Snacks are types of food that are very popular among Indonesian people today because they have practical value and are suitable for modern lifestyles. However, snacks generally contain high sugar and calories, which are not good for health. From these problems, Pick a Bite, as a startup, is offering healthy and delicious snack products served in a cake shop. This store has a tropical design concept in its interior, starting from the floor, walls, ceiling, and furniture. This research aims to create an interior design for Pick a Bite startup using sustainability materials. The method used in this research is a single case study. The colour scheme used in the interior concept departs from the colours of the company logo. At the same time, the concept of sustainable materials is contained in the selection of materials in the shop interior. The floors and furniture use a wood texture made of environmentally friendly synthetic materials. The walls use white brick wallpaper motifs to emphasize the natural elements, while the lights used on the ceiling are energy-efficient LEDs. Using sustainable materials aims to reduce the negative impact on the natural environment.
