Building a house with a granny flat

An additional living unit offers a degree of flexibility. For example, a granny flat can be used as a first home for children, potentially as an accessible retirement home for parents, or rented out to help finance the property. Planning for a granny flat is also advantageous for home financing . The prospect of additional rental income improves affordability and thus the application for the best possible financing, saves on taxes, and supports you in terms of amortization.

Another advantage is the flexible use in old age . For example, you would have the option of renting the granny flat to caregivers or living in the apartment yourself.

What needs to be considered when building a house with an attached apartment?

Generally, when building a house with an attached apartment, the building regulations of the respective municipality and zone apply. The permitted development potential of the building plot is particularly crucial. This specifies how large the house, or rather the living space, may be in relation to the plot area.

Do you have a building plot in mind, or are you interested in one of our detached houses with building land? We would be happy to clarify the feasibility of a house with a granny flat for you.

When planning a house with an attached apartment, we strongly recommend a separate entrance to ensure greater privacy for both residents. The apartment's finish should also be carefully considered to ensure it can be easily rented out later. Therefore, the kitchen, bathroom, and floor plan should ideally meet current market standards. If the budget for the house construction is limited, the apartment can initially be built as a shell, allowing for interior finishing at a later date.

Whether the granny flat is located on the upper floor, the ground floor or, in the case of a sloping site, in the basement, thanks to our architecture department we can create an individual preliminary project tailored to your needs.
