The second phase of the project for our client MAKRO in the central Paseo Imperial to house the company’s head office in Spain and Portugal has been completed. This central office has been conceptually developed around three principles for the German company: simplicity, sustainability and versatile, participatory design. The overall result has generated an environmentally-friendly smart building integrated into its surroundings. This is how we see sustainable architecture: as the integration of the construction, technology and energy supply systems.
