This is a cool idea. I'll have to see what else I can come up with for you to build.
Name of final build: Del Sol Valley Starter Home (or something to that effect)
Type of build : House/Residential lot
Theme or other instructions: Something fit for two teenage girls who are interested in fashion and acting.
Other: I have two teen girls that live in my rotational save, and I plan to have them move out of the home in San Myshuno (with their parents permission, of course) to Del Sol Valley so they can get started on their future careers (Style Influencer and Actress) and becoming famous. If it matters, both girls are half alien (they have blue skin, human eyes, and alien social interactions, but no powers). I don't really like the only uninhabited lot in Mirage Park, and I'm not a builder, so I'd love it if you could make something. You should be able to go a little over the $20,000 starter limit because, as I have two sims, they should start with $22,000. I don't mind if they won't have much left over after buying the house. I have all expansion, game, and stuff packs.
