Capitalising on undulating site topography to create terraced landscape

SINGAPORE — SkyVille@Dawson and Waterway Ridges in Punggol are among the public housing projects being recognised by the Housing and Development Board (HDB) for “design and construction excellence” at an annual award ceremony this Thursday.

A winning project is Waterway Ridges by Surbana Jurong Consultants. Designers capitalised on the undulating site topography to create a terraced landscape, where the orientation and heights of the housing blocks were staggered to give the effect of “ridges” and to allow more views of the Punggol Waterway.

The Terrace EC is by the Punggol Waterway. Upcoming executive condo  launches include Anchorvale Lane EC while existing ones include Parc Life  EC, Signature At Yishun,  Brownstone EC, Visionaire EC, Inz Residence EC, The Criterion EC and Northwave EC, The Terrace EC,  The Vales EC, Hundred Palms Residences EC, Sol Acres EC and The Bellewoods EC.

A total of 23 projects by architectural consultants and building contractors won accolades this year — 11 for design and 12 for construction — with high-rise gardens and a terraced landscape enabling views of a waterway among the winning design features.

At SkyVille @ Dawson near Margaret Drive, there is a variety of community spaces designed in a park-like setting at different floors, for residents to interact with each other while enjoying the greenery, and clusters of homes share naturally ventilated gardens on high floors.

On the 47th floor, there is a roof garden with a 400m jogging track and seating areas, where residents may exercise while taking in views of the Queenstown estate.

Waterway Ridges is also the first public housing development with a large-scale integration of “water-sensitive” design elements, where there is an environmentally sustainable network of vegetated swales, bio-retention basins, and other features which help to treat surface run-off and enhance biodiversity, for example. This Built-to-Order (BTO) project has a network of footpaths and sheltered linkways as well as viewing decks, to enable residents to stroll or mingle within the development safely.

Apart from new housing projects, the HDB awards also recognise design work done to rejuvenate older estates. This year, the winning projects are two neighbourhood centres that were upgraded under the Remaking Our Heartland programme for the East Coast area, as well as the Neighbourhood Renewal Programme for Simei Street 1.

Under the construction award category, the HDB said that seven housing projects achieved Construction Quality Assessment System (Conquas) scores of over 90, above the national average of 88.5. This measure takes into account aspects such as workmanship, structural and mechanical and electrical works.

One winner in this category is Keat Hong Axis, a BTO project located at the junction of Choa Chu Kang Avenue 1 and 7, which has 1,130 flats and a multi-storey car park with a roof garden.

More efficient work processes and the use of precast components for the roof features instead of casting them on site helped to enhance construction productivity and quality, the HDB said. The project was undertaken by China Construction (South Pacific) Development Co, which achieved a Conquas score of 93.6.

The other five winners of the construction award include the building of Tanah Merah Staging Ground, a mechanised parking system at Bangkit Road and Yishun Avenue 4, as well as three upgrading projects.
