Miss Iggy was charmed by the famed Amsterdam houses along the canals. They're narrow, have gables and tip forward. Apparently the forward lean doesn't just make the houses seem larger, but also makes it easier to lift objects up and into the house through the windows. Since the staircases are pretty narrow, an easy way of moving furniture was developed by putting hoists into the gable for lifting the objects. The tilt prevents the furniture from bumping into the housefront.
Pretty and practical!
