I'm big on deco - maybe you shouldn't have said anything. LOL
I want the druid deco things that someone made for Carpentry BOD rewards several months ago that were never implemented. They included the old style "Soul Stone."
Also the little fountains that are outside TC, near the mage armor models.
I'd love to see something like a yard deco that incorporates flowering cherry tree, hedging, flowers, nice marble benches and those fountains. Maybe with a couple of the yellow origami butterflies. A little garden retreat.

Something similar was made for auction I believe last year, that went with the cherry trees, and Calan had it. He was going to give it away but I think someone got it. Have seen two in game - one at Georgia's house and the other at one of my game house neighbors. Make a new one a little bit different for the deco room, but in a similar style.
The well that is in TC deco room is awesome. Saving up gold for that one. Well done!
The lamp posts in deco room should be made in different colors besides pink and turquoise. How about jewel tones in blue, purple, green, white?
A big white stone fireplace. You have all the other stone types except marble/white stone. The white wood stove is superb, and I have one.

But would prefer a big tall white stone fireplace and stove also for my kitchen. Not too fond of the "modern" designs of kitchen appliances in TC deco room. But the glass tables and stack cloth shelf are nice.
The brown vanity table in TC deco room needs to have a south facing available. Right now it's only available in E facing.
Being able to make house floors solid black would be cool too, without resorting to use uni-tub or black cloth stacked everywhere.
Tokuno style futon beds.
A waterfall bath that you can actually walk into for a house, sort of like a special hot tub. I made my own waterfall bath that +Jade seemed to really approve. Have since redesigned it to make it a bit smaller. (Ella's House from House Gates, top level - but still in construction mode. Needs more gold, plat rocks and petrified logs to complete design.

)
In OSI, there was an option to take different levels of completed treasure maps that are used to craft one giant wall map. I want that bad.

Please please please please. Both E and S facing. The item is called "Tattered Wall Map."
A "treasure room" deco item. Just the items themselves, and not including ground/floor tiles, so it would fit in any household design. Including jewels, gold piles, silver coin piles, copper coin piles, gold bars, silver bars.
A fisherman's deco item. Including large net, smaller net, anchor, some fish stuck in the nets, and a fishing pole.
Bring in the "male" decorative armor (we already have the pink/female version), hanging weapon displays, hanging bow/arrow display, in both E and S facing.
More cloth tables. I love the green cloth "tea tables" available in grave digging, but they are tiny. We should have longer tables, and in different cloth colors.
Some of these items should be included (IMO) in land treasure chests and SOS chests, to make it more interesting. Right now the only reason to fish is for a slight chance at getting something good, besides a rope. And in land t-map chests, only thing worth looking forward to is a chance at an arty in the top level chest.
If I knew how to create designs in RunUO/Pandora's Box, I could create beaucoup (lots) of stuff for people to vote on and then GMs can implement via deed format. It could save you a lot of time.

Made an attempt already and can't figure out how to combine the different elements together. No tutorial online for it that I can find.
