French craftsmanship and expertise
A bespoke Kostum
Kostum is a French brand based in Brittany, right by the coast. Every day, 700 passionate employees and carpenters come together to design your gates, fences, s and pergolas by hand. Kostum products are 100% repairable and designed to last and accompany you for as long as possible. Our use of aluminium — a robust, rust-proof material - combined with our expertise across the entire production chain and our high-quality standards enables us to offer a 30-year guarantee on the manufacture and finish of our products. Because every garden is unique, Kostum creates bespoke designs and incorporates exclusive decorative features into its joinery in collaboration with artists and designers.

Produit de très bonne qualité, très bien fini et parfaitement pensé. Très bien emballé à la livraison. Aucune mauvaise surprise car les mesures prises ont bien été respectées. La pose s'est déroulée sans problème, effectuée par un professionnel compétent ayant fourni un travail soigné et méticuleux. La motorisation du portail à pu être réalisée sereinement du fait d'une zone renforcée prévue pour accueillir la fixation des bras des moteurs en respectant l'esthétique sans négliger la solidité. Le résultat final est très satisfaisant, très esthétique et inspire confiance. Félicitations au concepteurs et au fabriquant.
