3 Solid wood house construction systems – differences and advantages

CLT, MHM, or Holz100—which system is right for you?

Solid wood construction systems are becoming increasingly popular in Mallorca, as the island's charm is combined with modern architecture: stable structures, a healthy indoor climate, and sustainable construction methods. Three outstanding systems are in the spotlight: cross-laminated timber, also known as CLT, the MHM solid wood wall system, and Holz100 from Thoma. Each of these systems has its own strengths—depending on the project goal and climate in Mallorca—and TreesM Baleares accompanies architects, planners, and builders as a competent specialist through all phases from planning to implementation.

Cross-laminated timber, or CLT, impresses with its exceptional load-bearing capacity and dimensional stability. By gluing several layers of wood crosswise to each other, a building material is created that allows for large spans and reduces support loads. This makes it possible to create open floor plans without compromising on stability. For Mediterranean Mallorca, this means that Architects can create spacious, airy rooms that blend seamlessly with the bright island light. CLT also offers good sound insulation and can be efficiently implemented thanks to its easily planable prefabrication. In Mallorca, this most robust form of solid wood construction harmonizes with the natural breathability of wood, provided that a well-maintained, air-permeable design is used.

Another highlight is the MHM solid wood wall system. It uses a completely glue-free construction method that mechanically connects untreated wood panels using aluminum pins. The result is a breathable wall construction that allows moisture to escape while maintaining a healthy indoor climate. This solution scores points for its fast construction thanks to prefabricated panels and reliable stability without adhesives. The MHM system is particularly useful for the climate in Mallorca, which can bring increased moisture loads due to its proximity to the sea: the open wall structure, which promotes air circulation, helps to regulate moisture efficiently and thus prevent mold growth. The builder benefits from a durable, sustainable construction that is a useful addition to both new buildings and renovations.

Holz100 by Thoma complements this trio with a construction method that is consistently free of glue and metal. Here, layers of wood are joined together using expanding beech dowels to form a stable, natural material structure. The result is outstanding insulation and a natural indoor climate, which is supported by the open cell structure of the wood. Holz100 thus sets new standards for healthy living in Mallorca: low emissions, the highest ecological quality, and an awareness of a pleasant indoor climate—particularly important in hot summers and mild winters. The absence of glue and metal also ensures that pollutants are virtually eliminated and that air quality is permanently improved.

TreesM Baleares sees itself as your reliable partner when it comes to solid wood systems in Mallorca. From the initial consultation and planning to turnkey implementation, we provide comprehensive expertise and tailor-made solutions. Our aim is to give builders, architects, and planners clear guidance: Which system solution best suits the specific requirements of a project, the island's climate, and the desired health and environmental goals? You benefit from our in-depth expertise in all three construction methods—CLT, MHM, and Holz100—as well as our proximity to the local building culture, our references in Mallorca, and our close cooperation with local trades and suppliers.

Choosing the right solid wood system is closely linked to the climate in Mallorca. For spacious living concepts with open areas and high architectural standards, CLT offers excellent possibilities in combination with breathable, air-permeable details. The MHM system is ideal when fast construction times, glue-free construction, and natural air circulation are required—perfect for a healthy indoor climate and robust exterior wall construction in a marine environment. Holz100 is particularly suitable when the highest demands are placed on a healthy, low-emission indoor climate, excellent insulation, and ecological construction.

With TreesM Baleares, you not only receive a technical solution, but also partnership-based support throughout the entire process. We work with you to analyze your requirements, check load-bearing capacity, thermal insulation, moisture behavior, and construction time, and find the optimal system solution—tailored to your budget and schedule. Our expertise as a timber construction specialist inspires confidence: we explain in clear terms what lies behind each system, what the advantages and disadvantages are, and how long-term costs, maintenance, and energy efficiency can be positively influenced.

When you choose sustainable timber construction in Mallorca, you benefit from three strong options that differ in terms of load-bearing capacity, breathability, and indoor climate. CLT offers maximum spans and dimensionally stable structures, MHM provides glue-free, breathable walls with fast construction times, and Holz100 sets new standards for healthy, low-emission living. TreesM Baleares is always at your side as a competent partner—for planning that convinces, implementation that lasts, and results that will give you pleasure for a long time to come.
