ᐅ Clear ceiling height and window height. Provider’s standard: 262.5 cm

Hello, we are currently planning a house with a gable roof (38°) and are unsure about the ceiling height for the ground floor. The standard offered by our builder is a structural height of 262.5 cm (103.5 inches) / clear ceiling height of 246 cm (97 inches). The floor-to-ceiling windows are 226 cm (89 inches) tall. Now we are considering raising the ground floor by either 12.5 cm (5 inches) or 25 cm (10 inches). However, we also have a relatively high knee wall of 150 cm (59 inches) (possibly 137.5 cm (54 inches) might be an option or make more sense).

Here are the questions:

1) Will the eave height become too high overall with the increased room height and the high knee wall? On the long side, we have no windows on the upper floor (currently no strip windows either), so it will be a large closed area. Is there a way to visually break that up?

2) Do the windows need to be raised as well, or are 226 cm (89 inches) still suitable?

Additional info: Our living room (including dining and kitchen) is quite large (about 11.5 x 4 meters (38 x 13 feet)), so we are concerned that a low ceiling might feel oppressive, hence the idea of raising it.

Perhaps someone has experience with these ceiling heights and can offer some advice.
Thank you!

I’m trying to adjust the floor plan to make it a bit wider and slightly shorter...
Here is the original floor plan:

Wasn’t this the final result after weeks of discussion:

Floor plan of a house: rooms such as bathroom, hallway, bedroom, child room 1, child room 2, storage room, staircase.

Floor plan of a residential house: living/dining/kitchen, foyer, guest room, stairs.


A clear ceiling height of 2.46m (8 ft 1 in) is really the minimum standard nowadays. Common ceiling heights are around 2.60m (8 ft 6 in). In smaller houses, 2.55m (8 ft 4 in) is also acceptable. A room longer than 11m (36 ft) with only 2.46m (8 ft 1 in) height will definitely feel like a bunker.
If the ceiling is raised, the staircase has to be bigger. Then the windows should also be enlarged accordingly.

Have you ever considered integrating the roller shutter/blind box into the facade? That way, you don’t need a lintel at all and you get maximum brightness in the rooms

What do you mean by facade? We have recessed boxes that are about 25 cm (10 inches) high. Our windows now reach up to 238.5 cm (94 inches) above the finished floor level, with a room height of 275 cm (108 inches) above finished floor level, so the boxes just barely fit under the ceiling.

I agree with you! That’s why we increased it by about 12.5 cm (5 inches), so now it’s around 2.58 m (8 feet 6 inches). The windows were also raised by 12.5 cm (5 inches). But I think this topic is already quite old and the planning has already been finalized.

I meant integrating the boxes into the facade, meaning where the insulation is placed in front of the bricks, if you have any.

The windows and roller shutter boxes come as one unit and are installed into the fixed opening. I estimate the insulation will be placed in front of the roller shutters (22 cm deep (8.7 inches) with a brick depth of 24 cm (9.4 inches), so it should fit).

What advantage would there be to integrating the boxes into the facade—would it allow the windows to be installed higher? I think integrating boxes into the facade is practically not feasible.
