Manx passive home

Background

This Manx vernacular cottage designed and built for Mr Kniveton, is located high on the Howe Road with breath-taking views over the Port St. Mary coast on the Isle of Man.

The Beattie Passive system was constructed entirely on the Isle of Man under license by Complete Construction’s Island based workforce, before being erected on site with all materials locally sourced wherever possible.

Winner of the BuildIt Awards Best ECO Home category 2017

Delivery 

Corvalla owner Kevin Kniveton stated: “My experience of my new passive system home has surpassed all my expectations. I knew that my utility bills would be a fraction of what I would ordinarily pay in a traditionally built home, but even I was surprised at how low my quarterly bill over 3 of the most demanding months up to the end of December has actually been.

“Knowing that future bills will decrease much further still when the solar thermal takes over the domestic hot water production and with lower demand generally, I just can’t understand why all homes are not built this way.”

The Isle of Man based Design & Build developers, Complete Construction Services and energy services and renewable technology specialists SNX Ltd completed the first private residential project in association with multi-award winning Passive System build designers, Beattie Passive.

The 4-bedroom Manx cottage named Corvalla, hides a structure built to the highest system design methodology that even goes beyond Passivhaus standards, delivering a home that is so smartly insulated, design efficient and air tight, that a traditional type of central heating system is simply unnecessary.

The Beattie Passive system achieves Passivhaus as standard as well as delivering advanced sound, fire, flood, and radon protection. The system is highly flexible and was able to turn the ideas of the client into their dream Passivhaus home.

The Beattie Passive system was modelled in Revit, a building information modelling software (BIM) that allows users to design a building, its structure and components in 3D, annotate the model with 2D drafting elements, and access building information from the building model's database. This system allowed fast on-site erection with minimal material wastage, as every component was itemised within the Revit design package for each unit.

Learning Points

During the initial discussions, the client was adamant that they wanted to build the best building fabric they could afford, as they believed this was important for long term energy savings and a high level of living comfort.

They decided to invest more money in building the best structure and save on internal fittings and fixtures for their new home. They are already seeing the financial benefits of this decision in their energy bills.

The Beattie Passive system reduces energy demand by up to 90% from year one and provides a much healthier living environment than a traditional built property, due to the high performance structure and the Mechanical Ventilation & Heat Recovery system.  

The cottage has a far higher level of fire safety, sound-proofing, thermal efficiency and air tightness than called for by Building Regulations.

Corvalla was built onsite, over several months. The new innovations from Beattie Passive mean that the system can now be manufactured offsite and erected in a matter of days. Despite enjoying the build process, the client would consider the offsite Passivhaus panel system if they built another home in the future as it delivers all of the same benefits of Beattie Passive, faster!
