ᐅ Window Sill Height in Kitchen and Living Room

Hello,

I have a question regarding the sill height for windows on the ground floor.

First, it concerns the kitchen window. According to the floor plan, a sill height of 100 cm (39 inches) is planned. With a screed thickness of about 18–19 cm (7–7.5 inches), that leaves only around 80 cm (31 inches) for the countertop height if it should not extend above the window sill. We are currently planning a countertop height of 90 cm (35 inches).
Calculation example: screed/floor 20 cm (8 inches) + countertop 90 cm (35 inches) = minimum sill height of 110 cm (43 inches)?

Furthermore, a sill height of 100 cm (39 inches) is also planned for the living room. After subtracting the screed/floor, about 80 cm (31 inches) remains. The shorter side of the corner sofa (backrest height 68 cm (27 inches)) will be placed in front of the window wall (window width 3.01 meters (9.9 feet)). We are unsure if this height will work well and would appreciate your assessment. The other windows on the respective walls will be adjusted accordingly, so no need to address those.

Thank you!

Before or after Christ, with or without VAT: it is always the same complaint that when specifying sill heights, it is often missing which reference “zero height” they relate to.

A sill height of 100 cm (40 inches) above the finished floor level is actually good – if the sink is within the window’s swing range, I recommend a higher sill height in the kitchen or at least a fixed lower window section; this is also practical for kitchen herb pots. Many builders also extend the countertop into the window reveal instead of installing a separate windowsill.

Are we still talking about https://www.hausbau-forum.de/threads/efh-ca-140-m-2-Kinderzimmer-was-haltet-ihr-vom-Grundriss.28383/page-6#post-279674 (#33)? – then take the sill height of 100 cm (40 inches) above finished floor level and “adopt” the sill height of 125 cm (49 inches) at the WC window as the top edge of the fixed lower section.

Thank you for the assessment.

Really difficult – we put a lot of thought into it, and the result is… okay.

I would extend the countertop into the window sill and design the lower part of the window as fixed. When planning the exact dimensions, I recommend getting some help, as this can be a bit tricky!

We have the window sill positioned a few centimeters above the countertop. This leads to the following consequences:
We could have used those extra centimeters for the window size because with a width of 1.5 m (5 feet), two sashes, and a fixed lower part, there isn’t as much glass area left as I had expected.
The small wooden section between the work area and the window sill doesn’t look very nice and should ideally be covered up since it’s quite sensitive (we painted a wallpaper protector on it).
Pro: the window sill can be used separately, so, for example, you won’t get bread crumbs on it that need constant clearing and cleaning.

Also: we made the mistake of matching the window sill height in the dining room to the kitchen. From a seated position, you can’t really look outside – I find that unfortunate (when the windows were installed, we first asked about the cost of changing this, but it was too expensive for us).
So, I would plan the window sill behind the sofa a bit below the backrest height. That way, you don’t have to look at a wall, window sill, and frame when sitting on the sofa.

Thank you for sharing your experience! Since I couldn’t find a topic like this through the search, I hope it will be helpful for many others.

Yes, unfortunately the search function is not a highlight of this forum.
