Design Principles
In BETAPLAN we believe that the architectural design should be honest and comprehensible to its users, useful and unobtrusive, environmentally friendly and long-lasting. Moreover, it should respect and reflect the uniqueness of its surroundings, be innovative and at the same time aesthetically pleasing. Last but not least it should be expressed in a simple but thorough, down to the last detail, way.

Relationship with the client
Since the beginning the firm has had the chance to work for a diverse group of clients in both the Public and Private sector, ranging from Local Authorities to State Ministries and from small private investors to large institutions. Through the cumulative experience all these years, BETAPLAN can claim the ability to adapt easily and successfully to different situations and client requests which occur through the different phases of design and construction process. In BETAPLAN we highly value the relationship between the architect and the client and we believe that a major goal is the satisfaction of the client’s needs and ambitions. In order to achieve this goal we pursue from the very beginning to establish an active and honest relationship with our clients and we believe that only through close cooperation between the design team, our consultants and the client successful buildings are designed.

The Company's CEO is designated as the reference person in relation to this policy and the management of incidents of violence and harassment at work.

All queries relating to the implementation or interpretation of this policy are made to the reference person, who is responsible for and manages all matters relating to the information and counselling of staff, as well as matters relating to the prevention and management of violence and harassment at work. In addition, the reference person shall receive denunciations and/or complaints from the persons concerned about behavior involving violence or harassment, and shall deal with them as follows.

Complaints about conduct that constitutes a violation of this policy are accepted in writing at the dedicated email address, which is accessible only to the reference person.

Complaints are investigated by the reference person promptly and thoroughly, impartially and in compliance with the principles of confidentiality and protection of the personal data of the alleged victims and the accused.

In particular, the reference person collects and evaluates the complaint, recording and characterizing it. The reference person then contacts the complainant, informs him/her of the following options for managing the incident and asks him/her how he/she wishes to initiate the management process.

It is noted that complainants have the right to be informed of the receipt of their complaint and the progress of its examination.

To avoid worsening the position of the complainant, as well as to ensure the integrity of the investigation, the reference person must take all necessary measures, such as moving employees or modifying their working hours or the way they are provided (e.g. teleworking), until the investigation is completed.

In particular, following a complaint, the following procedures may be followed:

- Mediation of the reference person and reaching a settlement, through an invited discussion and a hearing of two parties. Provided the circumstances complained of have been resolved and the incident is deemed to have ended, with the procedure not taking more than 10 working days, the reference person shall prepare a report on the incident and its development and inform the Board of Directors of the Company.
- If the complainant does not wish to follow the above procedure, or if the above procedure is unsuccessful, the reference person shall draw up a relevant conclusion with the findings of his/her investigation with a simultaneous characterization of any observed behavior of violence or harassment and its degree, which shall be submitted within 10 working days from the receipt of the complaint to the Board of Directors, which is also competent to decide on the application of sanctions.
The Board of Directors of the Company, upon being informed of the reported incident of violence or harassment or discriminatory treatment, will decide on taking appropriate corrective measures and imposing disciplinary sanctions against the complainant, depending on the severity of the incident, which may include, but not limited to:

a. the oral or written reprimand or recommendation for compliance
b. a change of location, working hours, place or manner of performing the work
c. the termination of the employment contract with BETAPLAN or a cooperation agreement

Complaints that are proven to be manifestly unfounded or malicious will be filed as inadmissible, and in case the Company's management deems it necessary, they will be further investigated to restore order and avoid distortion of the purposes pursued by this policy.

This policy and the above procedure are applied in parallel and complementary to the general legislation in force for the protection of the employee's personality and do not affect the employee's legal rights under civil and criminal law.

The employee or senior staff who engages in such prohibited conduct bears full and exclusive responsibility for his/her actions and if the case follows the judicial route, the Company undertakes to cooperate with the Competent Authorities and to provide any relevant information upon request.

In general, the Company and the reference person appointed by the Company are committed to cooperate with any competent public, administrative or judicial authority, which, either on its own initiative or following a request by an affected person, within the scope of its competence, requests the provision of data or information and are committed to provide assistance and access to the data. To this end, any information they collect, in whatever form, shall be kept in a relevant file, subject to the provisions of the law on the protection of personal data.

At the end of the calendar year, a report shall be drawn up by the reference person with the incidents (without mentioning any persons by name), the type and evolution of the incidents managed.


BETAPLAN, during the last decades, has undertaken the architectural design from inception to completion, the design coordination, as well as the construction supervision of a wide range of projects of different size and nature, such as: Healthcare, Education, Heritage, Culture, Sports, Office and Government Buildings (Public Sector Buildings), Commercial and Industrial, Transport, Residential, Hospitality, as well as Environment and Urban Planning.

Since the beginning, our aspiration for the buildings we design, whether these are new Constructions, Conversions/Renovations of existing buildings, is to identify the unique challenges each project poses, in relation to their program and their surroundings.

One of the key services provided by BETAPLAN is also the correct interpretation and application of the local building codes, standards and European regulations throughout the design as well as the compliance of the design with the specific zoning ordinances and the preparation of the relevant documents.

Through BETAPLAN’s involvement in several of the major projects in Greece, like the Main Olympic Complex Venue of Santiago Calatrava, the New Acropolis Museum of Bernard Tschumi or the recently Stavros Niarchos Foundation Cultural Center of Renzo Piano Building Workshop, BETAPLAN, acting as the architect of records, has gained significant experience and is very familiar with the different permitting procedures depending on the type of the project. Specifically for the New Acropolis Museum and the Stavros Niarchos Foundation Cultural Center, BETAPLAN has been very actively involved in the preparation and follow-up of the ratification of the special Laws for these two projects.

Building Information Modeling (BIM)
In BETAPLAN we realize that in an increasingly globalized market, our tools must correspond to the requirements of international collaboration. Follow-up of the technological developments regarding software possibilities, drawing systems or product information is a strategic decision of BETAPLAN and by attending workshops, lectures and classes the personnel is able to respond fast to new and useful technologies. Building Information Modeling (BIM) software), and more particularly REVIT, is fully incorporated in the firm’s workflow providing an advanced way of controlling the quality of the designed buildings throughout the design and construction process.

Tender Documentation
BETAPLAN has also a very good experience in the preparation of tender documents and the follow up of the tendering procedure of big projects. Through recent international projects BETAPLAN has also very well familiarized with CSI Master Format 2010 for the compilation of the Technical Specifications.

Hangar C of the Hellenic Air Force, located within the area of the former Airport in Elliniko, has been declared a listed monument by the Hellenic Ministry of Culture, as it presents important elements of industrial architecture in Greece after the II World War.
The building complex with a total area of 4525m2, consists of two structures connected through two covered corridors: the main building, a metal arched structure built in 1950, with overall dimensions of 59.5m x 63m and a maximum height of 15.45m, and an existing auxiliary building of concrete structure, 3.60 meters high.
The study was elaborated in two phases,
1) The study for the restoration of the arched shell that included,
    a) Architectural and historical survey
    b) Pathology of the buildings (documentation of deterioration etc)
    c) Necessary works for the static adequacy of the building and shell restoration, aiming at the protection of the  monument and the highlighting of its original form. The proposed reversible works included the demolition of            added rough constructions that alter the original morphology of the building, repair and reinforcement of the             bearing structure, replacement of finishes, frames, coatings and roof insulation
2) The study for the interior layout arrangement to host the new temporary use as an information center and           exhibition space for The Ellinikon. The study aimed at highlighting the monument and secure public visits, so as     to be integrated in modern life.

COMPETITION AUTHORITY: Landkreis Bad Kissingen
3rd Prize

BETAPLAN won the 3rd prize for the design of the New Office Building Extension to the District Administration Building of Bad Kissingen. The New Building will house the District Administration’s Medical Services, General Administration Offices and a Conference Hall. The Gross Floor Area of the building is 1,839 m2.

The design objective is to achieve a simple and contemporary architectural solution that will blend harmoniously with the Old Town image of Bad Kissingen whilst fully satisfying all the requirements of a modern building.

The building has been designed as a simple, compact and free standing volume, with its boundaries being determined by the existing District Administration Buildings to the east and by the irregular shape of the Old Town to the west. The entrance is orientated towards the Town Hall Square and is defined by a recess of the building facade at that point.

The internal space organization results from the sub-division of the building into three distinct zones: the Atrium with natural light from the roof, the Concrete Core and the Office Perimeter. The public functions of the building and the public waiting areas are organized around the Atrium, whilst the non public functions are centered on the dark core.

The building shell, influenced by the chromatic palette of the Old Town, consists of colored exposed concrete in shades of orange and ochre. To reinforce the building’s mass and robustness, the colored concrete shell is continued on the 45 degree roof.

Cost Estimate: 4,500,000 €

The new Quality Control Laboratory Building will be erected next to the Company’s existing Main Building in Koropi of Peania, Attiki, with which it will be connected via a narrow bridge that serves exclusively as a channel for M&E installations. The new building will have a total floor area of approximately 1,780 m2 on 3 floors (Basement, Ground and First Floor) .

The Ground Floor will be primarily occupied by Laboratories and Quality Control, the 1st Floor as Offices and Conference Rooms, whilst M&E plant rooms and laboratory auxiliary spaces will be located in the Basement. The laboratory area is designed on a 1.15m modular grid, with which (in accordance with the pharmaceutical laboratory specialist consultant) an optimal arrangement of the workbenches and the circulation area around them can be achieved.

The same grid is applied to the facade design of the building. The facades will be cladded with terracotta tiles on a support metal frame, thus providing a ventilated façade. On all four facades of the building and at a short distance from the tile cladding, a system of ceramic vertical louvers, arranged in three graduating densities, will be installed in order to protect the windows from direct sunlight but also to achieve a consistency between the facades of the new and the existing building.

Al-Fedhailia Teaching General Hospital — Baghdad - Iraq, 2014-2016

The design concerns the Building Complex of the School of Social Sciences at the University of the Aegean on the island of Lesvos. The University site is located near the town of Mytilene on a green hillside with views towards the sea.
The new buildings will house the Research and Teaching Laboratories, the Teaching Rooms, the Teaching Staff offices and the School Library. The Building Complex has a gross built area of 5,623m2.
The central concept of the design is the harmonious integration of the Complex within the relatively steep inclined grounds of the site and the creation of outdoor rest and activity areas in the spaces between the building volumes.
The scheduled accommodation is developed in three independent wings, whilst circulation within the complex is achieved with a central spine of general circulation that connects the wings at all levels.
Regarding the external form of the building, the curved shape of the building volumes was designed to fit in with the slope of the site.
The outdoor landscaped spaces between the three wings can be used for a variety of activities, whilst they also function as reception areas, identifying thus the building entrances that are located in the volume of the central circulation spine.

Participation of BETAPLAN in a closed Architectural Competition after prequalification of 20 design teams. The site location of the project, at the foot of Brauhausberg hill and opposite the Potsdam Train Station is regarded as quite important as it contributes to the first impression of newcomers to the city.
The program was divided into 4 principal functions-zones: Sport Swimming Pool, Leisure Pool, Gym and Sauna with their respective open spaces. Through the incorporation of a central ramp that connects the two entrances of the building, the principal design idea is to intertwine the customer and visitor spaces in such a way that it is functional and inviting at the same time for all users of the building. The form of the building, inspired by the fluid nature of water, is curved and distinguishable from its surroundings as it befits to the special use and location of the project.
The competition included full architectural drawings at preliminary design stage.

Participation in open international competition

BETAPLAN participated in this Finnish competition with 544 entries from around the world. The competition included full architectural drawings at preliminary design stage. In terms of both the cityscape and its symbolic significance, the Central Library will be located in the very center of Helsinki, the Töölönlahti (“Töölö Bay”) area. The new building will form a cohesive totality with the Finnish Parliament building, Helsinki Music Centre, Finlandia Hall, Sanoma House and Kiasma Museum of Contemporary Art.
The defining concept of the proposed new Library is the creation of a homogeneous building without «rear facade», a building that is transformed at each floor depending on its function, its relationship to the surrounding area, the views and the orientation. The building's transformation is expressed on the varied outline of each floor level which constitutes the defining element of its mass. Homogeneity, in the appearance and form of the building, is achieved by the use of only two materials on its facades (wood and glass).
Program floor area: 10,000m2

Estimated construction cost: 69,900,000 EUR.
