Product Description

Are you ready for the Cob Cottage? This is a building method so old and so simple that it has been all but forgotten in the rush to synthetics. A cob cottage,cobb, however, might be the ultimate expression of ecological design, a structure so attuned to its surroundings that its creators refer to it as "an ecstatic house."

The authors build a house the way others create a natural garden. They use the oldest, most available materials imaginable—earth, clay, sand, straw, and water—and blend them to redefine the future (and past) of building. Cob (the word comes from an Old English root, meaning "lump") is a mixture of non-toxic, recyclable, and often free materials. Building with cob requires no forms, no cement, and no machinery of any kind. Builders actually sculpt their structures by hand.

Building with earth is nothing new to America; the oldest structures on the continent were built with adobe bricks. Adobe, however, has been geographically limited to the Southwest. The limits of cob are defined only by the builder's imagination.

Cob offers answers regarding our role in Nature, family and society, about why we feel the ways that we do, about what's missing in our lives. Cob comes as a revelation, a key to a saner world.

Cob has been a traditional building process for millennia in Europe, even in rainy and windy climates like the British Isles, where many cob buildings still serve as family homes after hundreds of years. The technique is newly arrived to the Americas, and, as with so many social trends, the early adopters are in the Pacific Northwest.

Cob houses (or cottages, since they are always efficiently small by American construction standards) are not only compatible with their surroundings, they ARE their surroundings, literally rising up from the earth. They are full of light, energy-efficient, and cozy, with curved walls and built-in, whimsical touches. They are delightful. They are ecstatic.

The Hand-Sculpted House is theoretical and philosophical, but intensely practical as well. You will get all the how-to information to undertake a cob building project. As the modern world rediscovers the importance of living in sustainable harmony with the environment, this book is a bible of radical simplicity.

Building a Cob Cottage Step-by-Step excerpted from Part II: Building the Cob Cottage

EVERY COB BUILDING IS UNIQUE, but most require the same basic steps. The order of some of these steps is critical; others can be rearranged as desired. For a first-time builder, it can be very useful to map out the sequence of all construction tasks. Following is a sample sequence to help you think through your project to completion before you begin. The next ten chapters walk through each of these steps in great detail.

* Select your building site very carefully, for best exposure to winter sun and for good drainage. * Decide in advance roughly what spaces, shapes, and features you will need, both indoors and out, based on the scale of your own activities. Make many sketches and models. Keep the building as small as possible. If you need more than 400 square feet, consider phasing the project to complete the most essential sections first. * Work on a scale model of the building, including site features such as trees and slope. * Decide the wall plan in detail, especially where doors connect the indoors with outdoors. Design the roof at this point, including the roof and how it is supported. Make a full-sized mock-up of the building on the site. Spend time in it, and imagine what it would be like to live there. * Assemble on-site all building materials you will need for enclosure, including glass, lumber, rocks, hardware, pipes, wires, and so forth. Gather your tools, scaffolding, and water storage. * Check your soil, and assess by making test mixes and test blocks what needs to be added for the best cob mix. Measure your proportions and calculate the amounts of sand, clay soil, and straw you will need. Plan out and prepare mixing spaces close to the building. * Arrange delivery of sand, clay soil, and straw as needed. Store deliveries close to and uphill from the building, in locations that won't impede work. Make sure straw is stored under cover, off the ground. * Stake out your design and finished levels precisely on the site using many strong, firmly driven stakes. Adjust for the last time. * Clear and level as little as possible. Grade away from the building so that water runs away on all sides. Set aside excavated soil for gardening or making cob. * Dig drainage and foundation trenches, lay in drainpipe, insulation, plumbing, and wire connections; backfill trenches immediately with drain rock. * Build the foundation stemwall, setting in door frames or frame anchors and joists if floor will be suspended. Leave openings for utilities and water lines in and out. * Tamp the subfloor, lay several inches of drain rock, and, if you will be using an earthen or other mass floor, lay the floor base coat. * Frame the roof, either on permanent posts or on temporary posts that will be removed when the walls are complete. You may also wait until the cob is nearly finished before framing the roof. * Experiment with cob mixing techniques -- for speed, ease, enjoyment, and different numbers of workers. Concentrate on gradual improvements. Apply your mix, probably at first by fork, trodden, then using "Gaab cob" or cob loaves. Sew it all together solidly with your fingers or a "cobber's thumb." Try to raise all the cob walls at the same rate. * Make sure you build vertical or tapered walls; don't leave big bulges or hollows. * Pare each new part with a machete or handsaw before it gets too hard, leaving it ready to plaster as you build. * Set pipes, wires, outlets, junction boxes, and so on into the walls as you build. * Build in windows as you go. Bury "deadmen" in the walls, wooden anchors to which you can later attach door frames, shelving, countertops, and so on. * Sculpt built-in furniture, bookshelves, niches, and alcoves. * Let the walls dry and settle somewhat, then build loft or second-story beams, joists, and ledgers directly into the cob if the wall is loadbearing. * Locate roof deadmen one and a half to two feet down from the rafters. Complete the walls. * If the roof is on, you can now enclose and heat the building. If not, now is the time to build the roof. If the roof will be heavy, allow the cob to dry throughout first. * Do final ceiling work. * Finish interior built-in woodwork, counters, cabinets, interior door frames, and plumbing fixtures. * Apply interior plaster. * Lay a finish coat on floor. Seal an earthen floor with linseed oil and beeswax. * When interior plaster is dry, apply natural paint, lime wash, or alis. * Plaster the exterior, if desired. * Have a big party! Invite everyone who helped you build.

I Spent Hours With This Awesome Book5
I paid full price for this book at a retail Book store (I wish I had bought it here!). I have 2 other books on cob building also (Becky Bee's "The Cob Builders Handbook" - Which I highly recommend also & Michael Smith's "Cobbers Companion", I also recommend but Becky's, I feel is the better of the two.) However, THIS book stands out considerably. It is the MOST awesome book on cob building. It has wonderful photographs & drawings including additional privacy courtyard/outside ideas etc. There is nothing out there that can compare to this book to spark ideas and show the beauty, versatility & many options & benefits one has in cob building. I highly recommend this book to anyone who has even a slight interest in earth homes/cob building. If you are very interested in this or a related subject(straw bale etc.) you will LOVE this book!

can't be improved upon5
For your inspiration, edification, and step by step hands-on & how-to, this book just can't be improved upon. Long checklists to help you choose the perfect piece of land and how to situate the location of your home. A tutorial in using passive solar to heat your house. How to design its interior to embrace you, find your materials as inexpensively as possible, gather your tool kit (what's essential, what's not), test the soil you have, make cob samples and evaluate them. Starter projects such as walls, benches, and stoves. Mixing techniques, building techniques, finishing techniques. The history of cob, the durability of cob, a trouble-shooting guide. How to make your own paint, make your own floor, insulate, remodel the house if you want to, where to put the wiring, every practical detail is included as well as the philosophical... you will find inspiration on every page. Countless examples and real life stories are included, as well as color photographs of cob structures all over the world. This book doesn't just critique the current system, it shows you a way out!

About more than just cob, this book is required reading.5
The Cob Cottage Company literally invented a building technique called "Oregon Cob". Their collective development includes not only high-quality cob mixing techniques, but also a holistic design and construction approach to suit both the building material and the sustainable living philosophies of the builders. The Cob Cottage Company has used this book to summarize more than a decade of research and development of both mind and mud. Each author has focused on one of three sections of the book and each contributes something unique.

Ianto appropriately begins the book by not only giving a history of earth and cob building, but also by helping the reader redefine their view of housing. I've read this section 3 times thus far. It contains so many great ideas and insights that the reader may want to keep a journal to remember them by. The authors' ideas concerning intuitive design with natural materials are amazing, yet proven. Ianto is definitely critical of industrial architecture (he was a trained and licensed architect in the UK) and corporate control, but not in a way that is unbearable or preachy. I find these sorts of viewpoints incredibly refreshing when communicated so well, whether or not I completely agree with them or not. Evans covers virtually all aspects of site selection and home design while also including interviews with a few cob home owner/builders. This section is surely the real magic of this book and may greatly alter the reader's perceptions of both shelter and its relation to the surrounding environment.

Part 2 describes the actual construction of a cob cottage. It is mostly authored by Michael Smith, who has authored another book detailing cob construction, "The Cobber's Companion". This section of the book provides plenty of helpful advice and creative ideas that the Cob Cottage Company and other cob enthusiasts have developed over the years. None of the authors pull any punches. They obviously have pursued their Cob Revival with intelligent passion, being certain that potential builders understand the potential pitfalls and the keys to success. They know that failed projects can do have as much impact on society's acceptance of cob and natural building than successful projects. Smith and crew really try to help the reader plan for success and encourage them at every step. While the reader would do well to take part in a cob building workshop for hands-on experience, they will get a very thorough understanding of the steps and techniques involved by reading this book. The authors' credibility on cob construction is never in doubt here.

Part 3 is an Onward by Linda Smiley. She attempts to spur the reader on to the next step(s) after reading this book. The entire book is treated as a beginning to a rewarding journey, not just an end to its own means. Smiley provides valuable advice on attending and sponsoring cob workshops. She also expands upon Evans' introduction to alternative living ideas and encourages the reader to live in the moment. While this section is much shorter than the other two, it is important to the book. Ianto gets the reader fired-up about building with cob, Michael tells the reader how to actually do it, and Linda encourages them to put their new-found ideas into action.

The Cob Cottage Company recognizes that cob is but one component of natural building. While the authors' passion for mud is ever-present, so also is their understanding of region and site-specific alternatives and constraints. The Cob Cottage Company integrates and shares ideas with the growing community of natural building enthusiasts, always attempting to create solutions appropriate to the need. Oregon Cob truly offers amazing potential for affordable, durable, healthy housing, especially to owner/builders who can greatly offset the dollar cost of a home with their own efficient labor. Cob offers much greater earthquake resistance than unreinforced adobe, creating a simpler building process that anyone can learn. My review would not be complete without admitting that this book gave focus to numerous nagging doubts that I've long had about American culture and homebuilding. Though I have worked in residential construction for nearly a decade, I could never quite describe exactly why I found our homes (and my job) so inadequate until I read this book. Though my worldview and opinions continue to evolve with each new day and discovery, this book was surely a milestone for me. It changed my life in ways I have yet to even realize.
