Building something complex like a house involves long series of "Have to do X before you can do Y, have to install Z before you can do Y, have to finish A before you install Z..."I've been battling my way through such a sequence toward the end goal of installing the siding. Before I can install the siding, I need to install the door--thus completing dry-in--and its trim, and before I can install the door, I need to finish the wheel well boxes and entrance landing, to provide an elevated floor for the door to sit on.
And that landing is finally done!
