Corvalla, a 4-bedroom new build, designed in a Manx vernacular style, was the first Passivhaus standard home to be built on the Isle of Man.
“Even I was surprised at how low my quarterly bill over the most demanding months up to the end of December has actually been… I just can’t understand why all homes are not built this way.”
Mr K Kniverton
We spoke to our client, Kevin Kniverton, about his experience of designing and building a Passivhaus using the Beattie Passive build system.
When and why did you begin planning to build your own home?
We had always wanted to build our own home and we were fortunate enough to have land in the south of the island. There was an existing ruin, which was knocked down and replaced with a Passivhaus.
What was your first impression of Passivhaus when suggested by James Vickers at CCS?
Having an engineering background, I was very interested in the idea and the potential benefits. Initially, I had to convince my wife, but she’s a convert now.
How did you find the Beattie Passive design process and working with SNX and James Vickers?
It worked very well. The original construction drawings were changed from a traditional build to Passivhaus, but took no longer and we had no concerns about the change in the construction method.
What impressed you most about the build process?
We were struck by the attention to detail. Every joint and seal is 100% accurate throughout the entire build. The speed of the on-site manufacture and delivery was similar to a traditional build but the quality and level of detail provided by CCS was impressive.
What were you most looking forward to about your new home?
As this was a Passivhaus project, we were looking forward to seeing just how much energy we would save. This was our family’s first proper home (having lived in a small flat previously) and, as an engineer, the technical side interested me from the outset.
What has been your experience of living in a Passivhaus and how does it compare to a traditional house?
The minimal level of external noise is noticeable. We live in a windy spot overlooking Port St Mary and the triple glazing and overall insulation has been a revelation! Furthermore, the solar panels provide us with very hot water and we’ve noticed a better level of air quality within the home.
Is there anything that has surprised you about living in a Passivhaus?
The overall performance and warmth of the house stays constant throughout the year, regardless of the season. Despite being a traditional style of home, the Passivhaus element takes it to another level.
