House Design
Planner: Architect based on our room and style requirements (bright, open, modern)
What do you particularly like? Why? We like the overall design since our small plot limits the size. We wanted a large, beautiful living and dining area that also serves as the main living space. The children should have rooms about the same size (quite a distance apart, but still equal). The attic is planned as a retreat for us, with its own bathroom including a potential small sauna to create a nice ambiance. We are planning in the Rhine-Main area and live somewhat rural, so we want an unobstructed view of nature from our bedroom (hence the balcony).
What don’t you like? Why? Overall, we are very satisfied and, based on the valuable guidance in this forum, developed our own ideas early on. We only needed three rounds with the architect to finalize the plan. We would have preferred a straight staircase instead of two quarter-turn staircases, but after the first draft, we gave up on that because it would have taken up too much space.
Cost estimate according to architect/planner: $540,000
Personal price limit for the house, including fixtures: $650,000
Preferred heating technology: Ground-source heat pump with underfloor heating and photovoltaic system

If you had to give up on something, which details or features
- could you live without: We are not at this point
- cannot give up:

Why is the design the way it is? For example:
As mentioned above, our plot is limited in size and we also want to keep some green space. Our architect considered all requests and gave us honest and open feedback on ideas (e.g. open gallery in the entrance area up to the upper floor – which we decided against).

What is the most important/basic question about the floor plan, summarized in 130 characters?
We are very happy with the plan and almost all of our wishes are met. Still, we would love to hear your opinions and ideas, especially based on your experiences and how it works in practice.

Let’s set the topic of professionals aside – it was an architect with 30 years of experience.
Have a proper design created with measurements; that’s something an architect can definitely do. By the way, a draftsman can do this even better; what you have uploaded so far as a floor plan is practically nothing— even I could manage that, and I usually get frustrated when I have to draw something.
No one here wants to annoy you; we’re happy to help, but the floor plan you’ve drawn is not really usable at this stage.
Since the floor plan will change anyway, the drawn exterior facade is just a rough sketch.

I like the floor plan, especially considering the small plot of land. In the living area, I’m having a hard time picturing the sofa corner because it looks like a fireplace will be installed there. I think the floor-to-ceiling window in the hallway is a good idea; otherwise, you would have a dark corridor. Are you planning to leave the basement stairway open? It might not look very nice when viewed from the living room.

Best regards,
Sabine

Regarding windows and doors:
... here the pictorial notation is generally preferred over the textual one.

My wife just came up with the idea to add two dormers in the attic, one each for the bathroom and the walk-in closet (on the stairwell side). I’m not sure how that would look and I’m unclear about the costs.
Costs might be the lesser issue here. And of course, I assume she means dormer windows.

For a 260 sqm (2800 sq ft) plot, you first need a site plan showing the surrounding area... then a floor plan draft... otherwise, any discussion is purely theoretical.

Also, a draft without doors and windows is not really helpful... if you can even call it a draft at all.

Unfortunately, doors are no longer included here, but some will be added and we already know where.

At the end of the hallway there should be a floor-to-ceiling window.
We don’t have a detailed plan with the kitchen and furniture, but it is already “arranged” in our minds.

Attached is the exterior view. Just imagine the bay window on the side removed, as it no longer exists.

The design itself might be okay if you consider many assumptions and guesses, but since we are in the dark here, we don’t really know anything. Also, guessing seems to be pointless for us. Therefore, any advice or attempts to put ourselves in the situation are simply lost efforts.

Oops! — if that wasn’t a typo, we might have to reconsider not only the bay window but also the garage.

If I understand correctly, the windows and doors were simply not included in the images shown to us, for whatever reason.
