Week 3 Update

From last week, it was suggested that I put a datum via sandbox. I tried but it always lags and crashes when I do it. I can only do it in little segments. I don't know the sandbox tools well either, I would like to mould it more into a better landscape. The last week, I've been busy finishing other assignments, and did not have much time to spend on this, but I made sure that I should have sufficient time before submission to work on this.

Things I know I need to do:
-more sandbox editing
-edit basement floor
-stairs from basement to upper level
-stairs from mid level to ground level
-use one of my own textures
-put textures in
