in order to see the house you have to download "buildings as props" and "rush hour as props" from the official Simcity 4 site. You have to register the game in order to download the files.
Ive tryed this modd and i couldnt get the boxes off like everybody else here. Instead i found RCI RH Plop Modd where every simcity 4 game building is available as a landmark (including all the CO $$$ buildings). to get it just type the name into simtropolis (or google). There are couple diff ones, if you find the one thats 4.8mb choose that one, thats where you can choose what buildings you want (residential, industrial) etc. glad to help, piece!
