of the 19th century, the great European cities raised the need to transform their pre-industrial fabric. The case of Madrid, somewhat later, expands the city as a consequence of the population increase due to the agricultural crisis, which justified the expansion of the city by the bourgeoisie. The soil began to be understood as an element of wealth and commerce, houses were built using a marked and eclectic classic language as a desire for self-representation, and this language included, thanks to very permissive regulations, the construction of all kinds of viewpoints, cantilevers, Set back penthouses, towers and non-habitable domes, simply decorative. These spaces, used very often as storage rooms, are today the most appreciated for their exclusivity and representativeness, and the most valued for their terraces and views of all of Madrid. In the traditional neighborhood of Chamberí we find a huge dome 10 meters high that crowns a small squared space with two terraces on both sides, connected to the main floor on the lower level. A symmetrical house staggered in 3 heights that gives us the opportunity to carry out a comprehensive reform, where on the rectangular ground floor we will place the most public uses of kitchen / dining room / living room / in a single space, and behind a smooth and clean sliding door it It hides a Chinese cabinet that surprises with its dense decoration, and which in turn serves as a work space and a guest rom. Above the central space on the upper floor, the en-suite bedroom, crowned by the cupola, which can only be accessed by a delicate cat staircase made of corrugated pipe that climbs up to access a space of 10 meters height that has the power and beauty of being useless ... a space without a name, without use, a Follie, an extravagance, a useless, sublime luxury, where serious and conventional uses of the home have no place. Behind the bedroom, an unconventional bathroom of only 1 meter wide and 10 meters long, which correlatively includes all the functions that a space dedicated to the enjoyment of cleanliness and water can desire; the toilet with a reading area, decorated with a built-in staircase that the painters forgot and necessary to access the cabinets 4 meters high; the sink embedded in a lighted niche where you look handsome and powerful at the start of the day; a large shower / balcony that flies and jumps over the stairs, with views of the bedroom and the Sierra de Madrid; a sliding glass door that allows you to shower indoors in the morning sunlight or with the door open to the south-facing outside terrace; an outdoor shower to shower outdoors on those sunny days in Madrid from February to October; and finally an outdoor pool or bathtub with hot water and a solarium area for sunbathing. You cannot ask for more!!!! On the north terrace, the summer dining room, in the shade of the dome, a fully equipped outdoor kitchen and a large table to invite friends. 140 meters where you can enjoy alone or share and surprise with one of the best views of Madrid from one of its most iconic domes.
