People on Facebook questioned why couldn't be allowed to continue gathering the resources to build the buildings. The 1 week time limit is pointless if you don't have any resources or SP. You should at least be able to get the resources to build the last buildings you haven't built. The fruit is no problem except the Pineapples and Passion Fruit but getting the Construction Coins is luck-based since most spins give you XP and/or Bananas and you need 170 coins total to build the last two buildings.
The Bungalow is the only building I missed but there's no way I can build it since I need 1,364 Social Points which would cost $100.
