Around 160,000 bees now call West End home, with the yellow buzzing insects housed on a building rooftop.

Bee One Third founder Jack Stone installed four beehives on the top of the Westpac Bank building on Boundary Street.

The bees are part of a "green installation" at the $1 billion West Village development.

When complete, the 2.6-hectare West Village will include eight apartment buildings and about 13,000 square metres of retail and commercial space all linked by pedestrian and cycle laneways.
