Multiplayer Map Design - Top Down Layouts

Following my mind mapping I created a couple of quick top down layout ideas using minimal detail, plotting out a map which would flow in a figure of eight, plotting out any building/room locations which could be used for general navigation and user familiarity, any points of cover or access points to a higher tier of the map itself.
From here I will develop a prototype blockout of my map, using the Ublock package provided, going from my top down layout drawings and building upward.
