The answer to the previous question might be interesting for all of you...

Yes - in your case, the scale can be smaller - BUT
you need to detail the structure and material at scale 1/50 (on the plate related to structure for example).
A specific level of detail comes with each scale and everyone should have documents at 1/50 (even if only partial).

You need to make proper plates for all documents.
Layout plans, sections, elevations and axos with name of the view, scale, orientation, plus all information necessary to understand your drawings.
AND, you need to have the context (choose what to show in relation to your project) on the drawings and eventually people, activities, animals, vegetation etc.

This is required for EVERYONE (each in a specific manner, depending on your project).

I recommend that you have a deep look at the RIBA Presidents Medals Student Awards website for inspiration on project presentation.

HERE for example, a very nice way to present your sketchbook.
