21 Interior Studio brings together an experienced collective of interior architects, technical draughtsmen, and on-site project supervisors committed to transforming abstract spatial ideas into practical, long-lasting Singaporean homes.
Founded on the belief that a well-designed home should elevate daily well-being without financial ambiguity, 21 Interior Studio Pte Ltd has completed hundreds of residential transformations across Singapore's evolving housing landscape.
From tight 3-room HDB resale apartments requiring structural wall hacking to expansive private condominium penthouses, our team approaches every layout with technical rigor. We believe that true luxury lies in thoughtful ergonomics: seamless vinyl floor transitions, optimized galley kitchens, concealed electrical trunking, and carpentry joinery built to endure Singapore's tropical humidity.
How our operational model protects homeowners against typical industry pitfalls.
Conventional solo-contractor setups lead to communication bottlenecks and neglected site inspections. At 21 Interior Studio, every project is assigned a Primary Design Architect paired with a Technical Site Project Manager.
While the standard market contract in Singapore only covers 12 months, we stand behind our workmanship with a 24-month comprehensive defect guarantee across custom carpentry, plumbing joints, and masonry.
Choosing tiles, lighting, and sanitary ware in isolation frequently leads to site sizing errors and color clashes. Our designers physically accompany you to partner showrooms to ensure exact technical fit.
Consistently praised across 250+ reviews for honest communication, budget management, and meticulous site supervision.
