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

At Terra Firma Earth Building Company, we use as many environmentally friendly materials as possible in all areas of our homes. Our rammed earth walls are strong and permeable, enabling the daytime heat and night-time ‘cool’ to work for an healthy indoor environment.

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

Buildings 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

Buildings that support the environment

Learn how rammed earth buildings produce less carbon in the both build and life-cycle stages than conventional buildings. It is vital that we build more of these homes. A rammed earth home embodies significantly less energy than a conventional home due to the sourcing of natural resources and greater durablity. This means far less impact on the environment.

HISTORICALLY DURABLE

Rammed earth buildings last hundreds, if not thousands of years. Buildings in the Old City of Sana’a, Yemen, attest to this, as pictured, courtesy of UNESCO. Some of these buildings have been standing since the 16th century – some even dating back to the 7th century and earlier.

STRUCTURALLY SAFE

A lot has changed in rammed earth since the 16th century. Today, we use modern engineering practices to make sure that in countries like New Zealand where earthquakes are a known factor, buildings are as safe and smartly constructed as they possibly can be.

FINANCIALLY SOUND

Because rammed earth buildings are made to last, they’ve proven themselves to require a lot less maintenance than conventional counterparts, for decades and even centruries. The cost to build conventional houses may seem ‘reasonable’ at first. But all to often, components don’t even last 15 years resulting in maintance costs building up quickly as the promised life of the building erodes.

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.
