The foundations of demountable and reusable buildings

The imperative of longevity in building design 

Constructing buildings with an emphasis on long-term use is essential for two key reasons. First, long-lasting structures promote resource efficiency by reducing the frequency of new constructions. This approach conserves raw materials and decreases the environmental impact associated with manufacturing and transportation. Second, these buildings enhance economic viability by offering better returns on investment. They can be adapted to serve multiple purposes over time, allowing owners and developers to modify spaces to meet evolving needs without incurring the substantial costs of new constructions. 

A prime example is the transformation of the Östermalmshallen market hall in Stockholm, Sweden. Originally a temporary structure, it was disassembled, transported 500 kilometers, and reassembled in Mölnlycke as a padel hall. This project underscores the value of constructing with durable wooden materials like Kerto® LVL( laminated veneer lumber), which facilitate demounting and reuse. Such adaptability not only extends a building's functional life but also enhances its market appeal, providing investors with sustainable and profitable opportunities. 

Designing for modularity and reusability 

To achieve longevity and adaptability, buildings must incorporate specific design principles. Modular construction plays a crucial role by utilizing prefabricated modules that allow components to be assembled, disassembled, and reassembled with ease. This modularity facilitates modifications and expansions without requiring significant structural overhauls. Standardized connections are another essential aspect, as employing uniform systems like bolts and screws ensures that parts can be easily detached and replaced. This approach simplifies both maintenance and adaptation processes. Additionally, the selection of durable and recyclable materials enhances a building's lifespan while ensuring that its components can be reused or repurposed in the future.  

Case Study: Building D(emountable) – Steel frame with wooden elements 

A good example of demountable and reusable building is Building D(emountable) in the Netherlands, which employs a hybrid construction of steel frames and wooden elements. This combination provides structural integrity and allows for flexibility in design and function. A key material in this structure is Kerto® LVL, a product known for its strength, light weight, and versatility. 

Kerto LVL is manufactured from Nordic spruce, sourced from responsibly managed forests. The material’s exceptional strength-to-weight ratio makes it an ideal choice for construction elements that require precision and durability. In Building D(emountable), Kerto LVL elements are seamlessly integrated with the steel frame to create a strong and carbon storing structure. 

The use of Kerto LVL elements also facilitates the building’s demountable nature. Its lightweight properties simplify transportation and assembly, while its consistent quality ensures easy handling during disassembly and reconfiguration. Furthermore, Kerto LVL's sustainability credentials align with the broader goals of minimizing environmental impact, as the material is renewable and reusable. 

The design of Building D(emountable) emphasizes adaptability and longevity. The combination of steel and Kerto LVL elements ensures that the building can be easily disassembled and reassembled, allowing it to be relocated or modified for different purposes. This approach highlights the possibilities of hybrid construction in creating resilient, reusable, and more sustainable buildings. 

Material data banks support circular economy 

Material data banks, like Madaster, are digital platforms that track and document materials used in buildings and infrastructure. Their core principle is to create material passports, which store detailed information about the composition, origin, and potential reuse of materials. 

The goal of these platforms is to promote a circular economy by making materials more transparent and accessible for reuse, reducing waste, and minimizing environmental impact. By providing insights into the value and recyclability of building components, material data banks help architects, builders, and investors design for sustainability and extend the lifecycle of materials.

Benefits of demountable and reusable buildings 

The adoption of demountable and reusable buildings offers several advantages: 

• Cost savings: The ability to modify existing structures reduces costs associated with demolition and new builds, offering economic benefits to owners and developers. 

• Adaptability: Buildings can be reconfigured to serve various functions, accommodating changing needs without the necessity for new constructions. 

• Reduced disruption: Modifying existing structures causes less disruption to the surrounding environment and communities compared to new construction projects. 

• Sustainability: Reducing the need for new materials and minimizing construction waste significantly lower the environmental footprint of buildings.
