You might consider corrugated steel.

Personally I find the overall composition quite interesting and it could get too busy if you introduce another material. Do you have a close-up of the building showing how the materials come together ?

I have to agree with Dytecture I love the low slung look that the house has. I would flip to own that home.

Hi Mark,

Dytecture is spot-on. The home is visually interesting enough and doesnt need a third element. Great design btw.

Love this house just as it is! It reads very masculine to me, all hard edges.The most budget friendly additions would be creative use of color on the exterior, and perhaps fanciful or whimsical hardscape/landscape elements, so the architecture doesn't take itself too seriously and creates a bit of softness.

This is an incredible design. The lines are perfect. I will say that my eye is drawn to the expanses of the gray. And, maybe, there is just a little too much of it. I would add the same wood feature to the portion of gray in front of the higher middle piece. I would then continue it to the right on the gray portion to the end..BUT using the width of the side support in gray, I would continue that gray width below the wood. In other words, use the width of the side support (maybe it's a foot) continue it up and to the left along the bottom of where it is now. From the top use the wood design down to the portion left gray. This would be a Photoshop idea.

I agree with Dytecture and Interiors International, Inc. the building looks good a few edits and experiments with materials and coloring can get this design to shine. The house looks good.

Thanks for your inputs, I think you're right, less is more.
