The siding is almost fully up on the Narrow Passive House! We specified pre-finished siding products, which have many benefits including extra durability. Another benefit which home owners appreciate is how quickly pre-finished products are installed. Once the siding is installed the house starts to look like their house from the design drawings, which is a really exciting time. We used a pre-finished fiber cement panel siding with aluminum trim, cedar siding pre-stained with a locally made non-toxic stain, and factory-finished horizontal ribbed steel siding.
