4x4 Mixed-Uses, conceived as a piece of "green urbanism" and hybrid architecture, represents a critical response to the need for sustainable and efficient urban infrastructures.

Through an analysis of the technical panels and the theoretical proposal, this intervention can be examined through the lens of social sculpture and climatic logisticsThe proposal is structured around the "Green Block" concept, a 140x140m model aimed at achieving a metabolic balance where $CO_2$ emissions tend toward zero. Architecture is understood not as an isolated object but as an integrated system optimizing the three pillars of sustainability: society, economy, and environment. The design utilizes a 7x7m structural grid that allows for total flexibility in space usage, facilitating transitions between studios, offices, housing, and commercial areas. This "tectonics" of local natural stone and reinforced white concrete acts not only as an elegant aesthetic choice but also as a thermal accumulator to reduce energy consumption.



The project incorporates advanced climate action strategies, such as the purification and recycling of water in open areas and the reforestation of public spaces with native vegetation. The building's morphology, combining perimeter blocks with towers, is designed to favor natural ventilation and filtered lighting, utilizing solar glass and photovoltaic panels that cooperate to power a low-carbon energy network. This "functional ecology" approach is complemented by a home automation network managing everything from air quality to automatic garden irrigation, allowing the building to behave as a living organism capable of reprogramming itself according to the needs of its inhabitants. In terms of density and social programming, the 4x4 / Russian Salad proposes a mixed fabric where urban life is activated across different strata. The ground floor is reserved for commerce and dining, while upper levels house a diversity of residential typologies and "Studios". This programmatic mix is essential to prevent urban desertification and ensure constant activity that improves the district's safety and vitality. The project positions itself as a "benchmarking" site for research tourism and urban development, where proximity to green systems and 100% public mobility defines a new standard for urban capital. Finally, economic viability is integrated into the architectural discourse through a detailed analysis of areas and $M^2$ costs, projecting an investment that seeks to maximize land value through certified sustainability. The building is classified as "Bioclimatic," incorporating cutting-edge technologies that ensure extreme efficiency in resource use. Ultimately, Anto Lloveras's project for this hybrid block is a lesson in applied "social sculpture," where architectural form serves as a support for a new ethics of coexistence and respect for the natural cycles of the urban environment.
