Pixel Ecosystem

Segundo Premio Concurso Barcelona Capital Mundial de la Arquitectura 2026

(Festival internacional de Arquitectura de Barcelona) – Finalista



INFO

A green space folds up, climbing up the facades to meet the neighbours, who discover a particular garden in the middle of their homes, privileged views in spaces where before there was a wall appear, gaps that favour the thermal and spatial interior conditions open up.

Dwellings in a harmonious environment connected to the exterior landscape.


Two facades with the same constructive and architectural language face each other, marking the entrance to a new park in the city, creating a landmark visible from the Rambla de Badal, attracting people to this new found green space.


The original blind wall is reinforced and insulated to meet thermal and acoustic requirements, while the galleries function as a thermal buffer, where the vegetation not only filters the light but also generates cleaner air for the dwellings, as well as generating air flows inside the galleries.


(1) The project starts from understanding the structure of both original façades, which undergo a process of fragmentation or ¨pixelization¨, a matrix that identifies opportunities in the interior distributions to open up openings in the dwellings (rooms with views, living rooms with balconies, ventilation openings, etc).


(2) This matrix is transformed into a lightweight substructure anchored to the original structure, giving rise to the galleries, spaces to encourage human interaction with nature. The modular condition of these pixels allows the reconfiguration of these within the substructure according to possible future needs.

Meanwhile, on the ground floor, openings open outwards in the foyers, thus providing greater security to the public space.


(3) Within these “pixels” ecosystemic communities appear, that relate harmoniously with the vegetation, nests on the façade appear, allowing the relocation of protected birds. In these galleries, shrub species with a high C02 absorption capacity and low water demand are planted and, in the areas accessible via the balconies, the door is opened to the planting of edible species, in the manner of urban vegetable gardens. Spaces for multi-species cohabitation and natural synergies.

A FOLDED GARDEN

An extension of the green surface that generates a green walkway, at the service of the neighbours and the city. Façades that look out onto a new space providing it with light, security, clean air and attracting new protected species to cohabit the space.

(4) PRODUCTIVE FACADE

The percentage of photovoltaic panels required is more than doubled, integrated aesthetically with the design, generating a crown on the building itself and twisting individually in order to optimise the solar incidence on its surface. It is planned that this surface will be sufficient to provide electricity for the garden it faces at night, ensuring a completely sustainable, green and safe space.

Section

2nd Prize

¨The jury highlights the tectonic quality of the proposal composed in layers, in which the metal structure generates these “pixels” that allow the greenery and the solar panels to accommodated. The structure offers a lot of freedom for the owners to open windows, as it is an independent element of the part wall.¨
