The Birth of CLT Greece

Coming from families with nearly a century of presence in the timber industry and sharing a common commitment to the numerous natural benefits of wood, the founders of CLT Greece envisioned introducing an innovative construction technology to the Greek market.

CLT Greece was established to bring Cross-Laminated Timber (CLT) to the forefront in Greece—a material that has already gained international dominance. In countries where wooden construction is a cornerstone of the building industry, CLT has been recognized as a pioneering, sustainable, and highly durable solution. However, in Greece, it remained largely unknown or misunderstood.

With profound knowledge of timber, the founders of CLT Greece recognized that the absence of this technology in Greece was not just a business gap but an untapped opportunity. It was a solution that needed to be introduced to the construction sector, offering new and reliable alternatives beyond conventional materials.

Twenty years ago, through collaborations with suppliers in Northern and Central Europe, they discovered CLT before it became a globally established material. They didn’t just observe—they experienced it firsthand. They worked with pioneering companies, studied production processes, witnessed projects come to life, and lived in CLT buildings, understanding its real value: rapid construction, fewer labor requirements, natural feel, thermal comfort, durability, and sustainability.

The conclusion was clear: who better to introduce and establish CLT in Greece than individuals who know, believe in, and continuously develop it? Thus, CLT Greece was born—not just as a company but as a mission. Its goal is to make CLT known, accessible, and dominant in the Greek market, bringing this transformative construction material of the future into Greece’s present.

The smell and sound, the feeling of the wood stay in our worlds since we are born

CLT Greece was launched as a separate entity with the mission to advance the adoption of mass timber constructions along with respect to our environment.
