Design for Portable Cabin Buildings

I need a cohesive interior and exterior design for four portable cabin buildings: a cafe & reception area (1 Building), an indoor sport center (1 building), a snack shop (1 building), and toilets/bathrooms ( 1 building). The design should be inspired by the attached materials/inspo and should reflect a cozy yet sleek atmosphere.

Key Requirements/Expected Deliverables:
- 2 interior and 2 exterior designs for all specified buildings in accordance with the attached inspo (3D model)

Ideal skills and experience:
- Experience with portable structure design
- Strong portfolio in modern and rustic styles
- Ability to create cohesive designs across multiple buildings

Please provide portfolios showcasing relevant work.

Attached herewith:
- 3 inspo pics/designs (Our project is portable cabins, not containers so that should be taken into account)
- 3 pictures for our 3D Model, this is a render of our area/project without any design, feel free to utilize them if they will help you understand/get a feel for the project and aid you with creating the design.
- Quotation from the supplier so you can refer to the materials we are going to utilize to aid you in conducting the design.
- 2-D Plot plan of the area with the dimensions.
