Townhouse Floor Design Guide

Townhouse construction demands smarter design decisions - especially when it comes to fire separation, acoustics, compliance, and making the most of every millimetre.

To support builders and designers in this space, we’ve developed the Wesbeam Townhouse Floor Design Guide - a practical, easy-to-use resource created by our Design and Engineering Team to help you deliver compliant, efficient, and sustainable townhouse floor systems.

Inside the guide, you’ll find:

• Clear guidance on NCC Class 1 a requirements
• Proven e-joist detailing at separating walls
• Span tables and service hole guidelines
• Design strategies for narrow lots and repeatable builds

General: How to handle and store your Wesbeam Laminated Veneer Lumber e-joists.

1. Timber joists must only be stacked in the upright position to avoid any damage during storage or handling
2. Only stack on level bearers (3.0m spacing max) providing a ground clearance of at least 150mm
3. Do not stack e-joists on the flat
4. Cover e-joist to keep dry while allowing for ventilation
5. Avoid placing e-joist over areas susceptible to ponding.
