Dear community,

We are currently in the process of planning our house. The notary appointment for the plot is on October 7th, and after that, we want to decide as quickly as possible between one of the three potential builders. The plot is located in 95326 Kulmbach, and we aim to move in by May 2024 at the latest to enroll our son directly in the appropriate school.

Based on existing floor plans and various iterations and feedback rounds, we have developed this floor plan. Since we lack experience and the construction companies no longer provide useful suggestions for improvement, I hope for the collective feedback from this forum.

This is my first time collecting feedback – please be understanding if I have overlooked anything.

From my own experience, your budget won’t be sufficient for the exterior landscaping. At least not if you plan to work with retaining walls and not just a sloped terrain. I would estimate around 70,000–100,000 euros for landscaping plus additional construction-related costs and garage/carport. Get a quote from the shell builder, civil engineer, or landscaping contractor for the retaining walls including terrain grading. These costs are substantial and are often underestimated by almost everyone.

Text deleted, I am with Katja.

Whether you add a lot of money or build a balcony, it does not change the poor and artificial garden access.

If I look at the cost estimate for our outdoor area, what we have paid so far or the hours worked, what friends have paid, and the surprises a slope can present, your solution costs 100,000 (including earthworks and retaining walls).

The soil (which type is it anyway? Probably not good topsoil) will be used for the garden and perhaps up to 90 cm (35 inches) in height.

I wouldn’t pay for such an expensive basement and the huge costs for site adjustments either, but rather build with the slope. Just two stories, using the lower level as the living floor.

Of course, the construction companies offer planning services. After we brought in the floor plan, they initially had a few minor comments that we then incorporated. Afterwards, they mostly just accepted what we proposed and did not provide any useful suggestions.

This is exactly the mistake. Never present a floor plan upfront; instead, clearly state your detailed requirements and let the planner be creative.

The initial proposal with the retaining walls comes from one of the three construction companies. Do you have a suggestion on how to incorporate the site into the planning?
A skilled planner or architect will advise you on that.

I agree with the others. This way, you’ll easily spend over 100,000 without added value for walls and adjusting the building to the plot. You need to do it the other way around. Adapt the building to the plot. That’s why your living rooms with large windows should be located in the basement level facing the garden, and on the ground floor (street side), the bedrooms. Take a look at the thread by kati1337 titled “Hill house in the Südwestpfalz.” It will give you a good idea of how to build nicely on a slope. This way, you save money and avoid sinking a six-figure amount into landscaping.
