ᐅ Floor plan of a 200 m² single-family house, raised ground floor, existing plot, double garage

Created on: 6 Feb 2025 23:45

Dear collective wisdom,

We would like to build our single-family home on the parents-in-law’s property. The target is about 200 m² (2,150 sq ft) with a double garage. Our architect is very creative, which we find somewhat unsettling, so I’m seeking advice here.
Plot size: 1200 m² (13,000 sq ft), our portion will be approximately 550 m² (5,920 sq ft) in the future
No slope present → farmland (1549) but lies 1 m (3 ft) below the plot
Floor area ratio unknown
Site coverage ratio unknown
Building envelope, building line, and boundary unknown
Surrounding development unknown
Number of parking spaces: 1.5
Number of floors: 2
Roof shape: no specifications
Architectural style: no specifications
Orientation: no specifications
Maximum height/restrictions unknown
Other conditions
Existing setback areas must be reapplied for

Owner requirements
Architectural style, roof type, building type
Classic single-family home with a pitched roof
Basement, floors
No basement, two full floors
Number of people, ages
5 people, 33, 31, 2, 0 (planned)
Space requirements on ground floor and upper floor

Office:
Home office P1 4 days + P2 2 days
Guest bedrooms per year
None
Open or closed layout
Open
Conservative or modern construction
Modern
Open kitchen, kitchen island
Open kitchen, U-shaped
Number of dining seats
Minimum 8, ideally 10
Fireplace
Wood stove (optional)
Music / stereo wall

Balcony, roof terrace
No balcony, roof terrace (optional)
Garage, carport
Double garage, extra wide/deep (7.5 x 9 m (25 x 30 ft))
Utility garden, greenhouse
Utility garden
Additional wishes / special features / daily routine, including reasons for preferences
Due to flooding events, the house should be built 1 m (3 ft) above ground level; garages may remain at ground level
Existing building requires more parking than the existing double garage, at least 3 spaces
Garages on the east side because parcel 1560/6 has a continuous 10–12 m (33–39 ft) tall tree/bush line on the boundary

House design
Do-it-yourself
What do you particularly like? Why?
Ground floor: Open living and dining area; kitchen is directly integrated into life at the table
Ground floor: Pantry between work area and kitchen serves as an acoustic buffer
What do you dislike? Why?
Ground floor: TV with stereo should ideally face the table to fill the whole room with sound
Upper floor: Too convoluted; children’s rooms are under 15 m² (160 sq ft)
Upper floor: No space for drying/ironing laundry
Garage: Technical room would be flooded during high water
Estimated cost according to architect/planner:
750,000 euros
Preferred heating technology:
Heat pump

If you have to forego, which details or features could you do without?
- Roof terrace
- KfW 40 standard (energy efficiency standard)
- Wood stove
- Large garage
- Utility garden
- 15 m² (160 sq ft) per child’s room

Which features are indispensable?
- Three children’s bedrooms
- Home office
- Open living area
- Second bathroom

Why is the design as it is now?
A mix of many examples, trying to save square meters and fit everything into 180 m² (1,940 sq ft), but now we are happy to build larger since permission up to 272 m² (2,930 sq ft) was approved.
What wishes were fulfilled by the architect? None yet; he has only provided proposals we don’t necessarily like.
What do you consider particularly good or bad about it?
We like the ground floor layout; technical areas cause little noise inside as they are separated.

The plot plan originally anticipated reusing existing prefabricated garages; however, these have been sold, so we have a free hand.

Because your 507 sqm (19.5 x 26 m / 64 x 85 ft) minus 117 sqm (19.5 x 6 m / 64 x 20 ft) driveway leaves 390 sqm (4,198 sq ft). And you want to cover that with 100 sqm (1,076 sq ft) of building footprint plus a double garage plus AB. That doesn't leave much. Sorry, hardly anything.

Yes, that is really tight for such a large house. I made a sketch with this layout.

Because of the large garage, the building is pushed very close to the parents' house. The west-facing terrace is actually quickly shaded in the evening as a result. Is that really ideal?

Thank you for your effort. My wife also spent some time on it this afternoon and tried to draw something that comes close to what you made.

Very nice. What scale are you using? What does one square represent? Or how many squares should make up one meter?
The next step would be to position the house on the plot, graphically.

I can’t say much about the roof; our architect doesn’t know the maximum building height allowed. He would base it on the preliminary decision and not go beyond that. This would result in a building height of 8m (26 feet). With at least 50cm (20 inches) clearance from the ground, that leaves 7.5m (25 feet) usable? Is the roof really usable at that height?

What does the preliminary decision say about this? If only the 8m (26 feet) height was specified, only that will be reviewed. How tall are the neighboring houses?
That’s definitely something you should follow up on.
Why? You have to build the roof anyway. The space beneath it will always exist. Making the ceiling structurally sound and insulating the slopes does cost something, but it’s cheap compared to the gain in usable area. Or put another way: not using the huge space under the roof is a waste. However, to make use of it, you do need a certain pitch and height.

The next step would be to position the house on the plot. Graphically.

25cm (10 inches) corresponds to one square. Although the exterior walls are 50cm (20 inches) thick, for simplicity they didn’t want to be more precise.

That really might be something to follow up on.
Why? You have to build the roof anyway. The area underneath naturally comes with it and simply exists. Making the ceiling load-bearing and insulating the sloped ceilings does cost, but it’s cheap compared to the additional usable space you gain. Or put differently: not using the huge area under the roof is a waste. But for that, you will need a certain slope and height.

There’s nothing mentioned about height, only that the building must blend into the local architectural style and that’s why it is approved.
The house is slightly raised on the plot. This was probably deliberately mounded at the time to accommodate a basement. As a result, the existing house stands higher compared to the surrounding houses. I can’t say exactly how much, but at least from the gable window, I can see the roofs of the neighboring houses.

How can I lead a staircase to the upper floor? That only works if the staircase is placed in the middle again, right? Otherwise, I won’t fit under the roof slopes at all, will I?

Do you mean the attic?
It depends on the roof pitch. At 20° you don’t need to build a staircase. You wouldn’t be able to stand there anyway. That’s why the question about the total height comes up.

Here is an example with a 35° roof pitch:

The house is raised by 50cm (20 inches). The ridge height is about 9.50m (31 feet).
You immediately notice how everything relaxes. Presumably, further optimization could save a few more centimeters. I didn’t really push this part. If necessary, the layout can also be rotated with the terrace on the west side. I wouldn’t do it myself. But that would require the height.
