Is there a mn type place but specifically for housey stuff?

[PrincessPilolevuofTONGA]

I know of, and use various DIY forums.

I know of houzz but it's pretty quiet and a bit, I don't know...aspirational?

This bit of mn is good but pretty small

I want a big, busy forum for DIY / decorating/ buying house stuff

Is there one?

Have you tried the USA settings for Houzz - much busier !!!

You are best looking by trade. E.g there are busy plumbing, electrics, tiling, plastering forums rather than one for all. Some on MSE too.
