French drain and existing drainage rock

I have some time off work to finally address this boggy space between my outbuilding (left in 1st pic) and house (right in 1st pic). The block foundation of the house stays consistently wet on this corner so some additional drainage is required. I asked the engineer who inspected the house when I bought it about a french drain and he agreed that should help. The level shows the slope of this area is toward the house. -My question is - should I leave some soil between the french drain and the drainage rock already set alongside the foundation? Should I put the drain right against the existing rock? Or something else? Thanks for the help! Breaking for lunch so I can answer questions for a bit (Pulled back landscaping fabric over existing rock for visual) submitted by /u/naplatty [link] [comments]
