In the search for efficient, cost-effective intertenancy wall solutions, a game-changing breakthrough has emerged in medium-density housing construction. While concrete has always been an obvious choice for intertenancy walls, traditional methods have faced limitations due to the high costs associated with bulky formwork and other labor-intensive concrete wall systems. But a new innovation in concrete use, led by Stackcell Structures, promises to overcome these barriers, offering a solution that’s faster, cheaper, and highly effective.

Concrete is renowned for its durability, fire resistance, and sound insulation. However, traditional concrete systems for intertenancy walls have required costly, large formwork setups or alternative concrete wall systems that, although quicker to install, are often prohibitively expensive. While these alternative systems might claim double the speed, their costs often outweigh the benefits, especially in projects where construction inefficiencies in other areas lead to slower timelines overall.

This is where Stackcell Structures steps in. Their innovative approach rethinks the way concrete is used for intertenancy walls. Stackcell’s system doesn’t rely on a single costly component but instead integrates a full structural solution, incorporating efficiency measures that make it comparable in cost to traditional timber walls. In fact, when accounting for all aspects like structural integrity, installation time, material cost, acoustic performance, and fire resistance, Stackcell's concrete solution can even prove to be cheaper.

Stackcell’s system is more than just a concrete wall—it’s an entire structural solution. Their design reimagines how concrete is poured, leveraging molds that simplify and streamline the process, significantly reducing construction costs. By eliminating the need for bulky formwork and streamlining the construction process, Stackcell’s technology slashes the overall expenses of concrete intertenancy walls. Behind the plasterboard of a Stackcell wall, you’ll find a solid concrete core, delivering all the benefits of a high-quality intertenancy wall at a fraction of the traditional price.

The result? A solid concrete wall with the structural integrity, acoustic performance, and fire resistance that builders have long sought in intertenancy walls. Yet, unlike older systems, it offers an unprecedented alignment of quality, speed, and cost-effectiveness, meeting all three priorities without compromise.

While developed for New Zealand’s unique housing needs,and seismic resilience, Stackcell's system has potential applications worldwide. As urban areas continue to grow and the demand for medium-density housing rises globally, solutions like Stackcell’s could redefine construction standards, setting a new benchmark for cost, speed, and quality in Medium density housing. Having completed 750 apartments in Auckland already, the proof is in the pudding!

​The use of concrete in intertenancy walls has long been "right under our noses," yet the key to unlocking its potential lay in rethinking how it’s implemented. With Stackcell's breakthrough, concrete is now a viable, competitive option for builders everywhere, aligning affordability, quality, and efficiency in a way that’s set to transform housing projects not only in New Zealand but around the world.
