There are plenty of programs on TV about how to make over your home, interior design, and generally create a more agreeable living environment.

Sweet Home 3D allows your imagination to run wild without costing you a cent or having to lift a finger (except to use your mouse of course). Sweet Home 3D is not just a useful interior design application, it's quite simply a hell of a lot fun, allowing you to mix and match furniture with ease, take virtual walks around your creations, and indulge yourself in designs you'd probably never be able to perform in real life.

Sweet Home 3D offers more than 50 different pieces of furniture, ranging from beds to lamps or tables, but you can import even more from the developer's website. To create your rooms, all you need to do is drag and drop elements into the grid view and you'll see them building up 3D in the viewing screen below. Once you've done this, use the virtual visit tool to get a 3D preview of what it looks like and talk a walk around.

These are the basics and iSweet Home 3D is extremely easy to get to grips with. Unfortunately, the graphics are not great - many pieces of furniture look blocky, but it's designed to give an idea of what an arrangement will look like rather than a perfect picture. You can take a photo of your finished design, which you can then send on to friends to view who won't need Sweet Home 3D to view it. The fact that it's based on Java shouldn't put you off either - it works very smoothly with virtually no delays in placing furniture or creating previews.

Sweet Home 3D is an excellent solution for all those that daydream about redesigning their home, or even for professionals that need a basic mock-up.
