Storey Addition to KfW 40 Standard: More Living Space, Maximum Funding
Do you need more space but don’t want to leave your familiar surroundings? A storey addition is the intelligent solution for creating new, high-quality living space – right on your own property. With Atlas Haus, you can make this dream a reality not only quickly and efficiently but also very economically: as a high-quality KfW 40 house built to the most demanding standard, securing you attractive government funding.
Why a Storey Addition is the Smart Alternative to a New Build
A storey addition offers decisive advantages over purchasing a new plot of land. You gain valuable living space and benefit from a sustainable, fast construction method.
- More Space Without Moving: Expand your home for a new children’s room, a home office, or a separate living unit without giving up your familiar environment.
- No Land Costs: You build on your existing foundation, saving the high costs and effort of buying land.
- Sustainable and Fast: Thanks to modern timber frame construction, the new floor is assembled in the shortest possible time. This conserves resources and minimises construction time on site.
- Increased Property Value: An additional, energy-efficient floor significantly increases the market value of your house.
Our modern timber frame construction often exceeds the energy requirements set for a conventional KfW 55 modular house, ensuring you greater living comfort.
The KfW 40 Standard: Quality That Pays Off in the Long Run
A storey addition as a KfW 40 house means investing in the highest construction quality. This future-proof standard far exceeds the minimum legal requirements and represents a significant energy improvement over an older KfW 55 house. For clients with the highest demands for energy self-sufficiency, there is also the option of achieving the KfW 40 Plus standard, often implemented as a prefabricated KfW 40 Plus house with its own power generation and storage. Regardless of the level chosen, thanks to excellent insulation of the building envelope and modern building technology, your heating costs will drop noticeably. You will enjoy an optimal indoor climate all year round and make an active contribution to climate protection.
Secure Government Funding: How to Maximise Your Benefits
The government rewards energy-efficient construction in existing buildings. The KfW 40 house funding is a significant advantage, as a storey addition is considered an energy-efficient renovation, giving you access to the most attractive KfW programmes. With the “Residential Building – Credit 261” programme, you not only receive a low-interest loan but also a high repayment subsidy that you do not have to pay back.
| Efficiency House Level (Renovation) | Max. Loan per Residential Unit | Repayment Subsidy (Share) | Max. Repayment Subsidy |
| EH 85 | €120,000 | 5 % | €6,000 |
| EH 70 | €120,000 | 10 % | €12,000 |
| EH 55 | €120,000 | 15 % | €18,000 |
| EH 40 | €120,000 | 20 % | €24,000 |
Note: When using renewable energies (EE Class), the loan amount increases to €150,000 and the repayment subsidy increases by an additional 5%.
