Some of the greatest challenges of the 21st century of human life include the isolation and the need to increase social interactions, depression, environmental pollution, high consumption of non-renewable energies, population density, huge amount of waste, lack of time, traffic, and work-life distances.
We propose a new model of hybrid architecture as a reactive, responsive, dynamic, and viable architecture, and contrary to the slogan of modern architecture: a building is a machine, we raise the slogan of: a building is alive. A building must be alive and must grow and evolve over time according to its foundation and environment. This results in sustainable architecture that can be problem solver.

       Hybrid buildings are the missing link between humans and the city, and bring people and urban together. This link will bring the social urban interactions into the hybrid buildings, where novel opportunities for humane expression of feelings and communication emerge through contrary functions.
