The project involves the transformation of a 450 sq m single-family residence, located in the Alto de Pinheiros neighborhood in São Paulo, into five autonomous residential units, each ranging from 60 to 100 sq m of built area. The aim is to ensure that the new units preserve the character of a house, always incorporating outdoor areas that extend and integrate with the interior spaces.

The proposal is to create a residential courtyard (villa), with shared spaces including circulation paths, gardens, and parking for cars and bicycles, as well as private gardens and terraces for each unit. The transformation reinterprets the original house, adapting it to contemporary demands without significantly altering its built area. This reflects a current urban trend of reevaluating land use and density without necessarily resorting to new construction.

The design concept centers around working with the pre-existing structure, preserving and updating the aesthetics of the original building. The masonry walls, glass bricks, and clay tile roof from the original residence are retained and placed in dialogue with the new architectural interventions.

To preserve the physical characteristics of the main existing building, all infrastructure support for the complex has been concentrated in a newly constructed volume located at the rear of the lot. This new block houses one of the residential units and a technical slab that supports the operational needs of the complex. 

The use of similar materials between the new and existing constructions reinforces the continuity of the architectural language, resulting in a set of units with equal aesthetic and functional quality, without hierarchy among them.
