The major renovation of the existing hotel upgraded the appearance, the value and the quality of the property.

The building complex consists of one main 5-floor building which expands in three wings, 18 doublefloor bungalows, 14 single-floor bungalows and 6 units dedicated to complementary uses. The structural system of the entire complex is maintained and reinforced while the appearance and the design is improved to a contemporary yet diachronic fashion.

The magnificent natural environment is kept intact to the extent possible and it is enriched with regional plants. Stone from Lakoma Chalkidiki and locally produced marble shape the character of the complex and define major separations among rooms and uses.

Common use spaces are discreetly distinguished from the private with semi-private intermittent spaces and with the gradation of pavement and landscape materials.

The project design was completed under a tight schedule and it was successfully delivered on the agreed time.

The site is at the northern part of Samothrace island in north Greece, at a remarkably vegetated area. The character of the region is shaped by the island’s wellknown waterfalls, which begin at the mountaintop and continue to the sea. The main concept of the site development is based on the idea of an artificial river that passes throughout the site following a closed, water recycling system. This waterway echoes the aquatic richness which gives the island of Samothrace its identity. The main building is located on the northern part, with easy access to the central road of the island. The main lobby leads to the rooms and to facilities such as a Bar, a Restaurant, a Library, Shops, an indoor Swimming Pool with a Gym and a Multipurpose Space. The bungalow suites are located on the southern part offering privacy to the rooms.

Outdoor spa facilities, a basketball court, an outdoor playground, a small amphitheatre and a swimming pool are located around the main building.

The “WHY house” is a critical response to a call for affordable, low-energy, single-family homes for the communities of New Orleans Louisiana long after the devastating impact of Hurricane Katrina in 2005.

Such call required that the post-Katrina building codes should be met while the design should adhere to the Passivhaus Standard objectives, The proposed house is questioning the brief and the implementation of a Passivhaus in a subtropical climate. It aims to achieve a more flexible and adaptable design which would be more financially and environmentally efficient following passive design strategies. Taking the post-Katrina example in NOLA as the necessary background the “WHY house” is aiming to reveal the current conception of sustainable design and dwelling in the current context of the US. It is suggesting a less robust design approach, as opposed to the mainstream perception of what sustainable construction methodologies consist of. The design process of the “WHY house” explores form-finding and materiality specification of a single-family house, their effect on the thermal and visual comfort ranges within the building while adhering to post-Katrina code restrictions. Heat dissipation, optimized heat balance, solar control and the enhancement of natural ventilation patterns are some of the environmentally related issues studied and applied onto the design itself.

IN BETWEEN is a low-energy single family house conceived through its transitional elements serving the building functionally and thermally. Its layout clearly identifies the “private” from the “public” spaces and is takes full advantage from its south orientation.

Secondary uses and circulation areas buffer the north part of the house while the east part is buffered by the garage space. An incorporated office space minimizes the need to leave the house during extreme weather.

The open space layout and the central location of internal heat sources (kitchen, fireplace) help with the distribution of heat gains more evenly. The efficiency of the envelope dictates optimized insulation levels following Swedish standards (as required) as well as enhanced air-tightness through careful detailing.

A double-window system is designed to further mitigate the overall heat losses of the house by using a preheated air ventilation system. Embedded movable wooden louvres match the wooden finished skin of the building, resulting in a kinetic facade that can dynamically become more or less porous according to the external climatic conditions.

The ECOnnect school proposal addresses the question of whether the building could establish a dialogue with the environmental and vernacular features of the local Cretan architectural heritage while responding to the needs of a contemporary educational facility characterized by young students coming from diverse cultures. In order to respond to this challenge, an environmentally responsive strategy was devised: the incorporation of passive design parameters define the process of form finding, the functional relationships between spaces, the optimization of building performance and the visual tectonics of the building.

The scheme features spaces for a Kindergarten, a Primary School & a Secondary School as well as Administration and Common Use/Multipurpose areas.

However, the use of archetypal forms of Minoan Architecture, namely “the Main Court” and the “Stoa” (walkway), act as a regulating aspect of the scheme while the use of environmental simulation tools diagrammed the proper size, orientation and fenestration of the resulting spaces. Thus, the strategies range from the optimization of the classrooms’ orientation (due north-south), the optimization of daylight availability in the classrooms through narrow spaces and lightshelves; the implementation of indirect passive solar heating through preheated sunspaces in winter; and the use of enhanced stack and cross ventilation and multiple-mode optimized shading devices for the warmer months.

At The Edge is a proposal for an elementary school which focuses on the location specifics and the existing built elements. The earth formations with the steep slope, the unique flora and vegetation and the potential of the existing structures to be adopted by the new design drive the architectural concept.

The school’s building complex stands in a notable position within the urban network of Thessaloniki, in close contact with the suburban forest, with an astonishing view to the cityscape. Its concept is thus aiming to encourage contact with nature and environmental awareness.

The building is divided into three main volumes in order to naturally follow the slope of the terrain and, in this way, offer sufficient daylight, natural cross ventilation and views to the city for most of the classrooms and other communal areas. By scattering the building complex across the site, the existing trees are maintained. An open tower with a stairwell and an elevator serves as the vertical connector for the building complex which is layered in six levels.

The school’s design adopts the principles of environmental design for a Mediterranean climate, reducing energy costs to a minimum and offering a pleasant and healthy environment for users and visitors.

MULTIPURPOSE SPACE AND GYM The multipurpose space and the gym are accomodated by the same transformable space, which can host events, seminars and sport activities accordingly. The transformation of the space is a low-cost, lowtime process that can be realised by non expert personel. When the seats are unfolded, the space can accomodate 150 people and the stage is designed for small musical or theatrical events. In support to such events, there is backstage spaces designed in two floors. The wall finish materials are absorptive and the ceiling is shaped according to the acoustic design requirements. The main entrance is located at the upper level of the seats and the alongated balcony functions in support to the events that take place. When the seats are folded and stored in the space provided at the back, the entire surface functions as a closed gym and the entrance is at the lower level. The roof is then folding on top in order to allow for daylight from the clerestories and the balcony can host additional audience.

The city of Thessaloniki, apart from being a palimpsest of architectural features embedded in a network of urban discontinuities, it is also a space that has been occupied by people who are not present today.

The core idea of Silent Crowd is the orchestration of the different symbolisms of the historical center of Thessaloniki, this time at the level of the history of people that have occupied the city.

The square is imaginably divided into two functional natures: In the three sides where the urban facades appear, the osmosis with the cityscape is aimed, while in the micro-scale, hard surfaces and extroverted uses are engaged. At the places where the square starts meeting the sea, the hard surfaces are abandoned and the plantings engage in the dominance of the natural soil. A gradual change of materials is created around the square, allowing its core to accommodate the transmission of various meanings. The resulting excavation is covered with cast soil which hosts the traces of an event that took place 70 years ago and represents the last massive presence of Jews population in Thessaloniki. The use of lights at ground level reproducing the relationship of the void and the full between the crowd and the square. The whole surface takes the shape of a rift in the city, serving as an interruption of the urban landscape in order to dedicate its interior to urban memory.

The design of the covered waiting area addresses the dual nature of the project: time and space. Space is understood as the intermittent area that forms the necessary predicament in order to communicate with the surrounding area, which stands in the center of the design as the main source of inspiration. Time is understood through its temporary nature on the journey of the subject and there is value assigned to the otherwise “blank� waiting time.

The design draws inspiration by the presence of the emblematic Castle of Chios and the composition of the embrasures. The embrasures are characterized by the sequence of the complete and the blank, the action and the reaction, the visible and the invisible. By using this sequence as a design tool, STASI is responding to the main requirements of a waiting area: shading and weather protection, accessibility, interaction with the urban life.
