Regarding the third residential unit: I just saw it at my parents’ place, where grandpa and grandma used to live in the attic. The house has 2 residential units, each with over 100 sqm, and yet after they passed away, the apartment stood empty for 2 or 3 years. It is currently rented out again just so someone is in the house when the parents are on vacation (camping), and since it is the neighbor’s son who was known beforehand. It’s also a matter of feeling, and if I already own a house, I don’t necessarily want to have the feeling of an apartment. Money is often not the argument, and at some point, the 300€ a month (after taxes, deductions, etc.) might be worth the “extra quality of life” that no one lives on top of you, while you torture yourself for the next 25 years with the stairs and hallway situation.

Additionally, calculate what the necessities for the multi-family house really cost. Probably more storage space in the stairwell, certifications (fire protection, noise protection, for example), additional escape routes, 2-3 more parking spaces (an accessory apartment usually requires only 1 parking space), 3 separate ventilation systems, heat meters, calibrated meters (places) for water and electricity, proper apartment doors... some requirements do not even come from the KFW ;) These are all “just” small items individually, maybe a few hundred to a few thousand euros each, but the question of how much of the subsidy remains in the end is certainly valid. At least the structural conditions should be in place from the beginning and not just possible. Someone has to sign at the end that three residential units have really been created there. I don’t want to play the moral apostle, but at least the door and ventilation should belong in from the beginning, as well as the preparations for electricity and water billing.
“Just” an accessory apartment is much easier to handle, and a planned “warm rent” is easier to justify than with 3 residential units.

For a potentially effective four-figure profit through the additional funding, you have useless barriers (additional apartment doors) and a hallway that is only half good for eternity. The option of selling and buying suitably “in old age” (your parents do something similar) is perhaps a worthwhile alternative for the currently building generation, with more mental freedom for current planning.

I think your plan is cool, the house has charm, is extraordinary and offers possibilities, but I think there are still some points to clarify, as has often been discussed here, before the arrangement of the pure rooms should be finally decided. The approach with the common lounge and retreat area for all parts of the family would be something where 1+1 might possibly equal more than 2.

Thank you for the honest, though direct but still nice feedback. That way both sides feel comfortable.

In general, we don’t see an option in the upper floor like "we absolutely want to rent this to a stranger." More along the lines of "the child is old enough, would like to have their own apartment with their girlfriend" without them (constantly) having to cross our path (hallway). I see this practiced with an acquaintance in my direct circle. His parents live downstairs, he with his wife + child upstairs. And before anyone asks: Yes, it works very well.

We wouldn’t find the number of parking spaces that will be absolutely necessary for us so bad, as that would greatly relax the parking situation at the narrow turning area for guests (or later for our own children). For further details such as requirements for meters & co., we would definitely check again with our architect. Regarding the three separate ventilation systems, I see more advantages (e.g. less sound transmission) than disadvantages (additional cost). Even though it is always misunderstood: The third funding would only be the icing on the cake for us. If after calculation a few euros remain after the additional costs, we will be happy. If not, it’s not that bad.

All in all, thank you very much for your warm feedback. We gladly take it into account and will include it in our further considerations.

With proper ventilation, there is no sound transmission. Before you hear anything through the ventilation, the ceiling will probably come down. In our case, every outlet and inlet is installed with its own pipe.

What is really important is that your parents imagine their future - even if it is uncomfortable. At nullbarriere you will find floor plans. Both for bungalows and for individual rooms.

hm… rather give the architect the task: it is his job and he expects that not everything is correct. The path also leads to the goal here. It can work, but it doesn’t have to. I would first plan for you now and would concentrate on giving some of the main house’s floor area to the granny flat, then create a nice utility room, bring stairs into the interior areas, and design the ground floor and upper floor so that you as a family/couple will be happy there. Plan the granny flat in a reasonable size and rent it out if the seniors don’t want to yet. Something like that. Maybe as a hub/connection a room that can serve as an office or later as a granny flat room. My weekend is always too short as well :rolleyes::p
