Membership in Architecture Sans Frontières International can be granted to local, national and international organisations which approve the Charter of Hasselt.
When an organisation wished to become a member it must submit:
1. A signed copy of the Charter;
2. Its deed of incorporation (registration document);
4. Any other document required by the Board. There is only one category of members, namely the effective membership (with the right to vote at ASF-Int meetings).
The documents must show that the organisation has been constituted as an independent and autonomous entity, and that it represents architects and/or persons having a specific interest in the field of architecture, town planning or construction.
