The construction rules A♭7♯5 follows
Start from a triad
Root, 3rd and 5th, stacked in thirds. The 3rd makes it major or minor; the 5th makes it diminished or augmented when it moves.
A third on top makes a 7th chord
A major 7th over a major triad is maj7, a ♭7 is a dominant 7. Over minor you get m7 or m(maj7); over diminished, m7♭5 or the °7, whose 7th is lowered twice.
Alter a dominant for tension
Raise or lower the 5th or the 9th, or add a ♯11 or ♭13, and a dominant 7th pulls harder towards the next chord: G7♯9, G7♭9, G7♭13.
