1:100 ISOMETRIC IN A2 - HALVE SELECTED SITE ANALYSIS THE ENVELOPE OF THE CENTENNIAL GARDEN IS MUCH DEFINED BY THE ROOF GARDEN WHICH ENCLOSED THE RESERVOIR UNDERNEATH. WHILE BOTH PROGRAMS CO-EXISTED TO LET PEOPLE RELISH GREENERY AND KEEP IN TOUCH WITH IT. AS TO LET THE CONSTRUCTION OF THE GARDEN FEASIBLE ON TOP ON THE RESERVOIR, IT MUST BE VERY LIGHT, WELL-CONCEIVED AND WITH STRONG FOOTING OR IT WOULD JEOPARDIZE THE RUNNING OD RESERVOIR UNDERNEATH. FIG I: EXPLODED SECTION

SPACE CONTRAST THE SPACE UNDERNEATH IS ENCLOSED TO THE FULLEST , HAVING VERY HIGH DEGREE OF PRIVACY AND SECURITY. THE INFRASTRUCTURE THERE IS ROBUST AND PRAGMATIC, PURELY FUNCTIONAL, WHILE THE INFRASTRUCTURE ABOVE ON THE ROOF IS PRIMARILY ORNAMENTAL. THE SPACE CONTRAST WITHIN THE SITE IS SUBSTANTIAL. SCALE 1：50

SOAKY SOIL BASE THE TOPOGRAPHY ON THE ROOF IS PURELY ORNAMENTAL, FACILITATING THE AESTHETICS OF THE AMPHI-THEATRE AND DIRECTING ALL RAINWATER TO ONE DOWNSLOPE. WHILE THE DRAINAGE WITHIN SOIL BASE IS ALSO ONE-POINTCOVERGING, THESE TWO CONVERGING LAYERS HOLD UP THE FLOW OF RAINWATER. THE REST OF THE LAWN REMAINS SOAKY AND PROHIBIT PEOPLE FROM ENTERING.

WE HAVE REFERENCED ON TRANDITIONAL FARMLAND TERRACING ON HOW THEY DISPERSE WATER WHILE KEEPING THE PLANT HYDRATED. WE HAVE BEEN TRYING TO CREATE DISCRETE LEVELS, TRANSITTING LEVELS AND A COMBINED WAY.

RAIN DISTRIBUTION AND DRAINAGE

TREE NETWORK TREES ARE PRE-EXISTING FA C T O R AT LU N G F U S H A N THAT PRIMITIVELY REACTING TO RAIN. IT DISPERSES AND C O N V E R G E S R A I N WAT E R ACCORDING TO THE SPECIE AND TRANMITTANCE OF THE LEAFS. DUE TO UNPREDICTABLE FACTORS LIKE GROWTH OF TREE CROWNS, THE N E T W O R K I S C R E AT I N G A UNEVEN DISTRUBUTION OF RAIN REACHING TO THE GROUND. THE LAWN UNDER THE TREES DRIED OUT DUE TO OVERSHADING OF RAIN AND SUN.

NATURAL TOPOGRAHIC SHAPES CANOPY DRIP

FUNNEL-LIKE STEMFLOW

THE TREES ARE ORGANIC COMPONENTS AT THE SITES THAT COULD REACT WITH RAIN DISTINCTIVELY AS THEY ARE MUCH TALLER THAN THE MAN-MADE CANOPY. WHILE THEIR ABILITY TO SHADE RAINWATER AREN'T ABSOLUTE BUT CONDITIONAL DEPENDING ON THE AMOUNT OF RAIN, OPACITY OF LEAF (AND THEREFORE SEASONS) AND SHAPES OF CROWNS. THE STRUCTURES ARE VERY INTELLIGENT.

OBJECTIVE WE WERE WORKING TO DESIGN A TREE EXTENTION THAT COULD COLLECT AND REDIRECT RAINWATER, MIMIC THE VARIETY OF RAIN SHADING THAT TREE CROWN PERFORMS BY DESIGNING DIFFERNT TILTNESS, STEEPNESS AND CURVATURE. WE ALSO WANT TO CREATE A GRADUATION OF EXPERIENCE WITHIN THE SAME LEVEL, AND ACROSS THE LEVELS. ROOF

CONCLUSION IN THE FINAL STAGE, WE TRY TO FURTHER SIMPLIFY AND CONDENSED ALL THE IDEA WE HAVE ABOUT : VARIETY OF RAIN SHADING GRADUATION OF EXPERIENCE EVEN DISTRIBUTION OF WATER IT IS A SET OF ASCENDING ROOFS WITH DIFFERENT PRESET TILTNESS CONFORMING TO THE PROGRAM UNDERNEATH, WHILE DIRECTING WATER TO THE POOL EVENTUALLY.
