We plan to build a single-family house with about 125sqm (1,345 sqft). We would like to include a small home office on the upper floor.

We prefer not to have the staircase directly next to the front door to avoid having to walk through the “dirty zone” all the time. However, an L-shaped staircase next to the front door might save space. This would allow for a larger utility room (the front door would be moved slightly).

The kitchen cabinet layout is not finalized yet. A place for a fireplace is also still missing (the challenge is integrating the chimney on the upper floor).

House Design
Designed by: > Do-it-Yourself
What do you particularly like? Why? What do you dislike? Why? The north and west elevations look a bit odd; maybe an additional window should be added there.
Personal budget for the house, including fittings: approx. 250,000€
Preferred heating system: Gas or air-to-water heat pump

Why is the design like it is now? For example:
We used various floor plans from prefabricated house providers/contractors found online as templates.

What is the most important/basic question about the floor plan, summarized in 130 characters?

The following questions:

1. Is the floor plan feasible and practical to use?
2. Would an L-shaped staircase be preferable to save space?
3. Do load-bearing walls on the upper and ground floors have to be aligned?
4. Where is the best place to position the carport on the plot, northeast or northwest?
5. How can the chimney for the upstairs fireplace be integrated without taking up too much space?

Is it possible to add another 20cm (8 inches)?

No, that was correct. I meant the ground floor layout looks very similar regarding the arrangement of the WC, utility room, and cloakroom. See:

Hello Katja, great design.

I like the ground floor even more, especially since it moves toward a more square shape and therefore the hip roof feels more balanced. But that might just be because it’s hard for me to imagine a long, narrow urban villa. Usually, those types of houses are more rectangular and tend to have a gable roof rather than a hip roof. (Although, for us, the roof style isn’t set in stone; it could also be a gable roof in principle.)

Did you have specific cabinets in mind for the kitchen on the north side? Because they can’t be too deep.

What I don’t like as much is the relatively large hallway on the upper floor compared to the other design. A straight staircase just doesn’t leave many options.
Could you also tell me the interior dimensions of the cabinets on the upper floor?

What do you think about the idea of adding another room on the ground floor? Here’s another example from BärenHaus (YOUNG FAMILY 125 WALMDACH) with a net floor area of 125 m² (1,345 sq ft), measuring 8.6 x 9.09 m (28.2 x 29.8 ft):

In addition to the office and guest room on the upper floor?
How many (dream) rooms do you want in total?
It’s all quite tight and complicated to navigate. It might look common enough for you in the sketch, but for a collection of rooms, a 125m² (1,345 sq ft) layout is not really suitable.

But it might simply be because I find it hard to imagine an elongated city villa.

So for you, does a "city villa" necessarily include a hipped roof (more precisely a pyramid roof, without a ridge)?
Stefan890 schrieb:
Usually, those rather rectangular houses have a gable roof instead of a hipped roof.

It’s actually the other way around: a gable roof “requires” a rectangular footprint that is not square, because a square shape would appear narrower due to perspective distortion.

If you look closely, it turns out to be a leftover area just reclassified as a room, while there is a utility room next to it with a lower standard compared to the housekeeping room. It’s not really a gain.
