How to pick the right one

• Portfolio fit: review 3–5 completed projects that match your style (photos matter).
• Budget & scope: ask for a ballpark budget range early (per sq.ft. or per-room) to avoid mismatched expectations.
• Process & deliverables: confirm whether the firm provides turnkey execution, procurement, site supervision, and a timeline.
• References and recent projects: request 1–2 client references and at least one recent site visit or walkthrough (photos or onsite).

Would you like a shorter shortlist (3 firms) tailored to a specific project type, budget, or area in Mumbai? If yes, tell me project type (apartment / villa / office), approximate budget, and neighborhood and I’ll produce a targeted 3-name shortlist with contact links and what each is best for.
