I have a general question in the hope that you either completely dismantle the idea or that it might be workable. It’s more of a rough idea than a concrete plan:
We (a couple planning to have children but currently without any) would like to build a single-family house on a relatively large plot of land (1000sqm (10,764 sq ft)). Since we plan to have two children in the future, we would like to design two children's bedrooms accordingly. A home office and possibly a guest room would also be nice to have. A friend who is an architect suggested incorporating a separate apartment within the single-family house.
So we came up with the idea to possibly plan the house with the master bedroom, bathroom, home office, and guest room on the first floor, and to place a separate apartment in the basement with two rooms, a small kitchen, and a bathroom, which could also be rented out. If there is a later need for two children's bedrooms, the separate apartment could be used as the home office and guest room, and the freed-up rooms on the first floor could be used as children’s bedrooms. In the more distant future, the separate apartment could potentially be used again as a separate living unit for teenage/adult children or as an accessible living space for aging occupants.
This way, there would be no unused rooms in the new build, no risk of the house being too small in the long term, and as a side benefit, there might be additional subsidies and, of course, rental income.
Completely crazy idea or possibly reasonable?

... so the same old wine with a new thread title.I wasn’t aware that multiple questions couldn’t be asked simultaneously in this forum 😉
The topic of this thread is completely different and focused on a specific question. We have already taken note of the (sometimes constructive) criticism and are currently revising our plans a bit (which is why this question was posted here).
But thanks for your (unfortunately somewhat polemical) remark... 🙄

That's how it is. So: If the goal is to do something nice for your children or, for that matter, your own parents, then go for it. But the idea of partly financing your own construction through that should better be dismissed right away.I think that’s a good summary of the various posts, thanks!

But do the costs really outweigh rental income and additional subsidies?No. marvel-online schrieb:
I’m confused. The only "luxury" would be an extra small kitchen.A separate dwelling unit that is also meant to be subsidized requires an appropriate bathroom, kitchen, bedroom, living room, hallway, a storage room with a washing machine connection, a separate water meter, a small outdoor area, an additional staircase, a second entrance, and a parking space. Plus some nice extras to make up for the downside that the landlord lives next door. If the target group is a couple, then provide two parking spaces. If you live out in the sticks, you won’t attract any students.

also as a barrier-free home for seniors.If the secondary apartment should also be barrier-free, then plan for 30% more floor space for the unit, as accessibility is expensive and requires extra space. It must also accommodate wheelchairs and care needs. marvel-online schrieb:
but possibly rent it out profitably in the meantime.What do you mean by "in the meantime"? Are you saying you can just terminate the lease easily if your family planning works out? marvel-online schrieb:
But as mentioned, it’s about the basement apartment.And it’s also a basement apartment... no one willingly moves into a basement unless they want to avoid people, are obsessed with darkness, and listen to strange music 😉 All in all, you intend to move into this basement unit yourselves, which will apparently be built just to suit one tenant?!
I wonder where you plan to put your fitness palace then 😳

pagoni202029 Aug 2021 21:39If you have attractive living space and enjoy international contacts, and someone (YOU) who consistently takes care of preparing the apartment, I would recommend using it as a holiday rental. However, you have to want to do this AND be able to, because it’s not possible to just casually earn some extra money on the side.
If you make it stylish, you can earn good money from renting it out as a holiday rental. If you don’t (for example, a shady basement apartment), you won’t get anything decent in return—it’s as simple as that.

A traditional granny flat cannot simply be connected to the main residence and used by a baby or toddler. At least not with the comfort and practicality of a family home.
First, you invest money in two separate living units, then you invest money again to somehow turn those two into one.

It's not that I just want to do it "for the sake of it." But I feel like my description of the planning hasn’t been fully understood, and no new arguments against it have really been presented yet.
Planning is definitely more challenging. But as I said, we’re talking about the basement level. So, creating a separate unit and planning it isn’t more complicated than without a granny flat.
I understand that adding a kitchen and bathroom increases the cost. But do these expenses really outweigh the potential rental income and additional subsidies? I would move the granny flat to the attic. A 2-3 room layout with hallway, kitchen, and bathroom.
Think about having a luxury master area with shower and walk-in closet on the ground floor.
You have a large plot. So, you could build about 150m2 (1,615 sq ft) on the ground floor, and depending on the building plan and house design, 110–150m2 (1,184–1,615 sq ft) on the upper floor.
Never mind. I just read the thread with the sloped site.
The question is, what is the main focus?
Efficiency (financial) or luxury?
A third living unit for employees is also a great idea!
