The major component of dwelling unit approvals is new houses (table 19.7). New house approvals accounted for 67% of total dwelling unit approvals in 2004-05, up from 66% in 2003-04. New houses and new other residential dwelling units experienced a decrease in the number of approvals in 2004-05, of 11% and 14% respectively, compared with 2003-04, while the number of conversion approvals increased by 10%. Overall, total dwelling units approved decreased by 13% compared with 2003-04.
NEW OTHER RESIDENTIAL BUILDING APPROVALS
Other residential building refers to structures other than houses, which are built for accommodation purposes. This includes buildings such as blocks of flats, units and apartments, and semi-detached houses and townhouses.
Prior to 1996-97 approvals for semi-detached houses, row or terrace houses and townhouses were greater than for flats, units and apartments. From 1996-97 the number of approvals for flats, units and apartments has consistently exceeded approvals for semi-detached houses, row or terrace houses and townhouses.
While they are still the major component of new other residential approvals (contributing 55% of all approvals), in 2004-05 the number of approvals for flats, units and apartments decreased. Since 2002-03 the gap between the two dwelling types has converged, with approvals for semi-detached houses, row or terrace houses and townhouses decreasing at a much slower rate than approvals for flats, units and apartments in 2004-05 (graph 19.8).
Table 19.9 provides additional details of the types of other residential dwelling units approved. In 2004-05 new semi-detached, row or terrace houses and townhouses showed decreases in both one storey (1%) and two or more storeys (7%) approvals. All types of new flats, units or apartments building approvals decreased in 2004-05 compared with 2003-04, with four or more storeys decreasing the most (24%). Approvals for new flats, units or apartments with four storeys or more, accounted for 38% of new other residential building approvals in 2004-05, down from 43% in 2003-04.
NEW RESIDENTIAL BUILDING WORK DONE
Between 2003-04 and 2004-05 the value of total building work done (in chain volume terms) increased by $397m (less than 1%) to $53,970m (table 19.10). However, total new residential building decreased by $321m (1%), with new residential building for houses decreasing by $304m.
During 2004-05 new residential buildings generated 56% of the value of total building work done (in chain volume terms). A further 33% of the value was generated by non-residential building, while alterations and additions accounted for the remaining 10%. Estimates of alterations and additions to residential buildings include all approved building activity carried out on existing residential buildings, valued at $10,000 or more.
