I like how the roof eaves in this v2 model overhang the sides of the house. The roof edge structure makes v2 much sturdier than Heart in a House (Freestanding) v1. Design-wise, v2 is essentially v1, but with the roof folded over to form eaves.
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.
Between freestanding v1, v2, and v3, my favorite version of House in a Heart to fold is freestanding v2. It has a unique appearance, but it also has simple reference points and is still straightforward to fold.
