Hi, Was wondering what does it mean by building a3 star bagolow with no…

You have to build a three star bungalow and place decorations around it to achieve a 60% boost to it. Start with a chinese garden in a location that will affect both bungalows, then a park and a statue for each bungalow and finally a fountain and tree for each as well. That should get you more than the required 60%.
