We have removed some fitted drawers from the house we just moved into. Behind one of the units was this sloped angle for the staircase bulkhead.

I want to hide it away and would like to try and do it myself as it looks like a small job. What do I need to do to box this in? Will a wooden frame with a sheet of wood on top and plasterboard around the side do the job? Any pointers?
