Historic Red House Renovation Features Kingspan Kooltherm Insulation

The Red House is a category one historical building, that has become an architectural icon in Christchurch. The house was recently featured on series four of Grand Designs New Zealand, thanks to the alterations made by couple Johannes van Kan and Jo Grams.

The van Kan family purchased the property in 2013, following the loss of their iconic apartment located in the Lyttelton Council Chambers Building in centre of historic Lyttelton, on Banks Peninsula, in the 2011 Christchurch earthquake. What commenced can only be described as a labour of love as the couple restored the historic Red House building and added a contemporary extension of the building, designed to maximise the views over Cranmer Square.

Refurbishing a historic building with such an extensive architectural history proved to be a challenge and a number of design revisions were made before the final plans were cemented and council approval was obtained. “We wanted the exterior to be simple and possibly mysterious, much like the street facade of the original Red House that we are attached to. We wanted the good stuff to be on the inside”, commented Johannes van Kan. The iconic red paint was kept on the original building and its new interior is dark and detailed with light and sound to bring about a wonderfully mysterious and luxurious feeling to the home.

The interior design features refurbished materials used from the couple’s original home in Lyttelton and focuses on alternative design and obscure difference, and adds to the unique and extensive architectural history the building has accumulated. “A home is a blend of the individuality of people, the creativity of architects, the solutions of engineers, the cunning of builders, and the physicality of the materials”, commented Johannes van Kan.

Kingspan’s Kooltherm high-performance rigid board insulation was installed into the skillion roof and all external walls, allowing for a thin profile without the compromise of poor energy performance, and allowing for a more contemporary design. “The incorporation of Kingspan into our build is a smart variation on the New Zealand domestic standard fluffy solutions to insulation," says van Kan. "We have large open spaces where the heat could potentially escape, so it was important to minimise our losses with an effective insulation solution”.

Kingspan Kooltherm was able to provide modern, energy-efficient technology whilst catering for the restrictions of such a historic design. “I am excited that we are using an alternative approach to build our home and very appreciative of the contribution that Kingspan is making to our outcome”, concluded van Kan.

The finished product of the Red House on Cranmer Square was aired on Grand Designs on Channel Three in New Zealand on November 7th 2018, three years after the original anticipated airing in series one in 2015.
