The interior designer’s reasoning makes no sense at all, having the bed in the middle makes lots of wall room for fun stuff, even if you lose floor space it will make the room look bigger?
It makes the room look tiny, having the huge bed sticking out into the room, no matter what prints you put up, and what little kid is going to care about lots of room for ‘fun stuff’, whatever that is, on the walls? He’s just going to want as much floor space at possible to play.
Her ‘designer’ sounds a bit like Emily, more interested in how something looks than how it works practically for the inhabitant of the room.
Agree that the room is bland, like an teenagers room, you wouldn’t think it was a little boys room.
