Plan your house with granny flat, i.e. with a second housing unit, and benefit from many advantages

House with
granny flat

An additional granny flat in your new home can be used in various ways.

Whether as a living space for the grandparents, one’s own children or for renting out, the second housing unit creates flexibility and can potentially make a valuable contribution to home financing.

Our tip

“The ‘Energy Efficient Construction’ funding programme of the Kreditanstalt für Wiederaufbau applies to each housing unit in a home. Thus, for a finished granny flat, you can take advantage of an inexpensive loan and repayment subsidy a second time.

In this way, the amount that can be financed through KfW can be doubled very simply from the current 100,000 to 200,000 euros, and the repayment subsidy will amount to up to 30,000 euros (KfW Efficiency House 40 Plus).”

Granny flat
in an extension

Is a granny flat directly inside your house not really your cup of tea?

We have the right solution for you:

With our Variant 25-150 with granny flat, we have simply attached the additional flat as a Cubus house to the main house – compact, at ground level and barrier-free.

A rented out granny flat is tax deductible

Tax advantages
of a granny flat
