What is the most important/basic question about the floor plan in 130 characters?

Due to the sloped plot, it is not really possible to build a terrace with a view. Therefore, the living area moved to the upper floor, and for summer, we thought sitting on the balcony would work. However, the balcony as drawn seems too small. Would it make sense to use the garage roof for the balcony? (a rough 3D draft is attached)

The original design planned the heating/utility room in the garage. Because of the edge development regulations and additional insulation needed for this room, it was moved to the ground floor. As a result, a bathroom had to shift upstairs to the upper floor, where a storage room had to be removed. We fear there will be too little storage space overall. Do you see it the same way?

Note: Since we are still in the planning stage, not all views are up to date. At the very beginning, the upper floor was shifted in relation to the ground floor. Also, the garage wasn’t directly placed on the plot. I have attached the views anyway to show the orientation. The satellite photo also shows the earlier status.

Swap the dressing room and bedroom, and remove one bathroom door. Then it will fit.
Exchange the staircase with the storage room; the kitchen will fall into place. Please make sure the toilet is not visible from the living areas.
The window combinations in the basement look poor.

Why is the house positioned so far to the northeast on the lot? I'm having trouble understanding the attachments, but wouldn't it be possible to place it further west to significantly shorten the driveway (and probably the utility connections)?

Having the bathroom on the upper floor visible—and surely audible—from the living area is quite unusual. A “quiet retreat” feels different.

In my opinion, the storage and utility rooms are far too small.

As Yvonne already mentioned, either swap the walk-in closet and bedroom or remove the closet entirely to enlarge the second child’s room. Load-bearing walls can probably span 2 meters (6.6 feet) to the right—I don’t think that would affect the wall above. That’s practically just a room divider on the upper floor—drywall maybe?

We’ve already discussed the chimney on the upper floor. I would recommend consulting with the chimney sweep to check if it is long enough to create proper draft.

That statement doesn’t seem clear to me based on the elevations and so on. The slope actually drops away from the living room. So it should be quite feasible to have a nice seating area in front of the house.

The original design planned to locate the heating/technical room in the garage. Due to issues with building close to the property boundary and the need for additional insulation in this room, it was moved into the ground floor.


I would have considered that the better option as well. In the end, it’s a choice between insulating a heating room extension to gain living space on the ground floor, or having a balcony plus living space on the upper floor. Probably not much difference cost-wise, but for the layout I think the first is the advantage. Or are there other obstacles to the extension?

Hello everyone, thank you for your replies

Our living areas are downstairs and the bedrooms upstairs.

The slope runs from northeast to southwest. The neighbors are directly on the southwest side. We thought about placing the bedrooms on the ground floor since there’s no view from there anyway. The view is only available at the upper floor level. That’s why we want to have our living spaces and the terrace/balcony there.

Looking only at the upper floor, I would move the staircase towards the southwest and place a storage room behind it accessible from the kitchen. I would completely rethink the ground floor.

I like your idea to move the stairwell; that would allow us to reconsider the ground floor. The problem with the ground floor is that rooms not necessarily needing daylight must be on the northeast side. Due to the slope, no windows can be installed there. That means the bedrooms for child 1 and 2 must be on the southwest or northwest side. Hmm, that’s difficult. I would actually like to move the front door, probably only possible if we give up the walk-in closet and rearrange the rest.

Our initial plans had the house rectangular, then it became square.

Is it possible to see your floor plans somewhere here in the forum?

- You’re right, definitely need to remove one bathroom door
- If I swap the stairs with the storage room, I’m worried the sauna downstairs won’t fit anymore, right?
- We want to keep the upstairs bathroom as small as possible by moving the wall upwards towards the northeast so that it’s somewhat "hidden." Then a cabinet or something similar on the side in front of it.

- What do you mean by window combinations? The arrangement or the selection of large and small windows? (probably both)

We would like to do that too, but there is an easement on the plot. A water supply pipe route runs along the western part with a 3-meter (10 ft) protective strip on each side, so moving further west is unfortunately not possible.

We thought an upstairs WC is necessary because, on the one hand, we don’t want to burden guests with always having to go downstairs, especially as most activity happens upstairs. On the other hand, the office will be used as a guest room and the bathroom is right next to it. If the WC were downstairs, we might unnecessarily wake the child in the evening. But you’re absolutely right about the “quiet spot” comment. As I wrote to ypg, we would move the bathroom upstairs. Do you think that would be somewhat acceptable?

The small storage rooms will definitely be a challenge

There is basically only a partition wall upstairs – drywall?

I need to check that with the structural engineer. No drywall is currently planned.

The slope goes down from the kitchen towards the dining room. We don’t want a terrace downstairs mainly because of the “view” issue. From downstairs, you look directly at the neighbors, but from the upper floor level you look over them.

I will discuss insulation again with the roofer. I thought if we have to insulate the heating room, we might as well insulate the entire garage roof. That would lead to a high construction. If the garage roof is also used as a balcony, this height would have to be considered for the rest of the balcony as well. That would be expensive and the height would have to be included in the floor construction on the upper floor so that the balcony can be accessed more or less barrier-free from upstairs. Although the garage height could be adjusted... well, I’ll definitely talk to the roofer. Or is it possible to insulate rooms from underneath the ceiling with insulation panels?

The slope declines from the kitchen towards the dining room. The reason we’re not putting a terrace below is more about the “view” issue. Down there, we look directly at the neighbors, but from the level of the upper floor, the view goes beyond them.

Of course, everyone has their own priorities. I have to say, though, that for me the connection of the living space to the garden is more important than the view. It feels like a bit of freedom when I can just open the balcony door from the kitchen and step onto the lawn.
You can still enjoy the view from the upper floor.

I would plan the heating room as an “extension” to the house, not attached to the garage. This way, it can be thermally separated. I would probably also plan an entrance there, so there’s more space left on the ground floor.
How it will look in the end is a different matter.

I prefer living spaces facing the garden over rooms with a better view.

Not the final floor plan.

Arifas has bedrooms on the ground floor.

Keep an eye on the additional construction costs.
