NSW builder Roberts will expand into residential construction – a sector it has avoided over the first eight years of its life – and widen the scope of projects it is willing to take on under the financial backing of new owner Arada, chief executive Emma Shipley said.

The Roberts Co NSW business, which since its founding by Rich List owner Andrew Roberts in 2017 has focused on commercial construction and government and steered clear of apartments, would also consider projects worth less than the $200 million limit it previously set, she said.
