Kachisi Kolandirira Alendo Mkati Concavity ndi Convexity ndi malo olandirira alendo a nsanjika ziwiri omwe ali ku Taoyuan, Taiwan. Mkati mwa nyumbayi mumaphatikiza mizere yakale ndi zipangizo zamakono. Mapale a nsalu za zitsulo (galvanized mesh) amagwiritsidwa ntchito ngati zophimba komanso monga denga mozungulira makwerero. Nsaluyi imalola kuwala kudutsa, kotero kuwala ndi mthunzi zimayenda pamakoma oyera. Njira yodutsamo yokhala ndi mikwingwirima yakuda ndi yoyera pamodzi ndi magalasi akuda imapanga chithunzithunzi chofanana ndi ngalande yapansi panthaka (tunnel). Denga lapangidwa ndi zojambulajambula zosakhala zofanana (asymmetrical carved collage) m'malo mwa kalongosoledwe kofanana. Kapangidwe kameneka kanauziridwa ndi zojambula za Pierre Soulages.
