We have lived in current house for almost 9 years and desperately need more space downstairs. My issue with lounge has always been the odd shape, the fact it's a thoroughfare to rest of house and it's quite a dark space. We have always thought about squaring off the lounge and making a utility area out of that space and then knocking into integral garage. However there is still no way around thoroughfare and also we would have two nibs for joist. The other issue is the electrics box which is in garage and next to door into garage (220 cms along wall) which is also in porch (not shown on diagram) what would you do? The red line shows where we would square off lounge. I have thought about using garage as lounge but quite tight but with an opening to current lounge would it work???
