ᐅ Procedure for Building a New Single-Family Home on an Existing Plot of Land

I think the 3 meters (10 feet) distance to the street must probably be maintained. We personally resolved it similarly with our garage.

In my opinion, according to the Hessian building regulations, it is possible to build within the setback area. The 3 meters (10 feet) height and the 20 m² (215 sq ft) wall area limits can be met. However, 1 meter (3 feet) from the property line is definitely better to allow for foundation work.
A development plan that only specifies the building height seems somewhat questionable to me anyway.

Here is a floor plan I found online.

This works with a roof pitch of 20 degrees (20°) and almost two full stories.

Especially on a slope, I generally welcome not formulating height requirements as a seventh-degree equation. What bothers me here is choosing a rectangular reference point in connection with this. A preliminary building inquiry should be something a layperson can submit as well. In terms of administrative transparency, Germany is considered a developing country from a Scandinavian perspective :-(

You are not satisfied with the orientation of your shown design.

"Basically, the space in the southwest becomes too tight for us due to the arrangement of the garage and house. The terrace is not very wide, and the distance to the property line is too small for us.

Thank you for your comments."

They show you a solution, and then you don’t respond anymore. Well, good luck with your next planning meeting.

This also works with a basement, of course. However, how to design the ground-level exit then still needs thorough planning.

I have taken another close look at the basement situation. A ground-level exit is only possible if proper drainage can be ensured. Since the property itself is higher than the exit point, even at its lowest spot, the only option is drainage directly into the sewer.

How deep is the sewer?

With a window and a parapet height of 1 m (3.3 ft), it works quite well with some terrain grading.

If you are interested, I can gladly show this in more detail.

Good morning everyone,

thank you for the comments over the past few days, I will try to respond step by step.

In my opinion, the design with a basement is okay so far, but a usable area in front of the basement is hardly feasible. The lowest point on the plot is 496.50 m

That’s why I suggested a basement and ground floor.

I would also be interested in the reasoning for a basement instead of a cellar (UG).

Ultimately, considering our required space needs, the option with a basement fits better: hobby room/bar in the basement; laundry room with an outside entrance; storage; sauna, etc. It could certainly also be done over two floors, but that would probably increase the house’s footprint. Just adding one more room in the upper levels is not enough.

Garage on the street side at elevation 499.00 m, driveway from the northeast.

That would basically be the green option, right?

What is planned in the southeast?

There are two houses within the building area, nothing more is planned there. However, due to the steep slope of the terrain, they are built so low that they do not obstruct the view. In the attachment, you can still see the roof at the top.

If it were my plot, I would plan as follows without a basement but with a large storage room. This should be acceptable as a detached building.

I am increasingly warming up to this layout, regardless of whether the house is slightly “rotated” or not. Since there is forest about 100 m (330 feet) away to the west, the sun sets there anyway, and shading from the garage (with a flat roof) would hardly occur.

Although I already gave my comment earlier, after rereading the whole thread (because I couldn’t quite grasp the connection to the title), it surprises me that a floor plan is being discussed here. I seem to have overlooked the site plan with the height markings?!

We have a questionnaire in the appropriate subforum that answers open questions for readers here and is helpful for constructive feedback. I would have preferred to give the “house design” its own new discussion thread.

Now we are actually stuck with a “three-gable house” (it is called differently with a shed dormer, I just can’t remember) on a sloping plot with a basement, which looks like a multi-family house in the garden because of the height. This is exactly what you want to avoid if you talk about not building a basement but rather using a cellar as a living floor, so you avoid that kind of tower building, which also has to be affordable.

I think the 3-meter (10 ft) setback from the street should be kept. We personally solved the garage similarly.

@Dachshund90
If I were you, I would start a new thread for the floor plan discussion with a link to this one.

After 2 months and no site plan or questionnaire in the initial thread, important information is missing that would take readers with you to where you want them.

The site plan and contour lines can be found in post #52.

As mentioned above, there are reasons why we currently tend more towards the basement option.

Where exactly should I create a new thread? How does linking work?

I find a development plan that only regulates building height a bit questionable anyway.

Thanks for the info, we will discuss this again with the architect. It would be nice if the garage could be closer to the street.

Of course, it also works with a basement. But how to design the ground-level exit then requires thorough planning.

Sorry for the delayed response, I was unfortunately unavailable. I find your proposed solution very interesting and think we will forward the layout of garage and house you suggested to the architect.

I also want the architect to clarify the ground-level exit in more detail. I think it’s crucial how the terrain “around the basement” is designed.

I took a closer look at the basement situation. A ground-level exit is only possible if you manage the drainage. Since the lowest part of your own plot is still higher than the exit, only drainage directly to the sewer is possible.

How deep is the sewer?

With windows and a sill height of 1 m (3 ft), it works well with some terrain modeling.

If you’re interested, I can show you this.

Yes, please do show it, I would appreciate that 🙂 Why do you think the lowest part of the plot is higher than the exit?

I cannot say anything about the sewer depth right now, I need to find out.

I hope these were the most important answers for now 🙂 Thanks again for your great help and suggestions. The picture is becoming clearer step by step...
