A ring beam lacking in previous houses was added to hold the structure together.

In some projects an additional ring beam is used on the top. The process enabled building awareness and local capacity on these resilient construction techniques. Typically the roof beam is made by nailing together a few pieces of dimensional lumber. The pitch of the toof is significantly increased to provide additional strength and durability as well as providing a better internal space.

Ring beams are a type of support used in construction to connect walls together and increase the load capacity for the walls.
