SUBLEVELING IN KINDERGARTEN

Y X

MAIN ROAD

SUBLEVELING IN KINDERGARTEN IS A CONSIDERATION OF INADEQUATE STAMINA OF CHIDREN CONSTANTLY TRAVELLING UP AND DOWN. WE COULD FIND THE FEATURE IN THIS KINDERGARTEN AND FOUND IT VERY EFFECTIVE AS WELL TO FURTHER DEFINE THE PURPOSE OF USAGE IN THE AREA.

BY COMPRESSING THE INTERVAL INTO SMALLER SUBLEVELS, THE SCHOOL CAN ALSO ADOPT TO THE SLOPED LANDSCAPE AND ENBED ROOMS INTO THE EARTH. PLUS THE DUAL FORMAT OF THE KINDERGARTEN ALLOWS A CLEARER DEFINITION OF SPACE AND COULD BRACE FOR MORE VARIETY OF ACTIVITIES THAT COULD BE CONDUCTED IN THE SCHOOL.

URBAN EDGE THE CHOSEN SITE IS LOCATED AT THE EDGE OF HAPPY VALLEY, CONSISTING A PART OF SUBURB AND A HILLSIDE. UP ON THE HILL THERE IS A HIKING TRAIL ACCOMPANY WITH SEVERAL ABANDONED PLATFORMS. THE HILL IS FULL OF RICH TOPOGRAPHIC ELEMENTS CREATING A INTERESTING HIKING EXPERIENCE. ALONG THE TRAIL WE SPOTTED HIKERS TRAVELLING AT DIFFERENT DIRECTION TO AVOID STEEP UPDRIFT OR SOMETIMES SEEK FOR IT IN THE HOPE OF GAINING EXCITEMENT.

WE WANT TO REVITALIZE THE ABANDONED MOUNTAIN SIDE AND EXAGGERATE THE SENCE OF SATISFACTION STUDENTS OR HIKERS COULD GAIN ALONG THE PROCESS OF CROSSING THE MOUNTAIN.

IMAGINATION OF IDEAL LEARNING ENVIRONMENT

D ESIGN

I N T E R AT I O N

DESIGN CONCEPT OUR SCHOOL IS CONSTRUCTED ON PRE-EXISTING HIKING PLATFORMS IN HAPPY VALLEY. IT CONSISTS OF 5 BUILDING BLOCKS ALONG THE HILLSIDE. PART OF EACH BUILDING COMPLEX IS CANTILEVERED AS TO MAXIMIZE AREA OF CONSTRUCTION AND AT THE SAME TIME PROVIDE SHADING TO THE HIKING TRAIL UNDERNEATH. AS TO ACHIEVE THE SPAN OF CANTILEVER, WE REFERENCED ON THE SUPPORTING SYSTEM OF SUSPENSION BRIDGE RANGED FROM 20-50M TO HOLD THE BUILDING BACK ONTO THE CONCRETE PLATFORMS. THE SUPPORTING TIMBER POST WOULD BE REINFORCED

BY STEEL BARS AS TO INCREASE TENSILE STRENGTH WHEN RECEIVING BENDING MOMENT FROM SUSPENSION CABLES.

DESIGN ITERATION VERSION 5 1:200

PLUS, WE TRIED TO INSULATE THE BUILDING AS MUCH AS POSSIBLE AS TO BRACE FOR EXTREME HEATING HAPPENING IN OUR SITE DURING SUMMERTIME.AS MOST OF OUR MAJOR FLOOR AREA IS DIRECTLY ATTACHING ONTO THE CONCRETE PLATFORM, WHICH HAS A RELATIVELY LOW SPECIFIC HEAT CAPACITY AMONG NON-METAL, IT WILL EASILY HEAT UP THE INTERIOR OF THE SCHOOL AFTER DIRECT SUNLIGHT DURING THE MORNING TIME. THUS, BOTH THE FLOORING AND TIMBER POSTS ARE INSULATED WITH FIBERGLASS AND THE FAÇADE IS INSULATED WITH POLYESTER FOAM CORE. WE HOPE TO MAINTAIN THE LEARNING ENVIRONMENT WITH MILD WEATHER IMPACT AS A HILLSIDE SCHOOL BUT NOT TO FULLY ENCLOSED THE BUILDING SUCH THAT IT LOSES THE ESSENCE OF BEING SURROUNDED WITH TOPOGRAPHICALLYRICH LANDSCAPE. IN ADDITION, WE HOPE THE USE OF TIMBER WOULD NOT DISRUPT BUT TO GO ALONG WITH THE NATURAL AMBIANCE OF THE JUNGLE, WHILE PROVIDES A STRUCTURALLY-STRONG BUILDING ENVELOPE AS A VERY EXPOSED BUILDING.

ODEL MAKING

CONCEPTUAL MODEL 1:400

THE IRREGULAR TOPOGRAPHY IS CASTED IN CONCRETE IN THE HOPE TO SHOE THE ROCKY AND HIGHLY ROBUST LANDSCAPE UP ALONG THE HILL. WE SETTLE THE CONCRETE FOR 1 HOUR-4 HOURS (DEPENDING ON THE SCALE) THE DRY UP AND BE MODABLE. THEN WE HAND SCULPT IT TO THE FORM WE HAD IN OUR HEAD ALONG WITH ROCK AND CHARCOAL TO ENHANCE THE QUALITY OF IMITATION.

READJUSTMENT IN THE MIDDLE OF OUR DESIGN PROCESS WE REENTER THE STAGE OF SITE ANALYSING TO GAIN FRESH TRIGGER OF IDEA. AS TO ACHIEVE THAT, WE HANDCRAFTED THE SITE TOPOGRAPHY WITH OUR MEMORY AND PERCEPTION TOWARDS THE SITE. LATER ON WE PUT ON SMALL WOODEN BLOCKS TO TEST OUT ALLOCATION OF THE BUILDINGS. AT LAST WE HAVE THE IDEA OF DEMOLISHING THE FACADE AND LET THE EXTERIOR PLANTATION ENCLOSE THE LEARNING SPACE. THIS IS TO PROVOKE STUDENT TO FURTHER EXPLORE ALONG THE HIKING ROUTE AND BE MOTIVATED TO STUDY.

SPECIFICATION TIMBER SCAFFOLDING FRAMEWORK FINISHED WITH WATERPROOFING LATEX PAINT, SUPPORTED WITH FRONT FOOTINGS INTO CONCRETE PLATFORMS PLUS SUSPENSIONCABLES PROVIDING BACKWARD MOMENT SOME OF THE FOOTINGS CANNOT GET REACH TO PRE-EXISTING CONCRETE PLATFORMS AND MIGHT NEED TO LAND ON LOOSE SOIL BASE. FOR SUCH CASE FOOTINGS NEED TO CONTINUE STRECHING UNTIL IT REACHES SUBSTANTIAL EARTH. STEEL BAR REINFORCEMENT IS NEEDED TO STRENGTHEN THE TIMBER COLUMN WHICH IS EXPERIENCING TENSION FROM SUSPENSION CABLE. IT WILL CONTINUE TO STRECH DOWN ALONG THE WHOLE COLUMN.
