Another way to add depth to the spaces at the front of the house would be to widen the house. The back of the house could be extended all the way along. This would mean that the corridors would need to move as well. It makes better sense to move the front walls either side of the central bay forward. The issue then is what to do about the roof line. The extended sections could be left flat, capped with some sort of dormer. Or the roof could be raised and replaced. I'm not sure if we'll get permission to raise the roofline.
I considered lots of different house plan ideas. I suppose it's only natural given the fact that I really enjoy home design. On this page I reveal all the home design ideas that were considered during our design journey. Some ideas are mine. Some are from friends and family others came from our architects. Because they're only ideas, the sketches on this page are rough and ready, doodles really. The vast majority of these house plan ideas didn't end up in the final design. My hope is that some of the ideas here that I didn't use will give you some inspiration for your home design.
