a revolutionary technology
There is a huge unmet demand for housing, which increases every year. In the Global South, more than one billion people lack appropriate housing. Urbanization, migration, and population growth increase the backlog every year. But even in first world countries like the United States, more than 60% of people living in urban centers struggle with housing affordability.
It is clear that there is no single cause for this global issue, and that there is no single, easy solution. But at Citra, we strongly believe that innovation is the best way to bring sustainable, affordable, and beautiful homes to as many people as possible. Unfortunately, in the past 70 years, the construction industry has not been able to innovate at the same pace as most other industries.
In the past 10 years several breakthrough technologies such as mobile internet, Computerized Numerical Control (CNC) cutting machines, robots, and parametric design have enabled us to come up with new ways of designing and building homes. We believe that our technology is a leap forward for the construction industry and that it will assist the current and coming generations in solving the global housing and climate challenges.
Citra building technology
The Citra system is incredibly strong and of high quality while eliminating steel and reducing the external building shell to the absolute minimum: A 140 mm thick Citra wall has a five times better thermal insulation value than a 280 mm thick cavity wall. And Citra walls can easily withstand a harsh North American or European winter.
The main materials used for the Citra building technology are plaster (98% of the weight), Magnesium Oxide (1%), and Expanded Polystyrene (1%).
Citra walls are exceptionally strong when compared to conventional walls. Citra can build roofs with the same building technology. A Citra building shell is about 50% lighter than a cavity brick wall house and has a greenhouse gas footprint that is about 50% less.
The Citra plaster is a specially designed mix with a compressive strength of up to 25MPa. Both on the inside and outside, there is a 30 mm plaster layer that gives the home strength and durability.

Our Design Philosophy
Our design philosophy is informed by four key principles:
Our Design Tools
Citra uses a design-for-production design technique where the production and construction constraints are part of the planning from the beginning. In order to achieve great results, we use a high-end design and planning software along every step of the way:
Our predesigned houses are built in a simple four-step process:
