The proposal is organised along a linear axis that runs along the plot, cutting trhough the different building wings as a public promenade. The building is configured in wings that revolve around a central living space according to the typology of the atrium. The wings follow a spiral expansion around this central living space that is a clear design gesture of the proposal.

The proposal has the character of a loose, discontinuous configuration of apparently dispersed building units and lines. Yet, the design could be understood if it were imagined as a "ruin" of a former typical building in the same location. In accordance to this design gesture, access to the builoding is facilitated by a zig-zag promenade that gradually penetrates it. The visitor gradually explores the different dispersed parts of the proposed building complex as they walk along this promenade.

The elements taken into account in this proposal are: (a) the Municipality's wish for a building that uses passive energy efficiency systems and (b) the preservation of a prominent rocky ridge, which takes up a large part of the plot. The building is L-shaped with an inner multistoreyed central core placed between its two branches. Its glazed roof has external movable louvres for sun protection and makes use of solar energy. The natural rock is functionally and aesthetically integrated in the composition.

The apartments block has been constructed in terms of the typical Greek financing system of "antiparochi". The building includes a permanent sculpture exhibition on ground level and apartments of 80sqm each on the upper levels. Open spaces are configured in front of the built ones as a continuation of urban public space, thus allowing the building to embrace the living social space of the city and the adjacent "Syggros" park. The building follows the syntactic coherence of "base", "body" and "top" as it can be found in the modernist architecture of the 30's.

The dimensions of the site are such that enabled us to design, not a linear (a "bar"), but a spiral formation with an inner "atrium". The spiral movement of the building-mass evolves gradually upwards, gaining height. In its route it is followed (and underlined) by the parallel spiral "unwinding" of its metallic roof. The design makes use of polygnotic colours such as ocher or yellow, light or deep blue, and terra-cota brown.

We did not try to design a building which -in a way- would reproduce a child’s phantasy, just by exploiting the ingenuity of architectural form and its esthetic appeal. On the contrary, this functional daycare unit is also an introductory lesson about space syntax. And at the same time it is a friendly spatial game for its young inhabitants. It is the game of playing with architecture while living in it, in a special way that children know (and can) when architecture itself gives them the chance to do so. It is the building itself that makes the game possible. In essence, its design constitutes a series of basic architectural archetypes which join together as a functional and aesthetic «whole».

The building plan does not attempt to “correct” the awkward triangular shape of the site. Instead, it accepts and adopts this peculiarity and makes good use of it in a unique way. Therefore, it manifests itself along a triangular span as a spiral of wings embodying a linear open-space zone, and not as a mere blob. The essence of this dynamic is translated in spatial terms by the transition from the outside boundary along the National Road to the partly glazed atrium forming the inner core of the synthesis. This counter clockwise “penetration” towards the interior is visible at its start on the main façade along the National Road, as a vertical razor-sharp slit forming the high entrance to the walkway which divides the whole complex into two parts. In this way the elongated (running a total of 140 m.) main façade forms a local landmark perceived both during a slow on-foot approach and a speeding drive-by on the highway lasting a few seconds. The open walkway running through the synthesis is also an integral part of the design framework aiming at reducing energy consumption and improving working conditions within an uplifting spatial habitat.

The building complex accommodates an exceptional range of different functions including a theatre, a multi-purpose hall, an experimental theatre, a cinema, workshops, exhibition spaces, a museum, a library, shops, a conservatory, a day-care nursery etc. It fills a hollow facing South towards the Venetian wall and the monument to Kazantzakis. The centre of the composition is marked by an open-air public square, which is unified by a large semi-open metal shed: a multi-level multi-purpose nucleus.

The winding curvilinear configuration of the building takes advantage of the prominent longitudinal axis of the plot, avoiding the Western orientation by its twists and turns. The ground floor does not maintain the same arrangement as the upper ones, but it is arranged as individual cubic volumes that accommodate communal functions (eg. entrance, multipurpose hall etc.) detached from the central building volume. The facade towards the inner square is traversed by a continuous semi-openair passage that descends from the roof to the ground floor, and links the roof-garden to the cafeteria, at the same time becoming itself the linear unifying nucleus of the composition.

The complex is situated on a very “difficult” spot of the urban tissue, exactly were the curved borderline of the site directly faces the heavy traffic on the crossroad of the two main avenues of the city. We composed this part of the complex as an open receptor (a piazza), which is also the beginning of an open passage. It starts form the direction of the “Thessaloniki International Fair” territory and then goes on, facing the tower of the “Town Hall clock” (a prominent point of public reference). It then passes through the pilotis (where the two main entrances of the building are situated) and goes on following a zig-zag pattern towards the open inner core of the complex. At this point, it broadens, taking the form of an amphitheatric courtyard. Surpassing this area, the passage continues its route, leaving the Town-Hall and joining an existing pedestrian path throughout the neighboring park towards the dense urban territory beyond it. It is important to note that the zig-zag passage, while passing the inner courtyard, has a constant parallel correlation with the main Hall of the building. This central multi-functional meeting place has free visual contact with all the elevations, which surround it with their inner facades. Note the “difficult” unfolding geometric constitution of the roof and the rays of light infiltrating downwards from circular domes and slits placed on its surface.

Nominated for The European Union Prize for Contemporary Architecture – Mies van der Rohe Award 2013. Located under the hill of Filopappos, this house is an adaptation of the modernist concept of the “primary habitable box”, or the minimum “life container”. Instead of a design made by plates and free surfaces, hereby, the treatment of a solid “box” shape is prominent and adds to the building’s integration to the neighborhood. Despite the outer boundary that shelters the delicate intimacy of “private life”, the house retains a social façade, through a balanced visual and spatial intercourse between public and private.

Participation in international architectural competition 2007. The museum is conceived as an "active excavation site". The proposal consists of a "non-building", namely a spatial receptor that is already formulated by the natural landscape. The architectural intervention is minimized to the construction of a shed over the natural concavity. The roof resembles a hovering membrane in zigzag span located in a small distance over the ground. [:enteam] Architects: Tassos Biris, Aggelos Aggelou, Dimitris Papanikolaou, Sofia Tsiraki

The ascending or descending movement of the ramp (an open promenade along the major longitudinal axis of the building) attains a metaphorical meaning; Thus strongly referring to an «open chapter» (or «Avoin Luku» in Finnish). Or else, of a first «open chapter» and architectural comprehension of the library, as a complex articulation of spaces with distinct roles, relations and characteristics. Constant movement of the ramp is a strong sign of mobility: iIts zigzagging course, suspended in space, strongly differentiates it to the dominant horizontality of the neighboring buildings. It thus becomes a prominent symbolic sign of the Library, forming a distinct landmark within the city.

The design originates from the ground as its natural extension, through short concrete planted planes, creating a first, robust, chthonic receptor. A second one comes up, by timber frame construction, with proportionate inclined banks forming the central exhibition core for Argo. As a magnified spatial offset of the ship, the construction protectively surrounds it, and rises up above it. Thus, a landmark “non-building” with the sophisticated, fluid, non-Cartesian form of a “shuttle” is created, in correlation with the form of the ship in top view and elevation. The central space is adjoined with supplementary exhibitions and visitor facilities, while a multilevel perception of the ship is achieved through an upcoming course by a wooden mild ramp concluding at the café and the level of temporary exhibitions. On the axis of the Argo exhibition space, a multipurpose hall functions as a rest area with view of the ship, while it is proposed to plant a small “Dodonian” oak on top of it, as a mythic symbol.

Participation in international architectural competition 2015. The proposal is configured in wings around a central social space that has the typology of the atrium that is run across by a linear diagonal route followin the East-West directrion. The decisive spatial significance of the diagonal is emphasised by the flow of running water along the same direction and the local windlow. These two elements, the running water and the windflow, as well as the planted open-air central space contribute to the bioclimatic funtion of the Medical School. A promenade follows the interior facades of the wings along a spiral expansion around the atrium. This movement adds to the social and pedagogical function of the School as a space for gathering, communication and activity. [:enteam] Equal collaboration with K.

The concept configures a continuous upward and downward, winding and unwinding spiral motion, throughout the overall design. This motion complements the outline of the plot, and also establishes substantial connection of the New Cyprus Museum to the urban landscape of Nicosia and major public buildings in the area. The corpus of the Museum comprehensively follows this bilateral spiral expansion. The design configures a confined space for the outstanding Cypriot antiquities to be safely contained and exhibited, and at the same time gradually opens its inner space inviting the visitor to come in contact with these antiquities. It is a kind of basin which accommodates the exhibits with appropriate controlled light, and evenly occupying spaces above and below ground. In this way, the design significantly reduces the building mass projected on the surrounding urban landscape. Thus, an extensive open-air and lively public space is returned to the neighbourhood. The upward and downward motion of the building roof signifies a landmark that emerges from the ground and culminates in the pyramid light well. The roof configures an elevated archaeological promenade, a planted topography with open-air exhibitions and recreation areas above the Museum, which is thematically linked with the general sociocultural role of such a building within the Nicosia Cultural District.
