How can I make random procedural generate top down maps?

For now, I have two rooms..

I plan to put one more room, with closed walls and a closed door, in the north.

All rooms will be 320x180.

I would like to make a room where you start the game. (which in the photo is the room on the right)

I would like to make a phase change, upon entering the doorless entrance. (Second door [Right] in first image)

I would like to make a new room template, which will be the template with the closed door, where you leave.

I would like to make the rest of the map (1280x720) with several equal rooms, which would be the second room in the image (the room on the right)

The second room must be procedurally generated, until it no longer fits on the 1280x720 map...

I have no idea how to build this, could anyone help me?

NOTE: I have an event_sheet for procedural generation. And another event sheet for the game mechanics.

I have a layout to assemble the rooms.

A layout to store the rooms

A layout where the game will take place

A "bank" layout where I have the sprites placed.
