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.

Quality Assurance
One of the most important aspects of BETAPLAN’s quality policy is the Organizational Structure and Quality Management System which is in accordance with the international organization standard ISO 9001:2008. Through its effective application BETAPLAN is able to maintain and guarantee the continuity of the high quality service, which the firm provides for the benefit of the clients and projects. In-house basic and follow-up training in technical issues and various software tools (BIM, CAD, Team work communication managers and others) are provided to the relevant company staff. In this way, we are able to maintain and guarantee the continuity of the high quality service, which our firm provides.

Over the years BETAPLAN has become familiar with domestic or international Green Building Certification Systems, such as LEED, MINERGIE, BREEAM, QSAS or KENAK. More specifically, the Stavros Niarchos Foundation Cultural Center, in which BETAPLAN is the executive architect, implements the LEED certification system and is the first project in Greece aiming for Platinum LEED certification rating.


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 currently the 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.
