Hello.
I have a plot of land with a slight slope; the height difference from the front to the back is about 1.5m (5 feet).
For cost reasons, I would prefer to forgo a basement and have as much as possible on the ground floor level. The upper floor is intended to be used either by the children or possibly rented out later, depending on what the children decide to do.
I expect that building upwards with an additional upper floor will provide more flexibility than building downwards with a basement, which is usually less pleasant to live in compared to the same area at ground level.
A large double garage will be built on the east boundary. The neighboring property on that side only has frosted bathroom windows, and the owner (a relative) has also agreed to an easement if the garage is somewhat larger.
Development Plan / Restrictions
Plot size: 814m² (8,761 sq ft)
Slope: approx. 1.5m (5 feet) across the entire area
Floor area ratio (FAR): 0.4
Plot ratio / floor space index: 0.7
Maximum number of floors: 2
Roof style: gable, 30 degrees
Ridge orientation: east to west
Maximum heights / limits: none, the development plan dates from 1980, and various roof and building shapes can be found in this area
Owner Requirements
Style, roof shape, building type: definitely no flat roof, no bay windows or dormers
Preferably solid construction (masonry)
Guest toilet on every floor
Basement still undecided, 2 floors possible
Walk-in (level-access) shower preferred, bathtub not necessary
Flexible use for one large or two small families in the future should be possible.
House Design
Based on consultation with a licensed general contractor (GC) from the region
The shell construction will be provided by the contractor, while I will do the interior finishing myself, including electrical work, plumbing, water installations, flooring, interior plastering, etc., as I am a professional. I plan to organize and subcontract the remaining work to experienced local companies.
There is no rush, so the complete interior finishing can take some time.
Preferred heating technology:
District heating connection supplied 100% with renewable energy
Why does the design look the way it does?
The design was created by the architect after consultation based on our ideas.
What do you think of the design? What would you change?
Since the terrain needs to be adjusted and the foundation slab filled to compensate for the slight slope, how much would you estimate the additional cost for a basement? The planner suggests that a basement should be considered with a height difference between 1.5m and 2m (5 to 6.5 feet).
Do you have any other thoughts? Once you commit to a design, it’s easy to become a bit blind to alternatives...
Thank you and best regards!

hanghaus202314 Sep 2023 12:39I have marked the building boundary. Unfortunately, it’s not clearly visible on your plan. Is the building boundary 16 m wide (52.5 feet)?
In my opinion, you are exceeding the northern building boundary by 2.5 m (8.2 feet).
This way you are within the building boundary.

How would you evaluate the profitability of a basement compared to grading/fill work or excavation for a basement? For a significant height difference of 1.26m (4.1 ft), the 11ant basement rule (which will be published in eight days at a well-known location) suggests that the basement replacement costs should aim for about 70% of the costs of a constructed basement, meaning an actual basement.

hanghaus202314 Sep 2023 13:11As I mentioned, I would divide it practically. If two floors are planned, I believe this way works better.
Also, preferably without a basement.

Maybe I see horses everywhere because I have one myself, but why place it so far from the road? That’s a really long driveway/paved access path, which also adds to the cost.
We have a similar slope on our site. We built one floor partially into the hillside. I’m not sure what the technical term is, but when you look at the house from the road, it looks like a bungalow. From the back, you can see both floors.
To get into the living spaces, you go down the stairs. The garden is behind the house. You can access the garden from the living room on a level floor.
I’m attaching a few pictures. We are very happy with this solution. Also, we were able to keep the excavation material on the site. Excavation removal is extremely expensive right now.
