ᐅ Top of Finished Floor and Street Elevation: Poor Planning?

Hello everyone,

When I look at the plans from my surveyor and my architect, I notice the following details.

The top edge of the finished floor is specified as 70.65 m (232.0 ft).
The ground level of the plot is given as 70.50 m (233.3 ft).
The road surface elevation ranges between 70.36 m (230.9 ft) and 70.59 m (231.7 ft).

If I add the curb height (8 cm (3 inches)) to this, the planned road curb edge elevation is between 70.44 m (230.1 ft) and 70.67 m (231.9 ft).

As a layperson, I would assume that both the planned top edge of the finished floor and the plot ground level should be higher than this, right?

And the building permit/planning permission has already been granted.

Best regards,
Marko

Why? What are your concerns?

My concerns? That the finished floor level will be lower than the planned curb height at many points. That’s usually not how it’s done. Typically, the finished floor level should be higher than the street level.

I also don’t want my property elevation (planned at 70.50 meters (231.6 feet)) to be significantly lower everywhere compared to the curb height.

It’s not fundamentally wrong, but it’s certainly not a must. People are also supposed to cover their mouth when they yawn, but not everyone does.

If I’m reading your site plan correctly, only the street in the curve area is above your ground level/finished floor level. The rainwater will flow into the local drains due to the existing curb. I don’t see any immediate risk of your house flooding.

I don’t see the problem. It might still be nice to have a few centimeters above street level, but that’s almost a matter of personal preference.

If I’m reading your site plan correctly, only the street in the curve area is above your terrain level/top of finished floor. The rainwater will drain into the nearby drains because of the existing curb. I don’t see a problem with your house being flooded at this point.

I don’t see the issue. It might still be nice to be a few centimeters above street level, but that’s almost a matter of personal preference.

My terrain level is specified as 70.50. This means most of the street is above the terrain level by up to -17cm (about -7 inches) relative to the edge of the street.

The top of the finished floor is planned at 70.65, and you’re right, so it is only lower than the street height at the curve, but....

... the curb height shouldn’t be overlooked either, right? Curb height = street level + 8cm (about 3 inches).

I agree with that!
We had to make compromises due to the specified maximum ridge height, which we can accept.
The house is about 5 m (16 feet) above and at most 20 cm (8 inches) below street level. The terrain will be adjusted accordingly.

20 cm (8 inches) below street level?!? Unfortunately, I can’t open the attached JPG – error.
