What is a scope of work (SOW) in interior projects?

A Scope of Work (SOW) in interior design projects is a formal document that clearly defines what work will be done, by whom, and to what standard. It establishes the boundaries of the project, listing specific tasks, deliverables, areas covered, and exclusions serving as the foundation for both the design contract and the BOQ.

What an Interior SOW Covers

• Rooms and areas included in the project (e.g., 2 bedrooms, kitchen, living room)
• Specific work items for each area (false ceiling, modular kitchen, flooring, etc.)
• Design deliverables (2D plans, 3D visualisations, working drawings)
• Material specifications and brand standards
• Work that is explicitly excluded from the scope
• Third-party vendor responsibilities (e.g., builder's civil work not included)
• Site visit schedule and designer's on-site supervision frequency

SOW vs. BOQ — Key Difference

• SOW defines WHAT will be done and its quality/specification
• BOQ defines HOW MUCH it will cost for each item in the SOW
• Both documents work together and are often attached to the contract

The Scope of Work is as critical as the design itself a beautifully designed interior can become a source of disputes if the scope is not documented. Always review the SOW carefully and ask for clarification on any ambiguity before signing off.
