Saint Marys Bay Clifftop House

We were engaged to prepare the structural design and detailing of a new high end 3 storey clifftop house in a prominent location in Saint Marys Bay.

This was a very complex site, which required careful consideration of geotechnical requirements, construction sequencing and protection of neighbouring properties for a successful outcome.

Significant retaining walls were required to protect the site and ensure stability given the site is bounded on two sides by cliffs on the original waterfront prior to the motorway land being reclaimed in the late 1950s. Approximately 200 cubic metres of concrete were poured to form the site retaining walls, barrier pile walls and swimming pool before the house foundations were even begun.

The swimming pool is entirely pile supported, and spans over an existing 1200 diameter brick stormwater drain that is approximately 100 years old. During the design phase we identified an opportunity to combine the barrier pile wall with the swimming pool. Working closely with the geotechnical engineers and architect, we were able to come up with a design that saved the client approximately $40,000 worth of site retaining.

Further cost savings were made by working with the architect to alter the lower level floor layout which saved an estimated $110,000 in retaining works while achieving an end result that the client and architect were satisfied with.
