Honestly building it by hand and using CSG - It took roughly about 1-2 hours once I had a decent reference.
The interior I’ve been working on for just over a day atm because of work and not keen on the styles.
It uses metal But yeah, my point of it seeming bland.

It’s probably the lighting technology that you’re using. Try switching it to Future lighting and make sure your studio graphics level is set to something high so that Future lighting is rendered.
