Construction times in the capital have doubled in just over a decade, deterring people from building in the territory.
Data from Master Builders Australia has revealed the median time to build a freestanding home in the past year was 14 months, up from 7.5 months in 2010.
The figures had been trending consistently upward in that time. Townhouse construction times hit a peak of 19 months last year, but were now back to 13 - still five months longer than in 2010.
