Floor plan of corner terraced house in planning - suggestions for changes?

The open staircase will not look as nice as you hope. The style of the staircase is, of course, determined by the color and material and especially by the side balusters. Depending on how graceful, beautiful, or rustic they are crafted, the overall impression of the staircase varies.

I (because I have no children) completely left out the railing and only have a handrail on the wall and risers. It still looks better than the more expensive staircase with an ugly railing. The balusters there are so wide but without decorative elements that the staircase looks like a kindergarten one to the neighbors. Despite the open steps.

For an open staircase, I would definitely not sacrifice or plan less effectively the storage/useful space under the stairs in your house. The problem is already that there is very little space when entering. Why should you then give away the next best place for useful things just to be able to look under the stairs while going up?

Since I don't have children, I left out the railing completely and only have a handrail on the wall and risers. It still looks better than the more expensive staircase with an ugly railing. The balusters are so wide and without decorative elements that the staircase looks like a kindergarten setup in the neighbors' house. Despite the open steps.

I would never sacrifice or plan less effectively the storage/use space under the staircase for an open staircase in your house. The problem is already that there is very little space when you come in. So why should you give up the next best place for something useful just to be able to look at the floor under the stairs when going upstairs?

So I want to use the space under the stairs for baby stuff, toys, etc., maybe a coat rack with a few hooks or something else, but still keep it open. Since I have a closed kitchen, that area is already quite closed off, and I don't like how it looks visually. The only thing I find disturbing is the door issue upstairs, that is the only thing I want to change, and whether the attic, where we will have the connections for the bathroom, should still get the window on the gable side or not, since I want to use it as my office/additional cabinets for my gloves, stuff, etc.

I’ll post a picture from an acquaintance; we’re building with the same developer and the same house. There you can see how wide the hallway is, mine will be at most 10 cm narrower, and how his stairs look. Although his staircase was included with an extra charge of 1000 euros, since beech is specified in the construction description. I think the hallway is already very nice and wide, and you have to consider that a large, long shoe cabinet will fit in the hall. My parents have a basement and an attic; I was there today—so much junk they have there, sometimes I am glad not to have additional space like that, although I mourned the basement for a long time.

P.S. The hallway in the picture, which will be different in our case, is that we won’t have a door lintel and this narrowing, my wall goes the full hallway width up to the stairs where the kitchen door is. I’m giving up the possibility to close off the foyer but don’t find that a problem.

The annoying thing is really just the door upstairs in the office; the only solution I have is to take the narrow door, then everything else is as I want it, but I find it strange to have such a narrow door... then the room doesn’t feel quite fully functional to me.

Honestly, that doesn't convince me. Google "Abstellkammer unter der Treppe". There you can see examples of what it looks like.

This is roughly what my stair area looks like... and the space under the stairs. Sure, if I do something closed off, I have a lot of storage space, but I didn’t really want a closed staircase. I looked at open staircases and have to admit, there are both open and closed very beautiful staircases,... I also don’t know how much more the closed one costs, I’m thinking about it, I was too fixated on one idea for too long, maybe I’ll be convinced, but for storage space I have a huge property where a shed can go, a double garage that we still have to build, eventually, then a pantry, we don’t want 100 kids anyway, the house is big enough, in the attic I have that one small room where I want to put cabinets, then a utility room where you can certainly put cleaning supplies and a vacuum cleaner. I do miss an attic, but I still have to figure that out otherwise I can have a knee wall built in the studio upstairs...

But as I said, I’m thinking about it, googling ideas, someone has to tell me what possibilities remain, you have to accept some loss, I’ll probably have to give something up,... it’s often either/or in life, I just can’t decide. I was immediately on board with other tips, but here I haven’t found the optimal solution for me yet.

Well, in the end it should please you. If the open staircase is nicer for you, that is also important. And some people actually have less stuff than others. But I wouldn't count on running up to the attic for every water bottle or the current winter coat because there is no space downstairs.

A freezer compartment is to be installed in the storage room

What exactly is supposed to go into this very small storage room? I also once read something about shoes and jackets there, if I remember correctly. 3.11m² is really not much. You probably won’t want to fetch mop, broom, bucket, stick vacuum cleaner all the way from the 2nd floor every time. From my point of view, I wouldn’t waste the storage space under the stairs, as the rest is not generous!

Where are all the house connections (water, electricity, telecommunications) supposed to go? Should this be directly next to the front door? If yes, is the fuse box then also there as well as space for the router, switch, and patch panel, or have you planned another place for that?
