Princeton Junction and surrounding areas has new homes by Toll Brothers, Centex, KOR, and KHov, just to name a few. Depending on how close to the station you want to be will depend on who's homes you're looking at. However, be aware that the Princeton Junction train station has no room for new communters when it comes to parking. If you don't have someone who can take you back and forth then you have to do one of a couple things. First, look at the new construction on Bear Brook Road as it's literally in walking distance of the train station. Or you can look at places like Plainsboro that has commuter buses that will trainsport you over to the station as well.
Otherwise, Hamilton Township might be another option. It has a fairly new train station, plenty of new construction in the area, and is another hot spot for NYC commuters. Plus you'll find the homes and taxes might be a little cheaper.
