Interior architect

This page was last modified on 21-06-2017

In order to operate as an interior architect, business executives must hold a business permit.

The business permit is granted to the business (either the business executive operating under his own name, or the company he runs) provided that:

  • the business executive 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').

Compliance with these provisions is verified by the General Directorate for SMEs and Entrepreneurship when the application for a business permit is submitted.

After the business permit has been obtained and depending on the legal business structure chosen, the company has to proceed with various registrations/affiliations before it can begin its activity.

Interior architects who are legally established abroad (in the Swiss Confederation or in a country of the European Economic Area) may provide temporary and occasional services in Luxembourg without business permit and without giving prior notification to the General Directorate for SMEs and Entrepreneurship.

They are nevertheless required to comply with all the rules of the profession, in particular ethical requirements, which are in force in Luxembourg.

Carry out your procedure:

Who is concerned

The activities of interior architects include:

  • creating and designing the interiors of buildings;
  • drawing up the building's interior plans;
  • summarising and analysing the different activities needed to implement the plans.

All professionals holding a business permit as architects can also work as landscape architects and interior architects.

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


To document that they have the necessary qualifications to work as an independent interior architect, the applicant must have a bachelor's degree in interior architecture or its equivalent (issued by an institution of higher education recognised by the country in which it is located ; the degree has to be filed with the register of certificates).

How to proceed

Business permit application in Luxembourg

Documentary proof of qualification

Applicants may work as interior architects in Luxembourg if the profession is regulated in their country of origin and if they are entitled to exercise it.

Applicants must provide the General Directorate for SMEs and Entrepreneurship of the Ministry of the Economy with a certificate from a competent authority in his country of origin that certifies their access to the profession.

The interior architect must be entitled to use the academic title of architect before a business permit can be issued. To this end architects must submit their professional qualifications to the register of certificates.

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

Specificities of BENELUX university diplomas

These diplomas are recognised automatically (in terms of their inscription into the register of certificates) in all 3 BENELUX countries, provided that they have been delivered by an institution that is recognised in the country in which the diploma has been delivered.

These diplomas therefore do not need to be inscribed in the register of certificates in Luxembourg.

However, automatic recognition is limited to the following degrees:

  • for the Flemish community of Belgium: the "graad van bachelor" and the "graad van master";
  • for the francophone community of Belgium: the "grade académique de bachelier" and the "grade académique de master";
  • for the germanophone community of Belgium: the "Diplom Master" and, if applicable, a masters' degree from the germanophone community of Belgium;
  • for the Netherlands: the "getuigschrift bachelor" and the "getuigschrift master".

Documents attesting to professional integrity

In order to provide proof of professional integrity, applicants must attach the following to their business permit application:

  • applicants residing in Luxembourg for more than 10 years:
  • applicants who do not reside in Luxembourg or have been residing in the country for less than 10 years:
    • an affidavit (sworn statement);
    • a notarised delaration providing information on possible bankrupcies in the past ("déclaration de non-faillite");
    • an extract from the police records or equivalent issued by the State in which the applicant has resided during the 10 years prior to the application.

Other documents to be submitted with the application

The following documents must also be attached to the business permit application:

  • for citizens of Luxembourg, the European Union, or the European Economic Area (Iceland, Liechtenstein, Norway, Switzerland):
    • a copy of the applicant's ID card or passport;
  • for citizens of other countries:
    • a written confirmation from the minister in charge of immigration that the applicant meets all requirements for obtaining the requested residence permit, with the exception of the recognition of professional qualifications necessary for the profession of interior architect;
  • proof of payment of stamp duty (droit de chancellerie), in the form of:
    • either a tax stamp, value EUR 24, purchased at the Indirect Tax Authority (AED);
    • or the proof of payment of EUR 24 into the IBAN account LU09 1111 7026 5281 0000, BIC code: CCPLLULL of the Diekirch Revenue Office, with the following communication: 'autorisation de commerce';
  • in the event of an application for a business (legal person), the company's articles of association which have been filed with the Trade and Companies Register.

In the event of an online application for a business permit via MyGuichet (with a Luxtrust card), the system will automatically generate the list of supporting documents to be attached to the application, which may vary depending on the data entered by the applicant.

Executives who run their business as a sole proprietorship can collect their business permit at the Joint Social Security Centre (CCSS).

Executives who run their business as a company (partnership / capital company) will receive their business permit by post.

Temporary service provision in Luxembourg

Interior architects established abroad (in the Swiss confederation or in a country of the European Economic Area) may freely offer services in Luxembourg. There is no need for a business authorisation or a specific notification to the Ministry of the Economy.

However, when coming to Luxembourg, service providers are subject to rules of professional, regulatory or administrative conduct directly related to the professional qualifications that are in force in Luxembourg, along with the related disciplinary provisions applicable for professionals in Luxembourg.

Interior architects can contact the Order of Architects and Consulting Engineers (OAI) for further information.

They also need to check if their insurance in their country of origin covers all legal and contractual liabilities incurred in Luxembourg and, if necessary, adapt their insurance coverage or contract specific liability insurance covering their activities as well as those of their employees.
