We've just had sale agreed on a fab house. The kitchen is beautiful, navy units with white granite worktops, island in the middle (with the sink) . It's doesn't have an overhang on the worktop though for seating, which my current house does and we use it for eating every day (never use our table). Is there anyway to make an overhang, even with a different contrasting material so that we don't have to replace the whole granite worktop? Thanks
