Our slope location - ground slab vs residential basement

Basements are certainly cheaper. If there is groundwater there, I would at least execute the earth-contacting areas in concrete. Do you want to build a garage or carport, what does the development plan say about that? What is allowed according to the development plan? Roof pitches, floors, heights?

Just upload your floor plan.

you also didn’t fill up

Excavated and chiseled away, retaining walls made of concrete, insulated on both sides, backfilled behind, took something away here, piled something up there... In the end, it was over 1000 cubic meters of moved soil. Everything stayed on the property. There are people who move less soil with a basement build.

Most of those who wanted to build here without a basement would have already poured tons of concrete for retaining walls, plus much more soil to level the whole area.

Hello everyone, thank you very much for your opinions and the majority would recommend us a basement. Currently, we have the attached floor plans as favorites. In the basement, you can still imagine a bedroom, bathroom, and office.

Der Bebauungsplan:

[*]1 Geschossig
[*]können die Dachgeschosse Vollgeschosse werden
[*]Ist ein Drempel in Höhe von max. 1,00 m zulässig
[*]Satteldach oder Pultdach und die Dachneigung von max. 45" ist zulässig
[*]dürfen Untergeschosse Vollgeschosse sein, wenn OKF Erdgeschoss nicht höher als die davorliegende Straße liegt (Gemessen Mitte Haus zu Außenkante Bürgersteig /Schrammbord
[*]werden dl& Keller der Häuser bergse!t1g wasserdicht ausgebildet

Budget:

[*]Bezugsfertig möchten wir ohne Baunebenkosten und ohne Erdarbeiten ca. 350 T EUR ausgeben

Most of those who wanted to build here without a basement would have sunk tons of concrete for retaining walls, plus much more earth to make the whole thing level.

That’s also why my basement rule exists - mind you, not a folk saying from the regulars’ table, but collected experience from forty years of dealing with construction - that a basement, where it is not really avoidable, 1. as a "compensatory measure" practically causes costs equivalent to a realization and 2. this applies not only to obvious cases completely, but also proportionally to all the "shades of gray in between"; specifically, a flat rate of ten percentage points per 20 cm height difference (in the floor slab area). Until, from two meters of height difference, a not-built basement is factually on a cost par with the built basement.

# single-storey
# the attic floors can be full floors
# is a knee wall with a maximum height of 1.00 m permitted

I read that as "1+D, attic without full floor avoidance, but from the 1m line to be executed as a pitched roof."

Correct 1 + DG

That’s why my basement rule - mind you, not a farmer's rule from the regulars' table, but collected empirical data from forty years of dealing with the building topic

Thank you! Your experiences also align with a rule of thumb we heard in a podcast. If an additional 45m2 of room program is needed, then these rooms should be moved to the living basement for cost optimization, instead of enlarging the house.
