Is in that a website that I can form a 3D or virtual garden or a house? It needs to be free!

It needs to be free!
Answers:    There are a couple of free ways you could create your 3d garden or house.

First, you could use a free 3d modeling program. You would obligation to install the program on your computer and then create your scene by 'drawing' next to 3d shapes. The output of one of these programs can be many different things - still imagery, animations, or even interactive applications.

The easiest to use of these free tools is called SketchUp and can be found at: sketchup.google.com. It is probably your best bet. If you obligation more options and flexibility, appropriate a look at Blender at: www.blender.org.

Another way to stir is to create your garden or home in a free multi-user online environment. The most popular one of these is SecondLife (www.secondlife.com). In this program you can create a home or garden that other ethnic group can visit and ejoy as all right. If you want it to stay in the world while you are gone you would enjoy to pay for some solid estate, but it is still possible to create your scene and drop it down in the world whenever you drop by.

Hope this helps!
I don't know of any online site. I did find this freeware download site. I haven't tried it, so cannot recommend any demanding 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 near.
