We provide integrated services in building permits, technical studies, and design, covering the entire lifecycle of a project — from the initial concept to its final maturation.
By combining technical expertise with extensive experience in licensing and regulatory processes, techne. delivers solutions that support the safe, functional, and efficient development of every project.
Building
Permit
A Building Permit is an official administrative authorization issued by the Urban Planning Authority allowing the legal execution of construction or technical works on a property. Its purpose is to ensure that every project complies with urban planning regulations, enviromental standards and building codes, maintainining order and safety in the built environment.
Legal Framework
The issuance of building permits in Greece is primarily governed by:
- Law 4495/2017 (“Control and protection of the built environment”)
- New Building Code (Law 4067/2012)
- Ministerial Decision for the electronic permitting system e-Adeies
- Special decrees and urban planning regulations applicable to each area (e.g., General Urban Plans, Zoning Plans, etc.)
Τypes of Building Permits
Building permits may be issued for:
- New constructions or extensions (vertical or horizontal)
- New Building Code (Law 4067/2012)
- Change of use of an existing building or space
- Restoration, reinforcement, or reconstruction of a structure
- Demolition of existing buildings
- Installation of prefabricated or temporary structures
Issuance Procedure
The process is carried out electronically through the e-Adeies online platform and consists of two main stages:
A. Building Approval
Verification of planning and ownership data
(zoning, plot suitability, permitted use, etc.).
Submission of:
- Topographic diagram
- Site coverage plan
- Property titles
Certificates and approvals from relevant authorities
(Archaeological Service, Forestry, Ministry of Culture, etc.).
B. Building Permit - Final Approval
Submission of detailed design studies, including:
- Architectural drawings
- Structural design
- Electromechanical studies
- Energy performance study
- Fire safety study, etc.
Upon approval, the permit is issued electronically, assigned a
unique permit number, and remains valid for 4 years.
Building permits remain valid for four (4) years from their issuance date for the erection of new buildings, and for one (1) year in cases of demolition or excavation works.
Renewal is possible provided that construction has commenced or upon a duly justified request by the owner prior to the permit’s expiration.
Architectural
Preliminary
Design
Our architectural design process begins with the Preliminary Design, where we develop conceptual proposals that define the project’s spatial organization, form, materials, and aesthetics in alignment with the client’s needs and the site’s characteristics. This stage focuses on translating ideas into coherent architectural concepts through plans, 3D models, and visual presentations.
Following this, the General Final Design phase refines the selected concept into a complete architectural solution. It includes the development of drawings for the building permit, coordination with structural and electromechanical designs, and compliance with all relevant regulations and building codes. This comprehensive stage ensures that the project is ready for implementation, combining design excellence with technical precision.
Structural
Design
E&M
Designs
Our Electromechanical Design services ensure that every project is equipped with efficient, safe, and sustainable building systems. We provide integrated Electrical and Mechanical design solutions tailored to each project’s architectural and operational requirements.
Our expertise covers all building types — from residential and commercial developments to hospitality and industrial facilities — delivering reliable systems that enhance comfort, performance, and energy efficiency.
Services include:
- Electrical power and lighting design
- Low voltage and data systems
- HVAC (Heating, Ventilation & Air Conditioning) systems
- Water supply, drainage, and fire protection design
- Energy efficiency optimization and sustainability integration
Through precise planning, advanced modeling, and compliance with international standards, our E&M designs contribute to the long-term value and functionality of every building.
Topographic
Surveys
Our Topographic Survey services provide precise, detailed mapping of land features to support construction, planning, and design projects. Utilizing advanced surveying equipment and techniques, we accurately capture elevations, contours, boundaries, and existing structures. Our surveys serve as a critical foundation for architectural designs, engineering plans, and land development projects, ensuring compliance with local regulations and maximizing project efficiency.
Whether you require surveys for urban development, infrastructure projects, or private land planning, our team delivers reliable and accurate data to guide your decision-making process.
