I don't consider myself a builder (much less fully-competent at building), but I've never understood how (even in the Sim2) way Maxis / the Assorted EA "Studio" Teams, have implemented "stairs."
I can't understand why they can't get the code working to have a set of stairs work in a 4x4 grid.
Other than the fidgety implementation of stairs, I'm really satisfied with the current set of build tools (as of
Ambitions). I never much used "half-walls" nor "stages", but they'd be nice to have (because, stairs are so tricky).
And of course elevators, and circular-staircases (because, stairs are so tricky).

[I guess the only other thing I'd like is a button to invoke "buildcheats", I hardly EVER use cheats in-game. The only time I use them is during building, I can't honestly think of a single time I've used
any "testingcheats" while actually "playing" the game (unless one of my Sims is bugged, in which case I'm not playing my game any longer, I'm trying to figure out what to do to "fix" my bugged Sim!
