One building, one team, one fixed price

Owners and investors in the Ruhr area often do not want to manage five firms, but one contact. Corpus Bau refurbishes apartment buildings as a joined-up package: roof, facade, windows and insulation – planned by our architects and engineers, carried out by our own tradespeople.

After surveying you receive a fixed price and a construction schedule. We agree any changes in writing before extra work is done.

What the package includes

• Roof
• Facade with external thermal insulation composite system
• Windows
• Insulation of the basement ceiling
• Scaffolding and disposal
• Coordination of trades and a fixed site management

Heating, interior fit-out and bathrooms are not included in this package. We can take on interior fit-out and bathrooms as an extra if you wish, for example flat by flat when a tenant changes. We can bring a new heating system into the overall project; it is not one of our own trades.

What such a package costs

As a guide price after a site visit we calculate about 178.602,79 € net, or 212.537,32 € gross, for a typical apartment building in the Ruhr area with eight flats and about 512 square metres of living space. That is around 22.325 € net per flat. It is an orientation from our sample calculation, not a fixed price and not a catalogue price.

For orientation: the roof is about 239,20 € per square metre, the facade about 196,04 € per square metre, one window about 1.159,32 €.

After surveying you receive a written fixed-price quote for your building. The price depends on condition, layout and the exact number of windows.

Funding for several flats

The exact amount always depends on the individual case.

For the building envelope there is a grant of 15 %. Eligible costs are 30.000 € for the first flat, 15.000 € for the second to sixth and 8.000 € from the seventh. With an individual renovation roadmap these limits rise to 60.000 €, 30.000 € and 15.000 €. The extra 5 % applies only to the part above the normal limit, not to the full costs.

For a building with eight flats, 121.000 € is eligible without a renovation roadmap – up to 18.150 € in grant. With a roadmap the limit rises to 240.000 €. The extra 5 % applies only above 121.000 €.

The tax bonus under § 35c Income Tax Act (20 % over three years, max. 40.000 €) applies only to owner-occupied houses, not to investors. It is an alternative to the grant, not on top of it.

You receive the required certificate through us.

You can complete a funding check even before the viewing.

Who this is for

• You own an apartment building in the Ruhr area and want to renew facade, roof and windows in one go.
• You want a fixed price after surveying, not an open bill across many separate trades.
• Your tenants should experience one construction phase if possible, not several firms one after another.
