A visit to Fishleys Passivhaus

Fishleys Passivhaus opened its doors as part of the “re-energise” 2018 AECB convention in September.


Talk about starting afresh… In summer 2015 owners of Fishleys decided to downsize from their family home in Worcestershire and undertake the demolition of an old barn on their plot to replace it with a Passivhaus.

The construction of this detached timber frame home, designed by PHT patron member Architype and built by main contractor Mike Whitfield Construction Ltd, began in 2016 and achieved Passivhaus certification in March 2017. 

The home was designed in close consultation with the clients. It took a sensitive approach; by making the most of the views to the Malvern Hills and the clients established garden, and through choosing a range of natural materials.

To document this project from the roof down and the ground up, the owners kept a blog with monthly updates which you can read here.

The clients are interested in testing how the project is performing in accordance to its predictions, such as how much will the temperature fluctuate, whether they overheat, and how much solar they will produce.
