ebniecolo.tn offers a « tectonic » (technical and architectural) expertise of vaulted works, in their different forms and structures, thanks to the technical knowledge as well as the varied experiences of the projects carried out within the framework of the professional activity of qartbunDESIGN sarl.
Design
Our mission is to turn NBS materials and green building design into an everyday pleasure
Every project we share here is a testament to our commitment to sustainable innovation and traditional craftsmanship. These achievements represent our technical foundation and our passion for earth-based architecture, but they are merely the first steps of a much larger vision. We are constantly evolving, and this is only the beginning of our journey toward a greener future.

Expertise
Green Building & Bio-Climatic
ebniecolo.tn regularly provides expertise to private individuals and institutions wishing to take the step of « ecological transition ». This expertise and consulting mission concerns the housing, retail and industrial sectors.
Natural Based Sourcing Materials
Raoued
The owner asked us for an expertise on the implementation of the natural lime plaster (NHL3,5 from INTERCHAUX). His mason was neither experienced nor trained in certain skills. The plaster was applied inside directly on the the CEB from SOIB.
Khezama
The owner asked us for an expertise on the implementation of the natural lime plaster (NHL3,5 from INTERCHAUX).His mason had an approximate knowledge of lime coatings, but not enough. His first tests were not conclusive. We identified the quality of sand and the appropriate mix-design. The rendering was applied on the outside directly on 12-hole pre-coated brick with cement.
Vaulting
Heritage Approach
ebniecolo.tn proposes an expertise of the architectural and urban heritage, in Tunisia, according to three entries: the technical value (the know-how: to renovate and restore according to the authentic constructive techniques), the value of knowledge (the knowledge: the historical stratification) and the socio-economic added value (the knowledge to be: the heritage is not an object in time, but it is anchored in its social, economic and spatial temporality).
Entrepreneurship
In order to strengthen the industrial fabric of alternative materials and construction systems, it is important to encourage and frame innovative projects in terms of ecological, natural, low carbon and energy impact materials.
ebniecolo.tn offers training, coaching and specific support in this sense.
