There isn't much to see map wise, just put the front of the buildings as a rough thing, just the flat sides to show they were there without giving details. Building wise there is a chapel on the east side, rubble strewn but windows can be climbed into. The west side is the larger palace complex and that's the door the chaos space marine went into before this fight started. Right now there are no active hostiles in either building, gunned down or fled after having half their number taken out.
