After thorough research, I opted for a Kostum bioclimatic pergola. The installation was carried out perfectly by an approved partner. The pergola perfectly withstands the weather conditions of our Breton region and allows us to enjoy our terrace all year round. The after-sales service is also very responsive.

Very satisfied with our aluminum railing. The refined design integrates perfectly with our contemporary house. The color matches the sample and holds up well over time. Only small downside, the delivery time which was a bit longer than expected, but the quality is worth the wait.

We installed a Kostum gate and fence from the Céklo range. The quality is exceptional and the design very contemporary. The lacquering is perfect and the finishes are well-crafted. Our neighbors even asked us where we bought it!
