Poh Sia Construction & Engineering Pte. Ltd. is a builder at 27 Jln Asas in Bukit Panjang, Singapore, with a 4.3-star Google rating; its entry can be found on the Building and Construction Authority's online directory.
Hiring a builder in Singapore starts with the paperwork. Any firm you consider should be BCA-registered for the type of work involved, since general building, civil engineering and specialist structural work sit under separate registration headings, and alterations to an HDB flat need the board's approval first. Get an itemised written quotation, confirm insurance, and where you can, visit a finished job — how a builder leaves a site tells you plenty. It is also worth asking early how noise, dust and debris will be handled, because homes in established estates sit close to the neighbours.
For Bukit Panjang residents planning building or alteration work, a builder on Jln Asas keeps the first site visit close to home.
