The structure of this model is similar to many basic house models, except it is rotated to lie on the paper diagonally. The heart is formed using almost the same method as my Heart in a House (Flat) v1 model.
The opposite sides of the folded model are identical. Therefore, it is possible to fold variations with different proportions by shifting the ratios of the features.
