Through the re-interpretation of the ritual of paying final respect to the deceased, the design of the new Diamond Hill Crematorium aims to provide a calm, soothing and dignified place for the friends and relatives to face life's sad but unavoidable moments. This is achieved through the axial symmetrical disposition of the main service halls and the landscape podium; the carefully designed ceremonial path for the mourners with intimate spaces for quiet reflection; and the spiritual engagement of the building with the surrounding nature. The Reprovisioning of the Diamond Hill Crematorium was carried out in two phases. Phase 1 consisted of the construction of six cremators, two service halls with a capacity of 100 persons each, gardens of remembrance, lily ponds, automatic coffin transportation system and other associated facilities. Phase 2 consisted of the demolition of the old crematorium and at the space so released, constructed the remaining two service halls and other associated facilities.

The new Crematorium follows the existing site contour, facing south, and comprises 2 distinct zones accommodated on 2 levels: the ground floor level for vehicle drop-off and building services installations, and the podium level where service halls, lily ponds and landscaping area are located. The ceremonial path taken by the mourners is carefully designed, focusing on the serene and contemplative experience.

Through admission of natural lighting from skylights and slit windows, a calm, tranquil and warm ambience is created inside the service halls. The entrance and exit of each service hall are purposely segregated, avoiding the chances of different groups of mourners meeting each other and stirring up grievous emotions.

The podium is richly landscaped with trees and climbers. Coupled with the lily ponds with a sense of Zen, a peaceful ambience is thus achieved for quiet reflection. Friends and relatives can take a rest and pay tribute to the departed here before and after the ceremonies. Plants with bright colours and strong fragrances such as Osmanthus fragrans (Sweet Osmanthus) and Plumeria rubra var. acutifolia (Mexican frangipani) are selected for the gardens of remembrance so that mourners will be reminded of the beauty of nature and the celebration of life.

The new state-of-the-art cremators utilise advanced combustion and flue gas treatment technologies in order to ensure compliance with the relevant environmental standards. After cremation in the primary combustion chamber, the flue gas is led to the secondary combustion chamber maintained at 850C for the decomposition of residual particles. The flue gas, after further cooling, is then led to a filtration system that includes separators and additives to further remove the particles and harmful substances. Only then will the flue gas be released through the chimneys to the atmosphere. The new cremators are in full compliance with the Environmental Protection Department's requirements for the operation.

Other sustainable features of the building include the green roofs of the service halls which lower the roof surface temperature and the air-conditioning load of the halls, and the 'Qing Yan' smokeless joss paper burner for the cooling of smoke and the removal of fume and large smoke particles before dispersal.
