Building home in red zone Islamabad good or bad idea?

Building home in red zone islamabad is a good idea ? If yes then which sector do you recommend for family living 5-10 Marlas home , and how much will it cost for 5-10 Marlas according to your idea , please give your suggestions.

In ISB red zone there are mostly govt employee colonies and govt offices, there is no available plots in the sector F-5, E-5 or G-5 however the nearest residential areas are F-6 and G-6. F-6 mostly has 1 and 2 kanal houses and it costs between 20 crores to 50 crores, In G-6 mostly houses are minimum 10 marlas and will cost minimum 10 crores i think. Living in red zone is a nightmare, every other day there is some issue and all roads are closed.
