Hello everyone,

After searching for several years, we finally managed to secure a nice building plot! Soon we can get started. I am currently working on the floor plans so that our architect can submit the building permit / planning permission application.

I have a few questions and hope someone might have some experience to help me out

- We would like to install a small bathroom in the basement (habitable basement). Our home builder advised against it due to high additional costs caused by a lifting station and a backflow valve. For the washing machine and two sinks (kitchen area and laundry room), a small floor-level lifting unit would apparently be sufficient, but not for a toilet and shower. However, our basement specialist (whom we chose separately) believes that a small unit would also work in this case. Can anyone share some insight on this?

- Then, I need to plan an installation shaft on the ground floor, said our architect. Now I wonder, does the heating system (air heat pump with ventilation) have to be located in the basement directly under this shaft, or can it be placed somewhere else entirely?

- And one more thing, quite different Our plot is surrounded by other houses on three sides, and the street runs along the fourth side. The building envelope and the house are situated quite far (about 6-7 meters (20-23 feet)) from the street. We can easily install a 1.80 m (6 feet) high privacy fence on the three sides adjoining neighbors, as long as we keep a certain distance from the property boundary. But does anyone know how it works on the street side, well outside the building envelope? Does the building envelope have any influence on fences at all?

Kind regards

I don’t think so. Small lifting stations are designed for water, but a toilet sometimes has more than just water.

That matches my understanding as well. Small lift system for gray water costs around 200-300€ (220-330 USD), and for black water it’s about double that.

What exactly does your architect specialize in?

As the term "installation shaft" suggests, it is not meant for general ventilation or for the supply or exhaust air of a specific device. Instead, it is designed to conceal pipes and cables. Typically, nothing is located directly above or below it; it usually runs straight up through several (often all) floors.

Fences that are not located directly on or along the property boundary (???)—so they do not simultaneously serve as property enclosures?

Fences usually serve to enclose a property along the entire boundary, including areas beyond the building area (also called the building setback or construction limit). Local development plans or municipal design regulations may specify allowable materials and maximum heights.

P.S.: The person who knows all this is called an architect.

Thank you, dear all.

Regarding the bathroom: should we expect additional costs of around 2000–3000 euros?

Fence: the allowed fence height directly on the property line is 160 cm (63 inches) here. But that doesn’t help us because you can easily see over it. We want something opaque, 180–200 cm (71–79 inches) high. The city official said we would need to keep a setback from the property line equal to the difference (so 20–40 cm) for that height. This applies to the three neighboring sides. On the street side, both the city employee and the architect said the fence must be clarified in the building permit/planning permission, which will take several more months. I would like to find out in advance what options we have. Also, in case the fence doesn’t work out, since it’s outside the buildable area. What else could be used to create privacy? Possibly a garden shed or something similar? This is important for my planning. If our garden is completely visible from the street, it won’t be usable for us, and then it makes no sense to even plan a terrace.

And that’s a good thing, since anything taller would turn day into night for your neighbors during the winter months. Solid fences also cast shadows.

If word gets out that J.Lo sunbathes naked in your garden, paparazzi will show up even if the fence is 4 meters (13 feet) high. And Wilson only peeks over the fence at the Taylors.

Apparently, the city official and the architect were classmates. Fence height regulations are absolute. Besides that, good luck mowing the lawn and weeding beyond the fence, since you’re not allowed to pave that area. And yes, in most communities, garden sheds of about 3 x 6 meters (10 x 20 feet) are permitted.
