House design
Who designed the plan:
- planner of a construction company according to our ideas

Price estimate according to architect/planner: not yet known
Personal price limit for the house, including equipment:
Preferred heating technology: air-water heat pump

What do you particularly like? Why? We would really like the recess in the house visually, but we are very uncertain whether this makes the kitchen/dining area too compressed and too small. We tend to "expand" it again just to have a rectangular house with a bit more space.

Why is the design the way it is now?
Design from the house planner based on our sketches/ideas

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

Does the plan work the way we imagine? We are concerned that the kitchen/dining/living area seems too compressed.
We want an open/spacious living feel with bright rooms in the living area.

A few opinions/assessments on the plan would be nice :)

PS: the latest attached plans are missing the north arrow, so I have additionally attached an earlier planning draft with a north arrow.

Welcome!

We want an open/spacious living feeling with bright rooms in the living area.

Hmm, the dining area is already too small on the plan and the access to the living room through "anteroom"/kitchen/dining is suboptimal.
(I didn’t look more closely at the rest for that reason…)
Addition: Upstairs looks quite okay at first glance. ;)

Personal price limit for the house, including equipment:

Could you please add that? After all, you are building with a basement… the budget can quickly become tight. Then something will have to be cut.

We want an open/spacious feeling in the living area with bright rooms.

I think you will get that feeling through the large window areas. Nevertheless, the dining/kitchen area is actually not spacious, but sufficient.

Overall, the floor plan will work well. The hallway situation is a bit unfortunate with the many corners. Hardly any space for furniture (upper floor). But there are worse things. Also, the direct line of sight from the dining area to the guest WC is not great, but the distance is sufficient.
Will the shower on the upper floor get a shower door? Otherwise, the toilet will get too wet.

However…

Office: Home office; possibly as a bedroom in old age

… the office is not suitable as a bedroom in old age. It is practically not furnishable with wardrobes, or it will become very cramped… at most for one person.

The current plan is supposed to allow for a separate residential unit on the upper floor (granny flat/separate apartment) as well as living on the ground floor in old age.

… the shower WC is also very small, therefore not age-appropriate. I would accept that size of a main bathroom in a student apartment, but not otherwise.
On the other hand, the upper floor apartment has a comparatively large bathroom for a single/couple apartment (?), which does not appear very attractive without an exit.
Apparently, you are fond of placing storage rooms in the middle of the heart of the designs, so somehow there will always be slalom around and hallway corners and therefore unnecessary traffic space present. The floor areas compete with the desired spaciousness.

I would start again without later apartment separation and then go more rectangular and not place storage rooms in the “energy flow zone.”

YPG has already written everything.

Who are you building with?

If children are only planned, you are probably still young? Why plan for old age already, which will most of the time be a compromise? For example, pipes would also have to be laid upstairs, and it would be a bet on the future that one of the children moves upstairs. I usually see strangers less often in the [OG-Wohnung] in such constellations.

First of all, thank you very much for your feedback!

Could you please add that?

Our budget planning foresees <600k.

Hm, the dining area is already too tight on the plan

As mentioned in the OP, we are also tending to remove the recess in the house here to ease the situation between the kitchen and dining area.

Does the shower upstairs get a shower door?

Definitely yes :)

… the office is not suitable as a bedroom for old age. It is basically not furnishable with wardrobes, or it will get really cramped… at most for one person.
… also, the shower toilet is very small, therefore not age-appropriate. I would accept this size of the main bathroom in a student apartment, otherwise not.

Okay, thank you very much for the two points, that already makes sense. We need to think about that again..

Apparently, you are determined to place storage rooms right in the heart of the designs, so that there will always be slalom somewhere in and around corners of corridors and thus unnecessary traffic areas

From our point of view, the "storage rooms" arose in order to still make reasonable use of the resulting large traffic areas in view of the residential units to be separated and the associated separable staircase.

On the ground floor, we also deliberately wanted the living area "around the corner," and not aligned with kitchen and dining, which in houses we have visited so far usually gave the feeling of standing in a narrow corridor.

Why plan for old age already, which will be a compromise most of the time?

We would like to plan ahead or together for old age, since we currently are not inclined to build multiple houses :)

Who are you building with?

The current planning was done with a family-run company operating regionally in the western Augsburg area; whether we will build with the company is not yet fixed.

Thanks again for your constructive criticism and suggestions!
