This month I started the design work on a new garage in Georgetown that will have walls built from rammed-earth tires, cans and glass bottles… keep your mind open and read on!
Methods and Results
The construction methods are not new; this type of construction is closely related to indigenous building methods that have been used for centuries. However, an architect and builder in New Mexico, Michael Reynolds, is the visionary behind building with garbage. He has been using old tires, cans and bottles for decades, to create homes that are entirely self-sustaining and off the grid. His website www.earthship.net and the documentary ‘Garbage Warrior’ are the best resources on his life and his buildings.
A Michael Reynold’s design and built home
Tire building is an alternative construction technique that uses discarded tires and dirt as building materials. The tires are filled with dirt found on the site and then stacked to form walls. The tires are then covered with a stucco-like finish.
In another eco-friendly building method, glass bottles or cans are stacked like a masonry wall or within a wooden frame using mortar, and the wall is then finished with stucco.
These construction types have many benefits. First, they provide an environmentally friendly way to use items that would otherwise be either in a landfill or would need to be recycled. Second, they can be beautiful. The tire walls can have a smooth stucco finish and will be very thick, with deeply set window sills. When glass bottles are used (two bottoms of bottles are taped together to make an enclosed bottle), the walls bring in a beautiful dappled colored light to the interior of the building. Third, tire or dirt-filled-can construction in a habitable, heated structure (not a garage) has an added benefit of being a solid thermal mass, which holds the sun’s heat from the day and slowly releases it’s warmth throughout cooler evenings. And finally, these alternative construction types are examples of looking beyond status quo in construction practices to create more sustainable buildings.
The genesis of this project is my client, Elizabeth Rose, who is president of Long Way Home, a community-based, nonprofit organization in Guatemala that is building homes and schools using these construction methods. In Guatemala, these construction types are a perfect solution for very poor residents who need shelter and community buildings. In addition to the benefits noted above, building with tires, cans and bottles is cheap; the materials are virtually free, labor costs are low, and the building techniques are easily taught to otherwise unskilled laborers.
Elizabeth saw her family’s need for a garage as an opportunity to showcase alternative environmentally sustainable building practices and to help potential supporters understand the important work that Long Way Home is doing.
From the Long Way Home website:
“Long Way Home’s mission is to collaborate with community members, drawing together knowledge, experience, and creativity into the design and implementation of development projects. For example, by utilizing alternative building methods and community collaboration, Long Way Home has completed Parque Chimiya, a sustainable community park. In addition to the new soccer field, basketball court, and community kitchen, alternative building methods promote the collection and reuse of local garbage which help to combat environmental and health issues caused by trash burning. A healthy environment, Long Way Home believes, is integral in sustaining a healthy and empowered community.”
Making It Happen
The garage design is a simple gable form and incorporates elements (roof lines, window style and details) from the main house. In the craftsman-style wood detailing above the garage doors, we’re planning to use the glass-bottle construction. From a design perspective, we’ll be working on which of the building techniques make sense around the building and on the details with our Guatemalan experts, our structural consultant and the builder.
For the project to be feasible in Georgetown, we will be relying on structural demonstrations by our engineering consultant and on the open-minded building inspector in Georgetown. The construction itself will be a combination of local builders and a visiting team from Guatemala. We’re incredibly excited to see the project and the process take shape. I can’t wait to share the work of filling one tire with Elizabeth! Stay tuned and see the sites below for more information.

Spring is the perfect time for us to air out the house, throw open the windows and closets, and assess what we’ve got. It’s a wonderful time to start thinking about changes to your home – adding that extra bedroom or family room you’ve been dreaming of, remodeling your circa 1950′s kitchen, creating a better connection between your house and garden…Beginning the planning process in the spring is perfect for summer construction.
Renovation and addition projects make more sense than ever this year. Many homeowners have put aside thoughts of relocating and have decided to stay in their homes and work with what they have. Making thoughtful improvements to an existing home, so it will work better for your family and remain useful for decades, is one of the greenest steps you can take. Enormous savings in energy and material resources are found by renovating instead of building new, since building new not only includes the construction materials, but often also includes demolition or disturbing a previously undeveloped site. Savvy homeowners are learning how even small changes, such as adding cabinetry, enlarging an opening between rooms, or even painting can make a world of difference in their enjoyment of their homes.
In our projects, our evaluation and design process includes giving our clients options for additional home improvements they may not have considered to be part of their project: insulation, window and door repair, mechanical, electrical and plumbing upgrades. These not-so-glamorous changes enhance comfort and enjoyment of the home, bring substantial energy cost savings and reduce the home’s negative impact on the environment.
This year and next, we have large rebate, loan and tax incentives available from National Grid and the Federal government for weatherization improvements to existing homes. The following are summaries of what is available. See the websites for more information.
Utility Rebates and Loans:
Through the MassSAVE program, National Grid will fund 75% of the cost (up to $2,000) of insulation, air sealing, windows and caulking/weather-stripping for work completed through July 31st of this year.
Through their Appliance Mangement program, National Grid offers rebates for equipment insulation, energy-efficient water heaters, refrigerators, furnaces and boilers, programmable thermostats, lighting and duct/air sealing. These rebates vary depending on the equipment purchased.
Through MassSAVE’s statewide HEAT loan program, 0%(!!!) loans for energy-efficiency technologies up to $15,000 with terms up to 7 years are available. The technologies covered include water heaters, furnaces, boilers, heat pumps, programmable thermostats, duct/air sealing, building insulation and windows.
Federal Tax Credits
A 30% tax credit (up to $1,500) is available for water heaters, furnaces, boilers, heat pumps, air conditioners, building insulation, doors, windows and biomass stoves. This credit is available for items placed in service in 2009 and 2010.
What do these incentives mean for the average homeowner?
A client of ours decided to include the installation of attic soy-based foam insulation to the other construction items underway in his home. The insulator helped with the rebate paperwork. With the 75% rebate from National Grid, coupled with the 30% tax credit from the Federal government (Yes, it adds up to 105%!), they will get money back for adding insulation! Of course, the increased comfort and energy cost reduction will benefit them for years to come.
Each home is different. Having an energy audit done by a non-affiliated auditor is the best way to prioritize which projects will make sense for your home. Although the costs vary depending on the size of the house, you can expect to pay around $1200 for their full services. The auditors that we work with use blower-door tests to test the air-tightness of the home and an infrared camera test to see where leaks and gaps are in the walls and roof. They use this data with a year of the homeowner’s energy bills to create a written report that includes recommendations for energy efficiency improvements and associated expected cost-savings. They will also perform a follow-up test after the work is complete to verify the system upgrades are working as expected. With the auditor’s information and knowing the incentives available, you are equipped to make the right decision for improvements to your home.
With these incentives in place, this year is the time to take on these projects. It is important to start with an energy audit, to understand the requirements of the incentives and to have a qualifed and informed installation contractor. These contractors have a good handle on the incentives available and usually will help you with the paperwork.
If you need any assistance with your Spring planning or connecting you with an auditor, contractor or installers, let me know. As always, feel free to contact me with any other questions.

One of my fondest memories of living in Chicago was ‘shopping’ in the alleys. My quickest walk to the train was down our 3 block alley: on one side were condo buildings and the on the other were single-family homes. It worked this way – if you didn’t want something anymore, you left it in the alley, NEXT to the garbage, sometimes with a note, and it was usually gone in a few hours. Through the years I collected a great variety of treasures. Among them: lamps, a desk, many many chairs, my now favorite cookbook. My goal wasn’t to be green, but it really was an efficient (cheap!) and practical system.
Now I use www.freecycle.org. If you haven’t checked them out, give them a try – it is basically a local list-serve where members post items they want to give away or items they’d like to receive. It works similarly to shopping in the Chicago alley, but is a bit more civilized.
In construction, the act of restoring or remodeling a home is a form of reuse and salvage. Preservation instead of demolition and new construction saves in energy and materials consumption and reduces demolition landfill. There is a great opportunity in salvaging and reusing materials for remodeling and even new construction projects, if you are aware and know where to look. I was at a friend’s home the other day who found an incredible farmer’s sink in the basement at an open house, asked about it, and got it for a steal.
In addition to the somewhat familiar architectural salvage companies, who generally offer antique architectural elements (light fixtures, mantels, doors, decorative windows, hardware) there are also deconstruction stores that offer even basic construction items (flooring, plumbing, cabinetry). Both types of companies also offer an alternative to demolition and waste of unwanted but usable items, either by donation or in some cases buying the item. See below for some local architectural salvage and deconstruction stores. Many have searchable websites that make browsing easier.
