Client: Cala Homes
Installer: Dalziel
Location: Killearn, Scotland
Sector: Multi-unit Residential / Developer Project

Brief

Dalziel engaged Origin Commercial to supply bifold doors for a cluster of premium apartment units in their latest development. The client was keen to offer a high-end visual aesthetic to stand out in the market, but also had stringent requirements around lead times, compliance, product warranty, and after-sales service. A key aesthetic request was for dual-coloured bifold doors: white internally to match modern interiors, anthracite externally to present a sleek, contemporary street look.

Origin Commercial Solution & USPs Delivered

  • Custom dual-colour aluminium bifold doors: Origin supplied bifolds with anthracite finish externally and white internally, leveraging the Origin powder-coating facility and wide palette (over 150 colours). This dual-colour finish ensured consistency with external branding while maintaining bright, clean interiors.
  • Secured by Design & compliance: All doors complied with building and security regulations, including Secured by Design accreditation, helping the developer meet both specification requirements and buyer expectations.
  • Rapid lead times & project reliability: Given Origin’s control over the entire manufacturing process from design through delivery from the High Wycombe factory, the lead times were tightly managed. For popular colours, turnaround was significantly faster, helping avoid delays.
  • Full 360° service: From concept, through tender and delivery, Origin worked closely with architects, installers, and project managers to ensure measurements, hardware choice, thresholds, and installation methods aligned with site constraints. Any potential risks identified early and were addressed in pre-installation reviews.
  • Warranty & aftercare: Doors came with the industry-leading guarantee, enabling the developer to market long-term durability and reduce buyer risk.

Outcome & Business Impact

  • The anthracite/white bifolds created a strong visual differentiation in the development’s marketing material, enhancing perceived value.
  • Interiors benefitted from increased natural light and a brighter atmosphere, which according to post-handover surveys improved buyer satisfaction.
  • No delays on critical path: early engagement, modular manufacturing, and Origin’s reliable lead times allowed project timelines to stay on schedule.
  • Reduced after-sales issues: thanks to quality manufacturing, tight sealing, and secured hardware, after-installation snagging was minimal, reducing warranty calls and maintenance cost exposure for the developer.
  • Enhanced commercial reputation: the successful use of dual-colour bifolds with strong performance credentials reinforced the developer’s brand as quality-led.
