Paul Gauguin, Landscape with peacocks


A fairly limited area located in an arid region such as a desert, where the presence of water makes possible the growth of vegetation, and therefore a human settlement. A place, environment, condition or moment, that offers more pleasant conditions compared to those of their context or surroundings: green spaces are like resting oasis in highly populated urban areas.

O A S I architects is an emerging architecture practice founded in 2009 and constantly devoted to answer the daily life needs for individuals and communities. The name does not designate a signature or it does not presume an attitude.

Projects are developed through a careful perception towards the context where each project is based, not only geographical (place) but also in regard of the complexity of its conditions (client, budget, timing). Each work responds to specific needs emerging from this double sided context, never giving away, even if with very light interventions, to subtle artistic twists.

Research and observation play a fundamental role in the process of ideas, which is particularly focused on absorbing the experiences and the atmosphere of the cities and the surrounding landscape. Oasi stands on these values to define places, environments, conditions and moments capable of offering the best features in their existing context. 

Each project therefore potentially becomes an oasis.
