Extensions are structural additions to an existing real estate object. This can be, for example, a storey or an extension. Extension buildings are distinguished from new buildings, reconstructions, conversions or modernizations.

A strong driver of innovation in the digitalization of construction planning, and thus also of extension construction planning, is Building Information Modeling (BIM). Here, a three-dimensional digital twin is created to simulate and analyze the dynamic behavior of a property under different conditions.

In addition, AI can be used to increase efficiency and safety in the construction industry. Here, computer programs continuously learn from input data and perform their tasks more and more efficiently, and processes now run automatically.

With raw materials becoming more and more expensive, 3D printing is emerging as a possible solution to this problem. It also allows the construction time to be reduced many times over.
