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

However, it should also be considered that roof windows will be positioned quite high with a knee wall of 1.5 meters (5 feet), making cleaning, opening, and looking outside more difficult. While additional windows can be installed below the knee wall, this will increase the overall cost.
