Having spent some time running around on the shard and browsing through the forums I see that there are a few other like-minded players when it comes to this topic. Also, Yes I do know that there is the screenshot forum with some custom house pictures on it, but I wanted to start a thread (and not necro-bump an extremely old one) that is dedicated entirely to not only custom buildings themselves but also the decor that fills these beautifully built homes and castles (or in some cases, dark and ominous crypts).
So I would like to start by listing my houses and hope others will also, whether it is just a room of your house or a particular custom deco piece/lockdown art, or your custom build etc. please feel free to share.
I will say that most of the deco I did in my house (including the building itself for that matter) started as something already on other sites (Castles and Courtyards is a big contributor here, any deco-nut I'm sure knows what I am referring to) but have modified a majority of it to suit my needs a little better (expanded on the idea, if you will).
Also, my couches are not finished, I am still tracking down pillows.
Top Floor with Hot tub, Bar and fountain (I forgot to turn of cricle trans for this one :/)

3rd Floor - Bedroom with Bigscreen TV(and remote), bathroom and walk in closet

2nd Floor - Living area w/fishtank, reading corner, entryway and patio

Ground Floor- Rune Library, Treasure vault, stable, kitchen

Outside View - Perhaps this answers the age old question of where the GMs go when they dissapear...
