If this is a cloakroom, respect. Whoever has one, can.:)
We have about a 60cm deep and 150cm wide wall niche for the most important cloakroom. I built a floor-to-ceiling built-in wardrobe from a combination of hardware store side panels and Ikea fronts+interior. This way, our jackets and some of the little one's jackets are on hangers, and for the most important jackets, there are also pull-out hooks on the side that he can reach himself. Additionally, there are shelves for hats, scarves, etc., and shoe compartments below for the currently used shoes. Above the jacket area, there is storage space up to the ceiling. The entire wardrobe is flush with the wall. Under the stairs, we also have another shoe cabinet and a tall cupboard for less frequently used clothes and shoes.
With the knowledge I have now, I would probably build the built-in wardrobe a bit differently, but time was tight back then when we moved in.
