Future-Focused Timber Engineering in the Heart of Nelson

At 51–55 Bridge Street, a new benchmark in sustainable urban development is complete. This commercial building, designed for Tinline Property, is a showcase of mass timber construction, resilient seismic design, and agile delivery — all within a tight design and construction timeframe.

Engineered by Structex and designed by Irving Smith Architects, the structure features a hybrid system of CLT floors, LVL beams and columns, and precast concrete shear walls, delivering both architectural warmth and structural performance. The use of engineered timber not only reduces embodied carbon but also enhances construction efficiency and seismic resilience.

Key innovations include:

• LVL timber structural elements locally sourced from nearby Nelson Pine.

• Seismic design exceeding code minimums, anticipating future hazard model updates.

• Suspended ground floor slab to manage contaminated soils and high water table.

• Prefabricated elements and early contractor involvement to streamline construction sequencing.

The building is part of Nelson’s “Bridge to Better” initiative, aligning with the city’s vision for a vibrant, pedestrian-friendly future. With a mix of tenancies and a structure designed for longevity, adaptability, and low environmental impact, this project is a model for future-ready commercial development in New Zealand.
