Wordpress theme - Real estate - Appartment buildings - Portfolio + Sub Portfolio

Hi all,
I am looking for a specific Wordpress theme. One of my customers is building appartment buildings. The different appartment buildings can be seen as portfolio items (like most real estate themes). BUT, I need to also have a detail per appartment in the appartment building, let’s day a sub-portfolio item.
This website is what I need https://www.decon.immo/te-koop/trendz/ . Click on the link ‘Grondplan en prijzen bekijken’ and you will see the details of every appartment. It should be easy to manage the appartment buildings + the appartment itself.

Any idea somebody ?
Thanks for your reply

Such things you can get with some code and CSS. I don’t think that you will get out of box.
