We have a sloped plot and have planned a living basement, which will have floor-to-ceiling windows on the downhill side.
Would you recommend building a basement or a slab foundation with slope stabilization for this kind of incline?
Our current building footprint is 9.12m (30 feet) by 8.5m (28 feet).
There is a slope of about 1.8m (6 feet) over the 8.5m (28 feet) length.
I have attached the survey results (plot 1295) with the elevation profile and our thoughts on the house placement.
Basically, we would prefer to build larger on a slab foundation with a wood frame structure and avoid a concrete basement.
I’m looking forward to your ideas.
The soil report is unfortunately still in progress.
P.S.
The civil engineer would recommend a basement, but I would probably say the same in his position.

Nice floor plan, but it doesn’t fit your plot.
Where do you want the driveway?
How many rooms do you actually need?
Where should the garden access or the main garden be located?
Basement/lower ground/lower level does not mean you can easily add extra square meters cheaply.
I would plan a multipurpose room and building services in the lower ground floor with access to the main garden.
Ground floor with entrance, bedrooms, bathroom, possibly a side garden access.
Attic as expansion reserve, storage room.

Nice floor plan, but not suitable for your plot I understand your considerations to minimize earthworks.
We are planning two full-height retaining walls on the slope (shown in red in the image) and will have a garden with two levels (see orange and blue in the picture).
Our three children will have rooms in the attic, giving us peace in the basement living area. We will meet on the ground floor and can access the basement on the west side.
- 3 children’s bedrooms, each over 12m2 (130ft2)
- 1 living/dining area, 45–50m2 (480–540ft2)
- Master bedroom
- Office
- Optional guest room
- 2 bathrooms plus 1 guest toilet

Your experiences also match a rule of thumb we heard in a podcast. How was that rule of thumb formulated there?

How old are the children?
How do you plan to transport garden tools, lawn mowers, and green waste from the garden to the street?
How do you intend to connect the garden to the main living area?
I don’t see the house fitting within the budget.
Do you have any quotes for slope stabilization?
Does the zoning plan / building permit allow this?

How was the rule of thumb formulated there? It can be found on YouTube with Hausbauhelden and is called "Basement or slab foundation." After about one minute, this rule of thumb is mentioned:
45m² (485 ft²) should preferably be added as basement space as replacement area.

The other house, measuring 9.12 m * 8.5 m (30 ft * 28 ft), costs about 320,000 EUR with a finished basement from a solid construction company operating with a franchise system.

This will likely be expensive, and we cannot fully estimate the costs yet. We have not spoken to the civil engineer (excavation contractor) and will only do so once we have a clear plan (with an architect).

What I think of them – simply put: keep your distance – you have probably read that here occasionally.

Timber frame panel systems are generally not the first choice if you want or plan to build a finished basement. This applies especially if the home builder does not have an established partnership with a basement specialist. In that case, the builder tends to see the living areas in the basement as competing for the portion of the budget from which they profit (and tends to argue that the living spaces are located above the top edge of the basement floor).
