Is this site a WordPress theme or a custom design?

Hello everyone,

I've found a website and I'm curious about if this site is a WordPress theme or a custom design. I really loved the design and I'm planning to use it in one of my projects. Here's the link of it: https://get.properties/

If you have any insights or thoughts, I'd love to hear them. Also, if you know of any other similar themes or resources, you can share them with me.

Thanks for your help! WordPress ...
