The skin of the housing estate_regenerative transformation of the prefabricated housing estate, Devínska Nová Ves

Project idea

The project explores the future of housing in the panel housing estates of Bratislava. It examines the limits of the monofunctional structures of housing estates and the quality of the urban environment they provide in relation to changing housing standards compared to the period of their construction. It reflects on the life cycle of panel buildings, from the current extension of their lifespan through revitalization to possible future scenarios involving reconstruction, extensions, and structural degradation as part of the architectural program.
It investigates experimental approaches to the transformation of housing estates, focused on alternative extensions of residential functions within existing buildings and the addition of missing community-oriented and urban-forming functions. Panel buildings emerged abruptly and deteriorate just as abruptly; their decline here becomes a creative space for new architecture. The work combines natural processes of succession, patination, and curated degradation as creative tools for generating new compositional principles, new forms of utility in the context of the emerging environmental crisis, as well as new spatial layers within the housing estate.
The proposal responds to the climate crisis through the regenerative transformation of existing architecture, where the façade becomes a mediator between the building, the environment, and the community, while supporting ecological processes such as vegetative succession, moisture retention, and the creation of microclimates.
The aim is to create a scenario and forms of future housing, to seek an ecologically and socially sustainable response to the current challenges of the climate crisis, and to redefine the identity of panel housing estates.

Project description

The project originates from earlier research into abandoned rural houses and processes of natural degradation. This research revealed value in decaying structures and in the way natural processes colonise architectural surfaces. From this emerged the core idea of continuity between architecture and landscape, and the understanding that all built matter begins to transform immediately after construction.

A key conceptual analogy is drawn between natural and urban environments, where the colonisation of cracks in natural rock by roots is compared to similar processes occurring in urban masonry and prefabricated structures. In this view, housing estates function as urban cliffs that host specific ecosystems adapted to the city.

Natural processes such as biopatina, weathering, and ecological succession are not treated as degradation to be eliminated, but as productive forces shaping the environment. Primary succession becomes a central ecological model, understood as a long-term and predictable process of ecosystem formation on inert substrates. This process is visible in its earliest stages on prefabricated façades, where microorganisms and pioneer species begin to colonise surfaces.

This leads to the notion of curating degradation, where change, ageing, and ecological colonisation are treated as design tools rather than problems. Architecture is understood as a dynamic interface between living and non-living systems, constantly evolving over time.

The theoretical foundation is further developed through Stewart Brand’s concept of shearing layers, which describes buildings as systems composed of layers that change at different speeds: site, structure, skin, services, space plan, and stuff. The project focuses on the skin layer, which becomes an adaptive envelope capable of translating site-specific conditions into architectural form.

Methodologically, the project develops a dataspace based on mapping processes of degradation, geometries of decay, and ecological colonisation in the urban landscape. This analytical layer is complemented by ethnographic interviews conducted on housing estates, which revealed social isolation, a lack of communal spaces, and changing patterns of social interaction.

Based on this research, the façade is redefined as an active ecological and social interface that generates semi-public and communal exterior spaces. These spaces are integrated into the logic of the existing prefabricated housing structure and respond to the needs of the community.

The project is framed within a symbiocentric perspective, where humans are understood as one part of a broader ecological system rather than its dominant force. The façade supports ecological processes such as succession, water retention, and microclimate formation, while simultaneously enabling social interaction and collective use. Architecture thus becomes a mediator of relationships between humans, organisms, and landscape, where growth, decay, and transformation coexist as continuous processes.

Technical information

The proposal is based on the transformation of existing prefabricated housing structures in Devínska Nová Ves through the addition of a new external façade layer.

This layer is composed of modular façade segments derived from scanned geometries of degradation processes observed in the urban landscape. These geometries are digitally processed and further adapted according to environmental conditions such as orientation, solar exposure, prevailing wind direction, and local microclimatic factors.

The new façade system is structurally integrated with the existing building. Selected non-load-bearing elements, such as parapet panels, are removed, and a secondary structural layer is introduced. This new system functions as both self-supporting and anchored to the original prefabricated structure, ensuring overall stability and spatial rigidity.

The façade segments are differentiated according to environmental logic. Their depth, inclination, and morphology respond to solar orientation, prevailing wind, and exposure conditions. Wind is used as an active environmental input shaping the geometry, while the façade is designed to capture and retain material inputs from the environment such as moisture, airborne particles, and seeds. Local depressions and retention zones are introduced to support water accumulation and slow release.

Programmatically, the façade integrates ecological and social functions. The ecological layer is based on bioreceptive concrete and porous materials that support primary succession, enabling colonisation by microorganisms, mosses, and pioneer vegetation. The social layer generates semi-public and communal exterior spaces derived from the internal spatial logic of the prefabricated housing system, extending domestic life into the façade.

The spatial distribution of these interventions is informed by environmental analysis. Solar studies determine the placement of habitable and communal spaces, while western orientations and roof surfaces are primarily used for social and collective programmatic extensions.

The material system is based on bioreceptive concrete, functioning as an artificial rock substrate with controlled porosity. Its surface properties enable gradual ecological colonisation and long-term environmental transformation.

The façade operates across multiple ecological and spatial scales. At the microbial scale, porous surfaces support microorganisms. At the scale of mosses and low vegetation, cracks and retention structures enable growth. At the scale of small fauna, cavities provide sheltered habitats. At the human scale, the system generates inhabitable exterior extensions, balconies, and communal spaces.

Environmental forces are integrated into the design as active agents. Wind becomes a carrier of ecological information, while rainwater is captured, retained, and redistributed through the geometry of the façade system. Over time, the façade evolves through interaction with natural processes, forming a dynamic and adaptive architectural layer.

The result is a transformed prefabricated housing estate understood as a living ecological and social infrastructure, where the façade operates as an adaptive interface between architecture, landscape, and natural processes.
