About Us

Urban Greenery

HDB creates conducive living environments for residents by developing and implementing innovative greening solutions on rooftop and vertical facades. These solutions reduce heat emissions from building surfaces and improves the aesthetics of HDB estates.

 

PEG Roof Tray

The Prefabricated Extensive Green (PEG) Roof Tray System introduces greenery to the urban landscape by greening building rooftops and is designed to address the environmental concerns of many urbanised cities with limited green spaces.

By providing thermal insulation to the roof, the PEG system reduces surface/ ambient temperatures while serving as an added protective layer for the roof membrane. In addition, the added greenery reduces glare to surrounding blocks while promoting biodiversity in the rooftop living ecosystem.

Verti.Gro

The Verti.Gro vertical greenery system, developed and patented by HDB, is a modular, lightweight plant tray integrated with prefabricated steel mesh and climbers to form a vertical green wall.

This system offers flexibility, by letting natural daylight and ventilation enter the building. Various mesh profiles can also be formed to create a variety of unique designs.

Key Features

  HDB Image

  • Modular and Lightweight

    Verti.Gro plant trays can be easily assembled, dismantled and reused to facilitate future works or maintenance.

  • Prefabricated Solution

    Various mesh profiles can be prefabricated to fit different designs and enable ease of installation on-site.

  • Integrated Water Compartment

    Verti.Gro plant trays are designed with integrated water storage compartments, reducing the need for frequent irrigation.

Floating Wetlands System

The Floating Wetlands System intensifies greenery and brings nature closer to your doorstep.

Inspired by the strong and lightweight organic form of honeycombs, we created hexagonal modules which could join together in a compact manner to form “floating spaces” on water bodies.

The Floating Wetlands System is able to support the weight of plants and maintenance workers, while staying buoyant and stable - even when it is exposed to waves caused by passing boats. You can find the Floating Wetlands System at Punggol Waterway, and within selected future HDB projects.

Floating wetlands were installed at the mouth of the Waterway, near Sunset Bridge, as a welcoming gesture and to help soften the look of the concrete columns and look-out deck of the bridge.
