I’m renovating my new HDB in CCK recently and was looking for a better way to design my Flat. Mr. Google says that this freeware called sweethome 3D is the answer. I tried it out myself and well, it’s a very nice piece of software. And the best thing is that it is a freeware. http://sweethome3d.sourceforge.net/

You have a plan view on the top right, that you can put in all the walls, furnitures and a 3D view that you can rotate any angle you like to see your new design. Cool!

Easy to use. No problem at all. Cheers.
