The Sims 4 Get To Work will release with a brand new neighborhood called “Magnolia Promenade”. Additionally, the game will also expand on current neighborhoods by adding new environments within them.
From The Sim Scraper: Rather than taking your Sims to a new world, The Sims 4 Get to Work integrates new environments into the existing worlds in The Sims 4. The Sims 4 Get to Work also includes an entirely new neighborhood, Magnolia Promenade, which is made up of four new lots, three of which are retail. You can create retail lots in the existing neighborhoods or move existing venues into the new neighborhood. It’s all up to you! You can even live right next door to your retail store.
