eHaus Euro - Passive House Low Energy Standard - Non Certified
This a small but perfectly formed eHaus is nestled in a private retreat away from the business of life. It has all you need including 3 bedrooms and an amazing private outdoor area linking directly to the internal living space. With all of the normal eHaus features and some extras this home has a very light footprint on the planet and generates most of the electricity that is needed to run the home through the year.“From the time we had our kick off meeting …. About 20th March…basically we came out of Consent on the 21st of July, so been a four month process. Working together between the design and the builder and ourselves, very tightly together, has been the right way to go” Robin
