Hi, newbie here. Mine is a 3-room HDB. Instead of painting, wallpaper, thinking of having the walls bare with some texture like those you see in designer shops.

Is there a name for this kind of wall design? Is it expensive? Think it will work, for example, with hardwood flooring?

Any information lead or recommendation of contractor will be much appreciated.

Painting would be the cheapest actually, followed by stickers design like blink or winkplay, then wallpaper.

I am not sure what you are referring to, but I suspect you mean texture like raw cement, or uneven finish, etc? I think such are considered feature walls and even more ex lor...
