Dear forum members,
We have a sloped plot with access from the top, approximately 20m (65 feet) wide and about 45m (148 feet) long. It becomes flatter at the bottom, and the slope at the top is about 15%. The slope runs from east to west, and the previous owner already excavated a terrace
across the entire width decades ago. The neighboring houses also have terraces built up to this level.
Since we are a family of four and the house also needs to include a respectable commercial space for customer visits, we will probably need at least 200 sqm (2,150 sq ft).
I’m not too keen on the idea of building a three-story tower with 70 sqm (750 sq ft) per floor there. On the other hand, given the width of the plot (we also need space for a garage and carport) and the slope, we cannot fit the rooms we need into just the basement and ground floor. If we build too far back, there will be hardly any garden left on the terrace.
Do you have any more creative ideas on how to work with the slope so that a small garden can remain? Or is the tower our only option?
Our budget is about 650,000 solely for the house. However, for some trades, we have good conditions because family businesses are involved.
Right now, I am mainly looking for some ideas before we meet with an architect. We are very open regarding the implementation.

Thanks for the planning. I generally like the idea. I’m just afraid it might not be allowed 🙁
In the plan, I found the following: "Garages are inside residential buildings, no alternative locations (also not for parking spaces)." This probably means that garages ATTACHED to the house with boundary development are not permitted, and carports are definitely excluded, right? Or is it possible to get approval for that? When the plots were first developed, the term "carport" wasn’t even in use yet.
Fill layers for garage: secured from 0.5m (1.6 ft) above wing wall
Furthermore, I found the following information in the development plan:
Floor area ratio (FAR): 0.4
Site occupancy index (ratio of built ground floor area to plot size): 0.8
Maximum number of storeys: 3
No stepping forward or back of building lines allowed (no bay windows?)
Here is the sketch:
Fill and excavation: permitted with the construction of a retaining wall from 0.5m (1.6 ft) up to 1m (3.3 ft) above ground level 
The restriction on stepping forward or back of building lines probably isn’t taken very seriously, judging by the neighbors.
If these are the contour lines, please take a photo. The area where excavation took place must be quite steep. If contour line #4 runs along the street, then the street itself has very little slope.
How did the neighbors build? Garage inside the house? It would be a good idea to consult the building authority to see how strictly the old development plan is still enforced. There might also be a local parking space regulation. Where do you plan to park the customers’ cars? Unfortunately, I’m not very familiar with Hamburg.

How have the neighbors built? Is the garage integrated into the house? You should check with the building authority to find out how strict the old zoning plan or development plan is today. There might also be parking space regulations. Where do you plan to park your customers’ cars? Unfortunately, I’m not very familiar with Hamburg.
As you can see in the photo, the first section is indeed very steep.
The northern neighbor has the garage integrated into the house, while the southern neighbor has theirs in an attached extension (forming a slight L shape). The houses date back to the 1970s.
We actually need two parking spaces for ourselves and at least the option for guests to park on the driveway.
If we put the garage inside the house, we would lose a lot of living space on the ground floor. With a partial integration, I find that the pitched roofs always look a bit odd, especially the constructions on the part that protrudes (but I’m happy to be convinced otherwise).
So far, we are considering placing the garage on the north side, as it would block a lot of light if placed on the south side.

Carports are often allowed to be built without a building permit / planning permission. Does the Hamburg building code apply in this case?
Are there no specifications regarding the number of parking spaces per residential unit / house in the development plan?We are not building in Hamburg. We would probably have fewer slope issues there 😀. Did I state that incorrectly somewhere?
The state regulation allows construction on the property boundary. The wall facing the area is allowed to cover 20sqm (215 sq ft).
The development plan only states that an attic room (up to 36sqm (387 sq ft)) or a ground floor room (up to 20sqm (215 sq ft)) are permitted. No alternatives.

I’m out.

I'm out. You can’t see more because we don’t have better photos. This is not due to any ill intent or laziness on my part. We already had to push our way through thick bushes to get this picture. Below is not a road but a densely overgrown agricultural plot. From above, the neighbor’s entire garden is visible if you photograph the edge, and I don’t want to post such a photo without their consent. When I take pictures from the center, you can only see broccoli.
The slope is visible along the path at the top right and at the neighbor’s fence.
