MORE than 15,000 Blockheads are expected to descend on St Kilda this Sunday to get a sneak peak of the notorious Gatwick Hotel’s transformation.

The once grimy property with a grisly past has been converted into high-end apartments on Channel 9 reno show The Block.

Fans hoping to inspect the final product can visit the site at 34 Fitzroy St from 10am to 2pm on October 7.
