This incredible north facing multi-level home is on the Brisbane River and has majestic views across to Teneriffe and the city skyline.
Designed by award winning Architect Angus Munro, the home offers incredibly large open plan living areas, a separate pool house and private front courtyard and tennis court.
Challenge
We were faced with multiple challenges on this project, some of which occur below ground and some above ground. Results from the geotechnical investigation showed a rock layer that ran across the site, protruding in one corner of the property and then dipping to almost 18m in the opposite corner. This would create substantial issues with the foundation design.
Above ground, our client requested large, opulent, open areas but insisted that the construction be a steel & timber frame, usually used on more conventional residential projects, as well as requesting zero ‘bounce’ in the floor structure and a solid feel under foot.
Solutions
The foundation design utilised multiple pier options including shallow backhoe piers, intermediate concrete filled bored piers and much deeper steel screw piers – all of which penetrated poor soil layers at the surface and were eventually founded down into rock. This design proved challenging for both us and the skilled contractors onsite during construction, but the end result was successfully achieved.
The large open plan areas were realised using a combination for structural steel beams, laminated engineered timber joists as well as a lightweight concrete panel flooring system that gave an end result of that concrete feel, with no bounce in a much lighter weight construction.
The challenges onsite getting up out of the ground were endless but the NGS team were able to adapt their design to suit while providing a fast, cost effective design.
