West Auckland Non-certified, eHaus Euro

485
kg

Though modest in size at approximately 70sqm, this remarkable home delivers on the environmentally conscious owners' desires: two cosy bedrooms, one bathroom, a dedicated kids play area, and an open-plan kitchen and living space seamlessly flowing onto a 18sqm covered deck. Carefully nestled among the existing Kahikatea trees, which were safeguarded from disturbance, our team meticulously dug by hand around the semi-surfaced roots, preserving the natural habitat.

Designed and built with precision and care, this home boasts exceptional performance, thanks to a selection of premium materials. From insulated and airtight attic stairs to the Zehnder ComfoAir 180 ventilation unit, wood-alu joinery, and a composting toilet - each component was thoughtfully chosen to deliver a healthy and comfy home.

Embracing sustainability at every turn, all treated timber utilised in construction underwent ACQ treatment - an arsenic and chrome-free alternative to using CCA treated timber, and all products were free from formaldehyde, in harmony with our ecoValues and drive to provide sustainable and eco-friendly products.

All roof water is channelled through a high-density polyethylene pipe to the stainless steel storage water tank, where it is stored and ready for use. This water is then pumped to the kitchen and vanity for drinking, ensuring a reduced contaminant and sustainable water source. Overflow from the stainless tank is directed into the plastic storage water tank, which is pumped to the shower, laundry, and hose taps, providing a comprehensive water solution. All tank water goes thorough filtration, passing through separate UV water filters before entering the house, ensuring that water quality remains pristine and safe for consumption.

This exceptional home meets the eHaus Euro PHI Low Energy standard, highlighting the dedication of its owners and eHaus to not only create a high performing home, but also to honour and preserve the land it sits on.

Adorned in Abodo vertical shiplap cladding and sitting elevated among the native bush, this home stands as a testament to environmentally conscious living.

This project is making significant carbon savings for a better environment.

We believe that our homes should have a big impact on the way we live, but little impact on the land. We've calculated the amount of carbon our homes have saved through energy efficiency from move in day 'til now. At their core, eHaus' are built with the elimination of carbon emissions in mind - so we're not only creating healthy, comfy & high performing homes, but spaces that don't cost the earth.
