Since you've got the layout and dimensions of your space, why don't you make cutouts to represent your furniture and try some arrangements on paper? That's probably going to be better than any suggestions anyone could make on here without seeing the space and the scale of your furniture.

Since you've listed only the antique pieces it's difficult to figure out where everything should go. I assume you have a dining room table and chairs and not just two hutches (Do you really need both?). I'd use the angled walls between the kitchen and dining room for either the hutch(es) or the desk, bookcase, and maybe an armoire if it holds something like office supplies/crafts. How will each bedroom be used?

For those of us who don't follow metric, 190 cm long and 100 cm wide is 6.2 feet long by 3 feet wide.

So I understand you have a lot of antique furniture, but what other kind of furniture do you have? If you don't have a dining table, you could easily accommodate one of the hutches along the wall. You could create a cozy reading room with the second bedroom (if it is unoccupied) by placing the bookcase in there. If you'd rather display the bookcase, I think one of the armoires will have to go in the second bedroom.

We're currently trying to figure out the layout for an apartment we're building over the garage and I've been using this website http://floorplanner.com/ to make quick mock-ups, as we have a weird space. I find it helpful to have a 3D model to look at.

Are you sure that hutch is 100cm wide? That seems awfully big.
I am assuming that it is either just you or you and a partner and you will be using one bedroom as a spare bedroom.
I would put the smaller hutch on that angular wall, the other one in the spare bedroom.
The vanity goes in the bigger bedroom.
Use that weird angular space as your dining area (looks like you could fit a small round table there if you skip the barstools) and use the area labeled as "dining" as an office - with our antique desk and bookcase.
If there is room for one of the armoires near the entry? Otherwise, I'd say one armoire per bedroom.

As one with many antiques and hard to replace items I am quite attached to, I caution you to be very careful about what you rid yourself of. I got rid of a beautiful antique wrought iron daybed because it didn't fit in an apartment I was convinced I'd stay in for awhile. 6 months later, I moved, and could have used that piece in the new space. If it were me, I'd take more than I needed and then figure out what I can't live without...because once you get rid of a vintage or antique piece, it's likely gone forever.

It would seem logical to create a neat little dining area (perhaps with a gateleg table) right next to the kitchen, freeing up the entire living area for your antique hutches, armoires and bookcases.

Obviously you mean one hutch is 1,90m and the other is 1m wide.
I think the first comment makes perfect sense, but you'll have to convert feet to metres or vice-versa.

the biggest challenge I see is going down the hall to the living room while passing the kitchen. I would put a lot of emphasis on having a neat, aesthetic, kitchen that will make a great first impression. if it doesn't close off the space, perhaps hang a curtain to make the kitchen feel less obtrusive.

Not a suggestion, but a concern. It looks like the smaller bedroom doesn't have a window. Isn't that some kind of code violation?

Good point. It'd be a really claustrophobic space in that bedroom without a window. :(
