The best part about owning the Hunding Palatial Hall is getting access to a nice rooftop. Nothing beats warm summer nights partying with your guildies on the rooftop overlooking the ocean.
It takes a bit quite of work to set up a nice solution to getting there though... I went the scaffolding route with pillared blocks for support and long barnacled posts to support my makeshift platform. It's hard to align everything so people can walk up smoothly but the end result was worth it.
I'm curious if other folks managed to do this with things like stone spiral staircases etc... Lets get creative! Here's a pic of mine.
