Hello everyone,
I now need to decide on a roof pitch and knee wall height and wanted to ask for your recommendations, especially whether the additional costs are really worth it. What should I consider when choosing the roof pitch?
It is a gable roof.
150 sqm (1,615 sq ft) house, 1.5 storeys
Knee wall 1.00 m (3.3 ft) instead of the standard 0.75 m (2.5 ft): €4,005
Knee wall 1.20 m (4.0 ft) instead of the standard 0.75 m (2.5 ft): €6,320
Knee wall 1.50 m (5.0 ft) instead of the standard 0.75 m (2.5 ft): €9,805
127.4 sqm (1,371 sq ft) house, 1.5 storeys
Knee wall 1.00 m (3.3 ft) instead of the standard 0.75 m (2.5 ft): €3,775
Knee wall 1.20 m (4.0 ft) instead of the standard 0.75 m (2.5 ft): €5,915
Knee wall 1.50 m (5.0 ft) instead of the standard 0.75 m (2.5 ft): €9,125
Knee wall 1.00 m (3.3 ft) instead of the standard 0.75 m (2.5 ft), with a simultaneous change of the roof pitch to 38° (instead of the standard 40°) costs only €3,000

Hello,
are you still unsure about how large your house should be, or why you have different square meter measurements? Otherwise, I would suggest sketching it out or planning it on a computer. This way, you can also see the different exterior views. There is quite a big difference between a knee wall height of 0.75m (2 ft 6 in) and 1.50m (5 ft). Have you visited different show homes to take a look? That will definitely help you with your decision.
Best regards,
Sabine

Since the monthly cost for the first planned house with a hip roof was a bit too high for me, I have now requested two new quotes, each 20,000€ to 25,000€ cheaper.
The net floor area according to DIN 277 is the same for the gable roof with an eaves height of 0.75m (2.5 feet) and the house with a hip roof, but that makes about a 25,000€ difference.
That’s why there are two different sizes: 127.4 sqm (1371 sq ft) would be enough for us (we currently live in a 93 sqm (1000 sq ft) 3-room apartment without sloped ceilings), but 150 sqm (1615 sq ft) is of course ideal, especially 150 sqm (1615 sq ft) with a hip roof.
Is there perhaps a website where I can enter and plan something like this? We have already looked at several model houses, but they always had either pyramid roofs, hip roofs, or shed roofs.

It also depends on what you want to use the attic for. If it is going to be used for storage because there is no basement, it makes sense to have a steeper roof pitch. My house is planned to have two full stories later and a shallow 25° (25°) gable roof. This means the height in the middle of the attic is only about 2m (6.6 feet). With a steeper roof, I would have had to add knee walls. The cost difference would not have been significant because the roof area decreases with a shallower roof.

My house is planned to have two full stories and a shallow 25° (25 degrees) gable roof. This means the attic’s height in the center is only about 2m (6.5 feet). With a steeper roof, I would have needed a knee wall. The cost wouldn’t have changed much because the roof area decreases with a shallower roof.It not only depends on the intended use of the attic but also on personal preferences, the zoning plan (building permit / planning permission), and the budget.
For example, we decided from the start that we wanted two full stories. Of course, these are more expensive than a partial story with a knee wall – and we planned accordingly. Some people prefer sloped ceilings.
If the zoning plan had not allowed it, we would have settled for the maximum permitted knee wall height.
Everyone answering your question will recommend their personal preference.
Based on that, I recommend: two full stories, and if that is not possible, the maximum allowed knee wall height.
The height of the knee wall should also be adjusted to fit the furniture you want to place against the sloped walls. A knee wall height of 1.5 meters (5 feet) is great, but it’s not enough for a wardrobe—though it works well for a chest of drawers.
The higher the knee wall, the larger the attic floor area becomes where you can stand, if you plan to convert the space.
You need to comply with the building permit / planning permission, as not every knee wall height is allowed.
