Bahria Town Karachi Homes Questions

Dear members, I am in the process of sending my forms and payment for 200 sq yd house. I’ve contacted BTK’s representative in my country regarding home desing/ no of bedrooms/layout etc. But he is not able to provide that information. In addion, btk is charging 10% extra for corner, or west open or park facing. I am interested in west open but not sure about corner. Any advice?
