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

A width of 3m (10 feet) is usually sufficient for a parking space.
Whether or not it is easily accessible is not directly affected by widening it—unless you have to make a very tight turn to get there, which can of course be challenging.
For just a carport, 3m (10 feet) is fine.

For cars inside the garage, widening it obviously helps. We have an internal width of 6.80m (22 feet 4 inches), and that is very comfortable, especially if you want to move bicycles through the back.

My recommendation: go for it!

I don’t feel confident doing an independent design, so the garage planning was naturally done by a construction company. However, I don’t fully understand what kind of plan is needed in order for you to provide a meaningful response. The basement is set 30cm (12 inches) lower than the main house, since the building 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.

The quality and depth of advice possible are on a completely different level when the questioners provide a comprehensive overview; quick snapshot snippets offer little basis and have limited “grip.”

Basically, I’m mainly interested in experience-based input regarding a sufficiently wide garage. A width of 6.30m (20.7 feet) is the maximum I can accommodate, which should be enough for two cars.

I have comfortably parked and accessed both a Ferrari 355 and an SL R230 as well as a W124 in single garages of 2.9 m (9.5 feet) width, but the driveway was straight. For double garages with a similarly straight driveway, I would find 5.5 m (18 feet) wide also perfectly adequate. However, I usually park in pairs “69 style,” meaning both cars have their passenger sides facing outward.

Note: When considering the required width, the vehicle width is only one factor; the position and length of the vehicle door are another. I have, among others, a Smart Roadster, a really small car. The doors are long, the footwell is deep, and the seating position is low – I need a lot of space for the door to open enough for me to get out. In any case, the 5-series estate requires less space to open the door than the small Roadster.

The 5-series station wagon definitely needs less space to open the door than the smaller Roadie.
That’s why I mentioned two long-door models as satisfied users of the garage. The A124 also requires more exit space than the W124.
