Of course I used up all freshly purchased tiles and didn't have anything left for the porch and railing. But I also figured out what I need to add to my bungalow design. Right now it looks good if I take pictures from this angle. But if I need my camera to look up, like if the minifigure would look at the bungalow - there are grey hinges I'd better cover with tiles. It will look much better then.
LEGO is an addiction. No matter how many bricks you have and just purchased - you always need some more :)
