:brother: In that case building any sort of Mosque would be un-necessary anyway whether for men or women, because the only prayer which has been made compulsory to pray in the mosque is Salatul-Jumu'ah (the Friday Prayer) . . .
And that's not all; Jumu'ah applies to Women as well as Men. If it was compulsory for women to pray the friday prayer at the time of the Prophet (saw) and they prayed in masjid Fatimah; then why is it no longer compulsory. Are you saying that Islam has regular updates? (Na'uthubillah min thaalik) . . .
:shade: Please keep one thing in mind: the nature of Allah never changes; refer to Surah ar-Rum 30: verse 30 for details . . .
