We are currently working with an architect on the preliminary design for a single-family home. The architect recommends a partial basement for cost reasons. The planned partial basement would have a floor area of approximately 57m2 (613 sq ft) and would include a utility room, laundry room, and an additional storage room that could possibly be used as an office or hobby room. In terms of size, this would be sufficient for us. A full basement would have an area of about 118m2 (1,270 sq ft). We do not want to completely forgo having a basement.
Here in the forum, I have often read that a partial basement saves little cost because expenses for foundations, etc., must be offset. According to the architect, however, these costs are minor compared to the additional expenses for excavation and removal of soil, walls/masonry, doors, electrical work, windows, light wells, finishing, and so on.
The architect estimates the cost of the partial basement at around 50,000 EUR. For a full basement, his calculation adds about 40,000 EUR more, totaling approximately 90,000 EUR, which seems quite high to me. However, this would still represent a potential cost saving in my view.
What is your opinion? Does anyone have experience with the costs of partial versus full basements?

Does anyone have experience with this alternative method of simply continuing or connecting the slab?

I’m currently unsure whether it is allowed to use the link.
If, as shown in the image below, a partial basement is constructed, are the same disadvantages still associated with it, or does the situation differ with this type of construction?

We have planned a full basement.
Excavation work costs are just under 4,000 euros.
The basement size is just under 80m² (860 sq ft). May I ask what exactly is included in the excavation work? In our case, this trade alone amounts to a hefty 20,000 euros.
Thanks and best regards
