Most Important Goals Projecting a unique building housing high-level ecological and bioclimatic-in a plot with a single facade, a warm tropical climate. Projecting a large glass (northwest) to frame a panoramic view of the extraordinary position of "The Rock" in Cali. However, the building should not overheat. Type of housing project a flexible and dynamic (with three bedrooms and two bathrooms), to a very high purchasing power. 2. Architectural Solution The site is located in a privileged area of ​​northern Cali (layer 5), with very significant growth prospects. The plot has a single facade facing west, which involves two issues: that the building will be exposed to tangential radiation every evening (for which there is no single architectural shading, and the sun has no direct view of the square "The Rock" (located to the northwest). To address both problems together, the proposed building setback away from the dividing north and has a huge glass cube with a great northwest. This glass is framed in a box architecture, as a sunscreen, and a movie has very effective sun protection. Thus, the building is not heated, and allowed great views. Additionally, setback allows the creation of a tiered system of terraces and gardens, which offer a high level of comfort for the occupants of the building. The building has five floors. The basement houses the garage, a shop floor and the top three floors house three luxury apartments. In the typological design of the apartments makes the most of available space, and create flexible spaces, controlled by sliding panels. The front holes are designed to enable the views and take advantage of cool breezes from the west of Cali. The apartments have a home automation control system that regulates the safety systems, telecommunications systems, motorized blinds and different lighting scenarios. 3. Eco-friendly materials 1.
