At the Fourth Pig we have extensive experience in natural and green building, from home retrofits to new construction, to installing solar panels and a lot in-between.  We also offer courses and workshops to teach people skills in natural building and sustainable energy.   In some cases we can incorporate workshops into the building process (such as with some aspects of a straw bale home).

We offer general green contracting/construction including carpentry, straw bale, earthbag and cob construction, healthy interior finishes, earth and lime plasters, solar assessment, PV design, solar installations, building deconstruction and salvage.  You can learn more about natural building here.

We can work from an existing design or suggest an architect to work with you and us in a collaborative design process.  

In short we build more sustainable shelters by using environmentally friendly materials, recycling, re-using and reducing waste. 

Fees - fees vary widely depending on the nature and scope of the job.  Fee subsidies may be available for schools, non-profit and charitable organizations. Please contact us for more information.


What’s in a name?
Our name is a play on the tale of the Three Little Pigs.  We say the fourth pig is the wise one who built the house out of straw bales, installed solar panels on the roof and used the breath of the wolf to turn a turbine.




Glen Byrom

Glen's work in construction over the past 12 years has focused on natural construction and renewable energy, including working on over 30 strawbale houses and PV installations. He has taught several Natural Building workshops at Solar Energy International, specializing in hands on instruction in straw bale construction and finishing, cob, rammed earth, earth bag, passive solar design and adobe.  Glen brings his expertise in natural and solar building techniques, renewable energy system design and installation and a passion and creativity for beautiful, healthy and functional spaces to the Fourth Pig.  When Glen puts down the trowel, saw, bale or wrench, he can be found picking up his two turntables and microphone.


As an architect who designed his own home, I incorporated some tough details, which Glen was able to execute with excellent craftsmanship. This was my first straw bale project and he was a great guide.  I would not hesitate to recommend Glen to my clients.
