As the debate over intensification versus urban sprawl seemingly intensifies, there is one assumption that seems to underpin a lot of the discussion – from both sides of the debate actually. That assumption is that achieving most of Auckland’s future growth through intensification will be an enormous challenge, a ‘step change’ from what Auckland has done before, requiring a huge change in mindset away from living in a traditional (mythical) “quarter acre paradise” and towards living in different housing typologies like terraced housing and apartments.
The Auckland Plan’s development strategy – which generally (at least in words) supports a compact city approach – runs this “story” quite significantly:
Over time, the viability of attached and higher-density housing will improve, and provide choice for Aucklanders. Chapter 10: Urban Auckland shows examples of housing types across a wide range of densities and formats, and indicates the types of locations where we can expect them to be built. This is also explained in the following section on the Development Strategy maps. A healthy supply of high-density housing has the potential to address the challenge of housing affordability, through efficiencies in land use and infrastructure provision. The delivery of housing choices depends on many organisations, notably the private sector.
While it’s true that detached housing has typically constituted the majority of dwellings built, this doesn’t mean that Auckland’s recent growth has predominantly been through urban expansion – therefore making a “70/30 split” between intensification and expansion supposedly aspirational. Well some information we have managed to obtain from the councils research unit shows that when you look at the proportion of housing comprising either ‘intensification’ (additional dwellings within the existing urban footprint) or ‘expansion’ (additional dwellings outside the existing urban footprint) over the past 15 years a significant majority of new dwellings are ‘intensification’:
Looking at the numbers in terms of proportions it’s clear that in every single year many more dwellings have been consented inside the current urban area than outside – with 2005 being the year with the lowest proportion of intensification at 61%:
While of course many of the ‘easier’ intensification opportunities, such as infill housing, have been used up over this time (and the decades before it – Auckland has been significantly intensifying since the 1970s), what this information clearly shows is that achieving most growth through intensification is not really a challenge. We’ve been doing it quite well for quite some time. Clearly Aucklanders seem to have preferred the choice of living somewhere within the existing urban area – even if it meant a smaller section or an apartment or some other form of housing – than the urban edge.
Given this background, the Auckland Plan aspiration of 70% of development being within the 2010 urban limits (which actually go significantly beyond the 2010 urbanised area) seems nothing but business as usual and anything below that is actually a shift away from what Auckland has been doing for the past 15 years towards a greater focus on urban expansion. A focus on most growth through intensification is not revolutionary or aspirational or ‘requiring a step-change’ at all – it’s what we’ve been doing for quite a long time.
