What options are there for integrating a granny flat into your new home? And which one best suits your wishes and your property? To give you an initial overview, our architects have prepared sample designs for you to draw inspiration from. Use these suggestions as a basis for your individually planned house with granny flat or realise your ideas with us completely freely.
The following floor plans show how a granny flat can be planned in a single-storey extension. This variant is particularly popular for houses without a basement. One major advantage is the spatial separation of the main and granny flat. It is also easy to create a separate area in the garden for both parties. With the extension, the floor plan of the main house only needs to be minimally adapted compared to a conventional detached house.
The following floor plans show how a granny flat can be integrated directly into the building structure - a good solution for plans without a basement where no extension is desired or possible. The second residential unit is accommodated on the ground floor and can still have its own entrance. The advantages: A compact structure without an extension reduces heat loss. In addition, extending the main floor plan is usually cheaper than an extension.
The following floor plans show how a granny flat can be accommodated in the basement of a detached house on a slope. In this way, the basement, which is often necessary on sloping plots anyway, can be utilised sensibly and additional living space can be created with plenty of natural light from up to three directions. The advantage: the main house and the granny flat are spatially separated and can be planned with their own entrances.
The planned size of the granny flat, the conditions on the plot and the way in which the second residential unit is to be integrated - all of this influences the floor plan of a house with a granny flat.
Our eleven tips for the perfect floor plan tell you what else you need to consider when planning: from the optimal orientation of the house to possible requirements from the development plan.
- A granny flat is an additional flat of secondary importance (and therefore less space) in a home.
- A separate front door is not mandatory, but a lockable flat door is essential.
- A granny flat has its own sanitary facilities as well as cooking and sleeping facilities.
While the floor plan of a house with a granny flat is no different from the planning of a detached house in many respects, there are a few points that you should definitely bear in mind. One of these is the decision as to how the granny flat should be integrated into the house. A number of factors must be taken into account here, which are often mutually dependent:
Planning a floor plan with a granny flat in the basement or on the ground floor
- If the house is to be built on a slope, it usually makes sense to plan the granny flat in the basement of the floor plan, as a basement has to be built anyway and it can be supplied with daylight from three directions due to the slope.
- If a house is planned on a flat plot with a basement, the question arises as to how to get enough sunlight into the granny flat in the basement. For example, the ground in front of a wall can be dug away to create a kind of terrace. The resulting large window areas provide daylight.
- Does the floor area specified in the development plan even allow for a granny flat on the ground floor or will the built-up area then be too large?
- If the house has to be planned without a basement for other reasons, the question becomes superfluous.
The type of cohabitation should be taken into account in the floor plan
- How much do you want to see of the other party's life?
- Should there be a shared entrance or separate entrances?
- Can the garden be shared or would it make more sense to separate the rooms?
- Are there any problems if some rooms such as utility, storage or laundry rooms are to be shared?
There are a few facts to consider here
- Do you want to rent out the granny flat or use it yourself (e.g. as an office)?
- Who do you want to let the granny flat to? If the grandparents are to move in with you, you can plan the cohabitation differently than if the granny flat is intended for a carer or is simply rented out as an additional source of income to a permanent tenant or to holiday guests.
- Will the type of use change over the years? For example, initially as a rental and later for grandparents?
- If you are thinking of selling the property again, you should consider whether your floor plan is suitable for the largest possible target group or whether it is very specifically tailored to a small number of possible uses.
