Sustainable Building Services 


Erkhart Construction has extensive experience in sustainable building techniques and systems. We are constantly researching new methods to reduce our impact on the environment further, making our homes a safer and healthier place to live, work, and play. We offer sustainable materials such as hempcrete, strawbale and recycled timber when building your passive home to ensure that it's as eco-friendly as possible. 




Hempcrete is a sustainable and environmentally conscious option for building homes. Hempcrete is a bio-composite material, a mixture of hemp hurds (shives) and lime, used as a material for construction and insulation.

Hempcrete is easier to work with than traditional lime mixes s it acts as an insulator and moisture regulator. The result is a lightweight, sustainable material that combines insulation and thermal mass. Research suggests that hempcrete is the building material for the future. 



There is nothing quite like the feeling of walking into a strawbale home. Thick and well-insulated walls, soft curves of the plaster create a warm and inviting space. Receiving the opportunity to work with this beautiful, natural product is a joy of ours, and if it's a dream of yours, we'd love to discuss your options with you.​


Recycled Timber

Working with timber is soul food for the team at Erkhart Construction. As carpenters, first and foremost, nothing gives us more pleasure and joy than bringing an old piece of wood back to life. If it's time to unearth that beautiful old stash of timber, it would be our pleasure to give it a new lease of life by incorporating it into your new home.
