HI there! Our exterior siding is Hardi Board concrete siding and the metal wainscot is a corrugated galvalume. Our siding is custom cut for each Studio Shed - so, while you will not be able to find pre-cut panels, you should be able to find Hardi Board at a local hardware store that you can cut and paint yourself. The metal trim and fascia you see around the windows is all custom fabricated in our factory and only available with the purchase of your custom Studio Shed.

Thanks!
