Hipped dormer for William and Mary dollhouse

I have four hipped dormers to make for the William and Mary dolls' house, and I started with the one in the kitchen roof.  I'll do a proper tutorial on hipped dormers when I do the three on the main house, but here's a walk through.  

Here's my reference photo:

Based on this photo, I chose the Housework's working casement window.  I painted the window white and added the panes using 1/32" vinyl model striping.  Then I built my dormer from foam core, because it's light and easy to adjust.  I glued and then duct taped the dormer together.

I drew the outline of the dormer unit on the backing, and cut out the opening.

I glued the dormer to the backing panel over the hole, and used narrow strips of aluminium tape (used for duct work) to mimic lead.  I slated the dormer with Richard Stacey Versi Slates, using folded slates as ridge tiles.  Then I started slating the roof, making sure that the backing panel for the dormer would lift free of the roof base, so I have access to the little room underneath.

I've run out of slates, so have to wait for my shipment, but I'm very pleased with this first attempt!
