The lots are not ready yet, and they've been working on the area for a while, but Lorea Homes is building out a new subdivision on Rosenthal Pkwy, just outside of Lorena. They might have some 1 acre lots there.
Another place to take a look, if you haven't yet, is off of Southwinds Dr... around a mile south from Rosenthal Pkwy. There were 6 or 7 lots for sale there. I think there may have been a couple left the last time I drove by there. They are just within Lorena ISD.
The homes and lots within Royals Ranch on Rosenthal are nice as well.
Good luck finding something that fits your bucket!
