Floor plan for a single-family house with 200m² with a separate apartment 75 + basement 140m² + garage 56m²

It is not common for houses that spread out so much to have a full basement.

Anyone who has to save on the basement should ask themselves whether their budget matches their size expectations. For those whose income/wealth matches a large house, they can "if necessary" also fill the basement with investment wines.

Hmm, so right up front. I probably have not even 10% of the knowledge about building/planning etc. compared to my predecessors. But maybe my opinion will help you a bit for that reason (sort of from an outsider :) )
To me, the floor plans look like a labyrinth, sorry for the expression.
But right when entering the house I only see doors?! I start in a small hallway with stairs -> 2 doors. Then comes the first larger "room" with living and dining area.

Read your description again very slowly, then maybe you will notice yourself: You have unconsciously come behind the secret of the design. This is not meant to be a real house at all, but an adventure game. Before opening every door you have to craft a weapon. For passing through the door you either get bonus points, or it costs a life – depending on whether there is a zombie in the next room or not *ROTFL* *SCNR*

No real house is supposed to be planned here, but an adventure game.

Hehe…
At least here the walls are stacked on top of each other.

The flow of life and daily work is missing, combined with accurate separation of functional rooms, which is actually avoided nowadays.
But it’s not bad if there’s no architect inside a person. We’ve seen worse paintings here, e.g. Sims houses ;)

The OP is not the first bachelor planning and building a single-family house. I don't find it that bad either and know some who have done it. Even for an existing family of five, the planning is generous in terms of the number of rooms and free basement spaces. I would reduce that a bit in this area. With 3 children, work, house, and garden, there is not much time left for undisturbed hobbies in the basement room. I would plan the mother’s granny flat to be barrier-free. That works quite well nowadays and without a hospital-nursing home feel. The whole thing really looks like badly played Tetris. Create a room program and have an architect plan it. Better smaller and less DIY. You can’t plan for all eventualities. Usually, it works quite well with 2 children’s rooms, 1 guest-study room. In an emergency, you can extend and renovate.

Again: YOU can only have one story, so you need dormers to illuminate the middle windows. What you have drawn is two stories.

I understood it to mean that if 2/3 of the floor is under 2.3m, it is not considered a full story. Is something not measured from the outer edge here, but rather from the inner edge, inner dimension, room area? 2m (south under 2.3m) + 2m (north under 2.3m) = 4m of 12m are therefore below 2.3m. This means that exactly 2/3 are over 2.3m, so it is fulfilled. :confused:

Well… get out of the apartment comfort zone: the dining area takes the place of the chill area, because you don’t need daylight to watch TV. Southern light is even counterproductive. Children who mainly stay in the dining area need daylight for playing and crafting at the large table. And more than 115cm width to enter the garden. Besides, other residents also use the way to the garden, so 115cm can be called a bottleneck. Also, children playing in the garden should be able to be observed from inside over the stay area (kitchen) for a few years.

Thanks for this tip about switching the rooms, I hadn’t thought of that yet and this is the third correct hint about a mistake in my floor plan, many thanks for that. Exactly such tips/hints is what I was basically expecting.

The width of 115 is completely fine for me and I ask you again to answer me how wide a corridor should be? According to DIN 18040-2 a barrier-free corridor should be 120cm wide and I have almost 100% fulfilled that requirement.

Children in the garden should be observed for a few years from inside over the stay area (kitchen)

Thanks, that hint was already kindly given to me by Gregor_K and has already been incorporated. :)

That’s why you also forgot the chimney flues upstairs? ;)

Thanks, that is the fourth mistake in my draft, I thought of it in between but unfortunately forgot both times in the current draft. :( I will remember that in the new draft.

But for you the main closet is in the bedroom because the dressing room has so many doors that you can’t use it for its actual purpose or only fit a 2.5m closet. For me that is a walk-through room and poorly planned.

The main closet is in the dressing room (my closet is currently 90cm wide and contains everything and could be halved. Then the second person had a 2m closet for themselves. The secondary closet in the bedroom is for bed linen, towels, blankets etc. Where is my mistake here?

For me personally this is not logically planned, but everything is just somehow squeezed in. But if you like it that way and it is your dream house, then all is good.

What is that? So, what exactly:

[*]that the bathrooms are on top of each other?
[*]that all rooms have a window?
[*]the arrangement of the garage to the house? I have tried much, counter proposals were all worse for us.
[*]The ratio of children’s room size to the house?

Maybe you can give me better help after the new drafts thanks to the helpfulness of the other users?

The same game with the granny flat (circled in red) why is the door there? A 1m² corridor that consists only of doors?! Somehow you create unnecessarily small rooms/corridors with 100 doors. Every guest gets lost.
I’m just imagining if a guest asks for the toilet: 1 door right, then 2 left, in that corridor then clockwise the 3rd door right from there into the other corridor and the door opposite. Of course, exaggerated now, but I hope you get what I mean.

This is so the odor from the bathroom does not spread through the whole house, basically everyone I know does it like that. The room size is of course a bit too small, but every extra m² there is missing somewhere else.

Your simplicity has helped me a lot. :)

I understand your arguments at least much better than others, especially that you only talk about the floor plan here, helps me enormously. Thanks a lot for that. I have merged the two small corridors into one corridor now, at least I interpreted that from your answer about too many small rooms. I also removed the office downstairs and moved it upstairs. :)

You are basically building a small apartment for possible children -> 65m²! Incredible. The dressing room is completely wrongly planned too. Here again this labyrinth. You come up the stairs into a nice big corridor and then you go into the dressing room, which somehow represents the next center because from there you go into a total of 4 other rooms... My predecessors already said it. In your case it is no longer a dressing room but more a walk-through room / corridor.

Thank you for that as well, I have taken on board that four rooms are at least one too many, the laundry room has thus been dropped for a somewhat bigger dressing room. I also thought the kids’ rooms are too big but since previously only the number was discussed, I had no relation/feedback. I have now made the kids’ rooms somewhat smaller. Because of the sloping ceilings they will only be 12m² to 14m² big, with the slopes now as in the new draft.

The basement roughly the same – doors, doors, doors... you create walk-through rooms everywhere. From corridor to storage, from there to the utility room, from there to the cellar room.

So even as a layman I have never seen anything like this. I've seen many floor plans and tried to understand them since we ourselves had the house building topic and checked several general contractors. But basically nothing fits together here, unfortunately.

Further points:
- Why 2 saunas?!
- Relaxation rooms, fitness rooms, about 10 bathrooms, 100 doors etc. etc. I have already seen many smaller floor plans in this forum for much more money.

I have 0 knowledge of planning, as I said. But a bit about prices. THIS will NEVER be done with 700k. Even if the basement is omitted the budget won’t suffice.

Sorry for the harsh criticism. But this has nothing to do with serious planning. This all sounds like “I make the world as I like it.”

The basement was only an example/idea and also only added as a question. Katja has already talked me out of that very well (wish dream and cost estimate). ;)

But it’s not bad if a person is not an architect. We have seen worse paintings here, e.g. Sims houses ;)

Thanks for your encouraging words.

The OP is not the first single guy who plans and builds a single-family house. I don't find that so bad and know several who have done it.
Even for an existing family of 5 the planning is generous regarding the number of rooms and free basement rooms. I would reduce that a bit in that area. With 3 kids, job, house and garden there is not much time left for uninterrupted hobbies in the basement.
I would plan the mother’s granny flat barrier-free. That’s quite feasible now and without hospital/nursing home charm.

The whole thing really feels like badly played Tetris.
Create a room program and have an architect plan it.
Better smaller and less self-work.
You can’t plan for all eventualities. Usually, 2 children’s rooms, 1 guest-study room work quite well.
In emergencies, you can build on and rebuild.

Thanks also to you for your feedback, I have planned it somewhat more barrier-free. :)

How soon is the architect then? Is she authorized to draw?

She only started last year, but her boss will do it, as far as I understood. It’s not 100% certain if she will do it. She wants to have a template and then decide, and that’s why I am here in the forum.

You want to do the electrics yourself on 400sqm and surely also the garage? Have you ever done so much electrics yourself? Does anyone help you? You also want to do masonry and painting alone. How many years have you planned for the construction?

I was an industrial electrician and have helped out in house builds several times. I have planned 25 days vacation + 22 overtime hours + 14 flexitime days for this alone next year (my employer is not happy about it...). The house should be so far finished by spring the year after next that I can live downstairs. :) If the lady from the building authority bothers again, then it won’t work, of course. :rolleyes:

I understood it as if 2/3 of the floor are below 2.3m, it is not considered a full storey.

The other way around: the non-full storey in the attic may only have this height on less than two-thirds of the area of the ground floor or exceed it.

I have now combined the two small corridors into one corridor,

The quality leap happens clearly after the decimal point. You better go to an architect (with a room program, nothing more!). Or do you want to use the forum to refine your design to stamp-master maturity (or get a fee discount for it, already doing "preliminary work")? Please don’t take the question amiss: do you know personally?

I was an industrial electrician and had often helped with house construction. I have planned 25 days of vacation next year alone for this, plus 22 overtime hours, plus 14 flexitime days (my employer is not pleased about this...).

So about 42 days for masonry and electrical work?
I'm always in favor of not slowing down young enthusiasts, but here I see a bleak outlook. Such a huge house, even with occasional support from friends – I’d rather estimate 6 to 7 months, provided you keep your job.
