In this project, architectural language is driven by algorithmic design approach to create a two-dimensional folded
plate structure with a set of design constraints and apply form-finding methods to sculpt it. The geometry is found by
manipulating certain parameters in accordance to the programmatic needs, building limitations and formal
expression.  For that, “Processing” was used as a form-steering tool (together with “Rhino” and “Grasshopper” and
library “punktiert”), the code was created and tested during the creative workshop “From Landscape to Roofscape”
together with Daniel Köhler and Rasa Navasaitytė. The use of computational tools proved to be crucial factor to
successfully implement the design proposal, providing it with geometrical order and physical logic.

The site is located just a few kilometers away from the central part of Sofia city, Bulgaria. It is limited by commercial area in the north and south-east, overlooking residential street in the west and marking the limit of the residential quarter “Mladost 3”. The projected site area is 22 000 sq. m., however only a half of this site is intended for possible building, the other half belongs to the city park territory and must be planed as a green recreational area. The new building is to become an attractive center of entertainment as well as the headquarters of “Walltopia”, the global leader in production of artificial climbing walls.

Urban situation
The surroundings


The project should not only create a new point of attractions to the “Walltopia” guests, but also provide engaging
public areas for the residents of the neighboring residential quarter. The project should also be eye catching from
different perspective angles: passing by a car (planned connection in the north), from nearby (the building internal
spaces and nearby outdoor spaces), and from a height (there are nearly two times higher buildings in a surrounding
area). Pragmatic USSR modernistic “bedroom” districts dominate in the context of the site, therefore the new
architectural solution should be both sensitive and unique, able to “wake” the social life of a neighboring block by
becoming a landmark building.

The conceptual focus in “Collider   ctivity Center” is the activation of building envelope while lessening the distinction between figure and ground. This objective is achieved by architectural pursuit to handle the plot area (both the landscape and the building) as harmoniously interacting whole, rather than establishing separate organizations within it. While the whole site area obeys to the rules of the same structural system, certain contextual factors (main connection lines, landscape, urban context) are affecting this structure in different ways. One of the most prominent constituents is the city park boundary, dividing the plot into two areas of different activities: park – calm, building -intensive. The interactions between the elements within the structure vary in those two parts dramatically, while the structure itself stays unified. This approach allows building volume to be “grown up” from the land surrounding it, and by doing that, a morphogenetic harmonious whole is being created between the landscape and the roof.

Lina Vestarte has graduated her bachelor’s in architecture at Vilnius Academy of Arts, Lithuania. During her studies
she has acquainted herself with algorithmic modelling strategies while participating in international workshops
organized by Studio Zaha Hadid graduates from University of Applied Arts Vienna. Lina later decided to pursue her
master’s degree by joining Center for Information Technology and Architecture (CITA Studio) at the Royal Danish
Academy of Fine Arts (KADK) in Copenhagen, further deepening her understanding in the use of digital technologies
and innovative methods in architectural design. Lina has extensive experience working within international teams in
various countries, such as COOP HIMMELB(L)AU office in Vienna (Austria), POLYFORM office in Copenhagen
(Denmark), PU-PA architects in Vilnius (Lithuania) and she considers computational tools as crucial constituents to her architectural practice.
