Need help finding a hell forge in the Underworld

So I heard that hell forges can be found in the red brick houses in The Underworld, but I keep getting confused with the obsidian brick houses. Help?

I've tried the dungeon but I couldn't find any. I'm on Xbox 360.

From the terraria wiki ():

Please note that in the console version, the Hellforge spawns in the Deep Underground, or right above the Underworld. This is fixed in the most recent update, but worlds generated prior to the update will still have hellforges above the underworld in the stone layer.

EDIT 1: Hellforges are NOT located in The Underworld, they're located in the level just above it and are often submerged in lava.

EDIT 2: official Terraria Wiki page for Hellforge says:

In the Console version, Hellforges can spawn just above the Underworld.
