P103 Riviera Station Office is a builder based at #01-01, 21A Tebing Ln in Punggol, and it holds a 5.0 Google rating. In Singapore, the trade's first hurdle is paperwork: works in HDB flats — hacking walls, replacing flooring — need the right licences and permits filed before any work begins. A good builder will inspect the site before quoting, give an itemised written estimate rather than a lump sum, and plan around estate practicalities such as approved renovation hours, goods-lift bookings and notices to neighbours, things that matter especially in a young, high-density town like Punggol. Regulars also suggest asking for photos of completed jobs and speaking to past clients before committing. From its office beside Riviera LRT station, this builder is well placed to serve homes across Punggol.
