Online software for building a building?

Question

As in, I'd like to make a building and decorate it at will (much like in the Sims but more open ended and more options).

Is there a website where I could either download software or even better do it online? I am wanting to create a building from scratch basically.

Answer 1

do you want it in the format of a game or a CAD program (like architects use) if you want a CAD you might be able to find an education version of autodesk revit or something simmilar.

Answer 2

try using google sketch up. i know it's not a website but it is a great download!
