Nail lath strips perpendicular to the joists and lay two battens side by side.

I was thinking about putting more windows in the dormer and extending the roof so there is more overhang (over the dormer and the porch)Another idea was to expand the porch to cover the width of the house, and building a steeper roof on that to hide the ugly dormer behind it (the ridge of the porch roof would run perpendicular to the ridge of the main roof, if that makes sense...)Would love to hear your thoughts or alternatives!

When the duct run needs to go perpendicular to the joists it will obviously need to be flush with the ceiling, but you can place that run alongside a wall.

Hi, I'm looking to purchase a 3 acre property that is at the dead end of and perpendicular to a road maintained by the county. 

Especially for someone new to the game such as my self.On another note... when I’m looking at 305 on a map it seems to run perpendicular to the beach and not parallel.

I agree with Barrington.If you follow those markets you have to expect a dip in prices soon as demand has increased (with a perpendicular chart up) in many areas around the country.

They will be going on the garage which is perpendicular to the house.

Get in the attic and look at your joists, if they run perpendicular it is a good chance it is load bearing.  

If it was mine, I would pull off the roofing and decking and run some 2x2s perpendicular to the rafters to create a pergola.

The range will sit perpendicular to the counter top, forming a right angle in the corner.
