Open attic in Tuscan house

But I would like to keep 2 bedrooms on the ground floor (age-appropriate)

As drawn, this refers to young, dynamic sports students with a tendency towards asceticism...

Explanation I would like to build a two-generation house, i.e. an apartment for me and my husband with a bedroom and shower bathroom on the ground floor, as well as a guest room with shower bathroom on the first floor. For the "young generation" on the first floor, 1 master bedroom with bathroom and dressing room, as well as 2 children's rooms with 1 shower bathroom

By drawing this, young, dynamic sports students with a tendency towards asceticism are meant...

What do you mean by that?

For explanation I would like to build a two-generation house, i.e. an apartment for me and my husband with bedroom and shower bathroom on the ground floor, as well as a guest room with shower bathroom on the first floor. For the "young generation" on the first floor, 1 master bedroom with bathroom and dressing room, as well as 2 children's rooms with 1 shower bathroom

Do I understand the design correctly that you (the "older generation") want separate bedrooms? With a simple bed in each room? Ok, to each their own. But are two bathrooms necessary? Everything is so tight that I don’t think living there will be enjoyable. Also, I doubt that the preferred barrier-free design can be achieved with this floor plan. Additionally, it would bother me if a children's room of another family (even if related) is located above my living room. The guest would have two bathrooms to choose from, one downstairs the guest toilet, then upstairs. Bathtubs are missing for the residents. For the young generation, I can imagine that the living room will be difficult to furnish. Ok, it has something of a row house, but the latter usually have a spatial separation of the dining area – here not. I would make the stair area more open to the living area and kitchen, so fewer walls. For the "older" generation, the arrangement of the kitchen/dining area would not bother me if "older" means about ±70 years, because at that age, one probably expends less effort on cooking.

To be honest, I don't know what to make of your floor plan. I've rarely seen one so complicated, convoluted, and (from my perspective) impractical.

What do you mean by that?

What Wanderdüne probably means is that the two bedrooms and bathrooms on the ground floor are anything but age-appropriate. With a walking aid or wheelchair, you will hardly get into the bedrooms or even into one of the bathrooms! For a healthy person without mobility restrictions, the space is already very tight.

Do you have separate bedrooms and have never seen each other naked? Or why isn’t one shared bathroom and bedroom enough here? And the walk-in closet is probably more of a joke than age-appropriate. I don't know if you'll still be able to put on your pants or shoes standing up without falling when you get older. Age-appropriate living for me means having at least 100 cm of space around the bed on all sides, a chair or armchair for dressing, and the wardrobe in the bedroom so I don't have to walk far. The bathroom should ideally have both a bathtub and a shower (at least a large shower with a seat). Also here, there should be a seating option and a support bar so that no one falls while drying off. There should also be space for a second person, because you might no longer be able to get into the bathroom by yourself when you're older.

And upstairs? There will be conflicts among the children. Or why does Child1 get a walk-in closet and a shower bathroom, and Child2 only a totally cramped children's room? Both hallways upstairs have no natural light – okay – you can live with that – but for me it's a no-go.

If you want to build a two-generation house, I would build it so that the "old" live downstairs and the "young" upstairs in your place. That would save you a lot of money (bathrooms and stairs) and would definitely be more age-appropriate. So everything back to square one and start again.....

The insufficiently age-appropriate design has already been explained, but I cannot understand how the person who received the requirement developed this draft.

First: a proper multi-generational house should enable more interactions between generations than the draft does. This only shows two semi-detached houses with staggered units and a shared entrance.

Even within the individual residential units, shortcomings are built in when considered on their own. I find the parents' bedroom for the younger ones particularly bad. It is a small walkthrough room; the sleeping person is always disturbed by those who want to change clothes or use the bathroom.

You should furnish every room; then the problems will become clear.
