Low ridge height results in a low knee wall

The planners just don’t want a (sub)urban villa in this development area. Normally, you look at the development plan beforehand to see if you can live with it. The development plan is available for inspection in the administration for 1 month before it is adopted. You can already see where things are headed, but you can also raise objections.

When I first read: 7.20 height, I didn’t think much of it except 2* 2.80 is enough for 2 floors, > 500 sqm, that fits. Meanwhile, I have at least learned which data matters...

The development plan is almost 20 years old.....

Otherwise, off to search for your dream plot!

Good clue. Let’s see if.... I’m considering a new approach, since I’m actually completely flexible location-wise.

And that, when you just calculated for us that at least 60m² of "real" living space plus possible dormers are available upstairs?

What do you actually want? You haven't even given the forum, the city officials, and the house providers a chance to show you possibilities.

This is more or less how we live today: I would describe it as 1.5 stories. That would be okay.

Still, I expect a first reaction from the second provider after the holidays as well.

The development plan is ancient

The development plan is almost 20 years old....

This shows how differently time spans are assessed. A development plan that is 20 years old is relatively recent to me. Very old are flight line plans from 1889, which are still legally valid in many cities today.

That would be okay.

Now we still don't know your wishes nor the stipulations of the development plan: Nevertheless, here is my summary of the previous information: In the area of the dormers (what size would be allowed according to the development plan?) there would be more space than currently. Even in the area of the roof slopes up to the relevant 1.50 meter living space line, there are no losses. Added to this is the wider ground floor. Of course, you can now, following your divide-and-conquer tactic, quote a few details from the development plan again that make the above impossible or unbearable. But then you should indeed release the plots again, because there are always endless arguments against a construction.

"Dear house prospect, please note that this house will most likely not be able to be built on a plot as typically designated by most municipalities."

I do not see this overreaction shared by the reality of building areas. The vacuum cleaner knee wall almost exclusively appears to me here in the forum only in Franconia and Rhineland-Palatinate. What you have to pay attention to in your desired profile in the development plan, even if a pitched roof is specified, is the permissibility of a second full storey.

What do you actually want? You haven’t really given the forum, the city authorities, or the house providers a chance to show you options.

Yes exactly: that’s what I already said, fill out the questionnaire and something will come from the community. Knee wall instead of knee wall for example I had already suggested.

You can find the core question of this forum at the top of the floor plan section as a questionnaire. Copy it into your house planning thread, there into the start post, and put a link to it here. With the completed questionnaire, you help the community to advise you.

Sorry if I cause confusion. Here, terms are coming at me that I have never heard of and cannot place.... etc. I understand that building is not possible in a legal vacuum.... etc. etc.

I have been a tenant all my life. Personally, I am breaking even.

That’s why I wanted to approach a former good acquaintance who once built himself with a lot of his own effort/ideas and therefore has a wealth of experience. Unfortunately, he does not have the time to accompany me as my building supervisor. I know I am fumbling around here in the forum, and I am honestly grateful to be noticed.
btw .... as an ex-employee, I allow myself to take jabs at authorities.... How I will address them after their well-deserved holidays, I already have a plan....
For the time being, I am maintaining criticism of the prefabricated house manufacturer. After showing the development plan to the salespeople, they casually gave me the impression: it will work, it fits, we can manage that.

Let’s stick to the facts: Not a single one of the 25 single-family houses in Frechen (without two stories) can be built on the designated building plots at all. The central and only limiting factor is the 7.20m. Exactly that is shown in the picture from Esroda.
Yet in Frechen, at least two of them are built exactly the way I would like them. What does that mean? These are characterful houses I would rent just as they are. As a tenant, you make 100 compromises; only the overall package has to be right.

For example, here where we have lived for 17 years: huge living and usable space, a finished 80 sqm basement apartment, 3 garages/sheds, a large meadow which we may use for playing football, but which is not in the rental contract, barbecue area, no disturbances, no barking neighbor dogs, instead swallows in the garage, hedgehogs in the grass, fireplace, doors and staircase made of oak, brick house, the outside staircase reportedly cost 25k DM, etc. etc. ... all for an easily affordable rent. The owners of the house are not in it for the money but for decent tenants.

In short: my risk of worsening myself in the sum of the components, that is, with regard to the sum of all residential amenities in their overall view, is high. There are posts here in the forum where people say: "Oh, I wish I had stayed in my old house"... If I had to put it that way.... arghhh.

Now to the questionnaire. I would gladly fill it out, but I cannot find it. Thanks for your patience so far.

Now to the questionnaire. I would gladly fill it out, but I can’t find it.

It is actually unmistakably there:

Terms are flooding over me here that I’ve never heard of and can’t classify....

Tell me ...

After showing the seller the development plan, they casually gave me the impression: it’ll work, it fits, we can do it.

Commissions can corrupt morals :-(

Not a single one of the 25 detached houses in Frechen (without two stories) can actually be built on the designated building plots.

It may happen to be the case in your building area. But no one equips an entire prefabricated house exhibition only with examples that wouldn’t be feasible in the region.

The owners of the house are not interested in money, but in decent tenants. In short: my risk of deteriorating considering the sum of the components, that is, the total of all residential conveniences viewed as a whole, is great. There are posts in this forum where people say: "Oh, I wish I had stayed in my old house"... If I had to put it that way ... arghhh.

The way you describe it, you should actually be advised to stay. However: if your nice landlords inherit or sell, you might already feel too old to make the jump (?)
