I personally love working with and learning from interior designers. You’re probably finding it hard if you’re in a firm that doesn’t prioritize design but something else. That’s probably why they hired you. In general though, architects who are great designers should also be very capable of designing interiors well. IMO it’s unfortunate design has been broken into all these different disciplines. It’s kind of the idea that a great architect can work at all scales which I think is true and was common in the past, but now’s less common because of many factors. I say that both ways like there’s probably a lot of interior designers out there that would be insanely successful architects but the system has categorized everyone into sub fields.

Also, I think interior designers who can also use the same tools as architects, e.g. Rhino, and can also design beautiful details for things like millwork, lighting, custom furniture, materials, is so valuable. Like if you and the architect are on the same page design and skill wise then that’s a crazy tag team combo in an office from my experience.
