SA Power Networks has plans for a six-storey electricity substation in Adelaide CBD Artist Impressions of the substation planned for Eliza St, just off Waymouth St. Picture supplied by SA Power Networks. SA POWER Networks says a six-storey tall electricity substation in the CBD will be a work of art. Concept images show the eastern facade of the proposed 26m building in Eliza St, off Waymouth St, covered in a screen made from small metal discs fluttering in the breeze. More metal art panels would cover the ground level facade. Design firm Tectvs says the building "challenges what has been done in the past" with substations. "Electricity substations as a rule don't make civic statements or contribute greatly to the urban fabric," Tectvs says in a statement accompanying plans submitted to the Development Assessment Commission. (This) has been transformed from a usually mundane precast box into something that now also contributes to the cultural wellbeing of the city. The art screen, formed from many singular discs gently move in the wind, will give the building added dynamism. In a report for SA Power Networks to the commission, planning consultant Frank McIntyre says the substation will have "a very high standard of design, to such an extent that the whole of the building will be considered as a piece of art." While the substation will not be built until at least 2020, SA Power Networks says it needs to plan for the city's power needs. It says suitable properties are hard to come by and it wants speedy approval so the Eliza St property can be bought by the end of May. The new building would be predominantly black and grey and use a mix of glazed brick, precast concrete and metal louvres. The art screen and panels would be removable to allow access to the substation for repairs and upgrades. The wind-activated art piece, known as a "wind arbour," would be similar to one at Brisbane Airport. The City Messenger reported in November that Adelaide's first wind arbour would stretch over five storeys of Pruszinski Architects' new offices under construction on Flinders St. SA Power Networks is seeking planning approval that would be valid for 10 years. Written submissions to the Development Assessment Commission on the proposal must be made by May 9.
