If your company would like to maximise the available area or ceiling height within the warehouse or factory unit, you may consider approved racking systems which can allow your company to have more storage space that would not affect the gross floor area of the development.
This may be a better option as it would help to solve the problem without involving the gross floor area of the building. An experience and reliable racking contractor would be able to advise your company on what would be the ideal approved racking system for your industrial space.
