There are panels that you can install from the manufacturer...I suppose you checked those out...

I do love that little door though :)

did you already put it in the wall? Put it in a storm door and use your regular door to close and lock.

Oh, that little door is just precious.

I hate precious.

There is no way to put in a storm door. Here is the House Blueprint - my only available option is to put it on a dining room wall, by the sliding glass door.

You can have a dog door installed in your dining room sliding glass door. It requires replacing one glass panel with special glass and a glass shop that is willing to measure the door size, dog door size, order & install it for you. You would need to goggle in-glass dog doors. Many offer locks on the panel or a transmitter worn by the dog that opens the flap. The manufacturer gave us a list of glass shops in our area. We stored our original panel in case we ever wanted to take out the dog door.

The little door is cute! And I like the little coat hook for the doggie coat!

Since you're building a house, you should have left over materials to make the door and frame. Plus, whoever is installing your doors and cabinets would be able to help you make this.

If that's not the case, then you can buy the 'frame' pieces at Home Depot or Lowes by shopping in the lumber, finished-wood-moulding section. Have them cut the three pieces in the lengths you need, then buy the 2 squares for the corners. Also make sure the frame is the same depth (or deeper) as the door+trim so it's flush when it closes. You'll need to cut out sections of your baseboard, or another option is to butt the vertical pieces on top of the baseboard. For the door, decide on size and the type wood (or mdf) that you want to use and buy moulding strips to make the panels. Caulk all the seams and then paint.

BTW, with the knob, knocker, and panel trim.....there's no way that little door is closing against the dog door.

If you take that photo to the lumber store they can help you figure out what you need. Have your measurements ready to show them.

Love the knocker. That way the door won't get damaged when the scratch to be let in as most dogs do.

Love the door sample you posted. Here are two great options that I found for you on Etsy, both priced pretty reasonably IMO.
