The KM3NeT project is aiming to produce the most sensitive neutrino telescope ever built. Its envisagedlocation in the deep Mediterranean Sea optimizes the sensitivity for neutrino sources near the Galactic centre. Duringthe past year a number of major decisions have been made on technical implementations. We have adopted an opticalmodule (DOM) configuration housing many small photomultipliers rather than earlier traditional designs having asingle large PMT. The readout electronics is incorporated into this digital optical module. The site-to-shore commu-nicationis provided by an electro-optical cable allowing unique colour point-to-point communication between eachDOM and the shore station readout system. Each mechanical supporting structure consists of twenty 6 m long barswith a DOM at each end. The bars have a vertical separation of 40 m giving the full structure a height of around 900m. The foreseen budget allows for construction of about 300 of such structural units. Together they will create an in-strumentedvolume of between 5 and 8 km3. The sensitivity to point sources near the Galactic centre surpasses that ofany other telescope by two orders of magnitude.
