Hello everyone,

We are currently in the process of purchasing a plot of land and have already had initial discussions with our potential builder. They mentioned that building without a basement on our plot would be more complex due to the slope (we actually do not want a basement).

The situation is that at the front over about 21.5 meters (70.5 feet), there is a height difference of 2 meters (6.6 feet), and at the back over 26 meters (85 feet), there is a height difference of approximately 1.3 meters (4.3 feet).

How do you assess this? I have attached a sketch for better visualization. The house is planned to be placed on the front left side, with the garage/carport right beside it, so that the garden extends at the back.

Best regards

Yes, that is definitely not easy! We have a similar plot, and everyone here built with a basement; otherwise, I would have built without one too.

But now I am very glad, as the living spaces are bright and you can use the space wonderfully.

It is not possible to make a general statement about this.
However, the lower floor then extends sufficiently above ground level to provide the "basement" with several nice windows.
This way, you can develop the lower floor into a fully usable living area and have a house without a basement.

North is at the top, so the garden will face north.

You can’t really generalize about that.

So you can develop the lower level as a full living floor and effectively have a house without a traditional basement.

Basically completely correct and good advice, but it’s a matter of cost, since we hadn’t budgeted for a basement at all so far.

If it really can’t be done without a basement, then it will more likely be a “utility basement” without underfloor heating, standard 2.20 m (7 ft 3 in) ceiling height, and probably as much work as possible done by ourselves (standard tiles, painting walls)... just basic.
