AFL superstar Dustin Martin and his manager Ralph Carr have extended their spending spree in Melbourne’s inner east, after purchasing a fourth commercial building on Butler Street in Richmond.

The three-time Richmond Tigers premiership player and Mr Carr, whose firm Ralph Carr Management has its office on Lennox Street in Richmond, now own a row of warehouse-style buildings with a combined footprint of nearly 900 square metres running from 23 Butler Street to 37 Butler Street.
