Inside this large building, a major battle awaits. The whole building is empty except for the top floor, where a Rocket Grunt and Giovanni is waiting for your arrival. To reach these 2 guys, take the stairs directly to Silph Co F3 after entering, then step on the teleportation pad in the middle room that contains 2 pots of plant, and you will be teleport to the 7th floor. Next, step on the other teleportation pad within the same room and you will end up in Silph Co F11. Fight the Rocket Grunt and Giovanni, so that those Rocket Grunts will leave Saffron City, allowing you to access the Saffron Gym.
After winning the battle, leave this building and heal your Pokémon. Then head to Saffron Gym, which is the bigger gym building with a door.
