Teemoe86Hello everyone.
We have been searching for a plot of land for some time now in the district of Südliche Weinstraße. Unfortunately, we haven’t found anything yet because many privately sold plots are priced between €400 and €600 per square meter (approximately $400 to $600 per square yard), which is too expensive for just the land alone.
Now, toward the end of the year, there may be a chance to acquire a plot for €300 per square meter (approximately $300 per square yard) through a local allocation. However, these plots are expected to be quite small, about 400 square meters (approximately 4,300 square feet).
Our question is whether it is even possible to build a single-family house with a ground floor and upper floor, offering about 150 square meters (approximately 1,615 square feet) of living space, and still have enough space left for a double garage, garden shed, and garden.
Currently, we have a 120 square meter (approximately 1,290 square feet) garden with our condominium. It’s enough for a small garden shed and leaves “a little” garden space. In general, it is quite small, but that suits our needs.
For a 150 square meter (approximately 1,615 square feet) living area, you would expect a building footprint of about 90 to 100 square meters (approximately 970 to 1,075 square feet), depending on wall thickness—for example, 11 meters (about 36 feet) wide by 9 meters (about 30 feet) deep—plus 45 square meters (approximately 485 square feet) for the garage.
The garage usually must have a 5-meter (about 16 feet) setback from the street. The house must be 3 meters (about 10 feet) away from the property boundary.
If the garage is placed entirely next to the house, the plot would need to be at least 20.5 meters (about 67 feet) wide, considering 3 meters (10 feet) setback + 11 meters (36 feet) house width + 6.5 meters (21 feet) garage width.
You could save 2 meters (about 6.5 feet) if the longer side is oriented toward the garden, making it 18.5 meters (about 61 feet) wide.
The depth would be about 12 to 14 meters (approximately 39 to 46 feet), which is how far the house would extend into the plot. The garage, with 5 meters (16 feet) setback and 7.5 meters (about 25 feet) length, would occupy roughly the same depth.
Based on these calculations, would you have approximately 20.5 m x 12 m (or 18.5 m x 14 m) of space for the garden behind the house—about 140 to 150 square meters (approximately 1,500 to 1,615 square feet)?
Does this rough calculation seem realistic?
Additionally, due to (rain)water drainage problems (clay soil and insufficient space for large retention basins), it has been specified that all houses must have a flat roof, or possibly a slightly pitched roof with green roofing. I’m not sure how effective this really is, but it seems to be a mandatory requirement.
So far, I have rarely (actually never) heard anything positive about flat roofs. Even with many new builds, I mainly hear that water tends to leak or that there are long-term issues.
What are your experiences with this?
I also don’t have a clear idea of what a green roof with a slight pitch would look like. Could that be better for waterproofing?
What are the costs and maintenance efforts associated with such roofs over time?
The plot would be located in the community where we currently live and are very happy. The location would be ideal—12 minutes / 6 kilometers (3.7 miles) to work.

However, the plots are supposed to be only about 400m² (4300 sq ft) in size, so rather small. 400m² (4300 sq ft) is more than enough and in many regions of Germany, even plots this size are already unaffordable.

For us, the question is whether it is even possible to build a single-family house with a ground floor plus an upper floor, roughly 150m² (1615 sq ft) of living space, while still having enough room for a double garage, garden shed, and garden. That is completely feasible, as long as you don’t plan to roam your land like a cowboy into the sunset.

Why does there always have to be a garage? And that big? Just skip the garage and use parking spaces instead. Your car won’t be scared to stay outside overnight. Instead, consider a small garden shed for bicycles (or a bike shelter) or garden tools.

So far, even with many new builds, I have only heard that water leaks in somewhere or that there are long-term issues with it. What are your experiences? A properly constructed flat roof is just as good or bad as a traditional pitched roof. There are no real advantages or disadvantages (and it may even be cheaper to build).
Complaining about plot size is just nitpicking. With smart planning, you can have a nice and reasonably large garden. Depending on the plot location, you can even integrate the front yard area into the garden space.
I already thanked you for your reply this afternoon (or at least liked it).
Your response definitely helps us decide to buy the building plot. I really hope we get the chance. Even though I personally prefer other roof shapes aesthetically, I wouldn’t want to miss out on the location and the plot itself.
We want the garage because it keeps away martens, cats, and other animals, plus it provides additional storage space that is at least somewhat protected against theft.
The current estimate was about 1,000€/m² (93 USD/sq ft) for a garage with a hip roof. That is, of course, a lot of money for a 6 x 7.5m (20 x 25 ft) garage. Before buying the plot, I can still consider spending that money on other things.

[...] Is this rough estimate accurate?Depending on the floor area ratio, I think it’s quite possible that you’ll already start struggling with the calculations when accounting for the garage, terrace, and pathways. Personally, I’m not very fond of modest houses with oversized rooms meant for cars, but of course, you’re not building my house.https://www.instagram.com/11antgmxde/
