Professional Refurbishment: More Value, Efficiency & Comfort
A professional refurbishment is the most effective method to increase your property’s value, drastically reduce energy costs, and adapt your living comfort to modern standards. Whether it’s an energy-efficient refurbishment of an older property, a complete renovation, or the modernization of individual areas – a refurbishment is an investment in your future.
But many owners hesitate, facing three central questions: Where do I start? What will the house refurbishment cost? And what funding can I claim? ATLAS HAUS is your transparent partner who clearly answers these questions. We show you how the correct sequence not only ensures a smooth process but also directly reduces your costs.
House Refurbishment: The Right Sequence for Costs & Funding
The most important takeaway first: The correct sequence for your house refurbishment is the key to maximizing subsidies. The very first step should always be a professional energy consultation and the creation of an Individual Refurbishment Roadmap (iSFP).
This document, funded by BAFA (Federal Office for Economic Affairs and Export Control), analyzes your house’s current condition and defines the most sensible refurbishment steps. The iSFP is not just a checklist for your house refurbishment; it is the prerequisite for the valuable iSFP bonus – an additional 5% funding bonus on many measures.
A typical, energy-sensible sequence often looks like this:
- Energy Consultation & iSFP Creation: Analysis, defining measures, and securing the iSFP bonus.
- Building Envelope (Insulation): First, heat loss must be stopped. This includes roof insulation, facade insulation, and replacing old windows.
- Building Systems (Heating): Only after the house is insulated is the new heating system sized. (Installing a new heating system in a “leaky” house would be inefficient).
- Interior Fit-Out: Bathroom modernization, electrics, and other modernization or renovation work.
This structured approach ensures that you not only avoid structural damage but also optimally meet the requirements for maximum “house refurbishment funding.”
Refurbishment Funding (BEG): Use KfW & BAFA Optimally in 2025
You don’t have to bear the “house refurbishment costs” alone. The Federal Funding for Efficient Buildings (BEG) offers significant grants and loans for energy-efficient refurbishment. ATLAS HAUS advises you on the complex applications.
The funding is mainly split between two institutions:
BAFA (Federal Office for Economic Affairs and Export Control):
- What? Non-repayable grants.
- For what? For individual measures (BEG EM), e.g., insulation, window replacement, and heating optimization.
- Your Benefit: Can be combined with the 5% iSFP bonus.
KfW (Reconstruction Loan Corporation):
- What? Low-interest loans.
- For what? Often, as a supplement to BAFA grants (e.g., Loan 358/359) or for complete refurbishments to an “Efficiency House” standard.
A loan for your house refurbishment often becomes cheaper through this funding than a normal bank loan. We help you submit the applications correctly before the work begins.
What Does a House Refurbishment Cost? Costs per sqm
The “complete house refurbishment costs” depend heavily on the year of construction (e.g., 1950s vs. 1970s) and the current condition. Flat-rate prices are not reputable. To give you a realistic orientation, nonetheless, here are typical industry estimates for key measures. These “house refurbishment costs per sqm” are guidelines and often already include insulation and installation.
Indicative Refurbishment Costs (Estimates)
| Refurbishment Measure | Estimated Costs per sqm | Notes (Source: Industry Analyses) |
| Roof Insulation | €40 – €300 / sqm | Depends on insulation method (e.g., between rafters) and material. |
| Roof Re-covering | €50 – €150 / sqm | Often carried out in combination with insulation. |
| Facade Insulation | €20 – €200 / sqm | A wide range, depending on the system (e.g., ETICS vs. blow-in insulation). |
| Window Replacement | €500 – €800 / window | Price per unit, incl. triple-glazing and installation. |
| Bathroom Refurbishment | €3,000 – €5,000 / sqm | Very high range depending on fittings and new plumbing. |
| Electrical System Renewal | €70 – €170 / sqm | Unavoidable in a core refurbishment (new wiring, fuse box). |
| Heating System Replacement | €8,000 – €30,000 (Total) | (Not per sqm) Highly dependent on technology (e.g., heat pump). |
These figures serve as an initial estimate. You will receive a detailed “complete house refurbishment cost” breakdown from us after a thorough on-site assessment.
Refurbishment vs. Renovation: An Important Difference
While a renovation (or “house renovation”) primarily involves cosmetic repairs (e.g., painting, replacing floor coverings), a refurbishment is a more profound intervention into the building’s fabric. An energy-efficient refurbishment specifically aims to reduce the house’s energy consumption and is the prerequisite for the funding mentioned above.
