When I was at frog the odd interior architecture or retail program would come in but we weren’t known enough for it to make it a practice… got to work on some Sephora flagship stores though. Retail is the likely closest thing. Some of the more star type designers get more into architecture and interior architecture like Stark and Karim Rashid, and Dror: Dror / home
Heatherwick Studio does a lot of architecture, furniture, product… but none of the droopy biz consulting… do you really want to make million dollar powerpoint that don’t go anywhere anyway?
