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

Whoever can make sense of these confusing thoughts, please translate them for me, an old man. Thanks in advance.

The main question is whether extending the garage by 50cm (20 inches) is sufficient to fit two cars inside the garage and to build an additional carport on the right side of the garage according to the plan. Is that clearer? Please feel free to explain what is unclear 🙂

You probably mean widening instead... since you want to increase the 5.34 m (17.5 feet) space to the right of the stairs by moving the right wall 50 cm (20 inches) to the right.

This means the carport will only be 3 m (10 feet) wide, or if you place the posts on the property boundary, the front section would be 3.3 m (11 feet).
Is the carport attachment on the garage side planned directly on the wall without posts?

Also, you need to be aware that in the carport you will always need to park as far right as possible so the driver can still exit on the left side. This means passengers on the front passenger side should exit in front of the carport.

I also find 5.34 m (17.5 feet) of usable width for two cars in the garage rather tight, unless very small cars are used.

The carport would then only be 3 m (10 feet) wide, or, if you place the posts directly on the boundary, the front area would be 3.3 m (11 feet). Is the carport attachment on the garage side planned to be fixed directly to the wall without posts? Also, you have to be aware that in the carport you will always have to park as far right as possible so that the driver can still exit on the left side. This means passengers on the front passenger side should get out in front of the carport. I also find 534 cm (17.5 feet) of usable width for two cars in the garage to be relatively uncomfortable, unless you have very small cars.

What would be a comfortable size for the interior garage? If necessary, the car could then be parked lengthwise along the house instead of in the carport.

Something was simply misplanned here, and now I’m trying to salvage the situation after the fact.

Hello,

according to the Bavarian parking space regulations, parking spots must be at least 2.30 m (7.5 ft) wide. Usually, most parking spaces at hardware stores, supermarkets, etc., are planned to be 2.50 m (8.2 ft) wide. In your design, they will be about 2.70 m (8.9 ft) wide. A modern mid-size station wagon has a body width of approximately 1.85 m (6.1 ft) without mirrors. If both doors need to be opened comfortably, you can easily add 75 cm (29.5 inches) per door. So, in this example, the space required per car is already about 3.35 m (11 ft). Adding 50 cm (19.7 inches) between the opened doors of adjacent vehicles and 25 cm (9.8 inches) to the wall results in a total width of 6.80 m (22.3 ft) needed to comfortably walk around the car with the doors open.

Just as an example—this is rarely the case in reality. I would recommend allowing for the 50 cm (19.7 inches) extension for the garage.
