SketchUp House Model from DWG

I have a complete .dwg of my house renovation and now need it rebuilt in SketchUp so I can explore design options. The emphasis is on the kitchen, lounge and the new sun-room; every wall, opening and ceiling change in these three spaces must be recreated highly detailed and perfectly to scale...
