20% margin possible through intelligent topping up

Berlin is growing and urgently needs more living space!

But how can this demand be met without taking up more floor space?

The solution lies in the sustainable addition of floors to existing buildings.

This efficient method can create up to 410,000 square feet of housing.

1. sustainability

The addition of timber frame construction to the apartments is an important contribution to sustainability.

Wood is a renewable resource that requires less energy in the production of wooden modules and therefore emits less CO2 than conventional construction with concrete.

In addition, wood stores the carbon dioxide absorbed during growth, which is why building with wooden modules is particularly advantageous from a climate protection perspective.

2. efficiency

Adding a new attic improves efficiency gains from an energy perspective, especially for unrenovated existing buildings.

By avoiding composites as far as possible and reusing materials, a high degree of circularity can be ensured.

3. cost advantage for inventory holders

Despite increased construction costs, the expansion is profitable for existing owners due to the promising rental potential!

According to PriceHubble, the achievable cold rents for topped-up apartments in Berlin can range from €14.50/m² in locations far from the city center and up to €28.00/m² in the city center.

In addition, the city of Berlin can actively promote and financially support rental housing construction.

4. avoidance of soil sealing                                                                

Elevating existing buildings offers the opportunity to create additional downtown living space without further soil sealing.

This approach is relevant in terms of achieving the 30-acre goal.

The target states that soil areas in Germany may be sealed at a maximum rate of 30 hectares per year.

This helps to preserve the environment and conserve natural resources. It also supports the preservation of green spaces and the promotion of urban recreational opportunities.

5. more cost effective

From an urban planning and cost perspective, the addition of more floors and the redensification of apartments will always be the most cost-effective option.

The modular timber construction methods offer monetary advantages compared to conventional construction. The short planning and construction time as well as the use of prefabricated modules accelerate and simplify the construction process, which significantly relieves the budget.

Thus, the IRR can be additionally increased, which can be measured with the PROBIS calculate module.
