| - | The total material cost of the Bloem prototype is therefore **€2061.89**. Most of this value comes from the structural and interior construction materials, especially the cork insulation, plywood panels, flooring, and seating structure.

| The structural and interior elements of the capsule are mainly sourced from building-material suppliers and wood specialists. Components such as cork insulation, wooden slats, plywood boards, brackets, and adhesives are purchased from suppliers that can provide materials in the required dimensions and in relatively short lead times. Whenever possible, local or regional suppliers are preferred, since this reduces transportation effort and simplifies replacement in case of damaged or unavailable items. | The structural and interior elements of the capsule are mainly sourced from building-material suppliers and wood specialists.
