Connecting a part with a part

[AIDANJHAWKINS3HJ6V]

Hello

Please see my screenshot of a plan view of the corner of my building

I want to separate both walls into parts and then connect the insulation that is the dark grey wall on the ouside. How can i connect theses two parts so I can finish the corner

Many thanks
