Floor plan for a two-family house as a semi-detached house with 160 sqm in Bavaria

Please simply sketch the buildings roughly on the site plan, which should be dimensioned. What is supposed to be inside can then be better understood. The narrow corridor cannot be understood at all.

Here is a rough site plan with the measurements.

Thank you very much for your help.

The garage gets the best spot on the property.

A single-family house for families can also be rented out.
You are now accepting significant deficiencies and costs in the floor plan just to rent out 2 apartments later.
I would reconsider that.
You are building for yourselves now and not later for renting out.
For example, you now have 2 full bathrooms that use up more space than usual for a single-family house of this size. Space costs, bathrooms cost.
In return, there is no proper coatroom now, you have tunnels and small rooms. For the budget and size, you can build a spacious house.

Who gets the roof terrace? Why is there a 3rd bathroom there?

Garage location is ...
Living, cooking, eating doesn’t work. Far too small. Take graph paper and draw furniture to scale.
Especially, why squeeze the open-plan area into such a small space given the size?
Bathroom as a shower bathroom and coatroom inside the house.

How will you use the rooms upstairs after moving in?

Attached I have tried to answer your questions as best as possible.

Garage gets the best spot on the property.

Location of the garage is Living, cooking, eating doesn't work. Far too small.

We thought that we could make a nice roof terrace on top of the garage towards the south. Was this apparently not a good idea?

Who gets the roof terrace? Why is there a 3rd bathroom there

We planned a 3rd bathroom up there because the children want to go upstairs and have the possibility to shower or quickly use the toilet.

I have attached the plans we came up with yesterday after receiving so much input.

How do you use the rooms on the upper floor after moving in?

I wrote down the room usage in the attached plans.

Especially why squeeze the all-purpose room into such a small room given the area?

We enlarged the all-purpose room on the upper floor. We thought the size would be sufficient.

Size of the plot: 580 sqm No. 13

And why are you planning on No.12?

But even there the garden would be ruined by the garage. Who wants to sit there on a silver platter?
An outdoor area for an apartment is planned with privacy.
About a hallway that should waste as little space as possible, I won't say anything.

Uh, do you have 12 or 13 now?
The budget with the terraces and the living area won’t work.
With the attic you’re over 160 sqm anyway.
Plus the south side is occupied with cellar replacement rooms.

Delete all your thoughts and start from scratch.

What room program do you need and want now? Then plan a generously appearing house. Then you can think about a possible division.
Although single-family houses can also be rented out.

You enter the house, where do the jackets and shoes go? Into the already long and dark hallway. Yay, welcome to the far too small city apartment.
In the evening, you walk barefoot towards the bedroom, trip over the school bag, step into the puddle.

For that, you pay for a bathroom that serves no purpose other than cleaning, the great terrace on the garage is cleaned twice a year, is too warm and nobody feels comfortable there, privacy zero.
Upstairs the roof terrace is leaking, junior smokes there secretly, and the kids’ rooms are too dark because they're facing north.

Rental. Bathrooms too outdated, the ground floor apartment doesn’t want the garden, there are only two of us. The family for the upper apartment wants the garden and the bedrooms on one level.

And draw the desired and existing furniture into every floor plan to scale, with space to move.

Narrow corridor to lose as little space as possible.

Claustrophobic traumatization with every room change in exchange for more nominal room area, does that make one blissful?

I hope the link is okay?

I don't think so. Besides, the plan part is missing (?)

We thought that one could make a nice roof terrace on top of the garage in the south. Was this not a good idea?

Yes, that was not a good idea. Two roof terraces are two too many – aside from the setback distance that would have to be observed on the garage. I mark the storage room on the residential floor instead of in the upper floor with a question mark, bigger and bolder than from Würgerking. What is actually planned for the half partner, also such nonsense? – after all, they have to fill the same profile with sensible rooms...
