Building with Kerto LVL elements
Flexible, sustainable and beautiful buildings besides revaluating the existing building stock. We should listen to the end-users for whom we build and offer flexibility for the wishes of the next generation. This means buildings should be built differently.
Maskerade® offers a wooden frame from Kerto LVL beams and studs with a long-term vision on flexibility, where people can create their own environment.
The Maskerade® building method
The Maskerade® building method is industrially produced by assembling [large] prefabricated elements for floors, walls and facades. This results in a short building process and a highly-controlled quality. The frame supplies the aesthetic, constructive and technical base. The various finishing options (such as: arrangement, installations and finishing) makes the frame complete. The separation of frame and finishing increases a building’s viability and guarantees you a long term of exploitation [ >100 Years…...…...].
The exterior of a Maskerade building should always fit within its surroundings and should have a high feel-good content.
Freedom of design and use are at the core of this method. The system gives architects and builders facilities by using the Maskerade® library of details in their own practice.
Maskerade is a modular system tuned on [standard] structural possibilities of KERTO LVL.The system is based on a vertical way of building and enables you to build up to 5 stories within a day….both wind and waterproof!
A signature characteristic of the Maskerade building construction is that the floors are imposed in a slot in the wall and façade. In this way, the walls and facades can be stacked so the shrinking in the construction is avoided and the stability improved. *]
The key element in the construction is the Flexvloer ®. This floor element has a standard span of 7,5m and a width of 2,5m. The controlled production allows a very rigid floor with excellent comfort for the user. The wall and façade elements have a standard height of 3,5 m. The floor, wall and façade elements are all prefabricated including insulation, glazed windows and installations.
Maskerade is a modular system tuned on the [standard] constructive KERTO LVL offers.
*] In case of earthquakes or a heavy storm, Maskerade cab guarantees the necessary strength by stabilizing the nodes and other connections.
To guarantee a continuous quality, the system MASKERADE offers a library and 3D-BIM models. The developed design aspects and details have proved themselves in practise during the last decade and are now usable for all kinds of circular buildings.
Maskerade is a vapour permeable and air-tight building system. To improve the comfort in winter and summer a cellulose isolation is injected in the walls, façade, roof and ground floor. Because of this, the building temperature and humidity is constant and gives a comfortable, healthy indoor environment.
The glued insulation and acoustics are secured in the finish of the Flexvloer® and the slot in the walls and facades.
ARRANGE is a quick and easy solution for developers to build a terraced housing complex, all the while saving their valuable time, energy and nerves. To succeed in doing that, we are using the Pattern Building system and the Creatomus platform for visualising the desired complex.
We are providing the developer with different flexible house plans for them to explore for their potential clients. Our goal is to make building terraced housing easy, fast and most importantly flexible.
Following the Hackathon Open Source Wood x FCBA challenge 2020 on reusability, Team 7 presents its building concept for a modular post and beam system. The main innovation is its connector system for non-load-bearing exterior walls. It aims to facilitate building for deconstruction by addressing a current knowledge gap in panelized, removable exterior walls.
The suggested system uses prefabricated, closed exterior wall panels of standardized dimensions. This means the panels can be transported compactly, along with the other standardized construction elements (posts, beams, etc.) which facilitates offsite construction. The exterior walls' load is taken by the post and beam system through the connector and steel leg angle, and bolted aib the connector at the top.
Combined with a post and beam system using few standardized connectors, this concept could help build highly evolutive, deconstructable buildings where components can easily be replaced, and building extensions are more easily planned. Looking forward, the concept could be pushed further through parametrization and mass customization, which would allow applying it to a wider variety of building archetypes.
In response to Open Source Wood Initiative EASA 2020 Challenge, we present T-LAB: Timber Laboratory for Co-operative Living.
The T-Lab project proposes a modular multi-story housing concept using the elements and modules available at opensourcewood.com. The project responds to the challenges of urbanization and increasing the densification of city structures through an architectural, social, and environmental lens. The main material of the building is wood, specifically Metsä Wood's Kerto LVL. The proposal is comprised of a system of modules and building components that are ideal for offsite construction and are easily transferable to the construction site.
The project is a viable alternative to traditional housing, proposing a cooperative building model whereby benefits of practicality and efficiency are carried through to the end-user.

Combining prefabricated elements and modules with steel brace straps and steel consoles, placed on a concrete base.
This is an unreal scenario in New York, in 1955, imaging that the designers of the famous 39-story Seagram Building, Mies Van Der Rohe and Phillip Johson, knew the technical advance of mixing steel, concrete and wood in structures (Hybrid structures tech) and could get a low impact on environment, based on CO2 fingerprint materials and passive solar building design knowledge.
The Alexandra Road Estate an iconic example of mid-twentieth century brutalist architecture. The form and composition of the scheme make it a vital and appropriate example of mass housing, that could be reimagined as a low carbon building for the 21st century.
In this proposal, we have explored the use of Kerto LVL in mass housing as an alternative to concrete. The structural performance of Kerto LVL allows us to be ambitious with the design of mass housing. The embodied carbon for the proposed structure is approximately 50% of the existing building, without taking in to account the carbon sequestered in the timber. By proposing pre-fabrication and the ability to disassemble joints between walls and slabs we can support reuse and the circular economy. Exposed timber promotes wellness and encourages the use of timber in buildings.
Porous high-rise as combination of vernacular structures with green terraces in urban environment
Nowadays importance of every plot of land due to high-speed urbanization prompts the popularity of the construction of high-rise buildings. Progress in timber construction allows to build with massive wood columns up to 12 storeys and more.
Combination of 2 modules allows to create porous structure of high-rise buildings with 'holes' - terraces for greenery.
The purpose of my proposed structure was chosen to become a fast, easy-build, light construction method for this student accommodation, especially suited for off-site construction – to meet the demands of the crisis. This prototype, or perhaps typology does not necessarily have to be catered to the given site as it can be copied and inserted into any gap of the city fabric – multiplied and easily injected into any small areas like an acupunctured eco-friendly housing typology.
An understanding trying to create an infrastructure for the dense cities which is adjustable in means of hight and width with using wooden elements that are also easy to produce, apply and cheap.

'Kokoon' is a design and construction project built to address the current housing situation in Europe where a shortage of short-term housing affects many residents from asylum seekers to students and families whose apartments undergo renovation.
The project is a pre-fabricated and transportable module for living that can be stacked or spread into a larger configurations for a period of a few weeks or months, The units can then be moved to another location when necessary.
The scale and flexibility of the project allows for a large range of configurations to fit various urban and sub-urban contexts. In each case, the units are finished inside with integrated lighting
and furniture with only stacking and connection work done on site.
To test and demonstrate the possibilities of this modular system, three prototype modules were built at full scale and stacked together to be put on public display.
Based in the material features as flexibility and stability, we started a research about wood joints, which in turn generated a construct system. Thus the whole is generated from the unfolding or replication of its minimum modulus (detail), respecting the properties of the material and optimizing its use.
Besides being a renewable and recyclable material, wood panels are easily find all over the world, which allows manufacturing the parts near the construction area, reducing the cost of transportation and developing the local market.
The combination of the clip that facilitates the connections with its layer-by-layer building system ensures that the construction is always stable throughout the entire process. This condition allows non-specialized people using only a rubber hammer be part to the assembly process and it makes the system ideal in an accelerated and organic urban development society.
