Home’s new lease on life
APROJECT that maximised the potential of a 1920s home won the residential architecture houses, alterations and additions category at last night’s Tasmanian Architecture Awards.
The addition to the rear of this Browne St property, in West Hobart, was designed by Preston Lane Architects.
PLA director Daniel Lane said the project was defined by three key design gestures: the establishment of the new podium to the rear, crafting of a new “floating’’ roof and the sleeving of the new into the old through the relocation of the heart of the home to the rear of the property.
“The podium provides a new datum for the rear of the site grounding the extension and elevating the previously steep backyard to the level of the addition,’’ Mr Lane said.
“Workshop space was located within the sub-terranian area, its structural concrete cell providing a cost effective retaining solution.
“The result was a usable viewing platform to the panoramic views across Hobart.’’
Mr Lane said a project of this type explores the benefi ts of reusing and reviving an existing ‘ 20s home.
“The extension injected new life into a potentially under- utilised inner city block,’’ he said.
“A socially sustainable response, it has allowed the growing family to stay in their existing house rather than moving out of the city into a larger suburban block.’’
Passive- solar tactics were integral to the planning and layout of the extension.
Mr Lane said double- glazed windows had been used throughout with carefully located openings to provide cross- ventilation through the building extension.
“The roof form allows for the northern sun to penetrate deep into the building during the winter months, while controlling the sun during the summer time,’’ he said.
“External walls and the roofi ng have been insulated heavily throughout, and the concrete fl oor slab has been insulated, to provide more stability within the thermal mass of the product.
“Control methods upon the heating of this slab, assist with providing an even base temperature for the building.’’ Results of the Tasmanian Architecture Awards People’s Choice awards will be published in next week’s edition of the Sunday magazine
