房子概况：2400多尺, 4 level split, 3 bedroom 2 bath.
Level 1: basement (same as living room)
Level 2: Picture 1 (Full bath, office, family room, bonus room and 2 car garage)
Level 3: Picture 2 (Kitchen, dinning room and living room)
Level 4: 3 bedroom 1 bath
office +bonus room完全是浪费了。bonus room原来是车库，后来被改建了, 然后增加了新的2车的车库。
设计1：5 bedroom。优点可以面对更多的租户。缺点，不能从车库进屋。这个缺点很大吗？
