The kitchen took 4 * .5 = <<4*.5=2>>2 hours longer than the bedrooms

So the kitchen took 4 + 2 = <<4+2=6>>6 hours

The bedrooms took 3 * 4 = <<3*4=12>>12 hours

So the kitchen and bedrooms combined took 12 + 6 = <<12+6=18>>18 hours

The living room took 18 * 2 = <<18*2=36>>36 hours

So everything took a total of 18 + 36 = <<18+36=54>>54 hours
