Cost estimation for building an architect-designed house - Munich surrounding area

Even though you can’t get a 100% comparability between an architect-designed house and a prefab house, I would like to answer the question for myself: Can the prefab house provider offer me more house (including extras) for the same documented requirements than the option with solid construction + architect?

You probably still wrote while I had already sent post #23. If you follow the approach I advised there, you will get the answer that way. Otherwise: get in touch :)

Caution: Architect-designed houses and prefab houses are NOT opposites or parallel alternatives, but have a significant overlap. Especially in the house size asked about here, there are even prefab house manufacturers who specialize in pampering privately insured clients with gold-rimmed marble palaces that can "even shock " and that achieve at most two stars less than the villa of ;-)

No. Even within the scope of prefabricated house construction, an architect is needed, as you are not buying off the shelf. Only the construction method differs, nothing else.

What shocks me most is the guild of architects – but old hat, I'm just traumatized... for that, I still find butchers and meat cutters quite okay so far... I am trying to answer this from my experience shaped by suffering whether I get more value for money from the "prefab manufacturer": 1. This cannot be answered; from my experience, the prefab manufacturer was always more expensive for the same design than the turnkey general contractor from the neighboring town... 2. Planning with an architect is definitely more expensive, you pay HOAI and not a "flat" 5 thousand to the prefab manufacturer for planning services. 3. All the other service phases also cost more according to HOAI than when offered by the general contractor. 4. For that, with architect-led construction, you can compare bids from trades and choose the best = cheaper than with the general contractor. I decided in favor of planning with an architect but to save my nerves in the long run "build with a general contractor." GD

For the further course of the discussion, we can assume that the plot (approx. 1000m2) exists as a fixed component and the costs are not changeable. The building envelope has a footprint of 155m2,

I have now looked at the location in (you could have linked the two threads yourself!) and don't directly see 1000 sqm of land there: does approximately 1522/3 also belong to the plot in question besides 1522/6? – although there is a boundary line in between, it might still be worth trying a merger in order to be able to increase the site coverage ratio a bit. The building envelope would still remain "not comfortable" in size and layout; at least an extension of the main building envelope into the Ga building envelope for only the normal building setback on this side would be very helpful.

Our tradition as a butcher dynasty was already not continued by my father, and a butcher’s house... I think / have even sent more general contractors into the desert than has worn out expert assessors ;-)

Anyone who knows me can guess which song by Katja Ebstein comes to my mind in this context *LOL* *SCNR*

I have now looked at the situation in (you could have linked the two threads yourself!) and I don’t directly see 1000 sqm of land: does the parcel 1522/3 also belong to the property in question besides 1522/6? – although there would be a knödellinie in between, it might still be worth trying to merge them to slightly increase the floor area ratio. The building plot would still not be “comfortable” in size and shape; at least an extension of the main building plot into the Ga-building plot for a normal building setback on this side as well would be very helpful.

11ant, now you’ve unsettled me :) I have uploaded a somewhat larger section again. So if you ask me, nothing at all merges with the property. The area marked in yellow is 99% likely my target plot of 1060 sqm.

Can you briefly explain what you mean by “extension of the main window into the Ga-building plot also on this side”?

Since we are on the subject: horizontally next to it there is this shed built. Above it, one might possibly achieve an extended building area. What do you think?

The area marked in yellow is 99% likely my 1060m2 target plot.

Okay, it is probably larger than it "appears" at first glance, but if the recorded numbers are roughly correct, it should still be only about 780 sqm by rough estimate and without guarantee ;-) (rounded with a floor area ratio of 0.2, that would fit with about 155 sqm). If it is only about this one parcel, of course there is nothing to merge, pardon, "to unite" would be the correct term here.

Can you briefly explain to me what you mean by "extension of the main window in Ga-building window also on this side"?

To the east, you have a 4m wide distance from the building window to the border, to the west, however, with 6m, even double the usual minimum building setback. Having only 3m on both sides would allow the house to be 3m wider in total. This would allow the house to use its possible footprint even if it were set back from the street further than the current existing house does.
