Last update

In order to be able to practise as an independent architect in Luxembourg, applicants must hold a business permit.

The business permit is granted to the business (either the business manager operating under their own name, or the company they run) provided that:

  • the business manager meets the legal requirements in terms of qualification and professional integrity;
  • the business has a fixed physical establishment in Luxembourg (no so-called 'letterbox companies').

The fulfillment of the conditions for access to the profession is checked by the General Directorate for Small and Medium-Sized Enterprises at the time the business permit application is submitted.

Depending on the legal form chosen, the applicant must proceed with different registrations/affiliations before starting their activity.

Architects established abroad (in the Swiss confederation or a country of the European Economic Area) may provide occasional and/or temporary services in Luxembourg.

In the context of public procurement contracts, there are specific hourly reference rates (French, Pdf, 96 Kb) for architectural and engineering work for the public sector.

Who is concerned?

The activities of architects include:

  • creating and designing works of construction, urban planning or land use planning;
  • drawing up plans for these works;
  • summarising and analysing the different activities needed to implement the plans; and
  • consulting and expertise services, in particular:
    • research of basic data for the project;
    • preliminary design, design and outlines;
    • project plans, design development, cost assessment;
    • building permit applications;
    • detailed assessments and plans of construction elements;
    • drawing up specifications in accordance with trade association regulations;
    • calls for and assessment of tenders;
    • overseeing the execution of works;
    • assisting with the acceptance of completed works.

Moreover, only an architect may sign the plans necessary for obtaining a building permit.

All professionals holding a business permit for architects can also perform the activities of landscape architect and interior architect.

Salaried workers or civil servants do not need a business permit in order to work as architects for their employer or administration.


The applicant must have a diploma or degree in architecture (or equivalent). This diploma must be:

  • issued by a higher education institution recognised by the State in which the institution's head office is registered;
  • possibly, entered in the register of certificates after:
    • a minimum of 5 years of full-time education; or
    • a minimum of 4 years of full-time education plus 2 years of certified professional training.

Preliminary steps

Automatic recognition of professional qualifications

The rules for the recognition of the professional qualifications for the profession of architect are the same in all countries of the European Union.

Thus, recognition is automatic if the applicant can present the documents listed in Annex V point 5.7.1. of Directive 2005/36/EC of the European Parliament and of the Council of 7 September 2005 on the recognition of professional qualifications. Normally, these are the following 2 documents:

  • the diploma listed in the Annex mentioned above;
  • a certificate confirming that the applicant has access to the profession of architect in the country where the diploma was awarded.

Caution: be sure to always check the latest consolidated version of the Directive. Annex V is updated regularly.

Graduates are therefore requested to check with the competent authorities in the country in which they received their academic title if there are any additional conditions that may apply to accessing the profession.

Application for recognition of other qualifications or professional experience

The applicant can submit an application for recognition of their professional qualification if:

  • their diploma is not recognised by the country where they studied; or
  • they do not have a certificate confirming access to the profession in the country where the diploma was awarded.

Applications for recognition must be submitted to the Ministry for Research and Higher Education (Ministère de l'Enseignement Supérieur et de la Recherche). Applicants must demonstrate that they have received training that meets at least the following criteria:

  • duration of the training course:
    • a total of at least 5 years of full-time study at a university or comparable educational institution, culminating in successful completion of a university-level examination; or
    • at least 4 years of full-time study at a university or comparable educational institution, culminating in:
      • successful completion of a university level exam;
      • a certificate attesting the completion of at least 2 years of professional training.
        The professional training takes place only after the completion of the first 3 years of study. At least one year of the professional training contributes to the development of the knowledge, skills and competences acquired during the curriculum. To this end, the traineeship is carried out under the supervision of a person or entity that has been approved by the competent authority in the home Member State. This supervised traineeship can take place in any country. The professional traineeship is evaluated by the competent authority of the home Member State;
  • the content of the training: architecture is the main element of the course. This course must maintain a balance between the theoretical and practical aspects of architectural education and ensure the acquisition of at least the following knowledge, skills and competences:
    • the ability to design architectural projects that meet both aesthetic and technical requirements;
    • an adequate knowledge of the history and theories of architecture and related arts, technologies and humanities subjects;
    • a knowledge of fine arts as factors that may influence the quality of architectural design;
    • an adequate knowledge of urban planning, planning and the techniques used in the planning process;
    • comprehension:
      • the relationship between people and architectural creations on the one hand, and architectural creations and their environment on the other; and
      • the need to harmonise architectural designs and spaces in accordance with human needs and scale;
    • an understanding of the architectural profession and its role in society, in particular by developing projects taking into account social factors;
    • a knowledge of the research and preparation methods of construction projects;
    • a knowledge of structural design, construction and civil engineering issues related to the design of buildings;
    • an appropriate knowledge of the physical problems, the technologies as well as the function of buildings, in order to design them with all the elements of indoor comfort and climate protection in the context of sustainable development;
    • the technical skills enabling the architect to design buildings that meet user requirements while respecting the limits imposed by budget requirements and building regulations;
    • an appropriate knowledge of the industries, organisations, regulations and procedures involved in the implementation of building projects and the integration of plans into planning.

Establishment of the level of the diploma: entry in the register of certificates

If the applicant's diploma is not included in Annex V of the Directive, the Minister of the Economy may require the applicant to have their diplomas entered in the register of certificates. The purpose of this procedure is to establish whether the diploma presented corresponds to a Master's degree.

Official diplomas from Belgium or the Netherlands do not have to be registered. Their level is automatically accepted.

Caution: registration is different from recognition for access to the profession. Registration only allows to establish the official level of the diploma presented by the applicant.


The stamp duty for the issue of a business permit amounts to EUR 50.

If the establishment is moving to another address, the applicant must notify this, free of charge, to the General Directorate for Small and Medium-Sized Enterprises. In this case, the applicant will receive a new business permit free of charge.

It should be noted that for applications submitted in the context of a business set up in the form of an SARL-S, the applicant must forward the draft constitutional documents of the SARL-S to the Ministry of the Economy.

Application processing time

Temporary provision of services in Luxembourg

The service provider is also subject to the disciplinary provisions applicable to Luxembourg professionals.
