Storage that lines up with the desks
Cupboards and bookcases for the storage that does not live under a desk. The units here are sized to match desking heights, which is what makes a wall of storage read as one piece rather than a collection.
Doors or open shelves
Doors hide contents, which matters more than people admit. Open shelving looks tidy in a photograph and rarely stays tidy in practice, so in any client facing space the safer choice is cupboards.
Open bookcases work where the contents are deliberately on show, or in a back office where nobody is being impressed.
Height is a design decision
Storage at desk height doubles as a surface and keeps sight lines open across an office. Full height storage holds far more but walls the space off. Most offices need some of each, and mixing them along one wall is usually better than choosing one.
Matching what you already own
Impulse Storage matches Impulse desking. High Gloss Furniture covers the more formal end with credenza tops and twin cupboards. If durability matters more than finish, steel storage takes knocks laminate does not survive.
