ᐅ Level the basement or the plot of land?

Hello everyone,

Our plot slopes down from street level by almost 1.80m (6 feet). Please see the image below (each square corresponds to 1 meter (3 feet)).

Now to my question: Could you share your opinions on whether you would prefer a basement or to raise the ground level? Since we want to position the house as close to the street as possible, it’s not clear if opting for a basement is the best solution here. The plot is somewhat “in between” in this regard.

Thank you in advance.

Not nothing, since nothing has been backfilled yet.
Isn't your house already built? If I recall correctly, I've seen some pictures. What type of foundation is it standing on?

The ground around the house hasn’t been backfilled yet – the house is built on strip footings that are about 2.50 meters (8 feet) high in total. The cost was around 15,000.

Backfilling will take place next year if I can get good fill material somewhere. Either through a landscaping contractor or by using a Bobcat myself.

I had proposed this solution to my architect, but he said it would be much too expensive and complicated. He wants to fill and compact everything under the house with gravel and crushed stone, budgeting nearly €30,000 for it. This also includes the garage, driveway, and terrace. What do you think about that?

I would need to check what we paid two years ago.
Filling and compacting the old basement and slurry pit, as well as the driveway.
It was a few cubic meters.

One cubic meter should weigh roughly 1.6 tons, plus losses due to compaction.

235 tons of crushed stone 0/32
Delivery, distribution, and compaction including machine hours: 7,050 EUR completed in 2017

If you build with a basement, you will have an endless amount of excavation.

Excavating soil classes 3-5 (no contaminants) and storing it on the side costs 23 euros per cubic meter (about 0.9 cubic yards).

Then you have to get rid of the material. You probably won’t need that much.

Disposal fees?
Transport costs?

At the moment, we receive excavation material delivered to us. In other words, those who have the excavation pay for the transport. I used about 120 cubic meters (about 157 cubic yards) of excavation and topsoil for my outdoor area. Cost: zero euros.

This probably varies a lot depending on the region and also from provider to provider. If I were you, I would get a few quotes myself.

My experience with architects so far: they are artists – but they have zero understanding of numbers. Either their estimates are way too high or disastrously too low.
