h3_house in Athens Project Information

Located on a plot of 7000m2 the total area of the house is 1000m2.

The house was designed to give a sense of contact with the the water element inspired by the owners love for yachts. The contact of the house and the artificial ponds that surround it, create a cooling sensation.

The water for the lakes and the pool comes from a well, while the water demand for irrigation comes from a tank in which rainwater is collected through a drainage system. The sustainable design allows the sun to warm up the house during winter and and to protect the house from the sun during summer. The use of geothermal energy saves energy for the cooling and heating systems. The rooms are covered with spiral that in conjunction with the solar panels on the rear side of the plot, heat the pool water. Photovoltaic panels have been fitted at the rear side of the plot for the production of electric power.

H3 was constructed with eco-friendly materials and the interior furniture within the house, has been designed according to the needs of the owner. The design objective was to create a luxurious and ergonomic environment with clean lines and minimalist aesthetic. The surroundings of the building have been decorated with wall sculptures created by the sculptor John Aspras that give a tint of abstract to the house.

The architecture, the construction materials and the technologies, all contribute to the construction of this dynamic and contemporary house.Architect: 314 Architecture studio / Pavlos Chatziangelidis, Structural Design: Dimitris Arnelos and Maria Kazakou , Consultant Engineer: Fotini Karagianni, Construction: Mohamed Ahmed.

c29_Optimist Project Information

The optical shop C_29 / ’Optimist’, is an interwar listed building of a total surface 90m2 and is located in the centre of Chalkida.

The space is airy and expands along the central market and the back courtyard / patio which is formed in the core of the building. The building itself is a composite construction with the ground floor being made of bearing masonry and the two floors of reinforced concrete bearer and filling brickwork.

The main design aspect was the creation of a gradient technique in the texture of materiality in order to emphasize the reflection and the absorbance of light. This gradient tool continues to exist and plays a significant role even to the choice of materials, resulting in their sound existence or their theoretical absence in the formed space. Some utilitarian objects are transformed into prismatic sculptures.

The courtyard space is defined by an imaginary cube. What is more is that the plan does not allow visual contact to the courtyard and the shop. Therefore, there is formed a wall at an angle of 45 degrees in the intermediate space fully covered by mirror , which results in visual continuity between the two spaces.

H34 Project Information

The h_34 apartment block was awarded in 8th Greek Architecture Biennale. It is located in a 700m2 plot in Voula area 80m from the sea. The apartments have A+ ENERGY CLASS. They use their bioclimatic design and some eco technologies like geothermal energy, solar panel and rain water collecting systems in order to save energy. The architecture of the block is inspired from Japanese traditional architecture like the ‘’pagoda’’ and traditional Japanese ponds and vegetation. The design transforms the apartment block into an abstract contemporary sculpture.

h88 house in corfu Project Information

The studio is dealing with a refurbishment of a summer house on a cliff of the west of Corfu island in Greece. The land sets on a steep cliff covered in olive trees and surrounded by the sea. The house is located on the edge of a cliff like a lighthouse having a spectacular panoramic view of the Ionian Pelagos. The remote location of the house provides tranquillity and at night the absence of artificial light to the close area provides a tremendous view of the stars. Due to that the property will be called “The Midnight Stars”.Main goal of this refurbishment was a new design embracing Corfu's vernacular architecture transformed by a more contemporary design language. The introduction of the arch was the main component for its design. Due to the decomposition of the traditional typology and the rate of repetition of the arch element we created a minimal contemporary form. The plot expands to a 6 000 square meters area and the building is total 300 square meters. The studio tried to stay on these circumstances without affecting any of the natural environment.The main entrance located in the ground floor of the house leads to an open plan space surrounded by a series of arches making it an extrovert area with a monolithic composition. The living room along with the kitchen and dining room are located there. The existing columns are clad with mirrored panels in a triangular form. The original volume of the pillars is thus decomposed rendering it light weight and transparent as it also reflects the view and the surrounding landscape. We used natural materials as white cement plastered floors and walls, in a pattern that reminds a ruined stone wall. Outside the house the patio and the swimming pool are made by uncoated concrete. Facing the swimming pool there are the master bedroom and a guest room. The interior of the house was designed with curved ceilings and in this way the intersections of domes and arches created this contemporary design.

Leading to the upper level, the studio designed a more closed volume which allows the rest areas to have their privacy but always keeping in mind the orientation for the appreciation of the breath-taking views from the bedrooms towards the sunset.

H51 House in Muscat, Oman Project Information

The private house will be constructed in Seeb, a seaside suburb of Muscat. The 11.000 s.m. plot is inside a palm forest zone. The basic parameters of the design was the climate of the area with the high temperatures, and the social and cultural parameters of the islamic residential program.

The synthesis of the project was based on the transform of the parameters that provide privacy in the typical islamic house, so that the result would be a contemporary dynamic house. The climate adopting to the extreme parameters was archived with energy efficient technologies, with the saving and reuse of the rain water during the monsoons period and by the network of artificial lakes that surround the building and run through the ground floor.

c31 Enoteca di Salvatore Italian Restaurant Project Information

The restaurant is located in Zisimopoulou, one of the most commercial streets of Glyfada in Athens, Greece. The area's character is mainly formed by cafes and restaurants, therefore the Enoteca da Salvatore had to stand out of its surroundings. Main aim was to fulfil the needs of an all-day Italian restaurant, as well as, of an Italian cafe and of an Italian wine bar. Important aspects of the design were; the provision of adequate shading for the roof openings, along with the small interior space which had to host the kitchen, the bar and a number of tables. For the reasons above, a unified, non-closed space was introduced, with minor limits between the internal and the external. An indicative boundary is created by a light metal structure on the front space of the restaurant. Materials, such as, acrylic transparent sheets, thin ropes, light fabrics, glass, wood and metal are used to form the character of the facade. The low part, is composed of solid pieces of wood, which are attached on the metal frame. The middle one, consists of glass panels, that can be moved vertically in order to fully open all sides of the external space. The acrylic sheets form the top part of the facade. The relief surface of the sheets achieves a particular effect especially at night, where the radiation of the internal lights make the acrylic sheets to look self-luminous.

Finally the furniture attempts to express a more classic style related to the Renaissance and the Italian culture. In addition to this, a combination of Italian furniture with Greek materials is proposed. For instance, the Tinos marble is placed on the floor, on surfaces of the kitchen or the furniture, such as the round tables. High quality brass is applied for subtle and detailed finishings which add a more delicate philosophy to the whole space.

h65 _Teaser shot of house in Myconos island Project Information

The private residence is located in Myconos island. The total area of the house is 250m2 and it is divided into 4 suites. The design was inspired by the clearness and sculpture morphology of the cycladic architecture, transformed into a prismatic contemporary form. The residence stands on a prismatic rectangular base that creates a strong dialogue with the organic shape of the house and the curves of the landscape. It is seen from a birdseye view as a large art installation on the hill.

c45 Bfresh pavilion Project Information

This project is about a pavilion made for commercial use for a soft drinks’ company named “be fresh spitiko” that produces homemade juices.

The design concept was the transformation of an industrial era greenhouse. The transformation refers to the redesign of the greenhouse geometry using a more contemporary form keeping though the materiality and the essence of a classic greenhouse structure. The construction consists of a metal wireframe filled with glass panels.

Teaser shots of h71 House in Psychiko Project Information

Teaser shot of upcoming project H_71. The project is a renovation of an existing stone wall house in Paleo Psichiko in Athens. The total area of the house is 340m2. The main concept was to create a contemporary house that still keep the memory of the stone material. This is archived by the creation of a gradient in the walls that begin with the plaster covered stone and gradually transform into a contemporary origami pattern inspired by the traditional chinese sailboats. The center patio enhances the introversion of the new program of the house.

h33_Varkiza spa resort Project Information

This project is based on the client’s concept, which had the redefinition of the notion of ‘apartment building’, as its central axis. He redefines it as a vessel that can provide the user with a cultural and ecological environment, and one of social interaction. The building is located in a 4000m2 plot at the area of Varkiza and follows two basic synthetic axis that define the form, atmosphere and use of the spaces.

Firstly, by adopting abstract spaces that are surrounded by thick vegetation and ethnic elements, a residential environment is created, which provides the users with feelings of relaxation and wellness. A basic inspiration of the forms was the geometry of the sandstone rocks, curved by the sea.

The bioclimatic design of the building constituted the second basic synthetic axis, incorporating energy efficiency systems, such as photovoltaic panels and energy collectors, collecting waste water for secondary uses as well as the appropriate exploitation of the geometry of the forms. More specifically, the building is divided in three levels: basement (spa), ground floor (dwellings) and first floor (exclusive residences).

In the first floor, the residences are surrounded by a shell that reflects the 50% of suns radiation before it reaches the main thermal shell of the two residences. Those residences, also have access to the ground floors green roof. The sculptural forms that are evident in the level of the roof are used as skylights for the ground floor, and can also be used as abstract sculptural seating’s for the roof area.

At the ground floor level, smaller scale airy residences are reaching towards a central main atrium, a space characterized with sculptural elements and thick vegetation. A business centre and one shared kitchen-restaurant that hosts biological cuisine cooking seminars, form the spatial configuration of this level and add a semi-public character in the meeting spaces in between. Every residence own a private swimming pool. A significant amount of emphasis was given during the design process, in order to attain the maximum level of privacy.

A cyclical ramp in the atrium space enhances the movement, reaching the basements atrium towards the lower level. This layout, provides vertical lighting towards the spa spaces as well as the heated public pool that exists in this level. This space is surrounded by water therapies uses, Jacuzzi, hammam, massage and a beauty centre. Secondary spaces and the garage of the building are also located in the basement.

An outdoor space adjacent to the building hosts a spherical greenhouse and other various outdoor activities, such as cinema, art seminars and biological cultivation, take place. The proposed building materials are natural, such as perforated wooden panels, cement mortar, exposed concrete and black bamboo.

h15_house in Lagonisi Project Information

The h15 house is located in a 700m2 plot near the sae in Lagonisi. The house area is 260m2. The house has A+ ENERGY CLASS. It uses its bioclimatic design and some eco technologies like geothermal energy, solar panel and rain water collecting systems in order to save energy. The dynamic form of the residence also works as a bioclimatic parameter as it protects from the north winds blow strong in this area and also uses with efficiency the sun. The h15 will use eco-friendly materials and the interior furniture within the house will be designed according to the needs of the owner.

p12_Proposition for Archaeological Museum of PIraeus Project Information

Our survey identified two points at the program that negates the study. Kanari str. cuts the effective communication of the site with the new museum. By degrading it , we achieve the absolute and consistent unification of the two sites, and their programs. The second point, which our survey identified as a problem, is the location and volume of the existing building. On the one hand the volume is of disproportionate scale of the urban front, that is located behind the intervention area.

On the other hand the very close proximity from the front creates lighting and viewing problems. In the context of this concern the demolition of the existing building was decided (either way a substantial interference with the existing structure would be too costly).The triangular shape of the proposed new building for the offices and the warehouses with the new position - at remote from the boundary of the rear neighborhood improves the natural lighting and ventilation, while at the same time enables the view to the sea. The shape and orientation of the building enhances the natural light inside, as the light enters from all 3 sides-south, east and west.

Moreover, the curves on the roof of the new building resemble the rippling sea and contribute to the collection of rainwater through a water management system. So associatively the building with the port, while it establishes a new landmark for the city of Piraeus. The new museum occupies an underground level, thus creating a direct reference to the idea of the archaelogical excavation. The visitor is invited to submerge into the landscape through a ramp a to enter a buried, ancient world.

The overlapping landscape is folding to accommodate for the restaurant and the multi purpose hall, while serving as a connecting surface between the plot itself, the archaelogical site and the adjoining neighbourhood. Part of the landscape is planted, creating a public green space while the rest utilizes coarser textures, directly referring to the Ietionian gate archaeological site.

The building includes : showrooms for permanent and temporary exhibitions, venues for educational programs, offices, guest service areas, a restaurant, an amphitheatre, and other assistant rooms.

exploring the boundaries Project Information

1st prize in architecture competition Exploring the boundaries. Multiprogramming project in Mesologi lagoon. The project is located in the existing artificial salt lake in the Mesologi lagoon. The salt factory in Mesologi city, is the biggest in Greece and has some controversial ecological impact in the ‘’Ramsar’’ protected salt lake. Our proposition includes facilities for ecological research, protection of the lagoon and ecotourism that would give founds to the city of Mesologi and to the research institute.

bombing rooms Marocco Project Information

The design proposal concerns the Architecture Competition for the "Casablanca Bombing Rooms" on a highly charged site due to a bombing act in 2003. The project highlights the need for alteration and public communication and uses knowledge as the key feature.

“Chrysalis” aims to make a gradual transition from unawareness to knowledge as an attempt of elimination of any act of violence. This transition is achieved through a movement that emerges from darkness, penetrates a water layer as a sign of purification and results to the light.

The visitor follows a narrated promenade on a rising helix ramp that begins from the exhibition area underground and goes on as a journey of knowledge. The ramp is wrapped by a cloth shell producing an aerial and organic form leaving a humble imprint to the city of Casablanca. The light materiality contributes to that direction. The promenade is interrupted by several intermediate levels. A second cloth shell surrounds the levels creating semi-outdoor spaces that host the conference room, the classrooms, the administration offices. The public space, that includes the main library, is transferred to the upper levels (agora) where people gather, study, communicate and interact with each other.

The building works in an energy efficient way due to a geothermic system that uses the stable temperature and the thermal capacity of the subsoil. A water tank in a depth of 10m into the subsoil works as a cold capacitor keeping a stable 16oC temperature. A turbine is placed above the water tank and revolves in a slow rate. Due to the sub-pressure in the surface of the water that occurs from the turbine, the air frigidity is propelled through the building. Finally the warm air escapes from the top of the building resulting to an air renewal and thus a natural air circulation.

Venice Biennale of Architecture Project Information

We are facing one of the biggest humanitarian crises of the 21st century. In this context Greece is the main receptor of refugees, the first shelter for people who are forced to abandon their homes, the first stop in their difficult journey. Europe is obliged to respond to the refugee issue with an analogical distribution of refugees among all the Member-States, in order to relieve the host countries (Greece, Italy, Spain) from the huge responsibility of catering for the safety and the needs of each and every refugee arriving every day, by employing the European institutions and collective forces. There is no doubt that no country can manage individually an enormous crisis like the current one, which has been affecting the Mediterranean area the last 5 years.

The physical object proposed will illustrate and simultaneously serve as a non-verbal comment on the present situation. The European area will be presented as a landscape with a variety of different altitudes. The higher points represent the countries with the more intense refugee and immigrant flow in Southern Europe. What is inferred from the landscape is that in the area of Southern Europe has been created a new one, the ‘new site of Europe’. Based on the data of UNHCR concerning the refugee flows, a new background has been proposed which indicates the need for the flows to spread across the European area as a whole. That gesture shows the crucial need for the refugees to obtain the actually required space, while, as per the architectural proposals, it appears that a new field of research and a new site of creation is bound to emerge.

p02_house in Gazi Project Information

The P_2 private residence in Gazi is located in the center of Athens. The P_2 is an academic workshop experiment on the way that we are able to use the space in small dense urban plots. It is a two floor house with a side veranda that is located by the green vegetation wall, and a ground floor pool with mechanical underground parking.


Pavlos Chatziangelidis founded 314 architecture studio in 2004. He studied civil engineering in National Technical University of Athens 1996-2002 and architecture engineering in The University of Thessaly 2006-2012. In 2004 he acquired a Master of Arts degree in design. The name 314 of the studio, is inspired from the mathematic symbol π = 3,14 that is used to count the area of the circle. This reference is related to the philosophical dimension of the concept of the circle. The basic characteristic of his design beside the ecological, social and programmatic dimensions of the project, is the creation of a shell that urges the user to experience an abstraction.
