The challenge

Keep the character, lose the cold draughts

Renovating a character villa is always a balancing act. Homeowners want to preserve the charm and architectural details that make these homes special, while also improving comfort, warmth and day-to-day functionality.

As part of a complete renovation and new extension across the entire back of the house, these homeowners needed windows and doors that would suit the style of their villa without compromising on modern-day expectations for comfort and energy efficiency.

Finding the right product was important, but so was finding a supplier who could provide confidence throughout the design and build process.

The homeowners took their time researching options and visiting suppliers before discovering NK Windows.

Unlike many suppliers from outside Christchurch, NK Windows offered the advantage of a local showroom, factory and knowledgeable support team, allowing the homeowners to see, touch and operate the products before making their decision.

Original leadlight features retained and enhanced with new window systems with Tilt & Turn opening.

The solution

Light-filled, warm and dry – “Actually, a pretty seamless experience”

After selecting NK Windows, the project moved smoothly from specification through to installation.

The NK team worked closely alongside the homeowners, architect and builder, ensuring the window package integrated smoothly into the wider renovation programme.

As they are local, we could go into their office and sort anything we needed. To see and operate the windows and doors was a big plus over product providers from out of town and who were often unresponsive.

The combination of local expertise, manufacturing, installation and support all based in Christchurch helped the project run efficiently and without unnecessary complications.

Working with NK Windows also made the process straightforward, even alongside EQC repairs. The team worked around EQC repairs and even completed the job in two parts.

The installation process felt seamless for the owners, with the team described as slick, tidy and efficient.

The result

Noticeably warmer, quieter, drier and more comfortable

The transformation has been significant. Today, the renovated villa is noticeably warmer, quieter and drier, creating a more comfortable living environment year-round while maintaining the home’s traditional character.

One of the most noticeable improvements has been the complete elimination of condensation, a common problem in many older homes and even some modern aluminium joinery systems.

Looking back on the project, the homeowners say the quality of the product stands out above all else.

It is a quality product. Compared to aluminium frames, they look much better and have 0% condensation. Plus different opening and closing options.

The flexibility of the NK Windows system also allowed the builder to achieve a finish that remained sympathetic to the villa’s original style.

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

Original leadlight features retained and enhanced with new window systems with Tilt & Turn opening.

"It is very quiet, warm and dry in the house. The windows look great."
