How to Price Interior Design Services: Fee Models, Scope and Communicating Value
Short answer
Interior designers usually price using one of five models: hourly rates, a fixed fee per project or phase, a rate per square metre, a percentage of the project budget, or a hybrid of these. No model is right for every studio. The best choice depends on project type, how predictable the scope is and how you want clients to see your value. Whatever the model, a clear scope, defined phases, a limit on revisions and a confident proposal prevent most fee disputes. Marketing matters too: studios that are known for a clear specialism can usually charge with more confidence.

A worked example
Imagine a studio that quoted fixed fees for every project and kept losing money on homes with indecisive clients. It switches to a hybrid: fixed fees for concept and design, hourly for extra revisions and site visits, with a clear change process. Clients understand what they are paying for and the studio’s margins recover.

Why recognition beats lead volume for design practices
Most significant architecture and interior projects come from reputation, referrals and relationships rather than form fills. A practice that is known for a clear point of view, documented work and respected awards or press finds that clients arrive already convinced. That is why we build recognition first: every published case study, award and talk makes the next client conversation easier and shorter.
