Bay window possible? New construction in new development area?

Previous owner of the property had been granted approval for a winter garden with a 3x3 meter balcony in his building application.

Then you too, as long as his building permit is still valid. However, this cannot be transferred to 6.0 x 2.5 meters, and certainly not to a bay window (or do you even mean a cross gable?). As I said, why don't you show the "(almost) final" plan.

Then you too, provided his building permit would still be valid. However, this cannot be transferred to 6.0 x 2.5 meters, and even less to a bay window (or do you even mean a dormer?). As I said, just show the "(almost) final" plan.

This plan is purely our idea of how we would like it. The drawing will not be correct either, as I simply drew something myself for fun with the first program I found. What is correct are the external dimensions 10x10, the orientation of the plot, the dimensions of the plot, and the correct position of the front side + garage.

I am still waiting for a correct drawing from the architect, who will also include furniture etc. and still optimize it.
Just as the correct thickness of the interior walls is missing, only the outer walls have the correct thickness.
The red beam is supposed to represent the stairs, I can’t do it any other way :(

But I think the bay window with the deviation of the building window is visible and understandable.

The previous owner had planned a two-family house, but we are building a single-family house and have therefore redesigned everything. Thus, we are submitting a completely new building application with new plans, structural engineering, etc. I just wanted to say that a rear development has already been approved in the area. However, only a conservatory including a balcony.

to plan our final and then discuss them afterwards with an .

Wrong order. You have many questions and these are questions you ask a professional, namely an architect who also creates a approval-capable drawing with a functional house design.

Better discuss the floor plans here first. If these have been created so far without an architect, finality might also be just a pipe dream,

These are quite new traits from you: constantly appealing to those who come along with self-drawn floor plans to actually go to a proper architect instead of playing planner themselves. … and now something like this.

from whom an "architect" (in quotation marks, meaning a building application draftsman of a general contractor or sales representative of a prefab house company) will not wake you, if your amateur planning is able to be approved.

… and then also – without any hint to it – the insinuation that it would be a draftsman.

Does this thus directly exclude the bay window?

No, just because something is not mentioned in the development plan does not automatically mean it is excluded. A development plan presupposes the content of the building code or state building regulations.

Otherwise a bay window should not be possible, can we build an enclosed warm conservatory?

The problem is the development plan does not formally exclude a bay window,

A bay window is technically called a projection. Projections are no longer explicitly mentioned (in NRW) as long as they do not exceed one third of the width of the facade. Also, according to the NRW building code, they may protrude a maximum of 1.6 meters from the facade.

The architect himself only suggested to include it in the plan and to submit the . But maybe someone here has more experience.

Development plans are usually clear. They are only vague for those who want it otherwise and look for loopholes. I’ll take a risk and say: if a simple conservatory up to 3 meters deep is allowed, then any other projection is also allowed. According to the NRW building code, a projection is generally permitted. The development plan is quite open on this point anyway, as long as no setback lines are triggered.

I think the bay window with the deviation of the building window is evident and understandable.

Yes, only it is not a bay window but an extension attached to a house. Since the conditions up to one third etc. are not met, I consider it not approval-capable. The architect should also know that. Furthermore: if you plan such a bulky extension, it affects the entire house design. So simply saying “let’s just include it” does not work. Because without the extension, the living room does not function.

The plan is purely our idea,

Sigh… I would see no sense in this extension as indicated. On the left side of the plan a niche for leaf catchers arises; on the right side inside the house there is an area that is initially superfluous with its 2.40 meters width. Window placements and the extension cause sunlight to be kept out of the house for half of the daytime. Well, then you can complain about usual things: stair too short, path to the kitchen too long… But before the sketch from you is discussed here: take a look here: Nice subforum, nice questionnaire – then you will reach those who know about house designs here.

This plan is purely our idea of how we would like it. It will also not be correct from the drawing perspective, since I simply sketched something myself with the first available program just for fun.

So I probably hit the mark quite well, not to take the finality level as "face value." The intention was therefore not a truly mature design, but merely an amateur sketch in the stage of "this is the best we could think of, now we show it to a professional." Any random software is more than sufficient for that – even better is good old graph paper.
For the discussion, it is initially valuable to visually understand what you mean. And that reinforces my assessment that it will not be approvable by the building authorities.
You envision something here that first creates a usable room depth for the living-dining room. That it does not continue the entire room width / house width may seem secondary to you – but objectively it is not.
What – since you only show the ground floor so far – is also not visible is whether this protrusion should be limited to the ground floor. By the way – just in passing – you also use the term incorrectly insofar as a bay window (Erker) would only be limited to the upper floor (and possibly above). On the (only or also) ground floor, it is a dormer (Zwerchhaus). And what would be approved as an exception by the development plan would be the classic glass box conservatory.

I am still waiting for a correct drawing from the architect, who will also include furniture etc. and optimize further.
Also missing is the correct thickness of the interior walls, only the exterior walls have the correct thickness.

I had already rightly assumed that by “architect” you mean a technical draftsman who professionally draws construction plans and puts your ideas into a finished form. But to a real architect without quotation marks, you should rather go with a list of rooms, requirements, and wishes, and the actual draft is then developed by her.

The red beam is supposed to represent the staircase, I couldn’t do it any other way.

You did that exactly right again: the finite element staircase as a black box, details are clarified in the working level.

Wrong order. You have many questions and those are questions to be asked of a professional, namely a , who also produces an approvable drawing with a functional house design.

Exactly so.

These are completely new traits of yours: you constantly appeal to those who present self-drawn floor plans to go to a real architect instead of pretending to be planners themselves. … and now something like this.

No, I am also referring the questioner here to a real architect. But he should not go to that architect with plans that nobody competent in the matter has assessed beforehand …

… and then also – without any indication – the insinuation that it would be a draftsman.

… namely exactly because of the suspicion that by “architect” no real architect is meant here, but for example (worst case, though frequently the case) a draftsman. We both know that the term architect in lay language has a deviating meaning, namely a kind of reverential label for a professionally involved person who handles building plans and translates customers’ wishes into the production process.

A bay window is technically called a projection. Projections are no longer explicitly mentioned (in NRW) if they do not exceed one third of the facade’s width.

A bay window is technically called a bay window – what the layperson usually calls a bay window is called a dormer (Zwerchhaus) professionally (and occasionally a layperson also means a risalit by "bay window"). As a group, they are called projections. They all share the characteristic that they are expected to be subordinate (which is not true in the desired case).

Furthermore, according to the building code NRW, they may protrude a maximum of 1.6 meters from the facade.

That is not a “but mommy allowed it” measure, but can indeed be restricted by a development plan.

Yes, only that it is not a bay window but an extension to a house. Since the conditions for one-third etc. are not met, I consider it not approvable. The architect should also know this. Also: if you plan such a massive extension, it affects the entire house design. So it is not as simple as “we’ll just include it”. Because without the extension, the living room does not work.

Full agreement.

This protrusion for the living-dining room clearly lacks subordination here, even if it would be planned to be limited to the ground floor.

If I had to assess the development plan conformity of the projection, I would (with regard to the exploited house width of 10.0 meters) approve a projection width of 3.3 meters (one-third limit maintained) and depth of 2.0 meters. If the predecessor plot was specifically promised approval for 3 x 3 meters, I would expect that here as well. But no more.

Besides, I advise the same as all other self-planners: 1. first develop the room program, 2. distribute it over the floors, and 3. start the floor plan layout definitely on the upper floor. And of course 4. leave the draft planning to an architect independent of construction companies, to whom you 5. only show your own sketches after she has developed a draft herself. Draftsmen who include building application documents never dissuade clients from big rubbish if it is approvable. The building authority checks only regulatory conformity, not design quality. There are no architecture critics there. ONLY for this reason I advised the OP to first ‘pre-wash’ his ideas here.

Now I really have to intervene here. The development plan says that.



So the boundary may be exceeded with a winter garden and balcony. Even by 3 m.
