We blog about earth building and efficient designs, but we pay our bills by building rammed earth walls on the east coast of Australia.

Australian Finacial Review – Rammed earth houses woo the world

August 16, 2016

Luke Mahony

Luigi-Rosselli-Architects-The-Great-Wall-of-WAIt is worth noting when rammed earth gets mentioned in major newspapers, as just happened in the Australian Financial Review. And it well deserved recognition for Luigi Roselli‘s great wall of WA (constructed by Murchison Rammed Earth) described as “one of the most compelling residential projects of our times – a series of humble bungalows that has taken the world by dust storm.”

It was great to see the thermal approach to the climatic challenges of WA win so much recognition, with the Arch Daily, an architectural journal award Luigi Roselli the 2016 Building of the Year. The online poll of 55,000 users of the site – “pegs Rosselli alongside the likes of Pritzker Prize laureates Renzo Piano and Herzog & de Meuron.”

nomaaThe article goes on to reference the walls we recently completed…”in fact, rammed earth is turning up in some elegant city builds. Anyone who dined at the Sydney pop-up of Noma of Copenhagen early this year will have eaten within rammed-earth walls designed by the Melbourne studio Foolscap.”

“Compacted from soil sourced in NSW, the rammed-earth walls of the $450-a-head eatery were intended to give the Noma dining room “a sense of solidity, of permanence”, says Foolscap principal Adele Winteridge. The walls also efficiently evoked the terroir that Danish chef Rene Redzepi famously scours for native ingredients.”

 

The Financial Review notes “as one of the world’s most sustainable building techniques, it speaks eloquently to the zeitgeist.”

Terra Awards – the first international prize for contemporary earthen architecture

July 29, 2016

Luke Mahony

Quite a significant award was announced recently in CRAterre in France. The Terra Awards was created  to “not only to identify and distinguish outstanding projects, but also to highlight the audacity of the project owners for choosing to use earth, the creativity of the designers and the skills of the craftsmen and entrepreneurs.” It creates an overdue showcase that reveals what can be accomplished with earth.

089_AUS_TheGreatWallofWA_LuigiRosselliArchitectsA notable prize was for collective housing category for Australia/Italian architect Luigi Roselli and “The Great Wall of WA”. Built by Murchison Stabilised Earth in the Pilbara region of Western Australia , it represents a logical approach to desert living. The high thermal mass of the walls and earth embankment will even out the high night and day fluctuations of temperature. Naturally cooled… naturally cool.

150_ESP_ViviendaVernacular_AngelsCastellarnauThe winner of the individual housing category was the “21st Century Vernacular House” by Spanish Architect Angels Castellarnau Visus. The house was built with rammed earth, but with a twist. They added barley straw to the mix to “increase the thermal behaviour”.  I would question the actual performance of this method as the straw does not provide a thermal break (i.e. the insulative property of the straw is by-passsed by the thermal bridges). Edra-Arquitectura_foto-doblestudio_004I love the look of the internal mud brick wall and their selection of natural materials like earth, straw and stone, hydraulic lime, ceramic tiles, sheep wool and wood and natural cork. It does a great job of continuing the tradition and vernacular of the region, whilst providing local employment and community.

305_Library_Terra_Award_Laureate_41-1In the Cultural Public Facilities category, local labour was used in the  construction of a library in Sri Lanka. It was used for knowledge creation and retraining – and the subsequent transformation of the army into a society-building institution – intends to support the much needed demilitarization of the country in the aftermath of its 30-year civil war. It is great to see earth building tradition of asia acknowledged.

178_CHN_MaanqiaoReconstructionProject_JunMuAnother award goes to the Chinese government for their Post Earthquake rebuild. Using a master plan that emphasised excellent thermal performance with traditional designs and materials, they have shown what is possible on a large scale with some government vision.

212_MAR_HimmelstreppeStadtOrion_GreenVoth_updVision of another kind comes out of the plains of Morocco that creates the stairway to heaven. Created by artist Hannsjörg Voth over 23years, it received the landscape award and has towers of over 17m and uses local techniques.

Congratulations must go to CRAterra for their great effort in organising and presenting these wards! For more information, go to terra-awards.org.

Anna Heringer  designs some beautiful buildings with earth and bamboo. This is a great interview in the architectural review –  “winner of both the Aga Khan Award for Architecture and the AR Emerging Architecture Awards for her educational buildings in Bangladesh, Anna Heringer reasserts her beliefs and ambitions with every project, staying faithful to her approach yet challenging what new architecture can be created from the same raw materials and with the same design ethos.”

Lime rendered rammed earth in Portugal

March 21, 2016

Luke Mahony

All photos by João Moragdo via DesignboomI have always been a big fan of lime rendered rammed earth, which is quite a traditional way of sealing rammed earth in many cultures (as well as clays and oxides). We have several internal rammed earth walls in our house which we have lime rendered. The special feature of lime is that it allows the earthen walls to breathe as well as being antifungal and antibacterial.

Design Boom recently featured a Vineyard house in Portugal that has most internal walls plastered, but has left some sections exposed to frame the earth walls. It was designed by Lisbon based Blaanc architects. It looks stunning!

lime-rendered-rammed-earth2According to design boom, the “primary living space is contained within a rammed earth volume, which adjoins a sheltered outdoor terrace. internally, the use of rammed earth ensures greater thermal and acoustic comfort, providing a cool environment throughout summer months.”

Noma Australia rammed earth walls

noma8Rene Redzepi recently open one of the world’s best restaurant in Sydney.  ‘noma‘ Australia is located at Barangaroo in Sydney. We were commissioned to build two bars and an entry wall which doubled as a cloakroom.  The walls were made to reflect the colours of Australia. This was achieved with oxides.

 

img_20160221_100012.jpgRene has become quite influential with his use of foraged foods and local ingredients. I feel earth building sits nicely with his philosophy of using what is local and available.  Here are some photos of the project.

Bush Fire and Rammed Earth

February 4, 2016

Luke Mahony

bushfiresIt is the middle of bush fire season in Australia, and research has just been released on the most efficient way to protect structures from fire attack.

CSIRO bushfire urban design research leader Justin Leonard said the best way to protect homes against embers was simple – use materials that don’t burn. He said using a steel frame for the house was a good place to start, along with building materials like brick or rammed earth.

Queensland University of Technology consulting research architect, Ian Weir told the SBS recently “there is a common misconception bushfire safe homes are very expensive to build. Simple design elements can be relatively cheap whilst minimising the amount of vegetation required to be cleared.”

Dr Weir said it was often complying with energy regulations that cost homeowners a lot of money, and many of the measures taken to keep a house energy efficient, like using rammed earth, would also keep it safe in a bushfire.

He said bushfire-proofing elements such as toughened glass, window mesh and window shutters could also fulfill everyday roles such as fly screens or shades. “Bushfire prone areas are often really hot in summer but quite cold in winter…and a lot of the things you need to make a house thermally comfortable are also bushfire proof,” Dr Weir said.

As a member of the Rural Fire service it would be good to see common sense prevail in respect of both building design and land clearing. Non combustible building materials would also have a big impact on house fires that claim more lives and houses than bush fires. Read the full story here.

Nepal – Alternative post quake rebuilding

January 25, 2016

rammedearthbambooLast April 2015, a massive earthquake devastated many parts of Nepal with 600,00 buildings. It is very exciting to hear the efforts of Nripal Adhikary and his group Abari who are promoting a safe, sustainable and cost effective method of rebuilding.

Their aim is to use local available materials as well as labour! “The benefit of using bamboo is that once treated it is durable, as strong as steel, but flexible. Rammed earth walls are extremely strong and last a long time,” said Adhikary in a recent article in the Nepali Times.

Said Adhikary: “The main challenge about alternative earthquake resistant housing is to change the mindset. We have been able to change the people’s mindset but we are still waiting on the policy makers.”

downloadAbari have also build a school with open source plans for a school design using earth and bamboo which you can find at this link.
