This unit was created by/from the need to maximize square footage of primary, usable workspace for many standard office positions.
(I'm describing a type of office furniture design and the text is part of a large set of descriptive text next to the picture of the furniture).
Editor:
If you want to explain the reason for creating, a two word preposition may work well;
"This unit was created due to the need to maximize square footage..."
or
"This unit was created because of the need to maximize square footage..."
