Cheapest after the rough planks are probably the Scavenged Plates from the CWC furnishing merchant.
But these are on the smaller side so they'll set you back in slots.


For a more organic look, you can use the Limestone Shelf furniture from the Summerset furnishing merchant, but it may take a bit to get a continuous flat wall from both sides (the bottom is flat; the top is curved).

Elsweyr Platform, Wooden Large and Elsweyr Wall, Rough Wooden are decently sized, cheap-ish to produce green quality walls, and are a step up from the 'wood planks' so they don't look as shoddy as those. Or maybe Solitude Shed, Wood Lean-To if you don't mind the wonkiness.


With the current price of furniture (esp. Heartwood) most walls have become more expensive to craft or buy from traders. But you may want to look at some of the larger ones (as you'll need less of them to cover a larger structure so they may be worth the price even though they're more expensive). Check out the 'Structures' subsection of this furnishing gallery/list: https://eso.mmo-fashion.com/furnishings/ , you may be able to find walls that you like and that also work for your budget.

I'm building a tower mostly out of Alinor Walls and Fences (there are regular and long versions of each). I get bonus height by flipping one and aligning it atop another; you can bury the wall's patterned molding or the fence's metal grating in the floor or ceiling if you want pure white bricks.

Both styles offer posts for separation (though they align well to look continuous), and the wall has a corner version that I've used to make cylindrical turrets.

All praxes are available via Legerdemain in Summerset (robbing houses, mostly found in trunks and such), or for sale on guild traders.Crafting them can get expensive if you don't have the materials: Mundane Runes, of course, but the Alinor style calls for 2 Culanda Lacquer, awarded for Summerset dailies and usually for sale at traders for 3-4k each.

Never looked for the items themselves at traders, but I'd imagine that those who can craft them make some gold selling batches of them.

Depending on where you're building and if you can see only one side or not, the Solitude Floor is a large rectange and the bottom of it is pretty nice wood.



Thanks to it's size, it can cover quite a bit of area
