Tips for floor plan planning desired

Hello everyone,

I have been reading here for a while, but now it is time for my first post. I need some help with the floor plan planning for our new single-family house. At first, I planned to build a house with a basement to accommodate some hobby rooms (home cinema, workshop, sauna, ...), but I have since moved away from that idea and want to accommodate the required rooms on the ground floor/upper floor. Next week I am going to the developer, but before that, I wanted to sketch my/our ideas with the created floor plans.

It would be great if you had a few tips for me. Criticism is gladly accepted.

Thank you very much and best regards!

You seem to be a bit delusional? How much are you planning for your 350?qm large villa in euros? How is the floor area ratio/floor space index designed? A site plan would also be advantageous - including a north arrow! I’d rather say nothing about the floor plan, it seems a bit without concept to me. Regards

Sure, the bigger the house, the better. Just give every activity its own room. Then you line them up one after another and bam, the block is done. In terms of size, it could really be a colonial-era villa.

Just as a thought!
-Sauna separate; to shower through the dressing room, hallway into the bathroom?
- Cinema I assume with surround system and subwoofer next to the children's room?
- Office only accessible through the utility room
-...

Maybe better to have the architect or a professional planner take a look at it!

That won't work! Besides the points mentioned: How should the dressing room be furnished? How should the upstairs bathroom be drained? Other rooms also seem difficult to furnish to me. And you definitely need an office, guest room, hobby and cinema? And you want and can afford to pay for that?

Did you really think about the draft??? I mean, did you imagine what it’s like to live in it?

Office only accessible through the utility room? What is that??? Did you really PLAN with THAT IN MIND(!!!)? It doesn’t seem like it.
Sauna in the dressing room??? Hello, it’s often humid there; I don’t want my clothes always smelling like “sauna,” and after a sauna session, as mentioned before, walking sweaty through the dressing room and bedroom. Yeah, great plan, right???

To me, this doesn’t seem like a well-thought-out plan at all, but rather like a wishlist: everything you want is just listed one after the other.

I assume that you’re allowed and able to build that size (I assume you’ve put some brainpower into it), but does it make sense?
A palace like that also needs to be cleaned and maintained.
Well, if you can afford such a house, you can also afford a cleaning lady...

Cinema: is that your hobby or related to work? If it’s a hobby: I would seriously consider getting a good projector setup in the living room. How often will you use this “cinema”? Hardly daily, right? So it might be worth considering setting up a multifunctional room where you CAN ALSO watch movies.
What is planned in “Hobby”? Workshop? That would be rather unwise in the upper floor right in the middle of the living area.

There are some non-architects here who come up with pretty clever solutions (and there are some architect designs that are not clever at all, just to mention in passing...), but obviously you don’t quite have that knack. To be honest, I’ve never seen such a hair-raising draft.

Therefore: trust a professional planner. It can only get better.
