The client
William Earp Place in Tawa, Wellington.
Developers approached UNO Windows & Doors along with Designgroup Stapleton Elliot and Stackhouse & Firth to provide an effective solution for a brand new 25-townhouse development in Tawa, Wellington.
Going beyond the provision of 163 window & doors, UNO's expert design and spec team used unique in-house software to uncover efficiencies totalling approximately $20,000 to $25,000 worth of savings for the client through innovative configurations to the product design.
Success stories like these are exactly the reason why UNO is the supplier of choice for a growing number of architects and developers who value end-to-end solutions that save on time and money for multi-residential projects.
Scope
An Opportunity to Value Engineer
As costs were slowly rising for the project, finding efficiencies was paramount in ensuring that the development would be delivered while still meeting H1 thermal compliant building standards.
Challenges:
- Rising Project Costs: The developer needed a value-engineered solution to bring the project back within budget while still achieving compliance.
- Detail & Specification Support: Early design stage and specification support to provide adaptable solutions for the project regarding H1 construction R-values.
- Adaptable Solutions: Being able to reconfigure the product design in order to meet the client's desired outcome.
Our collaboration with Designgroup Stapleton Elliot proved critical, as UNO was able to work closely to uncover exciting solutions to solve this challenge.

Solution
Eureka: A Different Path to Thermal Compliance
The UNO team worked closely with the architect to re-evaluate the compliance pathway, modelling the specific construction R-value of the product and incorporating it into the overall calculation. By considering the townhouse design, window and door configurations, glazing make-up, and UNO profile performance, we demonstrated that:
-
UNO Non-Thermal Suite + Low-E Lightbridge Double Glazing could achieve full H1 compliance.
-
Compliance was achieved while reducing overall joinery costs by 8–10% — saving approximately $20,000 to $25,000 across the development.
- This resulted in the delivery of 163 compliant windows & doors designed to meet the client's cost targets.
Adaptable Delivery Solutions
UNO provides adaptable shipping solutions to deliver our units anywhere in New Zealand for multi-residential purchase orders. Our methods ensure timely and efficient installation nationwide.
Key Outcomes:
- Seamless delivery of 163 aluminium window and door units for the development's 25 townhouses.
- Precise thermal compliance and energy efficiency achieved with the UNO Non-Thermal Suite and Low E Lightbridge Double Glazed glass.
- Value-engineered an optimal H1configuration during the planning stage to uncover approximately $25,000 in joinery cost savings, or 8-10%.
At UNO our commitment to delivering value with every project goes beyond just the supply of quality aluminium joinery. Our full-package solutions ensure that clients are always presented in the most optimal product crafted by our expert team.
