The digital planned housing development in Borna combines proximity to nature with the metropolitan region of Central Germany. The cities of Leipzig, Gera, Chemnitz, Halle and Dresden are in the immediate vicinity. A 78,000 m² construction project is being built in Borna, pursuing a concept that is unique in Germany: The single-family home development is being realized entirely with the help of a multi-stage digital construction process.

Digitization enables transparency and individuality

Even in the sales phase, it becomes clear what the digital concept has to offer:  With the help of an online configurator, anyone interested can plan and design their future house according to their own wishes. After selecting a house type, for example, the floor area, roof shape, front door, terrace or even the furnishing style can be customized. Building specifications and architectural limits in the configurator ensure that in the end there is always a concept that can actually be implemented. Maximum transparency can also be offered through the configurator: The fixed price of the house including land price, as well as the financial effects of the individual adjustments are displayed directly. This gives the builder a clear insight into the cost structure in advance.

Further optimization on the digital twin

Once the house has been configured, the model can be passed directly to the construction engineers. It can be transferred directly to Building Information Modeling (BIM), where it is displayed as a digital twin with all geometric and material-specific information. This offers further optimization possibilities for a fast construction process and clear recommendations for the best and most economical material solution. In Borna, the calculations led to the choice of large-format system wall elements made of autoclaved aerated concrete. Short construction times and very good thermal insulation properties were the most convincing arguments in favor of our Ytong and Silka products. In addition, the production of the components for the interior and exterior walls can be carried out serially despite the individual design, since the floor plans are planned in a grid of 25 cm. In BIM, it is easy to calculate how many m³ of building material are needed to create the solid walls. Cost and processing times are thus also calculated as accurately as possible.

Fast assembly times thanks to digital planning

When BIM is used, everyone involved benefits - from the client to the construction team on site: full cost transparency thanks to material and time savings, very fast assembly times, less waste and a high quality of execution. The combination of digital construction management and large-format components enables particularly fast implementation.
Construction costs are significantly reduced compared to the conventional approach through standardization, without having to cut back on individual design options. This is particularly important for new housing developments like the one in Borna, in order to be able to offer young families attractive properties at competitive prices.
