Stonehawk by Base Architecture.A challenging project to secure Queensland’s Old Government House for generations without detracting from its past has been awarded top honours in the Australian Institute of Architects’ 2010 Brisbane Regional Architecture Awards.

The project - Old Government House Conservation and Adaptation by Conrad Gargett Architects - was awarded the 2010 John Dalton Award for Building of the Year.

Queensland state awards director, Bud Brannigan, says: "The designers have successfully provided a considered and sensitive response to a project that was not without considerable challenges, and the refurbishment allows the public to use and enjoy this building for many years to come, while not destroying or detracting from any of its historical importance and ambience. It is a superb example of how an historic building can be restored and revitalised for the benefit of the wider community as a whole."

All up, 133 architectural projects were entered in this year’s Brisbane regional awards, with a total of 35 regional commendations awarded.

The jury presented the House of the Year Award to Stonehawk by base architecture. Brannigan says the project was "an exceptional solution to an everyday problem.

"This single family house on a west facing steep suburban site is a close fit but flexible house for a young family. Against the trend, this house embraces multiple use rather than multiplicity of space within a considered architectural framework which deals with the programme, the orientation and the environment."

Thirty-three other commendations were also presented, including:
