Architects Jean-François and Guy meet during their studies at the Saint-Luc Liège School of Architecture, where they quickly develop a friendship that proves to be unbreakable over the years. After graduating, their internships and a collaboration of over 2 years, they take an important step in their respective careers and together found the architectural office crahayjamaigne in 2000.

After more than 20 years in the field of architecture, they were eager to develop a new project idea complementary to their initial area of expertise. The publishing house was born in 2021 following an obvious reflection on the desire to enrich architecture through custom design for an even more intimate and personalized service. A designer then joins the team to assist them.

In 2023, the logo and name “ADDENDDA” take shape, bringing Jean-François and Guy closer to their dream of taking on a new challenge.

An “addendum” is a set of additional notes complementing a work. This image naturally seemed to correspond to the intention of creating custom objects to accompany architecture. The 4th “D” symbolizes Design, the additional element, the little extra that will enhance your living spaces.

In 2024, it is the year of the realization of their project through the first steps of the implementation of Joseph and Izi.
