I'm not getting defensive, I'm just listening to the tracks and pointing out why I don't think it's a valid comparison.
Both songs make use of 9ths in the chords, but the chords in Drapery go down from Cm(add9), Bb(add9) to Abm and back up, whereas Architect goes from Am(add9) to Cm(add9), up a minor third and the repeating that from the Bb up to Db.
So yes, texturally the chords sound similar, because it's the same chord type being used, but in a different harmonic progression for both songs. Rhythmically it's not the same at all (Drapery is clearly in 6/8, The Architect is .. not) and even the melodic line (which I said does sound similar) isn't remotely the same when you start analysing it. For instance, in Drapery it starts on the fifth of the underlying chord (G to Cmadd9) and in the Architect it starts on the ninth of the chord.
