Floor plan single-family house with separate apartment as a 3-unit house

120 cm is not a kitchen island, at best it's a sandbank. :)

Are you by any chance related to @Felix85? :p

At least not that I know of ;)

I think the plan is good – the architect really paid off. But the construction itself is really unfamiliar to me. I assume the parents are rather young? And the move-in is planned around 60? The granny flat, as it is currently laid out, is in no way accessible for disabled people. I always have a hard time with these “jack of all trades” houses. If the ideal case doesn’t happen, then you three end up on 230 sqm with a ton of rooms. And I have seen a lot of such single-family houses where during the planning phase they thought about renting out later – no one does that. Because in a single-family house you don’t want strangers so close. It’s like a shared flat.

Thanks, we agree too. It’s always nice to hear some positive feedback! :) I didn’t answer all your questions in the first reply, I quickly added that as an edit earlier. That answers most of your questions.

The granny flat is not intended to be accessible for disabled people. “Age-appropriate” fits better. And for this purpose, we think it is. Don’t you? Then we’d be happy to hear feedback about what would “bother” you! The parents’ move-in is planned approximately at retirement. One has to say that my father is a self-employed farmer and the farm is tied to the current house. So earlier wouldn’t be possible anyway. And the granny flat shouldn’t stay empty for that long, so we would use it as an office in the meantime.

I already wrote that renting out would only be the last option. So it’s rather unlikely. Exactly for the reason you mentioned: We are building because we want something of our own and not “strangers” just one room away.

What I was still thinking: What is currently “sleeping” on the ground floor is actually intended as our office. But since we want to use the granny flat as an office first, this room would in fact be empty at first. Maybe it would make sense to leave out the wall to the living area (to the west) for now. That would create a large living area. After 5-10 years, a drywall could be added as a divider. And in the meantime, we wouldn’t have an unused room “standing around.”

My parents would be grateful if cooking, eating, and living had to take place in one room of 25 sqm, while I celebrate the same on over 70 sqm. :) For age-appropriate living, the bedroom is too small for a couple. It would work with a single bed for one person. Bathtubs are no longer planned these days in senior-friendly areas. Instead, larger showers with seating are used. Search for "barrier-free building - floor plans for life" - there are sample floor plans. Or should the parents move out again immediately if they have mobility issues or need care?

The property looks good, southwest garden, access from the northeast appeals to me. The rest not so much o_O

The kitchen looks impractical to me, technology too small for a multi-family house, hallway without windows upstairs with a door to the staircase.

It seems to me again that instead of building a really nice residential unit, there is a desperate attempt to fit 3 units in although actually only one is needed right now. Are you related to by any chance? :p

I already wrote: We are also not 100% happy with the kitchen yet. We gladly accept all improvement suggestions from all sides - so bring them on :)

The technical room is, after consultation with the architect, large enough for the technology. He favors a compact air-water heat pump with integrated ventilation and hot water storage. The original size is already marked on the plan. Then the house connection, a control cabinet and a water softening system will be added - that would fill the room. Doesn't fit?

We really like criticism when it is justified. We are neither trying to force anything desperately here, nor do we want to regret later that we cannot divide the house into 2 units due to, for example, a staircase placed in the middle of the living room. Children grow up too. And the fact that they don't necessarily have to move out of the house to have their own apartment is something — as we think — positive. TLDR: Criticism? Gladly! But then please with justification and/or improvement suggestions.

My parents would thank you if they had to do cooking, eating, and living in one room of 25 sqm, while I celebrate the same on over 70 sqm. :)

People are so different :) My parents think the size is absolutely sufficient for their age. Reduced to the essentials, but still not too cramped so that you feel uncomfortable.

We gladly take the other tips regarding the granny flat and will see how we can fit them in. I already have one or two ideas. By removing the bathtub, the bathroom could be made smaller and the bedroom a bit larger. But first, we'll look at your recommended reading. Thanks!
