I get the feeling from the blog you can maybe renovate community lots.
If it’s like the sims 3 career (and you can bet it will be a poor man’s version) I would expect it to be room renovations rather than full house renovations.
The BB items look nice but most builders have already renovated the ugly as sim EA houses or downloaded new ones, myself included. And if I’m doing that I like doing it to my specification. A check list of items that probably clash horribly isn’t something I enjoy, (nor checklists in general which is why I struggle with sims 4)
Renovating houses and community lots isn’t new game play. Arguably it’s not game play for many. But the ability to build tiny homes was not a original concept and EA sold it back to the community for £10. This is the same thing. A stuff pack for game pack price.
The sims 4 should really rename its self at this stage to The Builds.
