This design-research project aims to investigate sustainable solutions for key issues in the current architecture and construction system to address climate change. At the same time, propose a radically alternative possibility for the future of our society, where our buildings are living entities – biologically alive, physically intelligent, ecologically regenerative. The primary research questions were – what will it be made of? How will it grow? And what will be its form? And we attempted to answer these questions by driving research and innovations in three different frontiers – biochemical engineering, robotic fabrication, and digital computation. Each research domain has a specific output – a photosynthetic biomineralized engineered living material, an environmentally functional gradient system of fabrication and a situated emergent computational algorithm. The three outputs come together to create an integrated transdisciplinary system that can enable us to design living buildings. This interdisciplinary approach has been used to envision a proposal for an ecological-spiritual retreat in an abandoned silica quarry at Santa Engracia, Spain to regenerate the ecology that has been damaged by anthropogenic activities.

TRANSIENT TONES [programme] facade system for office building [location] London, UK [year] 2020 [project] academic | Design Specialisation studio [designers] Ahn S., Alalula D., Panagiotidou V. [software] Houdini, Rhino, Autodesk CFD, Grasshopper, Redshift, Photoshop, Illustrator
Transient tones is a project that was catalysed by the observation that the design of the existing built environment, specifically that of the transitional space between the enclosed and open space of build-ings and the relationship with the natural system surrounding it have remained restrained and clearly defined for over a century. Here this project proposes a spatial configuration for facades that hosts genetically modified, melanin-producing E.coli bacteria, consequently forming a light filtering structure that mainly protects from UV radiation. The envisioned design augments human senses, by introduc-ing an experimental performance of the structure in the homogenous modern space. A new sense of biophilia is explored through this co-existence with a synthetic life form and a responsive material palette that changes colour, shape and transparency levels, suggesting a new type of hybrid, semi-living architecture.

LANDING ON DUNES [programme] public building | airport terminal [location] Dubai, UAE [year] 2021 [project] academic competition | Environmental design competition [designer] personal work [software] Rhino, Grasshopper, Ladybug, Vray, Photoshop, Illustrator
This winning design competition proposal was inspired by airport terminals architecture and its recon-ception through environmentally conscious design. The developed pattern of the facade shading sys-tem was inspired by Al Sadu - the traditional weaving technique of Bedouin women. According to Unesco, the rapid economic development of the UAE has had a serious impact on the pastoral mode of life and the dispersion of Bedouin communities. There has been a rapid decline over the past few dec-ades in the numbers of women practising Al Sadu. There is an increasing need to safeguard the Al Sadu craft as an important part of the Emirati heritage, and the government is working together with NGOs to achieve that. The proposed terminal complex, in Dubai. UAE is a tribute and an architectural interpretation of that technique, and a terrain where traditional patterns meet novel design methods. The resulting facade pattern gradation is informed by solar radiation data.

REWIN[E] [programme] urban winery [location] Thessaloniki, Greece [year] 2018 [project] academic | design studio [designers] Panagiotidou V., Papadopoulos K., Theologi S. [software] Rhino, Vray, Photoshop, Illustrator
The goal of this design project was to revitalize a building in one ofthe city’s most vibrant areas. As only the framework of the eight-storey building is preserved, therefore the proposal focuses on a creative completion of the building by eliminating as less of the existing elements as possible. Inspired by the innovative thinking and complex architecture of Freie Universitaet Berlin, a fragmented, pixelated form resulted from diagrammatic studies and 3d investigations of the aforementioned building. The designed building hosts an urban winery, a novel usage in Greece, being simultaneously in accordance with the area of Ladadika. The starting point is the reconsideration of a winery’s building programme and all the needed spaces and additional uses, in an urban context. The basic aim was to transfer the usually horizontal-linear production line to a vertical arrangement as well as to expand it with uses and spaces for a broader audience. In a larger scale, the proposed building could highlight the end or the beginning of the broader existing network of wineries and wine roads.

NEW BELVEDERE [programme] public building | city theater + hall [location] Bruehl, Germany [year] 2017 [project] academic | Design Specialisation studio [designers] Fliegel H., Panagiotidou V. [software] Rhino, Vray, Photoshop, Illustrator
The following project regards an architectural proposal for a community centre with a theater stage of 200 people for the town of Bruehl, in Germany. The plot, which is close to a historical landmark and a park, had a lot of restrictions in terms of total coverage and use demands. We envisioned a versatile space that can host multiple events, and a walkable green roof, that acts as a vertical extension to the existing park. In that way, this public building remains vivid and open throughout the year and independently from the organised events. Traffic noise pollution is blocked by large music instrument installations that create corridors for play, wander and experimentation for the pedestrians.
