We developed two modules in the 369 pattern building system that have an angled edge that is not at 90 degrees. What's the angle?... Firstly the angle comes from the mathematical relations of 369 modules. We split the existing module six (6m by 3m module) into a smaller and a larger module. The smaller modules orthogonal edges are 3 m, 3 m, 1,5 m long + "diagonal" edge. The bigger module edges are 3m, 3, m, 4,5 m + "diagonal" edge. So we get an angle for the "diagonal" edge that is modular in every direction. The concept for designing the new modules was that the change of the existing modularity should be as small as possible, but at the same time the outcome should give us as many options as possible. It is important to respect the work that is already done and functioning well. Adding new diagonal axises into an orthogonal 369 modularity we get new aesthetics and architectural qualities and options to arrange the space more freely. Why is it good?.. Building lots often have random shapes and our new options help us to use the land more sensibly for example following the building lot boarders. The more options we have in shaping buildings, the easier it makes it follow the landscape and other elements around us. The new modules help us to design the built environment according to its surroundings and landscape. We also solved the diagonal interface and modular connectivity. We angeled two parallel kerto frame according to our new interface. Now we also had to solve the corner insulation situation, cause our new module combinations created 6 new joint situations. So we invented one corner insulation element that is also modular and this one product solves all the new corner situations. In every corner you use two of those new elements.

Key benefit

It makes it possible to arrange modules in 369 pattern building system in nonorthogonal ways. We offer more options and a sensitive relation between the building and the surrounding landscapes.

Ecological values

Building lots often have random shapes. More options to shape the building to the boarders of the plot help us use the land more efficiently and sensibly. The flexibility to design various building shapes helps us design our built environment, existing landscapes, and surroundings. We will have a less hard impact on landscapes and use our land more responsibly. More options in the modular system helps us create better architecture and improve the space around us. Developing modularity in general reduces ecological impact. Modular building elements are more precise because they are prefabricated, use material more efficiently and are much quicker and more efficient to build. This means that less labor hours, and an overall more economical construction. A modular building is not a finished product, it’s a process. Modules can be assembled and reassembled, this means, that we reuse already built objects and don’t produce waste. One of our objectives was that there should be an aftermarket community or marketplace where you can purchase and resell your room modules. We designed the corner joint insulation panel. The panel is also modular, so using just one product solves all the corner joints. You just combine 2 of these elements in every corner. We also modeled the corner joint so that it would be energy saving, without „cold bridges“ and the thermal situation fits within regulations. For that we used the program „Therm“ and the outcome was satisfactory.
