I need to draw plans of my house?

I agree with the above that you have really left it a bit late!
Your quickest way will be to do a rough pencil sketch based on a tracing or photocopy of your plot. I presume that you are applying for outline planning permission if you have left it this late!
A CAD program would be the best way to do it yourself but you would need to find a half-way decent one and then there is the learning curve .... CAD programs do take a little learning: the simple ones are not good enough for a planning application and the more sophisticated ones take time to learn - though the more familiar you are with technical drawing, the easier something like AutoCAD becomes.
Google do a free program called SketchUp Why do they call them 'Appartments' when they are all stuck together?
