Page Structure of Catalogue Site

Hi,

Looking for advice on the best way to structure a catalogue/product based site on 7.1

Looking for a similar style style site to this one https://www.montage-interiors.com.au/. With a range of products that fall under different categories/collections, but most products have a large number of different configurations/options so are more of a 'product range' so to speak. So needs to be more of a catalogue style with photos & specifications rather than individual products with pricing and ecommerce. 

See attached for initial folder structure, each folder represents a category, and in each category there is multiple collections of different products. 

Would it be better to create pages as per the below with each collection/sub folder page leading to a page where i can display a range of thumbnails linking to each relevant individual product? (this would mean each specific product page would be a page in the unlinked section that would link to the relevant thumbnail. 

It would just mean i may have a large number of unlinked pages (50+) is this a good idea?

Or is there another way that would work better?
