Star Plus Building Construction Pte Ltd is a builder at 140 Teck Whye Lane in Choa Chu Kang, carrying a five-star Google rating. Engaging a builder in Singapore usually starts with paperwork rather than brickwork: alterations to an HDB flat need a registered renovation contractor, while structural or additions-and-alterations works call for a properly licensed builder and the right approvals. Good firms quote item by item — demolition, waterproofing, tiling, carpentry — so you can see where the money goes, and the careful ones test bathroom waterproofing before tiles go down, not after leaks appear. Older Teck Whye flats have their quirks, from worn screed to walls that cannot be hacked, so get advice early and insist on a written scope of works. For neighbours in Choa Chu Kang, having a builder on the doorstep at Teck Whye Lane makes that first conversation an easy one.
