Spatz5Hello everyone,
We are currently facing the question of how to position all the structures on our property. Unfortunately, our plot is not flat, so I am attaching the plan showing the different elevation levels.
Basic information:
The plot is 600 sqm (6,458 sq ft), approximately 27.5 meters (90 ft) long and 22.5 meters (74 ft) wide.
We plan to build a prefab house with 1.5 stories (including a basement). We currently have an offer for a house measuring about 9.84 m by 9.14 m (32.3 ft by 30 ft).
There is no building permit/planning permission in place.
I had originally imagined placing the house roughly in the center, with the front door on the east side. Right next to it, a carport about 3 meters (10 ft) wide, which would also serve as a canopy over the door, and a garage about 3.3 meters (11 ft) wide. Yesterday, however, the sales consultant raised concerns that this is the lowest point on the plot, requiring about two meters (6.6 ft) of ground leveling (expensive), and that the building height is limited to around three meters (10 ft) because of the proximity to the neighboring property.
Alternative suggestions were to place the carport/garage in front of the house or even on the west side. I don’t really like the idea of "blocking off" the west and south sides. Maybe I just can’t picture whether enough garden and terrace space would remain. On the other hand, my partner is quite relaxed about this and would be fine placing it on the west side since he thinks it would be cheaper due to less ground work required.
I realize that the architect will probably be able to provide much better advice, but I just can’t stop thinking about it right now.
What are your opinions? Has anyone had experience with such varying elevation levels on their plot and a good idea for this?
Does anyone know a good app for planning and testing layouts like this?
In general, I’m also interested in whether we can get reliable information or experience about additional building costs in advance, especially for earthworks?
Thanks very much in advance!

Papierturm4 Mar 2026 12:11Hmm. To put it simply, it will primarily be a matter of setting priorities here.
I would definitely not build a carport or garage on the west side. The reason is straightforward: the tail wags the dog! The car would become subordinate to the house. The west means afternoon and evening light, which is ideally where living rooms, terraces, and so on should be located. Placing a garage or carport there would severely limit that.
I assume your plot is the one on the left?
In that case, I would think quite differently and especially separate the house from the carport or garage. From what I understand, the plot slopes from southwest to northeast. Then consider where the main entrance should be. (East is not a bad option, as that automatically tends to position the main living areas toward the west). However, many more planning details would be important here, depending on the final design of the house.
And a car will be fine even if it’s not parked right next to the house under a carport or garage. A suitable porch or canopy over the entrance would likely be less expensive than trying to reshape the terrain. I see significant challenges in connecting it to the east side if you attempt that. But keeping them separate? That should be more feasible.

Yesterday, concerns came up with the sales consultant, [...] I understand that the architect could probably help us much better with this, but right now I just can’t get it out of my head. What I don’t understand is how someone can approach a sales consultant when it’s clear to them that the architect would be (in my opinion, by far) the better choice.
I would first explore how interested the neighbor (who I suspect is also the seller of the building plot) might be in raising the level along the shared garden fence—and how willing the local building authority would be to relate the height of your boundary garage/carport to this adjusted level.

We plan to build a prefabricated house with 1.5 stories (including a basement). Currently, we have an offer where the house dimensions are 9.84 m * 9.14 m. The plot is almost level from southeast to northwest, while it slopes down more than two meters from southwest to northeast. The land slopes strongly and continuously towards the rear, but is relatively moderate across its width. Therefore, the house axis should run parallel to the street, with the depth being significantly less than the width. The house’s position should depend on how the neighbor feels about the fill. This can strongly influence whether a basement is economical and whether it should be simply used or also inhabited. These are all such essential factors that it is definitely too early to already be talking to a single provider!
Choosing a construction method at this stage is also pointless without more details.
And of course, I fully agree with the previous commenter that the car should take up the remaining space after the house has been finalized.

Full sun on the terrace, garage provides a protective wall from the sun and the possibility of a covered terrace.
Living area facing south and west, informal outdoor seating area in the southeast. Paving can be adapted to the terrain; a courtyard does not have to be perfectly level everywhere.

Would you then plan the front door on the west side? That would probably be more coherent overall and also better for the walking route, right?
Our potential ground floor layout was currently designed with the kitchen/dining/living area arranged in an L-shape along the west and south sides. Of course, that would then become irrelevant, but probably manageable. I’m also not sure if I’m overthinking the cardinal directions and how much sun you get where and when.

Privacy belongs on the west side, with the entrance featuring a large glass door facing south. The courtyard connects the entrance and the garage.
