Trial Bay House

Trial Bay House by HBV Architects won the Robin Boyd Award for Residential Architecture – Houses at the AIA's 2010 National Architecture Awards.

An exceptional house may be one with such calmness and serenity that it is hard to leave. The remodelling and additions to the Trial Bay House have created such a house.

Two existing pavilions have been extensively remodelled and two new pavilions added, with enclosed linking passages.

The dominant new pavilion is strongly geometrical and robustly constructed of angled precast concrete walls, roofs and window sills, forming shutter-like apertures to the view. The view is further enhanced by the quality of light reflected off these shaped concrete reveals. Concrete was selected for its strength and durability, and despite the rigid, strong form succeeds in producing a structure of surprising softness and delicacy.

New windows and door openings have been added to the existing central pavilion, connecting house to landscape. It is not surprising that the immaculate and original details are the result of the architect carefully preparing reams of full-size drawings. The links between the pavilions are similarly carefully detailed, contributing to an ordered sense of calm.

The new pavilion is positioned to capture winter sun and the rebuilt old pergolas act as glazed greenhouses to naturally heat the existing pavilions.

There is a sense of striking originality yet extreme serenity in this understated house.
