URBAN DENSITY & BUILDING HEIGHT

Since this blog began we have been attempting to point out the disconnect between building height and development density.

Our qualitative assessment of two inner urban areas of Brisbane (Newstead & Petrie Bight) showed the diametrically opposed urban form characteristics of each area (podium/tower high-rise type vs. low-rise perimeter block form) and offered some value judgements on the relative merits of each type in terms of the actual environment created for residents.

See our post of 13 May 2010  – 

…Inner city Brisbane – a few comments on density & height… https://neylanarchitecture.wordpress.com/2010/05/13/

and our further post of 27 July 2010  – 

 … Brisbane urban renewal – higher density or higher views…  https://neylanarchitecture.wordpress.com/2010/07/27/

Since then we have discovered a useful reinforcement of our judgement in a recent study which provides a quantitative assessment of  ten world cities undertaken to inform a Structure Plan being prepared for Southbank (Melbourne). Key outcomes include :

  • HIGHER BUILDINGS DO NOT DELIVER HIGHER DENSITIES THAN MID-RISE BUILDINGS (up to 12 floors)
  • QUALITY OF STREET INTERFACE HAS A DIRECT RELATIONSHIP WITH BUILDING HEIGHT AND TYPOLOGY

Go to this link to view the complete document which uses a comprehensive set of metrics to arrive at some interesting conclusions.

Here is a one page summary of the report.
