ᐅ Single-family house – approximately 150 square meters – without a basement – Any ideas? Thanks.

First of all, thanks for your comments in my last thread. It was planned as a three-family house, but now we are starting over and just want to build a single-family house for ourselves.

A few details about the plot (there is still an old building on it, which will be demolished, see property 24):

- 1170 m² (0.29 acres)
- no slope, flat
- site coverage ratio & floor area ratio (I’m on the road and need to check these later)
- next to it is a carpentry workshop and the carpentry’s storage hall; a 5 m (16 ft) building setback must be observed.

Number of occupants:
- Parents with 3 children (10, 8, and 3 years old)

Our wishes:
- Guest toilet with shower and a large bathroom
- One kitchen (possibly open plan) with lots of natural light; my wife runs a cooking channel on YouTube
- Two stories (preferably) or as few roof slopes as possible
- Roof style = gable roof? (we definitely want it to be a usable attic, possibly for us or the children)
- No basement
- Brick cladding on the exterior
- Carport or garage; we’re still flexible on this…
- Possibly a guest room/office on the ground floor
- Possibly a granny flat / secondary unit? In case we’re alone at some point and the house becomes too big for us…

My architect is currently on vacation; he will take care of it when he returns… and when the design is ready, I will post it here.

Questions:
- Do you have any additional ideas on what I should consider or specify?
- We like this sample plan (see attachment). What do you think of it? (The attic is not included, the room layout fits well.)

I appreciate any useful comments .... (probably also a matter of taste)

PS: The plot scale is 1:500

Ground floor plan: open kitchen, dining/living area, office, hallway, WC, utility room, stairs.


Upper floor plan: bedroom, walk-in closet, bathroom, hallway, 2 children's rooms, stairs.

The Berlin attitude always comes from the heart, even if you don’t hear it in writing—“in standard German.”

You also have to be able to read criticism. And then it says, quite constructively:

1) The economy town villa floor plan is designed for one less child.

2) Trying to fit it into a steeper roof will be a Pyrrhic victory in terms of cost compared to the traditional method of simply increasing the floor area sufficiently.

3) If the architect considers this floor plan a solid basis, they would fail the test of “a good architect must be able to set the client straight.”

Yes, that’s exactly what I was asking.
Because not everyone is comfortable with adding a dormer to a city villa.
It tends to look a bit unusual.

You have to think about these kinds of things.
Usually, you can’t just take a floor plan as is; several details need to fit.
Why don’t you build a house with 3 children's rooms instead? So without the roof option? It’s generally better to have everything on two floors!
However, 150 m² (1,615 sq ft) with 3 children’s rooms is already quite tight!


It’s all new territory for us…. Since we’re building without a basement, our idea was to find storage space somewhere—so the attic came to mind, possibly with an additional bedroom. We haven’t looked into how feasible that is yet.

Regarding the square meters… that was just a rough estimate… what would you consider the minimum? 180 m² (1,938 sq ft)? (We can’t rule out having a fourth child in a few years.)

Thanks!!

@tumaa ... you seem to misunderstand. The floor plan you posted typically fits with a relatively shallow hip roof.

A cross-section would look roughly like this:

Simple side view of a house with a gable roof and dimension of 2.0 m


As you can see, you barely get 2 m (6.6 ft) of height, and that’s only in a simplified line drawing without insulation, etc. So: these types of roofs are not suitable for living space, and only conditionally for storage.

That’s why I suggest considering other house shapes that usually feature gable roofs.

Unfortunately, there are no dimensions on the floor plan ... the kitchen seems a bit tight, especially if YouTube recordings are planned there.

A key factor for finalizing the floor plan is also knowing how deep the building setback (building permit / planning permission) area is on the plot.

I once asked the building authority about the roof shape: any type can be used. Whether it fits is another question.

I checked the documents again:

Building zone according to land use ordinance: GE
Site coverage ratio (floor area ratio): 0.8
Floor space index (floor area ratio): 1.2

Building 24 will be demolished... what about the light gray parts of the building?

Is access possible from the west and south? To the east, there is a 5 m (16 ft) distance... is that just for the house or also for a garage?

Could you please provide the approximate width and height of the plot?

Do you mean a granny flat? So you would live there yourselves and rent out the main house?

We have a building footprint of approximately 10 x 10 m (33 x 33 ft), with 2 full floors. The ground floor includes a shower (having 2 showers in the house is advisable for 5 people). On the upper floor, there are 3 children's bedrooms, each at least 16 sqm (172 sq ft), and a pitched roof with a spacious attic, which is necessary if you don’t have a basement and where no one would want to live in summer due to the heat.
