The Future
We can build
Together

Invest in the environment

Rammed earth homes have a much ligher carbon footprint than many conventional homes. It comes down to using locally sourced materials that are as natural and eco-friendly as possible, while still meeting building and structural safety requirements.

Invest in your health

We use eco-building materials and techniques that dramatically reduce the likelihood of asthma and allergies. Rammed earth walls are permeable, meaning they absorb and transfer heat, cool, and moisture. This creates a stable indoor environment that’s good for your health.

Invest in durability

When something is durable, it lasts. Rammed earth walls are built to last hundreds, if not thousands of years with minimal maintenance. This long lifecycle dramatically lightens the impact that rammed earth buildings have on the environment and your finances.

Healthier for you

Homes that support your health

Understand how we create homes and buildings that contain less toxins than conventional homes – from the earth mix in the walls to the wood stain or oil on the windowsills. Learn how the 350mm + thick walls keep indoor humidity at healthy levels for you and your family and, due to using the sun’s warmth, require less mechanical heating and cooling.

Healthier for the planet

Homes that support the environment

Learn how rammed earth buildings produce less carbon in the both build and life-cycle stages than conventional buildings. We build homes with a light carbon footprint. A rammed earth home embodies significantly less energy than a conventional house due to the sourcing of natural, local resources and incredible durablity. We build homes that last.

HISTORICALLY DURABLE

Rammed earth buildings last hundreds, if not thousands of years. Take, for example, the Old City of Sana’a, Yemen, courtesy of UNESCO. Most of these buildings have been standing since the 16th century with a handful built in 7th century.

STRUCTURALLY SAFE

Today’s rammed earth homes blend 16th century earth building wisdom with modern engineering practices. In New Zealand, we have highly-respected earth building codes that ensure structural safety as well as comfort and design.

FINANCIALLY SOUND

Rammed earth buildings are made to last. They’ve proven themselves to require a lot less maintenance than conventional counterparts for centuries. The cost to build conventional houses may seem ‘reasonable’ at first. But all too often, conventional build components break down quickly and require costly replacement and repair.

How we do rammed earth

Here we are working on Peter and Jo Birch’s fantastic property in Thames. Terra Firma CEO Paul Geraets might design the homes but he’s still capable of being on the tools! This is ‘how we do’ rammed earth – layers of earth being compacted into wooden forms to create strong, stunning, natural walls.
