If you ok with queen size bed, then it is possible to have a walk in wardrobe like this.

because of the 14ft bedroom length limitation, we suggest keep top row wardrobe to sliding type and the bottom wardrobe 450 to 500mm depth cabinet with adjustable shelving with folded clothes, shoe, towels, small items storage.

If you ok to have these wardrobe without doors covering, then it can help to make the walk in wardrobe feel wider.
