I wonder why you let your draft be discussed here.
People point out the mistakes that are spontaneously recognizable there, they point out logical errors, etc., and you reject all criticism.
Complacency is a poor advisor.
What makes sense?
What does not?
Those are your questions.
It simply does not make sense to build voids in a children's floor. Of course, a void is great if you have the space for it. We also have one. But be it the sound: upstairs I hear the TV from downstairs louder than the one in the bedroom, and it won’t be different with you. Probably even more extreme, since you are also building an unfurnished hall downstairs. I wouldn’t want to criticize the 80 sqm (ultimately only 60 remain for kitchen, dining, and living if you subtract the hallway, but it is as it is: if you want to build one thing, it does not have to be sensible with the other).
And about the armored doors: you don’t just live in the room, you also want to go out into the hallway once in a while. Then in the evening you can feel pub chatter from below or pure action from the TV with full volume…
At least with us, I can’t sleep with normal TV sound – and I’m certainly not sensitive and don’t need sleep like a child.
Has the open staircase already been mentioned? I also find it great, totally my taste. We actually turned it additionally. But I wouldn’t want to put up with it at all if in 10 years the teenagers bring their buddies and gangs or still hang out in the room with them in the evening, and I’m sitting there with my husband in front of the TV and have to keep a posture because someone constantly hangs over my shoulder who isn’t family and gets juice from the fridge.
On the subject of wardrobes:
No, look at the recess at the utility room.
This recess is not an adequate wardrobe for 5 people. The jackets and shoes of all people in the house of all seasons plus bags, gloves, and scarves… calculate 60cm width per person with a floor-to-ceiling wardrobe plus a chest of drawers. Bigger is always possible.
Do people nowadays have a separate storage room for toys on the ground floor??
No, seriously, either some space is created in the utility room for it, or the closet in the guest room… or some things just stand around in the living room, no one minds
I agree with you on that: you certainly don’t need a separate storage room for toys. But you need storage space for waste glass, beverage crates, waste paper, yellow sack, tools, paint buckets, garden cushions, cleaning supplies, mop, vacuum cleaner, and ironing board, decorative stuff/seasonal decorations, suitcases, and so on…
With children, you then have the fleet of vehicles too. The utility room is not enough for everything anyway. You also want to wash laundry, and possibly there will be laundry that can’t go in a dryer. Your 10 sqm are too small for the technology and laundry of 5 people. Where should the laundry for ironing be stored? Surely you don’t want the dressing room full of baskets. So first you have to create space for the other things. And yes: the office can be used for that. But it will no longer be an office then. So I see a cluttered office room and a hallway filling with clothes. Will you still react that calmly when the living room also has to serve (I already see the drying rack standing between island and sofa). 10 sqm to 240 sqm is too little.
I see usable/living area at about 10%.
Then I am very open to a few suggestions
And no, just because someone points out mistakes, you don’t have to present a polished draft here.
My opinion on the draft:
There is a narrow and also long plot of land that is fully built on in width. If that is not enough: the house also gets “ears” in the form of carports on the left and right.
And since one can doubt whether that is sensible or whether there is a forced obsession with boring symmetry – both arguments are not successful.
The plot cries out for another house shape, namely a long one. The orientation is also perfect!
A few weeks ago, we had a similarly arranged floor plan with a parent section on the side. However, it was very tight in many corners because no more than 150 or 160 sqm was to be built. Here it is less tight at critical points, apparently because money, i.e. living space, doesn’t matter.
However, a large living room isn’t everything that makes a house generous. If the laundry has always to be shifted back and forth, there is no place to store tools or light bulbs in the house, the office is therefore eventually repurposed, the file folders can no longer be found due to chaos, then something was planned wrong here.
I do see good approaches in this draft, but only the initial phase of house planning. There is still a lot of need for action. First, one should plan a balanced use of ground floor and upper floor so that no staggered floor is needed. Then adjust the rooms to size. If a sauna is really going in the bathroom, then consider whether an exit to the garden could be sensible. The kitchen already has an exit for garbage, but I see rather the passage to the utility room, where you store waste glass and yellow sacks. Doesn’t matter…
Later, I would also plan the windows instead of simply placing copies in a row. The bay window, for example, will look disharmonious inside and outside for this reason. And since parts are located in the flat roof and these walls do not even exist in the upper floor, one should also pay attention to where the windows connect.
How do you come to that? I had this floor plan (with insignificant deviations) calculated turnkey by 6 different companies, and all are within this range.
I assume they looked at the square meters, roughly 250 sqm, and then calculated at 2000/sqm. Since it is Brandenburg, there is the “bonus” that incidentally the ancillary building costs are included.
Or do you already have a detailed offer? I see immense additional costs in terms of statics. This certainly does not concern just one beam, there must be a lot to be supported, otherwise the upper floor will not hold.
Also check the development plan to see if the floor space ratio can be increased by 50% through outbuildings. If not, then I don’t see a large terrace, no driveway, or you have to distribute the possible 250 sqm well over everything.
