Unique Interior Design is a direct renovation contractor for homeowners in Sembawang — a northern town that grew from the late 1990s, extended by the newer Canberra estate. Whether you've just collected a BTO or are renovating a resale flat, one in-house team handles the whole job: carpentry, tiling, electrical, plumbing, waterproofing, painting and finishing.
Sembawang has largely newer 4- and 5-room flats and executive condominiums, with Canberra adding a fresh wave of BTO homes.
Sembawang's relatively young flats mean renovations focus on personalising fairly modern layouts — carpentry, wardrobes and kitchen build-outs, feature walls and lighting — rather than the heavy structural work older estates require.
Getting there is straightforward: Sembawang is served by the North-South Line (Sembawang, Canberra), so booking a site visit and running the works day to day is easy for our team. We cover Sembawang Central, Canberra, Sembawang Springs and Wellington, and also work in nearby Woodlands and Yishun.
