Make it a blueprint, a la Grounded. In this case, you can place down a blueprint of anything that you've learned. It would look like a ghost, see-through version of the item with a little quest marker on it. If you get close to it, it'll prompt you to make it. If you're within a certain distance to the crafting station, just holding the craft button on the ghostly object will craft and place it. If you have the object in your bank, inventory, or storage within the house you're in, it will instead place the object by taking it from that location, rather than crafting it.
Additionally, they could let you place blueprints of any item in the cash shop. The same thing applies as before, you can get close to the object and be prompted with a buy option, and holding the buy button will pull up the item in the cash shop with the purchase button. If you click the purchase button, it's automatically placed in your house.

This would allow you to preview items before crafting or buying them. This could even expand to items you don't have the blueprints for, which will remain ghostly and un-makeable until you have the blueprint. But that would add a lot of options to housing that I don't think Zos wants to put work into.
