Dear fellow contributors,
I’m sharing our first attempt at the floor plan. Unfortunately, I can’t fill out the list because copying it over on my phone doesn’t work properly, sorry.

Key data:
5 children between 0 and 11 years old
2 adults in their mid-thirties
Plot of about 900 sqm (9700 sq ft), facing north
Building window edge on the street side: 17.35 m (57 ft)
Sloped site; within the building window, the ground rises about 2 m (7 ft) over 10 m (33 ft) from front to back

We want 5 small children’s bedrooms, a slightly larger office for working from home, a master bedroom, three showers, three toilets, a bathtub, and access to the garden through the living room on the upper floor. One wall in the children’s rooms should be removable later.
The attic is walkable.

We are allowed to build 2 full stories, with a ridge height of about 12 m (39 ft) and an eave height of 11.6 m (38 ft).
We would prefer a hip roof.
The current drawing is 9.5 by 11 m (31 by 36 ft), but we would like to have around 195 to 205 sqm (2100 to 2200 sq ft) of living space later; garage or storage will be added.
The back wall of the house is embedded up to about 2 m (7 ft) into the slope.

I will try to attach a rough overview of the plot.

Move the walls on the north side to the left.
Did you notice that because of the wide staircase on the north side, you only have rooms measuring 2.50 meters (8.2 feet)? I think this is disproportionate. In the center, you therefore have a wider area for accessing the rooms than the rooms themselves on the north side. 2.50 meters (8.2 feet) compared to 4.00 meters (13.1 feet)...

Basement level with bathroom from the upper floor and staircase shifted toward the west. Problem: the hallway at the back becomes too narrow. I probably need to adjust the children’s rooms a bit more.

And upper floor with the same changes

@Arifas ... you mentioned a hip roof as your preferred roof style in the opening post. However, from the photos of the area, I only see gable roofs. Would a hip roof be permitted?

If not, a gable roof will do as well. We tend to be practical.
The neighbor four houses down also has a hip roof. I don’t recall the roof type being required. I’ll ask the architect next week.

I agree . But it could work without it.

@Nordlys I would like to hear your opinion, since you seem practical and experienced from my point of view: is building with 30cm (12 inches) Ytong blocks acceptable, or does it have to be KfW55 standard with 36cm (14 inches) blocks and an additional cost of 18,000?
