The brief is a set of constraints, not a mood
A useful interiors brief records four things: how the space will be used across a day, who uses it and what they are sensitive to, what must be kept, and what the budget genuinely is. Everything visual follows from that. A family with two young children and a dog gets different flooring, different upholstery fabrics and different corner details than a couple who entertain twice a month, even if both love the same reference image.
For hospitality and retail the constraints are commercial: covers per hour, guest turnover, cleaning cycles, brand standards, fire and accessibility regulation, and the operator's replacement policy for soft goods. We write those down before any moodboard, because they eliminate whole categories of material and save weeks of design that would have been unbuildable.
Use pattern, sensitivities, what stays, and the real budget. Four constraints that decide every visual choice that follows.
