The Duchess Residences located at 110 Duchess Avenue, Singapore, with a total area of 14,000 sqm, was completed in 2011. The landscape design at Duchess seeks to create a piece of living landscape sculpture in 3-Dimension that responds and preserves the undulating terrain of the site, and to create a lush primeval Secret Garden, as a contemporary and exclusive setting for living. The Secret Garden contains 3-dimensional landforms and spaces which varies from the grand to the intimate in character, tying in with the major elements and functional concerns of the architecture. The landscape is also about a strong intimacy with nature through organic forms and the generous provisions of planting spaces in the form of Private Enclosed Spaces (PES), courtyards, terraces and planters integrated with water in an undulating ground terrain.
For the project Duchess Residences, the entire Hardscape, Waterfeatures and Softscape for the external Areas of the whole site was designed, documented and supervised by the STX Landscape Architects.
LANDSCAPE ELEMENTS AND IMPLEMENTATION
Facilities achieved within the development are : Entrance drop off oval Reﬂecting Pool with palms; Water Cascades at Basement entry; Oval roundabout canopy integrated with BBQ terrace and double level clubhouse; 50M Lap Pool (partially under Sun Deck); Elevated Jacuzzi and Children’s Pool (integrated with the Lap Pool); Long curvilinear Water Cascades; Bio Pond; Quiet Scent Garden.
The landscape is physically connected in space over 3 levels vertically from Drop-off at the Basement multi-function Room to the BBQ terrace at level 2.
Main Entrance Drop Off Lobby
At the main entrance, an oval shaped raised stainless steel reﬂecting pool with inﬁnity edge and palms in the water deﬁnes the focal of the drop off lobby. One side of the lobby is deﬁned by 2 planes of water walls which form a continuous arc with an opening in the center to create an entrance to the amenities beyond. Overhead across the drop off, a canopy echoing the oval form on ground opens up to the sky above. Palms in the reﬂecting pool punctuate the oval void and accentuate the vertical axis upwards. The oval canopy structure also forms a sculptural ramp with planters and integrated with the Pool and BBQ terraces.
Clubhouse Pool Deck
The pool deck nearest to the Clubhouse is the Clubhouse Pool Deck. It serves the Clubhouse and BBQ terrace, the main lap pool and children’s pool. Part of the pool deck opens up to a void where an arc of water wall brings light and animation to the courtyard of the Multi-function room below. While the Clubhouse is of 2 levels, the landscape is physically connected in space over 3 levels vertically.
The children’s pool is near to the Clubhouse. Water spigots are in the form of organ pipes as a design feature.
Main Lap Pool and Jacuzzis
The main lap pool is integrated with the other recreational pools to form a large organic naturalistic water body yet maintaining a 4 lane x 50m lap length for exercise swimming.
Water overﬂowing over the long edge of the pool visibly expresses the level change in the site in a long series of cascades fronting the frontage of the ground units.
An upper sun deck terrace slides over and forms a canopy over part of the main pool to create a sense of mystery and discovery. The terrace is punctuated by a void in its center to ﬁlter light softly down to the pool and planting below; it also connects the units at the highest level on site while providing an elevated viewing experience of the landscape.
The organic geometries and undulating planes are off-set in an artful manner from each other in space, and together by the intertwining of hardscape softscape and waterfeature elements provide a setting and ambience for living close to nature in a contemporary secret garden.
Pond and garden around Gym
As a contrast to the recreational pool areas, the garden terrace is a quieter space and takes a softer approach with its interplay between waterbodies and water plants. There are bio ponds in this area. The gym is located and ﬂoats in a reﬂecting pool. The planting for this area will be lush with vines on the retaining walls to create a quiet area of repose from the activity and relative formality of the other areas.
Quiet Scent Garden
At the north west corner of the site is a garden that will be planted with fragrant blooms and plant species. This is to create a quiet and secluded corner with seating away from the bustle of the main central landscape where the scents from the plants can be enjoyed at leisure. This garden can be a quiet reading corner also. At the other end is another smaller quiet scent garden.
ENVIRONMENTAL SENSITIVITY AND SUSTAINABILITY
With a severely undulating terrain with level changes both in the length and the breadth of the site, handicap accessibility was a challenge. As such multiple ramps at various gradients are integrated into the designed 3-Dimensional organic forms to reinforce the principles of Universal Design. Over 50 species of trees and palms were used to increase the bio-diversity of the site. A lot of large broadleaved evergreens were used to create a lush primeval character to reinforce an intimacy and closeness with Nature within a Secret Garden setting. The material palette used organizes the lighter beige colored materials for use on the horizontal plane while the darker green and black stones are used in the vertical planes. Lighter colors on the ground plane better accommodates bare- foot functionality for pool decks while darker verticals blend better with over- hanging plant materials.
Large trees, bushy palms and fast vines were used to provide shade and screening within the site to mitigate against heat gain within the outdoor landscape spaces. In total, the landscape was planted with 479 nos. of Trees, 822 palms, more than 25,000 nos. of tall / medium shrubs and close to 55,000 nos. of small shrubs / groundcovers.
