to create a view toward the rural landscape in the yunnan province of china, olivier ottevaere + john lin have designed and realized a timber observation deck titled ‘the sweep’. constructed in just six days, the project was realized by a group of 65 students from the department of architecture at the university of hong kong. the structure is composed as a series of 12 trusses arranged tangentially around a central ring of posts. this organization results in a cantilevered donut-shaped platform, which slopes and gently curves to produce an engaged ascent for visitors. the climb up the slanting form culminates with an expansive panorama toward rice terraces in the valley below.

the donut-shaped deck slopes upward and gently curves to reach the elevated viewing point

located at the entrance to the local primary school, ‘the sweep’ has proven to be a highly used amenity for the community’s children and their parents. the framework becomes a playful structure for the students, while the platform serves as a waiting area, offering shade beneath its deck.

the platform is supported by 12 trusses, arranged tangentially around a central ring of posts

the cantilevered platform reaches a maximum width of 4 meters on either side

the timber floor surface flattens out at its top

the inclined nature of the structure produces an engages ascent

located near the local primary school, the structure has proven to be a highly used amenity for the community
