The most popular style of home unit buildings is the so-called 3 storey walk-up units. Pictured is one of such buildings constructed by Chiha Developments in the Sydney suburb of Dee Why.

An underground parking area had to be accommodated partly in sand and partly in rock. Columns and walls were bearing directly on rock or were piered to rock. Whilst minimum construction depth was desirable, beams over the carparking area had to span over 7.0 metre wide driveways and deflections had to be minimised to reduce long term brickwork cracking in the suspended walls.

The building was also split into 2 levels to adjust its height to the residual slopes of the land. The photomontage of the building shows how a pleasant structure was achieved with large balconies supported on slender round concrete columns. The developer was apparently very happy with the result both in financial as well as aesthetic outcomes. This was one of more than 15 similar buildings which Kneebone & Beretta Consulting Engineers Pty Ltd designed for Chiha Developments.
