Hello everyone,

I am planning a two-family house near Augsburg. There will be two apartments, each about 100 m² (1,076 sq ft), one above the other.
I have now received a rough plan from my draftsman. What do you think about the room layout? The plot is 600 m² (6,458 sq ft) and is longer than it is wide. The house will include a double garage and a basement. At the moment, I prefer option 1, although the missing second children’s bedroom (which could be a problem for renting) might be an issue. What do you think?
I will live in one apartment myself, and initially, my parents will live in the other. In the long term, it might be rented out.

I would appreciate any suggestions for improvement.

Regards,
Robert

Unfortunately, I can no longer find the floor plans of a multi-family building constructed in my neighborhood three years ago, which had one 3-bedroom apartment per floor with 110m2 (1,184 sq ft) plus terraces. I personally found the layouts very impractical but appropriate for the target group.

Building a rental property involves not only constructing the house but also understanding the target tenants. This varies greatly depending on the number of rooms, apartment size, local rent levels, location, and so on. A new build of 100-110m2 (1,076-1,184 sq ft) typically commands a basic rent of nearly 2,000€ (excluding utilities), which narrows down the tenant pool considerably, so their needs should be carefully analyzed.

Okay, sorry, I missed that. The construction style "rectangular, practical, efficient" is naturally cost-optimized. However, having an entrance on the north side would benefit the apartments. Where will the parents live? On the ground floor or the upper floor? Elevator necessary versus gardening in older age? An alternative could be a semi-detached house, where each unit can be tailored to the occupants' needs. Semi-detached houses don't have to be mirror images. A needs and future planning analysis would certainly be helpful. From your username, I assume you are about 40 years old. Is your family planning already complete? Are 3 rooms sufficient?

A duplex is too expensive, around 1 million, and too large. The budget is 800K without the land.
We will try placing the stairwell on the north side and see how it looks then.

It’s possible that the second apartment might be rented out in a few years, but that’s uncertain.

Okay, in that case it’s especially important to understand the specific needs of each resident. This is more of a multi-generational living arrangement, although there isn’t really a one-size-fits-all solution for that.
Many years ago, I built a two-family house with my parents, and each household had its own individually nice apartment.
Because of your different ages alone, your needs will vary greatly, along with personal preferences.
This could turn into a valuable thread for you if enough information is shared here. I already believe that it will be a very different house (fortunately for you) than what you might have initially imagined.

It doesn’t make much sense to just move things around like playing Tetris.
First and foremost, the requirements need to be clarified along with the possible options allowed by the building regulations / planning permission.

I’m not a fan of these designs either.

That’s what came to mind: outdated old floor plans from a time when living wasn’t yet considered a lifestyle.

Right now, I’m searching for an apartment for my elderly parents and I’m glad to say that nowadays, you can find really nice apartment layouts in multi-family buildings. You enter into a square hallway with enough space to move around and a coat closet niche, leading either directly to a bright, open-plan living area or at least to the living room. At the front, there’s a guest bathroom and a small extra room or utility room, and at the back of the apartment are the bedrooms with the bathroom. All this fits into 80 sqm (860 sq ft).

Without basic information and key data, there’s nothing coming out of this. This forum isn’t meant for playing The Sims.

as well as the reasonable options from the development plan related to it.
Exactly, and for that, you need a site plan, the details from the building plan, or the reference to the name of the area so you can look up the development plan online.

Currently, there is already 220 sq m (2,368 sq ft) of living space plus two staircases and a basement. In that case, 800,000 could be tight.

The apartment upstairs should definitely also get a nice balcony.
