House Design
Planner:
- Do-it-yourself; adapted by planner to the site
What do you particularly like? Basically everything needed is included; the sloping site makes it a bit more complex; driveway to garage is almost level as is the terrace; the view facing south is nice
What do you not like? Why? Upstairs bathroom is too small; would like walk-in shower and bathtub; widen the building by one meter (3 ft)?
Personal budget for the house, including fittings: 550,000
Preferred heating system: underfloor heating

Hello everyone,
We have a nice plot with a slight slope and want to build a new home. All rooms are basically included in the design, but we would appreciate other perspectives. The upstairs bathroom seems too small at the moment, and the layout feels unbalanced.

Then the other rooms on the upper floor become too small. And what about the cold basement with open staircases?

Are you building a stairwell around the staircase from the basement to the ground floor?
It looks open according to the plan.

Either a stairwell for the basement stairs, with the stairs to the upper floor above it as well.

The upper floor won’t be too small. You have potential in the hallway and bedroom.

Don't worry too much about it. You have to zone smartly here: different wall designs in both areas, possibly different lighting concepts.

I would consider that if it’s an existing building or if walls are being removed in an old building to enlarge the space. Or if a guest room has to be made slightly narrower. When building new, you ensure that everything fits together harmoniously so that you don't have to rely on effects.

But there is absolutely no need to think any further about this, since the floor plan is completely inconsistent.

You are right about that. However, one must strongly point out the obvious inconsistencies to the original poster here.

And here we go again: the bedroom has full south and west exposure. You won’t get more heat into a room than that. Ultimately, every window will have to be shaded when the sun is shining.
I recommend orienting the bedroom to the east.
If you do that, other things upstairs will adjust accordingly.

The hallway doesn’t just look awkward due to the two opposing staircases; it’s also larger in terms of space than the living room. Is that reasonable?

In the basement, I wouldn’t have the staircase open into a cold room. Instead, I would create a small hallway at the bottom and a wall to enclose the staircase.

I would insulate the basement rooms.

The utilities need to be installed anyway, so you can do the rest then. This will be your private entrance. Keep it warm and make it appealing. An open staircase leading upstairs feels cozier than a dark corridor with a door at the top that is heavy and hard to open when carrying things.

I would plan a landing staircase along the upper wall.

The problem with the bedroom is that the neighbor is to the east; to the west there are no buildings, so it is oriented in that direction. You can usually keep the bedroom shaded during the day without any issues, right? After all, you spend most of your time there in the evening or morning?

What do you mean by the hallway in the basement? What would it look like? Does the technical room need insulation? When insulating the basement, is it done from the outside, inside, or both?

The living room should be about 40 m² (430 sq ft); hopefully, the hallway isn’t that large.

You generate heat in the utility room, and your water supply must be protected from freezing.
That is why utility rooms are usually located within the thermal envelope.

Despite the sloping site, we have a basement living area with only one side against the ground. The wall is insulated on both sides to prevent condensation.

Create a comfortable and pleasant staircase so you don’t feel like you are crawling out of the basement.

Your hallway plus the two staircases require at least 20 square meters (215 square feet).

What will happen to the bathroom that is drawn in but no longer exists?
