Additional Information + faq
-
The Hempstead Living house plans are meant to serve as a streamlined process for building a hempcrete home; utilizing a pre-designed house plan eliminates a large amount of both time and money from the pre-design process. We can make minor revisions to any of the Hempstead house plans shown here. Minor revisions are defined as any internal changes; any change which requires moving the exterior walls, the roof, or the floor system results in custom changes; all custom changes can be administered through one of our partner companies.
-
All building permits are granted through your local building and zoning departments; each municipality may have their own specific requirements. We offer a complete and comprehensive amount of documentation, but we ALWAYS recommend meeting with your local building department first, to understand what they will require for permit approval. It is possible that they may require an architect's stamp, structural engineering, or other specific requirements. Always check with your local jurisdiction first.

APRIL MAGILL
April is a leading voice in the advancement of alternative, climate-smart & healthy building methods and has been a pioneer in the southeast. She is an Architect, small business owner, Executive Director, and Adjunct Professor; April has been a keynote speaker and presenter to many organizations and universities over the past decade.
April has been a Charleston County resident since 2004 and has devoted her career to the advancement of sustainable architecture and affordable housing. After advancing her career at several Charleston architecture firms, in 2011 she took a leap of faith and founded Root Down Designs, a women-led architecture firm dedicated to sustainable architecture and affordable housing in the south where she serves as the Principal Architect. April pioneered several carbon-negative and alternative housing prototypes in Charleston, such as a Rammed-Earth home and Compressed Earth Blocks. She has worked with multiple building jurisdictions in helping clients obtain building permits for alternative materials and healthy housing. Working with financially-challenged clients and creating affordable building options has been a strong tenant of the Root Down team.
As a way to educate about these healthy and natural building materials, she began teaching building workshops with a ‘community-building’ ethos embedded. April has led over 4 dozen community-building workshops and courses across the southeast, including educational institutions such as Greenville Technical College, The Governor’s School of Science & Math, and the American College of Building Arts. Her passion for sustainable architecture and community-building workshops was noticed by The American College of the Building Arts, and she began serving as the Professor of Sustainable Materials in 2018.
