Structural timber is experiencing a revival, re-emerging as a material of choice in contemporary architecture due to its performance, versatility, and natural aesthetic. 

In New Zealand and around the world, engineered timber products like glulam are enabling stronger, smarter and more design-driven structures. From homes and schools to large-scale commercial projects, designers are using structural timber across interior and exterior applications to create spaces that are more open, efficient, beautiful and built to last. 

Why structural timber is a standout choice

Whether it’s hidden in the frame or celebrated as a hero design feature, structural timber is bringing form and function together like never before.

1. Strength and versatility

Engineered timber products like glulam beams, posts, trusses and portals offer exceptional strength-to-weight ratios and dimensional stability, enabling wider spans and higher load bearing capacity. This added structural performance is expanding timber’s role in larger, more complex buildings – increasingly replacing steel and concrete in key applications. 

Just as importantly, structural timber offers design versatility. It suits a wide range of uses – indoors and out, exposed or concealed – making it ideal for everything from architectural interiors to alfresco areas and architectural facades. 

2. Aesthetic appeal

When used as exposed timber features, glulam beams, posts and trusses add natural warmth and visual interest to interiors and outdoor spaces. Timber also aligns beautifully with biophilic design principles – connecting people to nature while supporting wellbeing and enhancing the sensory experience of a space.

3. Sustainable, low-carbon construction

Timber is renewable, biodegradable, and stores carbon for the life of the building. Compared to steel and concrete, it requires far less energy to produce and can be sourced from sustainably managed forests – such as the New Zealand plantation-grown Radiata Pine used in Prolam glulam products. 

Applications of structural timber in contemporary architecture

Structural timber is central to many of today’s leading architectural trends – from open plan living to natural material palettes, sustainable building methods, and stunning structural forms. 

Here, we explore some of the most popular and high-impact ways structural timber is being used in New Zealand architecture today – supported by Prolam engineered timber solutions.

Elevating interior spaces with exposed timber features

Exposed beams, trusses and posts bring structure into the spotlight – adding depth and character to interior spaces. Timber’s natural aesthetic softens hard lines and connects occupants to nature, while glulam’s engineered performance ensures long spans and robust structural support. 

Prolam’s visual grade glulam is precision-machined for a flawless finish, and can be clear-coated, stained, or painted to suit architectural intent – from rustic to refined.

Creating all-weather alfresco areas with structural timber

With the growing emphasis on outdoor living and seamless indoor-outdoor design, structural timber is a natural fit. 

Engineered for strength, straightness and stability, and treated for lasting protection against moisture and insects, Prolam products maintain their structural integrity in exposed outdoor settings. This makes them ideal for alfresco areas, pergolas and decks.

Making a statement with timber facades and entry features

Architectural facades and entry zones are the face of a building – and timber makes a lasting first impression. From verandas and porticos to bold timber-clad entryways, structural timber elements like glulam beams, posts and trusses offer a timeless, tactile finish that complements both traditional and contemporary architectural styles.

Supporting open plan design with timber beams and bracing

Long-span glulam beams and hybrid timber-steel solutions are enabling greater openness in homes and buildings – reducing the need for internal walls and supports.

Prolam’s innovative bracing systems – the PLX Portal and PLX Column – are engineered to deliver high-strength bracing in a compact footprint. This enables architects and engineers to maximise openings and living spaces with greater efficiency and confidence.

Building bigger with timber: commercial and community structures

Innovations in engineered timber are unlocking new potential for larger, more complex builds. From retail spaces to industrial facilities, sports centres to education hubs, glulam is being embraced for its construction speed, reduced environmental footprint, and architectural flexibility.

Prolam’s structural and visual grade glulam products are designed to meet the performance and compliance needs of commercial projects – delivering strength, durability, and standout aesthetic appeal.
