This creation provides a kind of green wall construction of building comprising one exterior walls of buildings of what is arranged in an accommodation groove, which has an accommodating space, to accommodate an at least plant； And an aluminum expansion web, on the outside of setting what accommodation groove, and have plural hole so that the plant seeks connections with. Thereby, the thermal diffusivity by what aluminum expansion web is good, can avoid long-time heat build-up due to strong sunlight, it causes expansion web temperature excessively high, causes plant withered, in addition when the plant universe is withered to be replaced, or planting environment is when need to be safeguarded, conveniently can carry out operation in what accommodation groove together.本創作提供一種建築物綠牆結構，其包括一容置槽，係設置於一建築物外牆，該容置槽具有一容置空間，用以容置至少一植物；以及一鋁質擴張網，其設置於該容置槽外側，並具有複數孔隙以供該植物攀附。藉此，由於鋁質擴張網之散熱性佳，可避免因強烈日照而長時間聚熱，造成擴張網溫度過高，導致植物枯死，另外當植物乾枯而須替換時，或種植環境需進行維護時，可方便一併於容置槽中進行作業。
