ᐅ How steep is the access driveway to the carport?

Hello,

our plot has a slight slope (2m (6.6 ft) over 35m (115 ft) length, but not evenly sloping) and we are currently considering how to arrange the different elements (house, storage/pantry room, carport) in terms of height differences. I would appreciate opinions or experiences regarding the slope of the driveway under the carport. We plan to place the carport 3m (10 ft) from the boundary line (more distance is theoretically possible but would interfere with other plans, so it should stay around 3m or less). Now the question is: what height difference can be managed over these 3m (10 ft) without making the driveway too steep? (The carport would be higher than street level).

Does the zoning plan allow this? Usually a minimum distance of 5 m (16 feet) from the street is required.

Yes, our zoning plan allows almost everything... except for specifications on the number of floors, and basically only floor area ratio and site coverage ratio are stated, almost nothing else is included.

A zoning plan is not everything. In your municipality, there is likely also a parking space regulation. These usually require two spaces for a single-family house. If the second space is located in front of the garage or carport, typically 5m (16 feet) must be allocated for it.

However, your planner should know this.

It doesn’t really matter, since we plan to have two parking spaces under the carport anyway, and possibly an additional one next to it... but two are planned regardless.

Our architect strongly advised us not to exceed a 12% slope, as 15% can already be quite challenging for some cars.

It’s not the slope itself that causes issues, but the transition from the road to the slope. Is there a sharp “kink” going directly from 0% to 15% incline, or are there several rows of paving stones gradually increasing the slope? There is a lot of potential to make the embankment easily drivable despite a steep incline.

That’s certainly true. However, with only 3m (10 feet) in length, there is hardly any leeway for when to actually start the slope... after all, it also has to flatten out again gradually.
Well, we have now decided to lower the carport compared to the house and the adjacent room and will either create a real “step” next to the room with L-shaped retaining blocks or a small embankment with the carport below.

We did something similar. Our garage is located quite a bit lower. Our L-shaped concrete blocks behind the garage are 1.30 meters (4 ft 3 in) high. From the garage, you can reach the house either via stairs or a ramp without steps. In between, we also have a slope.

Best regards
