My name is Oliver von Malm. I am and architect and founder of a social business called Start Somewhere. We have created a low cost, easy to use, construction method for affordable housing. The core of our technology is a new construction block called TwistBlock that is fast and easy to handle, reusable, can build any shape. It is being produced in local factories in low income areas. With this approach we aim to change worldwide living conditions of vulnerable communities in the Global South.
