Construction Timeline

Relying on BONE Structure’s integrated services can significantly speed up the construction process: our architectural design, interior design, engineering and project management teams all work in tandem to seamlessly advance your project. Here are the first steps of a typical timeline, for a custom home built in California.

Fire Resistance

BONE Structure homes are built with a patented steel structure system, and insulated with a combination of rigid and spray foam insulation. Several design features of BONE Structure homes provide fire resistance advantages, and can help reduce the risk of fire.


Steel, the main structural component in BONE Structure homes, is a non-combustible material. It therefore does not burn, nor does it provide an ignition source or add fuel load that would enable a fire to spread or grow.


BONE Structure Homes are designed with unventilated attics. The shell is closed all the way to the top layer, with no access to the roof structure from the outside. This reduces the risk of fire propagating via flying embers, a very common occurrence in wildfires.


BONE Structure Homes can be equipped with high performance triple pane windows which resist heat and prevent fire propagation much more efficiently than single or double pane windows.


Closed Cell Spray Foam is used in the walls and roof of a BONE Structure Home. Contrary to popular belief, Spray Foam does not melt but instead creates a char layer protecting from further fire propagation.
