Further wishes/special features/daily routine, also reasons why this or that should or should not be:

- large open living/dining area, orientation of these rooms to the south.
- large terrace in front of the house accessible from kitchen/dining area
- garage not in front of the house, as this would lose the sunny spot :) --> for this, driveway north next to the house
- as little roof pitch as possible on the upper floor
- possibility to later reduce the living room and set up a bedroom (planned door in front of guest WC)
- rather small TV area, as we are not typical couch potatoes :-D
- office with dormer
House Design
Who developed the plan:
- Do-it-Yourself: template from a prefabricated house provider
What do you particularly like? Why?: house set back 10m from the street, large living area because large family visits often
What do you not like? Why?:
- possibly kitchen too small
- possibly too little storage space
Price estimate according to architect/planner: appointment pending
Personal price limit for the house, including equipment: 350,000 (planned own contribution: electrical, floors, heating, water)
Favored heating technology: geothermal, possibly solar thermal as support

If you have to do without, which details/extensions
- you can do without:
- access from living room to outside
- you cannot do without:
- terrace access

Why did the design turn out as it is now? For example
- Everything was accommodated on the ground floor and there is later the possibility to create an additional room by a wall in the current living room (door in front of guest WC in living room)
- large terrace in front of the house is important and has space

What is the most important/basic question about the floor plan summarized in 130 characters?
Are there problems with the size of the utility room if washing machine, dryer, technology, and storage space are to be accommodated?
Is the guest WC with shower sufficiently large?
Do the room sizes appear reasonable?

I never understand why living rooms are planned so tiny and dining areas so huge. A table for eight people but a sofa for a maximum of three? That doesn’t make sense to me. And maybe it’s because I dealt with morning sickness for a long time and with the kids, stomach flu viruses visit more often than the parents-in-law – the toilet would be way too far from the bed for me. I’d rather plan a getaway route style. :)

9 sqm for the living room and almost 32 sqm for the dining area,...? Especially during longer dinner parties, sooner or later everyone ends up on the sofas with us. As a family, we also live in the living room and not at the dining table.

The site plan lacks information on roads and other developments. Therefore, I cannot imagine how the house and the garage will be accessed.

That is correct, the living room is really small in comparison. I think with the open layout you are not tied to the shown furniture placement. The sofa could also be moved further towards the dining table.

Very good point regarding the distance. We have to rethink that.

The site plan lacks information on streets and other buildings. Unfortunately, I can't picture how the house and the garage will be accessed.

Important information forgotten, it is a new development area. It is currently being developed. I have accordingly supplemented the site plan with the draft plan for the development.

Garage on the street. Is the garage/carport allowed on the neighbor's boundary? Is a distance to the street required?

The idea of placing the two bathrooms on top of each other is commendable but architecturally the implementation is nonsensical. It can be done better, at least more advantageous for the living room.

With your square meters, you are quite generous. Then the budget is not sufficient.

It can be smaller and much better. Then it could also fit the budget. Are 2 children planned?
