ᐅ Children's room with floor-to-ceiling windows

Hello everyone,
we are moving into a newly built ground floor apartment and have the choice between a room of 13.5 m² (145 sq ft) with floor-to-ceiling windows or a 15 m² (161 sq ft) room with regular windows to use as a bedroom or children’s room.
The larger room would fit the big bed and wardrobe better, but I don’t find floor-to-ceiling windows with doors opening to the garden ideal for a children’s room (ages 4 and 1).

What do you think?
Thanks and best regards

Install a lockable handle if not already present, and that should be sufficient.

Should both children share the room? Then I would lean towards the larger one. Otherwise, the 13 m² (140 sq ft) room is also fine for them. The great thing about floor-to-ceiling windows is that they can decorate and even paint them themselves. Our child really enjoys using window chalk occasionally.

There is also a third room of 14 m² (150 sq ft). I left it out earlier because it is intended as the child’s bedroom. So now, the competition is between the four-year-old and us.
The decorative aspect is nice.
The downside is that the two window sashes, each one meter (3.3 feet) wide, significantly reduce the usable space. That might not be a big issue if it’s used as a child’s room. However, I always prefer children’s rooms to be located further inside the apartment rather than near the entrance—the mentioned room with floor-to-ceiling windows is right by the apartment door...

By the age of 4, they manage to escape without you noticing, no matter which room they’re in. Our 2-year-old once ran past grandma completely unnoticed (I was standing nearby, amused). He went through the bathroom, the hallway, through the open-plan kitchen/living area (where grandma was), down the small staircase, through the main hallway, and suddenly into the garden. So the best advice is: always keep doors locked.

When choosing room locations, I would base it on your daily routines. In our house (a bungalow), the children’s bedrooms are closer to the main entrance than ours. This side faces the garden.
Reason 1: Evening visits to the garden don’t have to be especially quiet to avoid waking the children.
Reason 2: When I pack laundry in the bedroom, I have a view of the children in the garden.
Reason 3: From the living room, I can reach the children faster than from the bedroom (yes, I know 2 meters (6.5 feet) isn’t much).
Reason 4: I can keep an eye on the children’s rooms from the couch.

I would place the 1-year-old in the room closest to the bathroom. Short distances when taking them to the toilet are invaluable. Then, the second child can be placed in the smaller room at first. You can always swap rooms later if you find the other arrangement works better.

Thank you very much for the detailed responses.
Actually, everything really supports using the "room facing the garden" ourselves:

• We appreciate the view
• The children's rooms are next to each other and close to the bathroom
• From the living room, both rooms are in view
• We are near the front door

The only problem is that we can only fit a 1.80-meter (5 ft 11 in) wardrobe in the bedroom, which means we will need to allocate storage space in the children's rooms.
