Looking for archviz related tools

Hi all,

I'm looking for archviz related tools.
A while ago I came across a 'add-on' for Unity that was specifically build around archviz.
UI stuff for multiple menu's and alike, options to assign a material switcher to objects, camera tools, social media stuff etc. All build around prefabs and such, so easy d&d.

As usual I didn't bookmark the thing, and am looking for it since. Pretty sure it was a Dutch guy who built it, and also had a bunch of videos on YT.

If this sounds familiar to someone, please leave a comment.
Or if there's something out there that does the same thing, I'm all ears.

I've done some extensive searches here, and in the asset store, but came up dry so far.

cheers!
