House Planner

Are you planning to buy a new house or make from scratch? If you do, you can use FloorPlanner to help you design your new 'castle'. You can even share it to your friend and ask them their opinions. It uses a sweet combination of Flash and a little bit of AJAX, so make sure you have Flash player installed and Javascript turned on.

The registration is very simple. All you have to do is enter your email, password, and password confirmation. It will take you to the project page shortly after the registration is finished (it will only take seconds to complete it). When the loading is finished, you can start working on your new house of dream
