Housing design is a reflection of people habitation. In Hong Kong high rise housing solutions are necessities rather than the desired environment. It is formulated by the scarcity of land and the expanding population. This proposal is to offer a compromise solution by interlacing the high rise with medium rise. This provides a multiple choice for people who prefers to live in a medium rise environment and at the same time creating a more intimate courtyard spaces in-between the blocks eliminating the usual vast expanse of deserted & wind swept landscape in the case of a high rise only solution. Though the programme indicated a domestic plot ratio of 6.57 (max), but, when you take away the slope areas, the actual plot ratio on the remaining flat areas is near to 8.2. Needless to say that a desired mix of medium and low rise solution is out of the question which would otherwise be more appropriate in the hill and woodland environment of the Site.
The diagonal planning concept is developed out of consideration for the prevailing wind direction, maximum view all round, site and brief constraints. Individual block design gives maximum natural cross ventilation to all flats as well as the lift lobby area on all floors. The configuration of the block layout offered long distant view to all flats except a portion of those under 9 storeys. This arrangement is intended to create a medium rise environment where the inhibitants enjoy some distant overlooking with the comfort living near the ground. In Hong Kong overlooking amongst certain section of the community is enjoyed. It helps to build up a community spirit as well as provides some visual entertainment. The external rendering and staggering shape of the blocks reflects the colour and hill silhouette of the surrounding landscape.
To satisfy the accommodation required, some of the flats are near to the road and outside of the 70 dB(A) line. An 8m high lattice wall composing of cross laid precast concrete strips with planting trough at top of wall provides the necessary noise buffer effect at appropriate locations. With the creepers full grown, the wall will merge into the surrounding landscape.
Solar energy will be collected from panels mounted at the roof canopies on individual blocks and at the foot panel of each street lamp. In view of economic restrictions, it is proposed that solar energy collected will only supply public lighting and perhaps the water pumps. The structure is a simple wall and beam solution except in the two levels of car park where columns are used. There is no transfer element to cut cost. Pre-cast construction is contemplated in the bay window walls, stairs and other non-structural parts of the building. Likewise low flush toilets and recirculated waste water system will also be taken on board.
All in all, this proposal not only satisfied the brief but also provided a healthy, sustainable environment and an intimate community to live in.
