Your One-Stop HDB & Condo Interior Design in Singapore
BEYOND THE CONCRETE BOX
Bespoke Residential Renovation in Singapore
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.
At Cosmos Decor, we specialize in liveable luxury. By combining our in-house carpentry factory with 10 years of design expertise, we eliminate the middleman to provide factory-direct renovation pricing without compromising on that "showroom" finish.
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.
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.
