ᐅ Planning a 130 sqm single-family house on a 500 sqm plot of land

Hello,

we have been juggling ideas back and forth for several days now and would appreciate some fresh external input.
The plot is already owned, and the house has been purchased from a major general contractor (134 sqm (1,444 sq ft)).
We are maximizing the zoning plan, meaning we cannot build larger or taller.

Besides optimizing the floor plan, we are still considering the positioning of the house.
It is an excellent plot with a 3 m (10 ft) wide access path, so we only have to keep 3 m (10 ft) distance on all sides.
Two parking spaces side by side would be ideal, but I would prefer not to risk ending up just 3 cm (1 inch) too close to the neighbor.
Alternatively, we could arrange them in tandem or enlarge the "front garden" and convert it into parking space.

The house could be rotated if that helps.

Zoning Plan / Restrictions
Plot size: 500 sqm (5,382 sq ft)
Slope: no, almost perfectly flat
Site coverage ratio (floor area ratio): 0.2
Floor space index: 0.4
Building window, building line, and boundary: 3 m (10 ft) distance on all sides
Border development: none
Number of parking spaces: 2
Number of floors: 1.5
Roof type: gable roof
Architectural style: classic
Orientation: N/E
Maximum heights/limits: ridge height 8.8 m (29 ft), eaves height 4.3 m (14 ft)

Homeowner Requirements
Style, roof type, building type: single-family house
No basement
Number of occupants: 2 adults + 2 children
Room requirements ground floor: 70 sqm (753 sq ft), upper floor: 60 sqm (646 sq ft)
Family use with small office/guest sofa
Guests per year: 5
Conservative construction
Open kitchen with island: yes
Number of dining seats: 6
No fireplace
Music/stereo wall: yes
Carport

Guest WC with shower
Small walk-in closet in master bedroom
Small pantry
"Open" walk-in shower upstairs without door between 3 walls, toilet somewhat hidden, large washbasin/mirror (3 women at home...)

House Design
Planning origin: modified catalog house
What do you particularly like? Why? All desired rooms included, open-plan living area as the heart of the ground floor, equally sized children’s rooms
What do you not like? Why? How to distribute everything sensibly? Small walk-in closet affected by roof slope
Cost estimate from architect/planner: not applicable, as already purchased
Preferred heating technology: air-to-water heat pump

If you have to give up, on which features/extensions
-Can you give up: pantry, storage room upstairs
-Can’t give up: equally sized children’s rooms, open kitchen, office, guest WC with shower

Why is the design as it is now?
Example: standard design from the general contractor

What is the most important/basic question about the floor plan summarized in 130 characters?
How can we optimize the layout (adjust walls, windows, doors)?

Thank you very much for your suggestions!

Best regards,
Ruska

My guides should actually still be pinned at the top regarding house placement or how to approach the planning. For a medium-sized plot, I would draw everything around it. Everything. And do it nicely with a pencil, so you can still see later what you have already tried out and erased!

Regarding parking spaces arranged one behind the other. I have not found any prohibition against placing parking spaces in a row either in Section 12 of the Land Use Ordinance or in our local development plan. In another new development area, parking spaces have also been approved in this way. Well, we are in Rhineland-Palatinate, so maybe the rules are different here.

We are planning it that way as well.

Regarding parking spaces, I would simply suggest checking with the city or local municipality. They are the ones who make the final decision. It doesn’t depend on the state or region and can vary from place to place. Here in our town, there are many parking spaces where you have to reverse back onto the street. That’s exactly how it was approved for us as well.

Yes, as far as I know, this is regulated by state law.
A parked parking space is not considered a full-value parking space. If only one parking space is required, it is up to you to build additional ones in a row, since the one needed space is approved.
However, in my opinion, there are many allowances for what can be built that make little practical sense, and a parked parking space with the required vehicle is definitely a nuisance if you’re not good at playing Tetris.

Clearly the wrong approach. If the plot is tricky, the house must be designed according to the plot, not the other way around by buying a house and trying to fit it in somehow. Moving walls around hardly helps.

130 sqm (1400 sq ft) without a basement for four people is already quite tight. A standard floor plan is not an option then.

Next time I would do it differently; now it can’t be changed. But I don’t think the plot or the house are that bad.

Not 10 meters (33 feet) wide.

To be honest, I also have trouble following the sketch and seemingly rough, approximate measurements of the house (9.51 is not 10). I also can’t see the difference for the exterior walls at 49 cm (19 inches). When you have very limited space or the plot restricts a typical single-family home, you have to refine the design down to 10 cm (4 inches), stay open to possibilities, but also plan buffer zones: plaster thickness to garden fence, hallways in bedroom and dressing area... according to your information, the dressing room and bedroom wouldn’t even work here for me.

Then tell us which house and provider you’re dealing with.

Flair134, the dimensions are practically copied 1:1 from the original floor plan. There may be minimal deviations. The internal dimension is 9.52 m (31 feet 3 inches) with an external dimension of 10 m (33 feet). A 1 cm (0.4 inch) error over 10 m (33 feet) is 0.1%, which neither a laser measure nor a tape measure can do better than 😉

You should first plan 10 cm (4 inches) for a fence and an additional meter (3 feet) for a hedge... your computer sketch doesn’t allow precise planning, nor does it give the viewer a sense of the plot size. That also applies to the owner and planner. Also, a vehicle does not have the same width as a carport, so you should plan a path between car and house...

The site plan is pixel-perfect and drawn to scale, with the parking space each 3 x 5 m (10 x 16 feet), which corresponds to standard dimensions of a single carport.

Of course, there will still be a garden!

In the latest site plan, there is a 13 x 18.8 m (43 x 62 feet) garden area beyond the house edge with a 5 m (16 feet) front yard. How far north would you move back, and why?

At the moment, I only see a major annoyance and planning failure regarding the vehicle fleet, which will cause frustration due to frequency, duration, and thus limited use of the plot. This will also reduce the resale value...

Site_plan_new2 is drawn to scale. I’m grateful in advance for a more skillful proposal.

It may be pixel-perfect, but it is not a site plan: it only shows the layout of the house, parking spaces, and so on on the plot, but NOTHING about the location of the plot within the cadastral area. There is no indication of its relation to the street, neighboring properties, green space corridors, or anything like that. This is not usable.
