Bedroom design

This is an existing building.

Argh... mea culpa...

My girlfriend thinks the space is sufficient. The 336 cm wardrobe is divided into 3 parts, each 110 cm wide. Each part has one shelf and one clothes rail. The other wardrobe, exactly 225 cm wide, has two parts, each also 110 cm wide. So, from the start, we have a total of 5 shelves and 5 clothes rails available.
In two of the 110 cm segments of the wardrobe that stands against the wall, there would be 2 clothes rails per segment; we are both tall and can easily reach the upper rail, and on the lower clothes rail, which doesn’t require much height, we would hang trousers on hangers. In the third 110 cm segment against the wall, my girlfriend wants a T-division because she has a few long dresses and also 4 drawers.
In the narrow wardrobe, we would only put in shelves and pack T-shirts, sweaters, towels, sportswear, and bedding there. Since my girlfriend doesn’t like stacking clothes double-rowed anyway, no space will be wasted there. She assured me that it’s enough since the shoes go down to the basement or the wardrobe area. Winter jackets also get an extra wardrobe in the basement.
Would it be better to use hinged doors instead of 2 sliding doors for the wardrobe that acts as a room divider? It would look different visually, but would the wardrobe be more stable that way? It would be stabilized by the wooden panel at the back, which can also be screwed to the wall additionally.

In my opinion, with 2 clothes rails in a 221 cm high wardrobe, which also still has a small base area, there is no room for a shelf.

I myself have Pax wardrobes at 236 cm height and also use 2 rails per wardrobe. I'm tall, so my tops are sometimes longer. For me, 2 rails fit one above the other, so that everything really hangs without touching, but there is no room for a shelf anymore. You should check how much space is needed from the rail plus about 5 cm so that the hanger hook still fits over the rail down to the bottom edge of the hanging clothes.

I also hang a lot of T-shirts, etc.

For pants, I installed the special pull-out trouser rack from the Pax series.

I would rather install drawers in the shallow wardrobe. I use drawers for underwear, socks, etc.

I put sweaters in the special pull-out plastic containers with lids (small ventilation slots) from the Pax series.

Hello, yes, we are aware of the 2 clothes rails and shelves, they have simply been included from the beginning. Unfortunately, the trouser hanger from Ikea is only 96cm wide, whereas our wardrobe (it would be the Sinfonie Plus from Staud) is unfortunately 110cm wide each. There is indeed a trouser hanger for it, but unfortunately only in W 44 cm x D 47.5 cm for a hefty 120€..... :-((

I have a walk-in closet, it's really something nice
