I don't know of any online site. I did find this freeware download site. I haven't tried it, so cannot recommend any particular one. Learning to use a site can be time consuming, and difficult. I bought a supposedly simple one for home and garden planning several years that I still have difficulty with.
In this program you can create a home or garden that other people can visit and ejoy as well. If you want it to stay in the world while you are gone you would have to pay for some real estate, but it is still possible to create your scene and drop it down in the world whenever you visit. Hope this helps!
