WHO ARE WE
ABOUT COSMOS DECOR
At Cosmos Decor, we believe your home should feel like you which is personal, warm, and designed for the way you truly live. We’re not just another renovation firm in Singapore. We’re a close-knit team of interior designers, creators, and master carpenters who get a genuine thrill from every “wow” moment when a client steps into their finished home.
Since 2015, we’ve been helping Singapore homeowners transform ordinary spaces into homes with heart. From cozy BTO flats and resale HDBs to elegant condos, our goal is simple to deliver high-end design and custom carpentry, without the middleman markup.
The Heart of Our Craft:
Our 17,400 sqft Workshop In SG
Our story began in 2001 with Hong Dat Engineering Pte Ltd, an electrical works specialist. We expanded into construction and renovation services with HD Contractor Pte Ltd in 2010, handling RC structures, wet trades, and A&A works. These successes led to the birth of Oneness Holding, encompassing diverse interior design arms such as Cosmos Décor, focusing on renovation and custom carpentry (built-in furniture) in Singapore.
From a humble 1,500 sqft workshop to a modern 17,400+ sqft carpentry facility in Defu Industrial City,
Inside, our team of skilled craftsmen use advanced CNC and ABS machines to turn raw materials into custom-made furniture that fits your space perfectly.
Because we own the workshop, you enjoy:
-
Direct Factory Pricing — no middlemen or inflated costs.
-
Total Quality Control — every cabinet and wardrobe is crafted, checked, and refined under one roof.
-
Faster Adjustments — if something needs tweaking, we handle it immediately — no waiting weeks for third-party contractors.
This is what we mean when we say: your home is built by us, from start to finish.
