What This Means (2025 FDD)
According to Bambu's 2025 Franchise Disclosure Document, a 'Vanilla Shell' or 'Gray Shell' space is essentially an unfinished space consisting of "four walls with utilities stubbed in." This type of space lacks existing infrastructure like a kitchen or plumbing, which are already present in a second-generation restaurant or QSR location.
For a prospective Bambu franchisee, choosing a Vanilla or Gray Shell location will significantly increase build-out costs. The FDD notes that build-out costs are much greater in these spaces because the franchisee must install all necessary infrastructure from scratch. The document estimates that leasehold improvements can range from $35,000 to $145,000, and the condition of the space is a major factor affecting these costs.
However, the FDD also mentions that landlords often provide a tenant improvement allowance or rent abatement to offset some or all of the build-out costs in Vanilla or Gray Shell spaces. This allowance can help mitigate the higher initial investment. The FDD advises franchisees to carefully review and negotiate the lease terms with the landlord to secure the best possible deal, as the availability of tenant improvement allowances can vary. Finding the best location and understanding the types of spaces available are crucial factors in managing build-out expenses for a Bambu franchise.
