ᐅ Double garage for two vehicles with an attached carport

Hello everyone,
We are currently in the final stages of building our house and are facing a fundamental issue.
We are constructing a multi-family house (upper floor rented out / 100 m² (1,076 sq ft)) and will also be moving in ourselves. My wish is to have a double garage for two vehicles.
Due to the large floor area of the garage, the idea arose over time to include a basement underneath, which is why a staircase (1 m (3.3 ft) wide instead of 1.10 m (3.6 ft) as originally planned) has now been added.
However, I am now concerned that the remaining width of 5.44 m (17.9 ft) may be a bit too narrow. The mason has suggested, since the garage will be built with masonry anyway, extending the width by 50 cm (20 inches) outward toward the property boundary. This would leave a remaining width of 3.03 m (10 ft) between a potential carport next to the garage and the property boundary. The adjacent property is family-owned.
The question is whether this idea of extending the garage is feasible and compatible with the basement staircase. We would prefer not to park cars in front of the garage or only fit one car inside, as the garage is intended exclusively for our use as landlords. The second option would be to omit the basement staircase – which we would rather avoid.
We would appreciate external opinions to get a better understanding of the situation.
I look forward to hearing about your experiences.
Best regards

The basement stairs are actually intended to function as a kind of hygiene barrier, since the utility room is located to the left of the basement stairs. I don’t understand... a hygiene barrier from the basement?
What is supposed to happen in that basement area under the garage?

What would you advise me? How can anyone give advice without knowing the conditions and the plans?

The basement stairway in the garage, which is 1m (3 ft 3 in) wide, is meant here. It currently just rests in place and could be lifted out again. The opening would then need to be shuttered and supported from below in order to be able to pour concrete there if the stairs were removed. kbt09 schrieb:
So, what is supposed to be stored in this basement? It will get tight down there to get around the corner of the stairwell wall. The bicycles are planned to be placed behind the cars in the extra half meter (1 ft 8 in) of garage length, once the used, unused garage basement stairs are sold through classifieds. Only items that can be carried via the spiral staircase will go into the basement.

The basement stairs are actually also intended to serve as a sort of mudroom since the utility room is located to the left of the basement stairs. From there, you could reach the apartment via the spiral staircase. Going through the back door comes with consequences, LOL.
Drink tea, smoke tobacco. If you accidentally did it the other way around, then make sure not to plan the house yourself for 48 hours!

Carport (currently 4m (13 feet))Why does your original post say 3.53m (11.6 feet) wide?If I’m not mistaken, your basement room under the garage has an opening at the back for a light well. How do you plan to handle this if you extend the concrete slab towards the rear?
The last point is the building permit / planning permission. What does it say about enlarging the garage?

Only items that can be carried down the spiral staircase will go into the basement. From what I understand, someone has now grasped my point, which I am glad about. The extension of the garage at the rear still needs to be reviewed, since, as rightly mentioned, a light well is planned in that area.
Primarily, the focus is first on the horizontal widening of the garage while keeping the basement staircase. Of the remaining 4 meters (about 13 feet) towards the property boundary, we can use a maximum of 90 centimeters (about 35 inches) for widening, otherwise, we will encounter structural issues. This means the interior dimension of the garage from the basement staircase would be approximately 6.30 meters (about 20.7 feet), which should certainly be enough to park two cars. Whether a carport could still fit with the remaining 3 meters (about 10 feet) is doubtful. I still need a parking space (outside the garage) for the tenants.
However, I see a planning error on the part of the construction company because the door located behind the staircase landing would lead to nowhere due to the light well.

Was there even a proper plan from the construction company? To me, the drawings look more like copies of an amateur plan that a client with average spatial imagination might have created using mechanical engineering CAD software or similar. Entrusting such work to a draftsman for preparation for a building permit / planning permission would not qualify as "planning"; neither was the contractor obliged to check for such obvious mistakes, nor would such checks normally be part of the approval process. The excerpts shown here are not sufficient for a general overview in my opinion.

I don’t feel confident to create an independent design myself, so the garage was naturally planned by a construction company. However, I’m not entirely sure which plan is needed for you to provide a meaningful response. The basement is set 30cm (12 inches) lower than the main house since the house needed protection against flooding from splash water and has since been waterproofed. The basement is already built, as are the exterior walls of the garage.
Basically, I’m just looking for practical experience regarding a sufficiently wide garage. I can fit a maximum width of 6.30m (20.7 feet), which should be enough for two cars.
