Teambuild Construction Group is a builder at 9 Defu South Street 1, Singapore 533844, in Hougang's Defu industrial estate, holding a solid 4.4 Google rating. Construction work in Singapore is tightly regulated, so a good starting point with any builder is checking its licence grade with the Building and Construction Authority, which sets the size of contract a firm is allowed to take on. Larger projects also run on written scopes, staged progress payments and formal variations, so it pays to have every change documented before work proceeds. Site visits are normal practice, and regulars know that a builder's active sites — tidy, safe, well organised — usually say more about quality control than any brochure. For anyone in the Hougang area comparing contractors, this well-rated builder on Defu South Street 1 is a sensible first call.
