ᐅ Basement versus Increased Living Space on the Ground Floor

Dear all,
We are planning to build a bungalow with 3 rooms and about 85 sqm (915 sq ft) of living space. Since the plot is on a slope, we need to build with a partial basement.
Which option would likely be more cost-effective:
1. Living area on the ground floor (including a guest room) of 85 sqm (915 sq ft) and a 50 sqm (538 sq ft) basement used mainly as a utility cellar with a technical room (then we would only need one bathroom).
2. Ground floor only 75 sqm (808 sq ft), guest room in the partially finished 50 sqm (538 sq ft) basement as living space (which would require a second bathroom but could be fitted out later by ourselves).
As soon as the basement is meant to have living space, the access routes must be heated and insulated. Also, an internal staircase is necessary. A purely utility basement could possibly be accessed only from outside without an internal staircase, saving space.
Theoretically, a room on the ground floor requires about 12 sqm (129 sq ft). If this room is located in the basement, additional space for stairs on both floors and another hallway is needed, approximately 24 sqm (258 sq ft).
Am I thinking about this correctly?
Has anyone calculated a similar case before?

I have marked the dimensions on the development plan. Your error exceeds 3 meters (10 feet) from the specified measurements. The location of the plot should be definable, for example, there is a bend in the building boundary.
The thin blue line represents your plot according to the survey plan. Unfortunately, it cannot be determined if the position in the east/west direction is accurate.

I was also thinking: bungalow with a basement underneath. But I would like to hear experiences about what is more cost-effective: a partial/living basement or a purely utility basement with a larger house footprint. As mentioned, in this specific case a partial basement does not make economic sense. So a full basement with a connection room built into the slope and storage rooms for you, possibly also a guest room and a utility room; the excess basement space on the valley side would be a living basement by location—suitable for a granny flat. So pick a catalog bungalow that would meet your needs on a slab foundation except for the storage room and put a utility and living basement underneath. The option of “only utility basement, but smaller” is not feasible here—that’s determined by the slope. You basically have to build a full basement and can choose to use the unnecessary space as a granny flat (additional effort: living basement standards for these rooms, parking space for the second dwelling) or leave it as utility basement space. Of course, instead of a granny flat, you can also rent out storage rooms, which do not require a parking space.

The thin blue line shows your plot according to the survey plan. Unfortunately, it is not possible to confirm whether the position is correct in the east/west direction. The plot is exactly oriented to the north. The property boundary is the green line, the building boundary is the blue line. The plot has no bend, and the house can be freely placed within the 3-meter (10 feet) setback limits. The sewer manhole is located in the northeast corner (at the very bottom). (Plot 5)

As mentioned, in this specific case a partial basement is not economically sensible. So, a full basement with a utility room built into the hillside and storage rooms for you, possibly also a guest room and a laundry room; the surplus basement area on the valley side would be situated like a living basement—suitable for a secondary apartment. So, choose a catalog bungalow that would meet your needs “on a slab” except for the storage room, and add a usable and living basement underneath. The option of “only a utility basement, but smaller” is not an option here—the slope determines that. You basically need to build a full basement and you can decide whether to use the extra space as a secondary apartment (additional effort: finishing the rooms to living quality and providing a parking space for the second unit) or just keep it as a utility basement. Of course, instead of a secondary apartment, you can also rent out storage rooms, which then do not require a parking space.Why does a partial basement not make sense? Does it really save nothing?HalloClarissa20 Apr 2022 19:5511ant schrieb:

Why not do it like this from the start?
Now I have roughly positioned the plot correctly.
There is an elevation difference of about 5.7 m (19 feet) on the east boundary and about 5 m (17 feet) on the west boundary. The street also has a slope of approximately 4%.
Where should the garage or parking space go?
