About This Directory
This directory presents 25 established interior design firms operating across Singapore's residential renovation market in 2026. Information is compiled from public sources including company websites, government registries, review platforms, and business databases.
Each firm listing includes verifiable information: location, years of operation, specializations, publicly disclosed accreditations, and available review data. This directory is organized by service model to help homeowners find firms matching their specific renovation needs.
Understanding Singapore's 2026 Interior Design Landscape
Selecting an interior design partner in Singapore requires careful consideration of multiple factors including regulatory compliance, business track record, service scope, and pricing transparency. Singapore's renovation industry serves diverse homeowner segments from HDB BTO purchasers to luxury condominium owners and landed property residents.
Budget ranges vary significantly: HDB renovations typically span S$25,000 to S$82,000 depending on flat size and condition, while condominium projects range from S$40,000 for basic new unit customization to over S$100,000 for comprehensive resale unit overhauls.
The regulatory framework requires strict compliance with HDB guidelines for public housing renovations and Management Corporation rules for private properties. Understanding HDB renovation permit requirements remains essential, as unauthorized works can result in enforcement action and mandatory reinstatement to original condition.
Consumer protection mechanisms vary across firms. CaseTrust-RCMA accredited companies maintain performance bonds guaranteeing deposits, implement structured payment schedules, and provide formal dispute resolution channels. Non-accredited firms may offer competitive pricing but operate without these institutional safeguards.
Service Model Categories
Integrated Interior Design + Contractor Firms: These businesses combine interior design services with licensed contractor capabilities under unified management, handling both creative design and physical construction execution.
