Uneconomic development plan

Hello,
is there such a thing as an uneconomical development plan?

For example
eaves heights that waste living space (small knee wall in the attic),
building lines that require a certain unfavorable floor plan,
tree locations that relocate parking spaces unfavorably to other places on the property,
surface sealing with pavements that require increased maintenance costs,
roof pitches that create a huge volume in the attic or larger roof surfaces,
plinth designs that make the knee wall unfavorably small (see above)....

Is there room for negotiation here? Or are the authorities stubborn and everything must be according to the plan?

Hello Tichu,

if you want to deviate significantly from the development plan, this involves a lot of effort and usually also increased costs. The development plans are designed so that a certain degree of building use is possible - and more basically not.

Do you have a specific BV or a particular problem? That sounds more like a fundamental question and in my opinion is very difficult to answer in general.

Most development plans probably do not have the background of annoying prospective builders, or do you think there are people in planning who simply operate under the motto... come on, let's make a knee wall of 39cm, then the upper floor is uninhabitable and we annoy the builders with that... planning? Hardly. The background is probably something else... not too large houses, not built up too much, blending into the landscape or so on...

Yep, for us the roof areas are oriented east-west! Great for the solar or photovoltaic system ;)

: usually, laypeople don't recognize the potential contained in a development plan... "we" laypeople only know a fraction of what's possible ;)

I'll answer your other question tomorrow...

We are currently also working on the development plan and the eaves heights on the left side of the street. According to the architect, 3 and 6 meters are too little for a residential basement. Furthermore, without a residential basement, there is hardly any knee wall possible on the upper floor... She is talking to the building authority this week; it remains to be seen if anything improves. However, if everything stays the same, we will probably decide against the plot. The plot is currently reserved on the left side of the street and roughly in the middle where the slope is relatively flat.

We bought a plot of land and the zoning plan includes the above-mentioned conditions. In my opinion, the creator probably didn't care much about the additional costs for the builder 20 years ago.

Most zoning plans probably don't have the intention to annoy prospective builders, or do you think there are people in planning who just randomly think... come on, let's make a knee wall of 39 cm, then the upper floor is uninhabitable and we annoy the builders with that... plan?

I didn't claim that either. I still think a zoning plan should also consider the "buildability" and that is what I find missing here.

I didn't notice that at first either... but every architect is initially surprised and cannot understand how such a plan can be approved at all. And the more I deal with it, the more I realize what additional costs arise.
