Very creatively designed Alien Research Bunker! :) It looks very great! Very nice outdoors areas with the vehicles and telescope for Sims to enjoy using. Very nice furnishing and layout of the underground levels! The research laboratory level is very great! The blue colour scheme and lighting, alien plants, and science themed items look great! Very nice design of the bottom basement living areas. The armchairs sitting area is very nice for Sims to enjoy watching tv. The aquariums are a nice touch. The atrium area with flowers is lovely!
You have designed the build very well! :)
