Hello everyone,
after quietly reading for some time, I am now hoping for your help.
Almost three years ago, we bought and renovated a bungalow from the 1970s (not an energy-efficient renovation). Since the ground floor now meets our needs, it is time to focus on the attic.
And this is where you come in.
The attic is basically already developed, but not in the way we imagine it.
We want one bathroom with a shower, one master bedroom, and one or two children’s rooms.
Unfortunately, I don’t have dimensioned plans; the exterior measurements were taken from the ground floor plan. The other data were measured by myself and therefore are probably not 100% accurate.
I am mainly looking for creative input and ideas for the room layout. I have attached my first draft/idea.
Important details:
- Concrete ceiling
- Roof pitch 35 degrees
- Two wooden beams and the chimney/vent are fixed and cannot be moved (marked in white)
- Windows as they are
- Wastewater outlet located to the left of the stairs in the exterior wall
- The white lines outside are meant to mark the 1 meter (3 ft 3 in) line, which will become the new knee wall
- The roof shape surprised us somewhat because where the white line for the knee wall is drawn, the large roof is actually recessed into the smaller roof on the inside, which in my opinion makes the smaller roof less usable
What do you think of my idea? Is it feasible or not? Will the rooms/functionality work out well?
Do you have suggestions for improvements or maybe a completely different idea?

First of all, wow, great sketch. Excellent.
Haha, yes, I think that’s the fundamental problem here (and I’m sure some users are already cringing, at least inwardly), but that was how it was.
We went through the rooms, thought about what we wanted and could change. Then we had an on-site meeting with a structural engineer (who also said the plans were only moderately suitable for assessment). We discussed everything with him; he found our plans unproblematic, and we proceeded. I know this isn’t really forum-compliant, but it works for us.
Accordingly, the windows: we don’t want to change them. They can’t be made wider because there is already very little space between the top corner of the window and the roof slope, and I really don’t like floor-to-ceiling windows. Maybe roof windows (skylights) could be considered. That said, the windows currently present in the rooms at the gable ends are perfectly adequate (unless you’re thinking of a new build?).
As for the plan, there actually is a centimeter-accurate plan of the current rooms upstairs 🙂. Only the exterior dimensions might be slightly off, since you can’t measure behind the knee wall to the outside wall.
Copying the ground floor plan is a) difficult because it’s not A4 size and b) as mentioned, the original is already in poor condition and hard to read, copying it won’t improve that.
In the printed ground floor plan you can see there is indeed a knee wall/storage space. I don’t know if there are different ideas about it, but part of the room is boxed off (with wood and paneling), as you can see by the different room sizes currently.
The bathroom, if you look at the plan with the name facing you to the right, is the third room. First, there’s the large one with windows on the gable side, then the stairs (around 2.8 by 1 meter (9 by 3 feet), I think), and then the room that is only two meters (6.5 feet) deep (due to the large knee wall)—that’s the bathroom.

You wrote there is a bathroom in the attic, where exactly is that?
Has the knee wall already been built?
I tried to sketch it out using your information.
It’s not that easy to plan exactly as you imagine.
The first step for the designer is to take precise measurements down to the centimeter. Since we can’t do that here, you have to provide them.
Place the ground floor plan on a copier so at least something to scale can be seen. When copying, don’t cut off the dimension chains.
Then take the copy and draw in the existing parts. For example, knee wall to knee wall—that should be dimensioned precisely in centimeters. The height of the knee wall is also very important.
I have added the exterior dimensions, wall thickness, chimney, wooden posts, stairs, and windows. This shows that when the wall is on the axis, there are only about 3 meters (10 feet) on each side to the knee wall.
This results in a passage between the wall and chimney of 1 meter (3 feet), and between the chimney and the 2-meter (6.5 feet) line only 0.5 meters (1.5 feet).
The windows are very small; you won’t get much light into the rooms like that. Ideally, windows should cover about one-eighth of the floor area. A 3 by 4 meter (10 by 13 feet) bedroom already only has about one-twelfth.
These rooms really need at least double casement windows and/or floor-to-ceiling windows.
Exact measurements are required at this stage; otherwise, it’s hard to provide useful advice.
Your best option is to see a designer who can at least draw up the current layout.
Then you can think about how to implement your ideas.
How did you renovate the ground floor? All without a plan?

I would definitely move the bathroom closer to the stairs. Avoid planning a walk-in closet that is enclosed.
I would also add a skylight window to the children's room.Thank you as well. In this case, I am actually considering whether the children's room should be placed on the south side after all. It would then be adjacent to the bathroom, but that is usually not a dealbreaker.

Please provide the sill height and the total window height.
You can now try to draw the existing layout into my sketch.Sorry, I didn’t see any new posts for some reason.
So, the sill height is 81 cm (32 inches) and the window height (up to the top of the wall) is 1.40 m (4 ft 7 in).
I have now marked the existing layout using Paint (was that what you meant?). Especially the measurements around the chimney are not 100% accurate because there are some recesses, but I think this should be enough for orientation.
