Changes of the organisational nucleus in Obregon & Valenzuela’s domestic architecture

The extensive quantity of projects that have been undertaken by the architects Obregón & Valenzuela include the design of a number of singlefamily houses. According to their own catalogue, ninety of these projects, mainly in Bogotá, were completed during the nineteen-fifties, fifty of which have been documented. This has been of great use in identifying persistent strategies for architectural concepts, which in turn lead to the creation of typologies. The fact that Obregón & Valenzuela assimilate both traditional and unknown models to develop the projects, and in doing so create new configuration typologies, gives the company a prominent position among modern Colombian architecture firms. Design features, such as changes in the organisational nucleus of the house, forms that cancel out volumes, or interactions between the parcel and the building, have influenced the behaviour of other contemporary firms, and have without doubt given a lesson to today’s generation of architects.
