Sin Herh Construction Pte Ltd is a builder based at 2 Kallang Ave, #06-19 CT Hub @ Kallang, Kallang, Singapore, with a 4.9 rating on Google.
Building work in Singapore normally begins with a site visit, and any firm quotation should wait until a builder has actually seen the space. It is worth checking that a contractor holds the relevant BCA registration for the scope involved, since additions and structural alterations need permits a good builder will arrange. Sensible clients ask for an itemised written quotation with payments tied to milestones rather than a large sum up front. Anyone who has run a project before knows that a builder who explains the sequence of works and flags problems early is worth more than the cheapest quote.
For building projects around Kallang and the city fringe, Sin Herh Construction's CT Hub office on Kallang Avenue is a highly rated local option.
