Under the name "Triptych" the building designed by Mariela Marchisio - Cristián Nanzer - Germán Margherit addresses a typological essay on densification in a degraded neighborhood area, Barrio Cofico, but with a strategic location concerning the services of the city center and the linear park of the Suquía River in Córdoba, Argentina.

The project is developed in a small and typical neighborhood plot between party walls, where the typological concept of the project is based on three vertical houses, not stacked but attached by their side boundaries.

In the project by Mariela Marchisio - Cristián Nanzer - Germán Margherit, the reinforced concrete structure determines both the expression of the building and the typological character of the complex. This fact is reflected in the segregation of uses that is given by the different levels, linked by the stair system of each unit.

The north façade is materialized through a metal structure closed with galvanized woven wire mesh, which is covered with deciduous vines, which arise from a continuous reinforced concrete box.

Description of project by Mariela Marchisio - Cristián Nanzer - Germán Margherit

The building is a micro-density trial of 3 houses/studios paired, on a conventional lot in the Ducasse neighbourhood, on the northern outskirts of the central area of the city of Córdoba, very close to the Suquía River and Las Heras Park, a traditionally commercial sector linked to the sale of spare parts and supplies for vehicles of all kinds, which today is in the midst of urban transformation.

The lot where the building is located is 10 m in front and 25.70 m in depth, that is to say, a small and typical neighbourhood plot between party walls. The typological concept of the project is based on three vertical houses, not stacked but attached to each other along their side boundaries, all with double ventilation, with collective garages, private patios and balconies and a terrace for communal recreation. The floors of the dwellings have a very small equivalent width of 3.13 m in their interior dimension, which is compensated by their large longitudinal development of 18 m.

The reinforced concrete structure determines both the width and the width of the building. The reinforced concrete structure determines both the expression of the building and the typological character of the whole, so that the segregation of uses is given by the different levels linked by the stair system of each unit, from zero to the terrace. The verticality of the typology makes it possible to dispense with interior dividers, which will be installed, if necessary, at the request of the users' needs, or with the incorporation of mobile equipment.

The project is conceived from the section, with an unusual layout for the logic of a conventional house, as the study/work space is located on the ground floor, in relation to the access to the building and to a small courtyard, which in some cases operates as a possible children's play area or sporadic barbecue area; on the second level is the space for two possible en suite bedrooms, but also adaptable as a place of work if the modality of use should require it. On the third level, with double height, is the living, kitchen and leisure space, with balconies and access to the upper terrace, which serves as the common courtyard of the complex, with the incentive of the views of the urban skyline of the city centre and to the west, the remoteness of the sierras.

Four longitudinal concrete partitions four levels high define the "bars" of the three vertical spaces of each unit. On the façade, an inverted beam with a span of 10 metres, from party wall to party wall, allows a sector of the 2 central partitions not to reach the ground, thus freeing up the space reserved for the 3 garages and the hall, creating an open space at the entrance; this space, when the vehicles are removed, becomes a space for sporadic social events for the inhabitants of the consortium.

The north façade is materialised with a metal structure enclosed with galvanised woven wire mesh, which is covered with deciduous vines, mainly wisteria, which grow out of a continuous reinforced concrete box, taking advantage of the inverted 10-metre-long beam of the façade. The whole building is a typological essay on densification in a degraded neighbourhood area, but with a strategic location in relation to the services of the city centre and the linear park of the Suquía river.

A building that does not deny some revisited Japanese precedents, such as the beautiful houses of Waro Kishi in Tokyo, but translated with South American eyes and hands.
