Short for ‘Prefabricated Prefinished Volumetric Construction’ (a mouthful, we know), PPVC is building technology that will raise construction productivity and help you move into your Build-To-Order (BTO) flat more quickly.
PPVC — Prefabricated Prefinished Volumetric Construction
BTO flats built using PPVC come with floor and wall finishes, internal doors, window frames, sanitary fittings, and a basecoat of paint. With these items provided upfront, you can cut down on renovation works and move into your new home faster. What’s more, these finishes and fittings can be paid for with CPF monies, and/ or your housing loan.
HDB will launch more PPVC flats in the coming years, targeting to implement this technology in about a third of the BTO flats launched for the year. However, if you prefer to choose your own finishes and fittings, you can opt for non-PPVC flats where the Optional Component Scheme (OCS) will still be offered.
Pre-Fab VS. Pre-Cast
There are also other construction productivity measures that have been put in place to reduce the waiting time for your flat.
Pre-fabrication and precast are terms that are bandied about frequently when the topic of HDB flat construction comes up. That is not surprising, considering that HDB has been the industry leader in precast technology since the 1980s.
Here, components (such as walls, columns, beams, and planks) are manufactured offsite and then assembled at the worksite, thereby speeding up construction. HDB’s precast solutions are getting more advanced.
The use of PPVC was expanded to 35% of new flats launched in 2019. Prefabricated Bathroom Units (PBU) were also implemented in all new flats launched from the same year, where the bathroom units were pre-assembled off-site, completed with sanitary finishes.

Same Components, Different Designs
However, construction productivity begins even before the soil is dug. Right from the beginning, at the design stage, HDB has standardised as many of the building components and flat layouts as possible. This helps to improve the ease of construction and turnaround time. But no cookie-cutter look for HDB flats! Even with standardisation, HDB designs each precinct in a varied and interesting way to give it a unique identity.
HDB’s First PPVC Housing Project
Launched in 2016, Valley Spring @ Yishun is the housing project to be completed with PPVC. The Build-to-Order (BTO) project was completed in 2020, achieving a manpower savings of 37% compared to conventional construction.
