Residential Renovation Singapore
Premier Home Transformation by Cosmos Decor
The Trusted Renovation Contractor in Singapore for HDB, Condo, and Landed Homes
Every Singaporean home has a story. Whether you are collecting keys to a brand-new 4-room BTO at Tengah, upgrading to a luxury condominium in District 9, or breathe new life into a resale HDB flat with high ceiling potential, your space should be more than just a floor plan.
Cosmos Decor is not just an interior design firm; we are a full-service residential renovation powerhouse. From cozy 3-room HDB flats to sprawling landed estates, we provide bespoke solutions that blend functional space planning with the latest 2026 design trends like Tactile Luxury and Modern Wabi-Sabi.
BTO RENOVATION
Getting your keys is just the start, we help you turn that empty "concrete box" into a cozy, move-in-ready home. Whether it’s a 3-room or 5-room BTO, we specialize in smart layouts and custom carpentry that makes every square foot count.

CONDO RENOVATION
Elevate your space with a touch of luxury interior design that complements your high-rise views. We focus on premium finishes and seamless built-ins that work within condo management rules, ensuring your home looks sophisticated without the renovation headache.
RESALE HDB RENOVATION
Don't let an old layout hold you back; we love the challenge of stripping down a resale flat to create something modern and fresh. From hacking walls for an open-concept vibe to updating old pipes and wiring, we handle the heavy lifting so your "old" house feels brand new.
