House Design
Who designed it:
- designer from a construction company
- based on the floor plan of a pitched roof house by a South German ecological prefabricated wood construction company
What do you particularly like? Why? Seating window and the staircase dividing the living-dining area, open ground floor, discreet upper floor
What do you dislike? Why? Storage space might be tight, utility room possibly too small
Price estimate according to architect/designer: not yet known
Personal budget limit for the house, including equipment: –
Preferred heating technology: air-to-water heat pump

If you had to give up, on which details/extensions?
- could you give up: KFW 55 standard, T-solution in bathroom, kitchen island, if good reasons: possibly rotate the straight staircase 180 degrees to access it from the hallway
- cannot give up: in our opinion, the design does not reflect exaggerated demands already

Why has the design ended up like it is now? For example:

What makes it particularly good or bad in your eyes? The garden is important to us. In our opinion, the rectangular footprint is better suited than a square one to get the optimum out of the plot (sun on the west terrace). The floor-to-ceiling window on the south side in the kitchen.

What is the most important / fundamental question about the floor plan, summarized in 130 characters?
The ground floor is nicely open and cozy and connects the garden and terrace with the house, while the upper floor offers enough privacy both inside and protection from outside views. We searched a long time for the optimal plot and want to use the land as the garden ideally as a retreat, with a possible swimming pond / pool later and a small vegetable garden.

And I’m surprised—eleven pages of posts and no one has mentioned what a terribly dull building this is?
It looks like a construction site container used in large projects.

No, don’t be surprised.

Personally, I don’t find the house attractive either. The OP mentions Bauhaus. This is not Bauhaus. With Bauhaus, ALL details have to be right: proportions, materials, execution, floor plan—the entire concept.

It’s not my style either, but you can assume that a) the cube shape was desired and b) due to budget constraints, there are no recesses or projections.

I think the house would look much nicer/cozier with a pitched roof...

That’s already been addressed—why a pitched roof is not an option.

Thanks, it’s more of a cube style than Bauhaus – it was late last night when I started the thread, so I can’t change or edit it now.

We plan to use wood elements or Trespa for the facade. The 3D rendering doesn’t show these details yet.

There are still ten different windows, and nothing in the facade shape detracts from that. The attic parapet, as the only structuring element, further emphasizes the container construction impression.

There are certainly bigger construction issues with this building than the facade. But yes, the mix of window styles is unusual, and generally, some of the placements are rather odd.

Yes, we’ll see... above, only parapet windows; below, large fixed glazing plus floor-to-ceiling casement doors, a lift-and-slide element, and probably the window seat. The design is more about maximizing the number of windows while just barely meeting KFW55 standards.

Then please also plan proper shading. Otherwise, it will turn into a greenhouse.
