Hi @Sunny1995,
Welcome to the Bunnings Workshop community, it is fantastic to have you with us.
We would need some further details in order to assist with this kind of project.
Is it possible to get some photos of the office and the basic location of the wall?
Is this in a residential setting? Or a commercial office space?
What sort of finish are you looking for? A simple plasterboard wall with timber or aluminium window frames? Or full-height glass that acts as the partition?
I used to work for a builder who specialised in commercial ceilings and partitions, using a lot of aluminium and glass, and from experience, I wouldn't call it a DIY project.
I would be happy to offer you guidance on planning the project, but depending on the context, it is likely one that is best left to the professionals.
I'll wait for further details.
Jacob
