DS9 used plastic pallets - one type could be seen in the infirmary [1] and IIRC ceilings were made from different ones

Even set that screams it repurposes some real life elements sometimes gives better overall impression than CGI surroundings. I miss that craftsman work from years ago.
Doctor Who after return in 2005 up until 2010 didn't had a big budget and thus sets, props were cheaply done but that exactly worked IMO for overall charm of that show.
