Interior design and architecture firms in Singapore operate in one of the most project-intensive built environment markets in Asia. With construction demand estimated between S$47 billion and S$53 billion in 2025 according to BCA projections, and renovation costs for F&B fit-outs alone ranging from S$80,000 to more than S$500,000 per project in 2026 according to specialist estimates, the volume of work flowing through design practices is significant.
The liability exposures that come with this work are equally significant, and they arrive from two directions: what the firm designs and specifies, and what happens in the built environment where it operates.
For architecture firms in Singapore, professional indemnity insurance is not merely advisable. Section 24 of the Architects Act 1991 requires every entity licensed to supply architectural services in Singapore to hold PI insurance against liability for any breach of professional duty arising from negligent acts, errors, or omissions by its directors, partners, or employees. This is a statutory requirement, not an optional best practice.
For interior design studios, graphic designers, product designers, and other creative disciplines operating below the threshold of the Architects Act, PI insurance is not mandated by statute. But the liability exposure exists regardless of whether a regulator requires the cover.
What professional indemnity covers for design firms
Professional indemnity insurance covers claims made against the firm for negligent acts, errors, or omissions in the course of providing professional services. For a design firm, the relevant scenarios span a wide range.
Design errors that cause physical harm. A structural specification error that results in a defect in the completed works. A material selection that fails to meet fire safety requirements. A space planning decision that creates a safety hazard. In each case, a claim against the firm arises from the professional act of design, not from an accident on a construction site.
Cost overruns attributed to design failures. Where a client's project exceeds the agreed budget because of errors in the design documentation, incomplete specifications, or failure to obtain required approvals, the client may hold the design firm responsible for the additional costs.
Delays caused by design deficiencies. A construction programme that is delayed because of inadequate or incorrect design documentation creates liquidated damages exposure for the contractor and consequential loss claims that the client may direct at the design firm.
Intellectual property disputes. Design work is intrinsically creative, and the boundaries between inspiration, reference, and imitation are not always clear. A claim that a design firm has used or reproduced a protected design element, a proprietary concept, or a trade dress in its deliverables creates a PI exposure.
Failure to obtain approvals. Design firms that advise on or manage regulatory submissions, including BCA, URA, SCDF, or HDB approvals, carry professional liability for errors in those submissions that delay or prevent the client's project from proceeding.

Public liability for on-site work
Design professionals regularly visit construction sites, client premises, and showrooms in the course of their work. Where a designer's presence on site contributes to an accident, or where a client or member of the public is injured during a site visit or presentation, the firm carries public liability exposure for that event.
Public liability insurance covers the firm's legal liability for accidental bodily injury to a third party or accidental damage to third-party property arising from its business activities. For a firm that works across multiple client sites and premises throughout the year, confirming that the policy's territorial scope and activity description covers all relevant locations and activities is important.
Some design commissions also involve overseeing contractors or coordinating site activities. Where the design firm has a coordination or supervision role, the boundary between professional liability for design services and public liability for site activities can become blurred. Both covers working together, with clear activity definitions, address this more effectively than either alone.

Cyber risk for design studios
Design firms hold substantial volumes of client data: project briefs, floor plans, budget documents, client preferences, and personal data about individual clients in the residential and private sector. They use cloud-based design software, collaborative platforms, and digital asset management systems that are accessible from multiple devices and locations.
Under Singapore's PDPA, any personal data held about clients, residential property owners, or members of the public must be protected with reasonable security arrangements. A data breach affecting a residential client whose home renovation plans, personal preferences, or financial information is exposed creates both a PDPA notification obligation and a significant personal and reputational consequence for the firm.
Ransomware targeting design firms is also a documented pattern globally. An attack that encrypts a firm's project files, client databases, and design asset library creates immediate operational disruption, missed submission deadlines, and the potential for PI claims from clients whose projects are delayed as a result.
Cyber insurance covers the first-party costs of an incident, including forensic investigation, data recovery, PDPA notification, and business interruption while systems are restored. Third-party liability for clients affected by the breach is also within scope.

WIC for design studio staff
For design firms that employ staff, WIC insurance is mandatory for all manual workers and for non-manual workers earning S$2,600 or less per month. Most design studio staff fall above the non-manual threshold, but junior designers, model makers, or workshop assistants may not. Confirming that WIC is in place for all eligible employees, with wage declarations that reflect actual earnings, is a compliance step that is sometimes overlooked in professional services firms that think of themselves as office-based rather than as employers of covered workers.
