Halloweens Improved Storehouse

The Improved Storehouse in the upcoming Halloween event  is a nice item, offering drastically more storage space than a regular Store, offering 16,000 storage at time of writing as opposed to the regular 6,000 that normal stores have.

As a downside, the Improved Storehouse takes up a space 2 squares across, and 3 down (where most buildings only take up a 2x2 square. This makes the Storehouse tricky to place in any efficient manner.

I've been staring at the map for a while, and have come up with two decent locations for the storehouse.

In Sector 2 with your Copper mines, you can place it between the 2 mines on the left, and end up with 16 second travel times to the Storehouse for the close mines, and 28 seconds for the further one. Generally a good place for a Storehouse anyway, and not much else will fit with a regular storehouse either.
Edit: No longer true -> clicky

In Sector 5 (middle of the map), just below the Marble deposits you can make this setup. It's generally a wonky area of the map to fit things anyway, and the below layout fits the location exactly, and allows for 2 longer buildings (Watermills or Friaries) to fit to the right of the Storehouse.

The other numbers written down are for regular buildings to fit and tell you what walk time there is from that location.

A third good location eludes me for now.
