ECO STAIRCASES 3 eco staircases to facilities the bird watching tours, tree walk and discovery of the nature across 3 sloping area with well vegetated plants and trees, and, habitation of birds, small animals and insects. ST-01 extends from the Camp’s Platform G Phase III BBQ Area to lower area downstairs. ST-02 extends from Platform G Phase III Assault Course Area to the Block B Group Hostel downstairs. ST-03 extends from the Phase I Road to Clubhouse downstairs. Environmental friendly design will be adopted for the staircase. The staircases will blend into the surrounding natural environment in order to minimize visual impact. Natural materials such as concrete, timber/ recycle timber will be used for construction of staircase. Energy saving LED lighting system, information board and signage system will be installed to create an educational path for public interest.

DESIGN EVOLUTION

CONCEPT

After conducting topographical survey for the site, the location of original scheme is illustrated as below sketch. LENGTH OF ACCESSIBLE RAMP According to Design Manual : Barrier Free Access 2008, the gradient of accessible ramp shall be max 1:12. To access level of 6m height, the length of ramp shall be at least 6m x 12 = 72m in length which excluding the width of intermediate landing. CONCERN ON STRUCTURAL SUPPORT In order to support the ramp structure, concrete footings would be constructed every 6m. Large extent of excavation for foundation system is unavoidable under the original scheme.

INTEGRATED ELEMENTS AS UNITY DESIGN By integrating the ramp and platform element as a whole design, a spiral ramp is used as circulation from 6m height platform to ground level, and embracing the tree as a centre point. REDUCE NUMBER OF STRUCTURAL SUPPORT Beneﬁt from spiral ramp system : number of columns and footings can be reduced, cost for site investigation, tree protection and site formation would be reduced.

On the other hand, the location of footings shall consider existing trees & underground utilities, which will limit the proﬁle of ramp design.

ORIGINAL SCHEME

JOURNEY EXPERIENCE Two levels of viewing platform providing anchor point for educational trail, the ramp will only serve for circulation purpose. This approach will induce congestion at the two platforms. Further enhancing journey experience for the ramp area will have to be further considered.

ENHANCE JOURNEY EXPERIENCE Visitors can travel from high level platform and observe tree crown level and ramp down surrounding the tree. Intermediate landing for the ramp providing several access points connecting to the climbing web will allow visitors to sit down and get closer to the tree.

SHELTER FROM WEATHER Covered area is only provided at platform area. The rest of the footpath area would be exposed to sunlight / rain and would attract less interested to access Tree House. COST EFFECTIVENESS Due to the large extent of excavation and the physical area of construction, the cost for site investigation, tree protection, site formation and the structure would be increased. Cost effective approach will have to be further considered.

Climbing web consisted of steel core rope allow visitors get closer to the tree or sit around and reserved space for growth of tree, to see, feel or even touch them. Observation platform at top level allow panorama view within the landscape area and connecting with a link bridge at high level. Enhance circulation for camp user which provide a short cut access within camp site.

SHELTER FROM WEATHER The spiral ramp approach will function as a self-shading from weather, and using recycled/ composite timber ﬁns as shading device will reduce solar heat gain and yet permeable for natural ventilation. MODULAR SYSTEM Both ramp and facade system will be in modular units which will reduce fabrication cost and stocking for spare parts.

REVISED SCHEME

Circular path surround existing tree allow visitors observe tree condition in 360o for educational purposes.

AN AUTONOMOUS RESTING SHELTER

APERTURED PAVILION SITE LOCATION : RUIN INSIDE LEI YUE MUN COSTAL DEFENCE MUSEUM DESIGN REQUIREMENT : STEEL PAVILION AREA : 80m2

MEMORIAL TO THE HISTORY OF HONG KONG DURING WWII AT THE SITE OF COASTAL DEFENSE AGAINST THE JAPANESE INVASION. A JOURNEY FROM LIGHT TO DARK SYMBOLISED BY THE GRADIENT OF PERFORATED PANELS OR THE SHADOWS OF A PAINFUL PAST. EVEN THOUGH ITS OCCUPATION WAS BRIEF COMPARED TO THE CENTURIES-LONG HISTORY OF HONG KONG, THE EXISTING STRUCTURE STANDS AS EVIDENCE OF THAT MOMENT IN TIME. MY INTERPRETATION AIMS TO ADAPT THE ORIGINAL RUINS, ENABLING THE PUBLIC TO EMBRACE THE HARROWING EXPERIENCE OF WWII.

ARTIFACTS OF HONG KONG'S ARCHITECTURAL HISTORY. THIS CONCEPT EMBRACES THE POSSIBILITY OF ADAPTIVE REUSE, CHALLENGING THE CONVENTIONAL NOTION OF COMPLETE DEMOLITION AND REBUILDING. BY PRESERVING AND TRANSFORMING EXISTING BUILDINGS, THEY BECOME SYMBOLIC EVIDENCE OF URBAN DEVELOPMENT, DEMONSTRATING THE INTEGRATION OF URBAN FABRICS WITH TRAFFIC INFRASTRUCTURES. THIS PROCESS, FROM ADOPTION TO TRANSFORMATION, REFLECTS THE DYNAMIC NATURE OF THE COMMUNITY ORGANISM WITHIN YAU MA TEI. THE ARCHITECTURE SERVES AS A VISUAL TESTAMENT TO THE INTERWOVEN GROWTH AND DEVELOPMENT OF THE NEIGHBORHOOD, CELEBRATING THE SYNERGY BETWEEN PAST AND PRESENT, AND HIGHLIGHTING THE IMPORTANCE OF SUSTAINABLE URBAN DESIGN AND PRESERVATION OF COLLECTIVE MEMORY. THROUGH THIS APPROACH, THE URBAN FABRIC OF YAU MA TEI BECOMES A LIVING NARRATIVE OF ITS RESIDENTS AND THEIR EVOLVING IDENTITY.

URBAN PROPOSITIONS IN HOUSING

IDENTITY / IDENTICAL (“/” symbol versus, between ratio of & or)

HOUSING IN TAI HANG, AN OLD URBAN DISTRICT UNDERGOING REDEVELOPMENT, SEEKS TO FIND ITS GENIUS LOCI, ITS PROTECTIVE SPIRIT. THE ESSENCE LIES IN THE COMMUNAL SPACE, WHICH SERVES AS A VITAL ELEMENT FOR THE NEIGHBOURHOOD. SOCIAL ACTIVITIES THRIVE AT STREET JUNCTIONS, SERVICE LANES, AND EXTENDED OUTDOOR SPACES WHERE BISTROS AND CAFES FIND THEIR PLACE. TAI HANG'S STREETS FUNCTION AS PUBLIC PLAZAS, FOSTERING SOCIAL INTERACTION THROUGH THE COMPLEXITY OF THE GRID STREET PATTERN, OFFERING DIVERSE JOURNEYS AND OPPORTUNITIES FOR CONNECTION. CONVERSELY, TYPICAL HIGH-RISE TOWERS DISCOURAGE SOCIAL INTERACTION, WITH POINT-TO-POINT TRANSPORTATION ISOLATING RESIDENTS FROM ONE ANOTHER. THE TREND OF REDEVELOPMENT FAVORS TOWERING STRUCTURES THAT DETACH FROM THE TAI HANG COMMUNITY, ERODING THE ORIGINAL STREET LIFE AND REPLACING IT WITH GIANT PODIUMS AND TOWERS LACKING INTERACTION AND INTERNAL INTERFACING SPACES. THE QUALITY OF LIVING IN SUCH HIGH-RISES OFTEN AMOUNTS TO TINY BALCONIES OR ORNAMENTAL CLUBHOUSES, RAISING QUESTIONS ABOUT THE FUTURE OF RESIDENTIAL LIVING. DRAWING INSPIRATION FROM THE SHOPHOUSE TYPOLOGY AND AIMING TO STRIKE A BALANCE BETWEEN HOUSING UNIT EFFICIENCY AND COMMUNAL SPACE, THE PROPOSED HYBRID TYPOLOGY SEEKS TO CREATE A FUTURE RESIDENTIAL TOWER FOR TAI HANG THAT EMBODIES EACH OTHRER.
