We summarise some common interior balustrades and exterior balustrade handrails fixings with charts
Many Councils are now asking for the fixing details of the handrails and infills to the balustrade posts as these are specific engineering design details.
We summarise some common interior balustrades and exterior balustrade fixings below along with helpful charts.
Here are three typical internal balustrade fixings that require Engineering Certification:
External decks in NZ are popular. In terms of use, decks include waterproofed decks and timber-slatted decks (“through” decks).
External balustrades include balustrades for decks, balconies and swimming pools.
Proconsult has been active in ensuring compliant changes to the deck edge fixing details. Lumberlok have amended their details for compliance with the Building Code and these new details and balustrade spacings apply since December 2018.
Note that spacings for balustrades have closed up and that the balustrade fixing system is reliant on an independent support structure, or bearer, to support the joists.
Proconsult has been engaged with many deck and balustrade designs throughout the country. Please contact us today to discuss your requirements.

A Code of Compliance is essential to assure you and future owners that the Building Code requirements have been met. So, how long should the process take, and what can you do to speed it up?
Insulation requirements changed significantly on 1 May 2023 for residential houses in Aotearoa NZ. The new requirements are all covered by H1 (Energy Efficiency) in the New Zealand Building Code (the Code).
Where does the buck stop? As engineers, we want liability to be designed out of the build, but time and cost can sometimes sway clients, builders and homeowners to look for cheaper alternatives.
Engineering fees for small projects are usually charged on the number of hours the structural engineer works on your project. The costs will be individual to your project.
Has your house been damaged in an earthquake, landslide or water ingress? Or has your house been repaired or altered, but you believe the repairs may not have been done properly? Perhaps you just want a second opinion for peace of mind or insurance purposes.
Do you have a student who wants to become a Structural engineer?
Here are a few thoughts on how to guide them, what to expect, how to get a taste, and which universities to consider (in NZ and further afield)
