The walls are board form concrete. The wood grain leaves an imprint. Looks like wood but it's concrete. Natural color. The house has the same construction design for major walls exactly the same as the landscape walls.

a.d.d, concept and design,

does board form concrete imply that the walls are solid concrete like a foundation pour? I noticed on one of the interior kitchen photos and outlet in the concrete wall; so I suppose that was planned or cut later? Curious if this is formed over a framed wall or if these walls are indeed solid? Thanks, inspiring design and textures.

These walls are solid structural concrete walls. All electrical and plumbing are planned in advanced with proper tubing and conduit piping put in place. You can not do it after the fact.

Little room for error... it is a beautiful look.

Hope that helps... Structural Engineering is a must and a great GC is needed!
