Casa Bosque is a project designed by Grizzo Studio. The plot on which the project was to be built was a portion of the garden of an old house located in the residential neighborhood of Martínez, San Isidro, a neighborhood characterized by an abundant presence of vegetation. Nature was, without a doubt, the host of the place, we wanted to be able to maintain the feeling of being inside that leafy garden on which we began to project, this was our premise when designing, enhancing the play of light and shadow proposed by the treetops that surround it.

Due to the not so extensive dimensions of the plot and the program of the house to be built, we did not have enough free land for the creation of large open spaces, therefore, it was decided that the project should function entirely as a garden, erasing the boundaries between the interior and the exterior, and making the house itself act as part of the exterior landscape. To achieve this, the walls of the house were designed with fluid organic shapes with textures and tones of tree bark so that walking through it is as if you were immersed in a forest. To achieve this, we developed exposed concrete pigmented in brown tones with brushed board formwork that, between the knots of the wood and the visual richness of the exposed concrete, give us that natural texture of bark and at the same time the nobility of the material that avoids future maintenance.
These organic structures are the support of the house and contrast with the smooth texture of gray concrete trays that are embedded in uneven ground and give the project the necessary orthogonality because it is a house between party walls. These slabs that seem to float on the curved partitions are at the same time the supports of the vegetation that at the top of the entire house allow nature to be brought to every corner and give life to these concrete trunks.
This is a house that allows itself to be colonized by the landscape until they become inseparable, that allows itself to be transformed by nature and the passage of time, until it is no longer possible to perceive where one begins and the other ends, as if it had always been there. The landscaping was designed in conjunction with the house as in all our projects.
As you walk through it, the house is divided in two by an internal cut that allows light and vegetation to enter all the rooms. Two large cylinders frame the entrance to a hall that connects the service staircase, the office, a circular toilet and the passage to a floating bridge in the center of a patio or to the main staircase that, together with other organic volumes on the upper floor, float over the patios, filtering the entry of light like treetops.
The house has a set of half levels (The entrance is at +1.50 allowing a garage to be incorporated at – 1.50), which allowed each room to vary its height according to its use and importance. The living room has a height of 4.50, allowing for light, cross ventilation and unique views.
The interweaving of straight and curved lines, inverted beams and the play of levels was a great structural challenge, as well as a 6-meter-long cantilever that manages to create the gallery without any corner support.
