Interior Design in New York

A single-room concept can be a few weeks; a full-home design and fit-out runs months once furniture lead times, trades and approvals are factored in. The design phase is quick relative to procurement and installation — custom furniture and joinery are usually the long pole. Ask for a realistic timeline including lead times.

A clear scope: the rooms covered, deliverables (concept, mood boards, floor plans, spec/shopping list, elevations), number of revisions, the pricing model and whether product markup applies, the furnishings budget assumption, and project-management scope if they'll manage trades. Vague 'design services' with one number hides scope disputes.

For a single room you can often buy a few hours of consultation or an 'e-design' (online concept) package rather than full service — a fraction of the cost. Full-service design earns its fee on larger, complex or construction-involved projects where coordination and avoiding expensive mistakes matter most.

Usually not — the design fee buys the designer's time and expertise; furniture, materials and trades are separate and typically the bulk of the spend. Clarify whether the designer marks up procured items or passes trade discounts to you, and whether their fee is on top of or inside the furnishings budget.

Common models: hourly for advice and small jobs; a flat design fee for a defined room or project; a percentage of the build/furnishing budget for larger work; and product markup where the designer buys furnishings at trade price and marks up. Some blend these. Ask exactly how you'll be billed and whether product markup applies.

Hourly rates commonly run $100-200 (higher for top firms), with flat design fees of $2,000-12,000+ depending on scope, or a percentage of project cost. Full single-room design plus furnishings can reach $15,000-20,000 on an average budget once product is included.
