The pre-existing 1989 building is located at the front of the field, with north-south orientation. In its original state, this house had a couple of abandoned commercial premises on the ground floor and an unfortunate distribution in the rest of it. This led the architects to propose the new relocation of the program in 90% of the house, closing the spaces to the street, securing privacy, and opening them to the green area at the back of the field in order to communicate with this forgotten area.
The design of this home is developed from two premises; the first one to produce the space flow through the dense, prebuilt mass with specific demolition of some slabs and then create a triple height, and the second one to redirect the main house to the rear of the ground through the construction of a terrace that serves as a transition space.
The first major decision was to remove all existing excess elements in order to generate a volumetric value to the original construction. At the front the mega box purity was rescued with an ACM panel facade that boasts a design based on a pattern of rectangular openings that multiplies itself as needed for visibility, lighting, and ventilation inside the house. This double facade also generates thermal and acoustic insulation properties that make the project more sustainable.
The elevated terrace at the back of the house is in harmony with the original volume that consists of a series of high walls rotated 45 degrees, so that the volumetric addition copies and shimmers these breaks, generating a crystal crack between the terrace and the house. The other side of the terrace is entirely orthogonal to virtually complete the mega box.
The ground floor and the first level — both public areas — not only bind up by stairs but also by a ramp that goes from the back garden to the new terrace, allowing full access for wheelchairs, people with disabilities, and seniors.
The second level — private areas — contains the bedrooms which were turned around for privileged views toward the green backyard. Finally, the roof becomes a second terrace where the main protagonist is the sculptural domed structure in the middle of it. All serroteado coated finish was demolished and replaced by a simple flattened cement finish that helps to delineate the whimsical forms of the original construction.
