eHaus Euro - Certified Passive House Classic

This imposing residence in a French style was built for three generations, with two homes connected by a very large kitchen and pantry.  It also includes office space for the young couple who work from home. It is testament to the flexibility of the Passive House standard, which can accommodate different aesthetics. An extremely high quality build that performs as well as it looks.

“It’s great, it’s extremely comfortable and it’s a very elegant form of living, we’ve found, you don’t really notice temperature variances at all and if you do notice a slight warming or cooling it happens very gradually, adding to that the lack of condensation, mould, even dust it’s really just an incredible way to live” – Harpal
