ViaStrada secure bike parking

One of the car parks in the basement now caters for ViaStrada staff bikes. There's room for a whopping 12 bikes - we reckon that's a very good use of that space. But given the rate at which we are growing, and the high proportion of our staff who bike to work (three quarters of staff in the Christchurch office), how long will it be before we run out of space and have to convert another car space for bikes?
