I tried my best to do an industrial laboratory for the study of plants and wildlife. I did not touch your walls but instead I used a celiling to connect the two separate shells.I hope that is ok.The build consists of a receptionist area or check in and and out area, a green house, workspace, bathrooms and a small upstairs green house along with an outdoor eating area. I hope you like it.#sydneymacoretta #sydmac #sydney #macoretta #shell #shellchallenge #shells #shellchallenges #sydmacshell3
