Tasmania Cold Climate Building Requirements and Hobart Heritage Controls
Tasmania's cold climate means new homes must meet higher insulation standards than many mainland states, minimum ceiling, wall, and floor insulation R-values for the Hobart climate zone are substantially higher than for Brisbane or Perth. Double-glazed windows are increasingly common in Tasmanian new homes to maintain warmth in sub-zero winter conditions. Hobart's heritage precincts (Battery Point, South Hobart, New Town) have strict controls on building form and materials, new builds in these areas must be carefully designed to be sympathetic to the established streetscape character. cbos.tas.gov.au
