An Open Form Pavilion of Air is a floating roof of sound extending over a specific location, triggered by GPS and accessed via a smartphone, headphones and the echoes.xyz app. Inspired by Polish architects Oskar & Zofia Hansen’s “Open Form” architectural concept (ca. 1959), the Open Form Pavilion of Air series encompasses 15 locations in 9 countries, using sound and site-mapping to offer a playful renewal and reframing of public space as an essential place of engagement for the community. By walking through different zones forming this floating roof of sound using a mobile phone, the Echoes app and headphones, visitors become a participatory listener producing a composition in real-time. Their navigation creates a unique choreography via GPS, combining and changing sounds mapped through the app. Visitors hear the location and its context become transformed by the many sounds forming this floating acoustic architecture, revealing an immersive, profoundly spatial and physical experience. The Pavilion has no visible presence outside the app and can only be accessed and enjoyed on-site.

Approaches underlying Hansen’s pavilions using the logos of 'Open Form' architecture:
The Pavilions of Air parallel Hansen’s move to use the designs for the international fair pavilions as* “testing ground for designs that shifted focus from the object to ‘cognitive space’: to the individuals using them” – the modulation of the individual’s perception by the Pavilion of Air occurs at a variety of levels, among them the individual’s experience and apprehension of “space” ie location around them and its context. [* quote: Krzysztof Kosciuczuk - Frieze magazine]

Equally, as a spatial choreography through which listeners each move through on their own paths to compose their own piece through this movement, the Pavilion of Air echoes Hansen’s “pavilion for the Warsaw Autumn Music Festival (with Zofia Hansen, 1958) [which] were not only meant to expose the displayed products (or music in the case of the latter), but also turn the visitors into active participants and co-creators of their spatial experiences”. In the case of the Pavilion of Air the displayed content is the site over which the invisible roof rests without the material support of walls, only sound, air and imagination… [quote: Institute of the Present - Aleksandra Kedziorek]

Furthermore, as Hansen commented during the Team 10 meetings in 1960 “Open Form has the task of helping the individual find himself amid the collective, to make himself indispensable in the formation of his own environment,” – the Pavilion of Air aims to allow, produce or effect a realization within the individual that reframes their engagement with the location, the site and thereby society-at-large.

“It would seem that society should facilitate (and not impose, as Closed Form does) the development of the individual. There needs to be a synthesis between the objective, collective, social elements, and the subjective, individual elements.” Similarly the individual sound elements of the Pavilion of Air combine and are combined by the listener’s movement to produce a gestalt effect that facilitates this shift in site-perception.

Project background in previous sound/architectural works:
Open Form Pavilion of Air follows on from these previous selected architectural works:

- Climata (2015): recorded entirely in 15 of James Turrell’s skyspaces in 9 countries where each Skyspace was briefly transformed from an architectural light installation into a sound installation where you can hear the air move.
Climata was realized as an:

- SPECTRES (2019/20) - composed entirely of in-situ recordings with tone generators in 9 post-Communist architectures, it presents an interrogation of contemporary society across the threshold of the architecture from a former, but recent, epoch. SPECTRES was realized as an:

- Threshold Works No 17 (2021/22) – is a single 40minute multichannel work commissioned by the National Museum in Krakow (MNK) and permanent MNK collection acquisition. The work is presented as the entrance sound installation for MNK's permanent exhibition  ‘Sections: Gallery of Polish architecture of the 20th and 21st centuries’ ('Przekroje: Galeria Architektury Polskiej XX i XXI Wieku'). The installation was made using the resonances of the architecture of the bulidings of several branches of the MNK's buildings as a threshold, filter and frame for the city of Krakow, Watch an interview (in English and Polish) recorded at MNK's Hotel Cracovia branch about the project here.
