A first conversation does not require a finished design. These questions explain what can be usefully prepared and what needs to remain open for assessment.
Do I need to choose a tile first?
No. A direction, a few references and a description of the room are enough for a useful initial brief. The actual product and finish should be confirmed before the written specification is final.
What should the photographs show?
Show the whole room, entrances and the finishes that meet the proposed work. Include useful context at a safe distance, and keep private documents and people outside the image.
Is the room drawing a construction detail?
No. The drawings explain relationships and choices. Dimensions, support, preparation and technical systems need a site-specific assessment.
Can the brief include an uncertainty?
Yes. Mark what has not been inspected and which product information is missing. Those notes help the installer identify what needs to be reviewed.
What belongs in a written scope?
Discuss inclusions, exclusions, preparation, material supply, access, the working sequence and questions that still need an answer. The provider should confirm the actual scope for your room.
Start with what you know.
There is space for the room, a material direction and the details you want to discuss. Your draft stays local until you choose how to use it.
