Prior to her death in April 2016, Zaha Hadid's firm completed the D'Leedon complex in Singapore. The development comprises 7 residential towers, 12 semi-detached villas and integrated landscaping with recreation facilities.
Each of the seven towers taper inwards as they reach the ground to optimise public space with a unique petal-shaped layout which allows for windows on three sides of the apartments and cross-air flows to the living rooms and bedrooms as well as natural ventilation in all kitchens and bathrooms.
The generative floor plan of the petal changes shape along the height of the tower in relation to the different configuration and type of residential units. The changing composition of unit type enables the towers to respond to a series of parameters dictated by site conditions, internal organisation and structural optimisation.
An innovative concrete shuttering systems was developed to allow the construction of columns at varying angles. The balconies and the bay windows were pre-cast on site and craned to position to be bonded to the structure as the tower was climbing.
Double curved concrete façade panels were prefabricated from GRC off site, and used as permanent moulds giving a very high level of exterior finish to a complex geometry. The concrete was simply finished with render and white paint, leaving the floor structural joints marked. This simple surface treatment highlights the mass while providing the required level of consistency and quality of finishes that a high-end residential development demands.
Environmental considerations and the location along the equator determined the orientation of the towers along the East-West axis in order to optimise solar gain. Sustainable features were introduced to allow generation and re-use of energy on site and to minimise its consumption. The development was awarded Gold+ from Singapore's Building and Construction Authority (BCA) Green Mark Scheme for its design approach.
