The challenge

Noise, Maintenance & Interrupted Views

The existing timber joinery was a burden for the owners from the moment they bought the property. With two young children, the family wanted a home that would be quieter, warmer and easier to maintain.

There was considerable road noise through the existing windows, along with draughts and gaps. The old wooden frames also required regular maintenance and were beginning to deteriorate.

In addition, the older window designs contained cross frames that interrupted what should have been expansive views across the valley.

After: uPVC doors create seamless indoor-outdoor flow and open up stunning valley views.

The solution

A holiday from maintenance with stylish NK Windows uPVC Double Glazing

The couple chose NK Windows uPVC double glazing to modernise the home while enhancing its connection to the outdoors.

Key benefits of the solution included:

  • Cleaner window designs that removed visual barriers and opened up the views
  • Double glazing for noise reduction and thermal performance
  • Low-maintenance uPVC frames, ideal for long-term durability
  • Locally made products backed by a highly experienced Christchurch team

The new configuration replaced the original cross-framed glazing with cleaner, larger expanses of glass. This created a stronger indoor-outdoor connection and allowed the home’s elevated position and valley outlook to become a defining feature.

The result

A Warmer, Quieter, More Connected Home

The transformation has been immediate, improving both comfort and the overall feel of the home.

  • Significantly reduced road noise
  • A warmer home in winter with improved insulation
  • The ability to leave windows ajar for ventilation with confidence
  • Uninterrupted views that fully capture the surrounding landscape
  • A greater feeling of security and cosiness

Inside, the home now feels calm, modern and light-filled. Clean white window frames contrast with the darker interior tones, while large expanses of glass bring the outdoors in.

A standout feature is a simple armchair positioned beside a large picture window — now the homeowner’s favourite place to sit.

After: uPVC doors create seamless indoor-outdoor flow and open up stunning valley views.

"So much warmer, the noise is much less… and the view — an uninterrupted landscape."
