A niche cake shop on the inside and a wooden wonder on the outside, SunnyHills cake shop in Minami-Aoyama, Japan takes timber construction to new heights.

Specialised in selling pineapple cake, a popular sweet treat in Taiwan, SunnyHills features an intricate three-dimensional external wooden lattice structure.

Well-known wood builder Kengo Kuma of Kengo Kuma & Associates modelled the building after a bamboo basket and carried the effect inside.

With a total floor area of over 290, the structure is built according to a joint system technique called Jigoku-gumi, a traditional method used in Japanese wooden architecture.

This technique joins wooden slats without the use of glue or nails. Vertical and cross pieces in the same width are entwined in each other to form a muntin grid.
