Plan B: Hybrid City Competition

Registration date:


Submission date:




In an urbanizing world, we face the ever-growing need for housing. We need to build millions of new buildings while simultaneously taking care of the environment. Wood is the only major construction material that stores carbon. This is why we need to use more of it. However, this cannot sacrifice efficiency. We need to support construction companies to use more wood by creating elements, modules and concepts that fit the way they construct today – and to make wood, steel and concrete work as one.This is why we created the Hybrid City Challenge.
Open Source Wood calls for building engineers, construction companies and architects to join in the initiative in finding the world’s best solutions towards more efficient, sustainable, modular and industry compatible ways to build.

The brief
Design an element, module or concept.
Select an existing multi-story building made of non-wooden materials.
Choose an element used in the building and redesign it using Kerto LVL (laminated veneer lumber) as the main material.

Criteria:The design should be sustainable (uses Kerto LVL as main material), efficient (modular and fits the current way of building) and include adequate amount of information and design materials for actual construction projects.

Hybrid City skylineAwards
The winners will be chosen by a group of experts within the Open Source Wood Community. Evaluation is done based on the designs efficiency, sustainability, practicality and the level of provided information and design materials.
