This remarkable project by HR Constructions involved the transformation of an existing double storey home in a prime Sydney location, into a much larger four storey home, not by adding floors above as one might expect but by adding two lower levels, requiring extensive excavation of the rock foundations and propping up of the existing residence so that the additional floors could be added, and existing floors extended and modernised.


Construction was completed using large, suspended concrete slabs and masonry walling. Of course, working with an existing home insitu created several difficulties, including space restraints that required the HR team to cut out the existing slab with a remote controlled concrete saw. The resulting home however is a stunning, luxury residence which incorporates over 672sqm of floor space and offers breathtaking views over Balmoral Beach, Middle Harbour and The Heads from all four levels.

Two lifts service the home as well as this stunning off-form concrete, spiral staircase.



From the street, the front façade makes it quite clear that this home is unique. A contemporary profile with extensive timber cladding that is continued on the garage and entry door – so that they are almost hidden from view like secret entries, combines with free form stone work which softens the angular lines.

The owners wanted a quality home with detail and the finishes throughout the home include feature timber, herringbone laid travertine, and extensive stonework, including a 6 meter high wall in the dining room which has been created by an upper floor void. There are also flush shadow lines to all walls, ceilings and doors and a stunning staircase with feature timber treads that cantilever out of a stone clad wall. Throughout, HR Construction’s quality craftsmanship and meticulous attention to detail that was noted by the MBA judges is clearly evident, particularly where the stonework and other materials join.

Extensive glazing at the rear of the home has created a connection between interior and exterior living spaces
