SR412 Medium-density housing construction quality survey (November 2018)
Product Description
Medium-density housing (MDH) has been suggested as a solution to affordability and land availability issues in New Zealand. As New Zealand shifts away from stand-alone housing towards increased MDH developments, it is important to understand and overcome potential quality issues.
Problem areas that we found as part of this study included weathertightness risks, roof bracing, provisions for services and a lack of common design detailing for MDH. Many of these issues are shared with stand-alone housing. However, the risk of failure is potentially higher in MDH, as the construction is generally taller and utilises multiple claddings with complex wall junctions and narrow eaves.
This study also looks into learnings from the existing stock of MDH, particularly around the need for maintenance. We propose utilising cladding materials that have low life cycle costs, which are typically those with lower maintenance requirements.
