UPDATE: 11th June 2019 – Yes, the Decentraland Builder tool was released in April 2019 and is now live. This makes it easy to build on any parcel of LAND without any coding knowledge. Just drag-and-drop!
This is in the Decentraland roadmap. It is something that is also currently being worked on third parties.
