Hands-on at Deep Green Building 2018

Palace at Naklo Attic

Participants will help construct walls for a guest room in the attic of HempToday Center.

(Afternoons & Evenings/Days 1, 2 & 3) The hands-on project for this course is the construction of interior walls (remember, it’s February!) to create a guest room in the attic of the Palace at Nakło, an 18th century estate that serves as the home of HempToday Center and a functioning Hemp Bed & Breakfast.

This unique initiative is based on an architectural plan to add five rooms and an apartment in open space that, through nearly 250 years, was never inhabited. Hemp-lime is the perfect construction material for this project based on its light weight, and its advantageous thermal and acoustical properties. It also results in walls that are stronger than those used in traditional construction, and provide natural humidity and thermal control – all in one layer. In essence, these materials breathe.
