Islamic missionary group Tablighi Jamaat and UK design firm Mangera Yvars Architects have proposed a massive new mosque for the London skyline to be built in time for the 2012 Olympics. The mosque is intended to hold 40,000 worshippers, with space for another 30,000 in the ancillary buildings; this is just 10,000 people shy of the total held by the planned Olympic stadium. But the mosque isn't just meant to be massive, it's designed to be as sustainable as possible.
The wind turbines built into the minarets get the most attention, but the facilities include a closed system for recycling the water used for ritual washing, a tidal power plant to take advantage of the mosque's riverside location, and combined heat and power (CHP) units and solar panels to generate any needed additional energy. The plans have yet to receive final approval, but the depiction at the architect's site (warning: horrible awful Flash interface) is worth the effort to check out.
The 180,000 m2 structure would look very little like a traditional mosque:
The project has adopted the idea of Dawat by physically and metaphorically reaching out to provide large urban connections which invite people into the building from West Ham station, The Greenway and beyond. Dawat space is an interstitial public space between the sanctum of the Mosque and the World outside. It is a place for Muslims and Non Muslims to interact, debate and promote a greater understanding between ideology, faith and humanity.
The project is controversial, however, and not just because of its £100 million price tag. The backing organization, Tablighi Jamaat, has been accused by the US government of links to more radical groups, something the organization denies. (It's worth noting that the UK has not sought to outlaw Tablighi, as it has done with other groups thought to have radical connections.) The Wikipedia entry on Tablighi provides a neutral discussion of the organization and its status, with links to both supportive and critical sites.
