Combining a Refinery and Other Buildings

Hello! Its been a while since I've posted anything creative, but as the calendar starts to shift to Fall, my hobby and modeling time is back on the agenda again!  I started a small project to basically combine a couple of smaller kits, and the reconcile the mess I made from one of my earlier wiring jobs (so pay attention, here is yet another Quinntopia mistake you can learn from! :-).

Below are sections from my Walther's Refinery kit as well as some Lyddle End (Hornby?) industrial buildings.  As they sat together on my workbench while all the other parts of the layout were being removed, I thought that they all looked quite nice together and I should do something to combine them into one unit.
Additionally, I need to fix my original wiring solution that I had for the refinery.  As you can see in the photo below, each wire lead exited from the bottom of a structure.  This is a terrible arrangement as you then need to drill holes for each lead through the benchwork/tabletop!!  So this would be fixing by consolidation/soldering all the separate leads into (ultimately) one lead (so that only one hole is needed for the installation of this structure).
 So I've got most of the wiring, the base and my plan, I need to install some lampposts, add some details, paint the ground, etc...  All in all a really fun little project!  More details to come!
