I can't explain why but your Pleasantview has a big Belladonna Cove vibe for some reason.
So I think that a more industrial style could totally fit here, like if it used to be the industrial part of Pleasantview but now it as been renovated into houses and apartments.
So you could totally go with a huge apartment that used to be a factory back then. Or you coud also go for a community lot with restaurants and shops inside... Like you can do whatever you wan with a big building like that, which is cool.
Houses around it could try to imitate the style with red bricks and black windows. Which is nice with that style is that you can do a bit whatever you want with it, you can go full modern everywhere, either black or white, you can put a lot of greenery or none of them, having only one part being full of bricks and the rest is a more traditional house, etc... I almost always go for that type of style when I try to make modern houses in the Sims 2 because it just works so well.
Another style I saw and that I really liked because it still gives this "exotic" vibe like the originals condos, it's this one with a lot of white and wood colors, plus I do think there is a window in the For Rent pack you just converted that could totally works there, and which is cool is that from far away it looks like a classic modern house, but when you're near it you can see all the motifs and complexity of the building
A last one that is a bit more Sims core, but the condos in Sunet Valley were kinda cool, even if the colors weren't the best, the shapes were fun and could totally fit there.
Hope it helped you in any way!
