Building a house is hard work. A decade ago my mum and I built an eco-house together. We loved it—the freedom of designing what spaces we wanted, the excitement of choosing only materials we wanted to use, and most of all the pure joy of moving into the finished house. I have lived in many places but up until then I had never realised that a house could actually make me happy. Sitting on a reclaimed-wooden floor warmed by the sun streaming in through a draught-free window, knowing my water was being heated, and electricity generated, for free by the sun, I felt a surge of happiness.

I also suffered from a wave of exhaustion, a realisation that there was no money left, a worry about all the jobs still to do, and a fear about whether the house would stay standing, endure a storm, and if the systems (like the rainwater harvester) would carry on working. But it was at this moment, despite the work, stress, and worry, that I fell in love with eco-building and its possibilities. I also realised how terrible most of the other houses I had lived in had been. They were cold, damp, draughty, dark, and even mouldy. Since then I have been exploring how we can build better houses that are affordable, comfortable, and ecological.

Communities are sites of innovation and experimentation in eco-home design. I first encountered eco-building at the Centre for Alternative Technology in Wales, where they were experimenting with timber-frame and strawbale construction. The buildings of eco-communities shape many communities’ functions. As Jan Martin Bang argues, “we are what we live in. When we plan our buildings, we are also planning what kind of society we want to create…we make the buildings and the buildings make us.”[i]

Karen Liftin [ii] calls this the “architectures of intimacy” where buildings in communities are purposefully designed to encourage social interaction. When designing and building using circles—as a house shape, as houses around a communal circular garden, as an arrangement for seating—the circle is used to avoid hierarchy and enables everyone to see each other. Building houses together is also a way to build community. Using materials such as strawbale which require little specialised training means anyone can get involved. Yet building collectively and in community is not always easy.

Eco-communities benefit from a shared work force, shared infrastructure costs, and economies of scale, and builders benefit from mutual support and a niche space in which to innovate and take risks. However, the costs of building in eco-communities tend to be the time required to make decisions and an experimentalism that can mean ignoring established building approaches or building physics. It is easier and cheaper to build eco-homes in communities, but the results are more variable.

Building in a community requires effort to be focused into communal systems of decision-making, living together, and processes of sharing. Numerous social and economic benefits result from this, but the houses themselves can suffer. In some cases eco-communities offer important space for periods of innovative and creative experimentation that go on to influence eco-home design elsewhere. But those who seek to focus on housing can be accused of specialisation or elitism, and be marginalised.


Building together is cheaper than building alone. Numerous strategies can reduce the costs of construction; building smaller houses, using cheap marginal land, using reclaimed materials, or reducing labour costs through self-build. Eco-communities use all these tactics and some have managed to build incredibly inexpensive homes. For example, Tony Wrench built his roundhouse at Birthdr Mawr (Wales) for a total cost of $4,000. However, eco-communities are also able to benefit from their size to reduce the costs of building by sharing infrastructure and devising cost-sharing schemes. LILAC (Leeds, England) developed a new home ownership model to ensure the houses remained affordable. Residents only pay a housing charge of 35 percent of their income. In effect the higher earners subsidise those on lower incomes.

Eco-communities also provide a ready pool of labour that significantly reduces costs. Labour costs in building are conventionally half of the total costs of construction. Communities also buy construction materials in bulk, further reducing costs. Clutching to the steep hillside of the Sangre de Cristo Mountains north of Taos, New Mexico, the Lama Foundation has been building since 1968. Principally a spiritual centre, it has an eclectic mixture of eco-homes. Building here is a collective process and part of a spiritual practice for many; one resident said they “build with clay, mud, and love.”

Building is a process of sharing—sharing tools, skills, and roles—as Chelsea Lord, a volunteer explains: “Building a building has to be a collective thing… In regular construction it’s all portioned out…everybody is separate… It’s just so un-cohesive and it ends up costing the homeowner so much for all these specialised people to come in with all these really expensive specialised tools. Whereas in natural building the same crew of people all build together start to finish, and you don’t have to have a bunch of specialised tools and you don’t have to have a bunch of specialised knowledge. If there is someone directing, you don’t have to know how to use a nail gun or a [circular] saw. So it’s just much more human, and then they’re so beautiful when they’re done, they just feel good.”

Perhaps the most effective way to build more ecologically is by building smaller homes and by sharing large communal spaces and facilities. Eli Spevak (Peninsula Park Commons, Oregon) explains: “The most effective thing you can do is simply build smaller and attached housing. Most of the carbon impact of housing comes from heating it, so if you have a smaller space you do not need as much energy to heat it and if it is attached, side by side with your neighbours, then you also need less heat because the common walls share the heat across the buildings. One of the things we do is build smaller spaces and then have common spaces to provide a little extra space.”

Building is a process of sharing—sharing tools, skills, and roles…

In Panya Project (Thailand), large communal spaces include the shared kitchen, gardens, sitting area, office space, laundry, workshops, greenhouses, guest space, and bathrooms. Panya Project is near Mae Taeng, Chiang Mai, northern Thailand. Established in 2004, the 10-acre site has become a place for experimentation and education in permaculture and natural building. Built using either sun-dried adobe bricks or wattle and cob, homes are purposely small—one house is just three metres by four and a half metres floor space, because it contains only space for sleeping and privacy. Most simply contain a bed and some storage space. All cooking, dining, and washing occur in communal spaces. This reduces both build time and material requirements.

Even in cities, eco-communities often offer small personal spaces compensated for by large communal areas. At Los Angeles Eco-Village, an eco-retrofit of an old brick apartment block in downtown L.A., residents rent private apartments with individual kitchens and bathrooms, but they share the gardens, bike storage room, bulk food storage, meeting space, and a large entrance seating area.

Despite the compact size, the physical and emotional sense of home extends far beyond the house. Peninsula Park Commons, initiated by Eli Spevak and Jim Labbe in 2003, is a cohousing development created by renovating six existing houses and building four new structures. Beyond the buildings lie the communal gardens and raised vegetable patches. Rather than stop the development at the edge of the plot, however, Peninsula Park Commons stretched out into the street and reclaimed the sidewalk with planters. Plant beds overflow and merge the communal garden with the public space. This is a very deliberate approach; in Eli Spevak’s words, “we want to slip into existing communities.” They hold community events like their annual community ice cream social and garden party to reach out and draw people in.

This sharing and communal spirit is a vital support mechanism for eco-building, especially when it involves risk-taking. Being surrounded by like-minded individuals and communal infrastructure provides invaluable mutual support. Kailash is an urban ecovillage situated in a 32-unit apartment building in Portland, Oregon. All the units are one-bedroom small apartments and the community is gradually eco-retrofitting the whole building. As Maitri, a cofounder of the ecovillage, argues, “you really have to be the model. You have to be what you want other people to be. So you really need to work on your own self first.”

Encouraging change requires appropriate infrastructure, as Maitri explains: “We have individual [garden] plots so that people can put themselves into that and be creative. I think it’s very important that people have that opportunity. Like the bike parking—we put those bike-parking racks and oh, we need two more already! You provide a community; people come and have a good time.”


If communities self-build they take time and energy away from other tasks. Even using external volunteer labour has costs—the time taken to train newcomers, the costs of repairing mistakes, or the inefficiency of unskilled labour. Lama Foundation struggled to maintain their buildings because they relied on volunteers to build, and yet natural materials were used which require regular attention and patching. The community didn’t anticipate this need for maintenance. In Richard Gomes’ words, “we are financially OK, but we do not have the staff to maintain the buildings. We need a bigger staff if we are to only have lime plasters; that is why we have started to use some regular plaster—stucco—on external walls.”(Stucco has a bigger environmental impact.)

The cost of labour—whether it is measured in time, efficiency, training requirements, or the consequences of using unskilled labour—needs to be understood. Diana Leafe Christian proposes that all eco-communities create a budget for labour needs: “if you don’t create a labor budget, you’ll be forever tempted to add new projects and ask the community to allocate labor credit for them, leaving you wondering why you have six half-done construction projects sitting around for years [iii].

Eco-building therefore requires significant negotiation, time, patience, and compromise, and careful attention to decision-making structures. The more democratic and shared the approach, the longer the process takes. At Kailash Ecovillage effort went into building community, as Ole explains: “We have a weekly community night…when we moved in the residents didn’t know each other and now everybody knows almost everybody…so it’s created a tremendous sense of community out of basically zero community before.”

Eco-communities need to design their buildings and shared spaces to accommodate diversity.

But they decided against the democratic approach in decision-making in order to save time and reduce conflict. According to Ole, a cofounder and owner of the land and apartments, “we’re a hierarchy—we’re basically a benevolent dictatorship here and we take the decisions and we invite a lot of community input but ultimately we are the decision-makers. I think for some people that actually is probably preferable because most people don’t want to be involved in a lot of the decisions we do—they just want things to be done and maintenance to be done and there’s no need for them to give any input in that.”

Ole and Maitri adopted this approach because when they were part of a previous attempt to establish cohousing in Portland, they felt that the consensus decision-making approach paralysed the progress of the build. In Ole’s view, “it just takes forever as there are so many voices…and they agonise over these silly things: the colour, the finishes, and stuff like that.”

Lydia Doleman, a self-builder, argues that “buildings have the capacity to equalize people or segregate them.” [iv] Eco-communities need to design their buildings and shared spaces to accommodate diversity. While communities have developed new forms of interpersonal relationships, often rejecting the notion of a nuclear family, other forms of diversity have been paid less attention, especially race, disability, and class. Camphill communities seek to provide places for disabled people to live and work, and new cohousing communities are being designed for seniors, but in most eco-communities little provision is made for differently abled bodies.

Finally, Jonathan Dawson argues it is time for eco-communities to start to accept the need for professional support: “as planning regulations have tightened, it has become more difficult for groups to create substantial new settlements without professional assistance.” [v] Eco-communities are generally quite poor at collaborating with professionals. While many examples of outstanding, high quality eco-building exist in eco-communities, in many other examples little reference was made to existing building knowledge, resulting in simple mistakes. Communities can fall prey to anti-professionalism, a rejection of the importance of experts, specialists, or building professionals such as architects and engineers.

The journey of Twin Oaks (Louisa, Virginia) exemplifies the tension between unskilled building and a professional approach. The community had the input of professional architects and builders who had given up their jobs and settled there. Over time some of these builders began to get frustrated with the need to work with volunteers and constantly teach others, and eventually a key builder departed. At Dancing Rabbit (Rutledge, Missouri), Alex Whitcroft, a trained architect, sought to overcome this tension by being a “brave specialist,” someone who lived on site and worked with residents: “what is needed is not specialists but…brave specialists who can listen, ask the right questions, and design with communities while integrating their expertise.” [v]  This compromise approach is perhaps the most productive way forwards in terms of ensuring quality eco-buildings.

Ten things to consider when eco-building in community

  1. Sharing space, objects, equipment, and skills reduces costs and environmental waste, but robust systems of sharing with clear agreements are needed.
  2. Living in compact spaces works if there is communal space available to share, particularly access to green spaces.
  3. There is a need to balance participation in eco-building and collective decision-making with the need to complete projects and take risks.
  4. Without explicit effort to encourage diverse types of residents and self-builders, eco-building will likely remain the preserve of the white middle classes.
  5. Although learning by doing is useful, the need to learn from the past, from experts and professionals, and to seek out existing knowledge is too often ignored, wasting time, effort, and resources.
  6. That many eco-communities relied upon volunteers to build (and maintain) their houses has unintended costs. Sometimes this results in inefficient building practices, incomplete projects, failure to consider and plan for maintenance, and poor quality buildings.
  7. Residents and self-builders rely upon mutual support in building their eco-homes, not just in sharing physical labour but also emotional support.
  8. Eco-building does not necessarily require destroying existing structures. Such structures can be renovated and often there is still space in which to add new additional eco-homes.
  9. Eco-communities’ focus on social issues, on commitment, building community, and collective governance, has sometimes led to neglect of the need to learn and understand the physics of how buildings work.
  10. Building by anticipating future change in occupiers, and thinking through how to, for example, maintain affordability, are essential to the success of eco-homes.
