Standardised building in housing construction and economical construction methods / Standardisiertes Bauen im Wohnungsbau und wirtschaftliche Bauweisen

Building prices and construction costs for housing construction in Germany are growing dynamically. The main cost drivers are still legal, normative and other regulations that are generally drawn up at federal level. However, the trend in building prices also shows that intense building activity is also affecting prices. This trend is also complex: the trend in the groups of trades concerned with carcass work can be categorised between the rate of inflation and increased building prices. The price trend in the whole of technical completion, on the other hand, is disproportionate, and it is these completion trades (heating, ventilation, sanitation and electrical) that are actually driving construction costs. Building materials for primary construction of our residential buildings are also developing at different rates. Masonry falls within the sphere of the general growth rate of prices, while reinforced concrete and wood are much higher. This overall trend shows the finiteness of supposedly simple solutions for accelerating the rate of construction in housing construction. Serial building can only offer a niche solution. Far more intelligent is the use of standardised construction, i.e. repetition of ideal ground plans, development types and standardised buildings that can be adapted to the conditions at each site. Furthermore, it is clear that the use of masonry construction in a multi-floor residential building is still the most economical type of building to construct in Germany.
