Hmm.. wonder if the backplates are brass. Bru - I was going to attempt to put them on myself. DH will probably get involved. Neither one of use have put a door knob on though before. My Dad's pretty skilled with stuff like this but he had back surgery last week and I'm sure isn't feeling up to working on it. The knobs should at least fit right? The ones on my door are 2" diameter and I'm pretty sure these are too.

Thank you I'll check out the pewter. I'm not just going based on the range, I have a large (really large lol) collection of mid-century kitchen accessories that I plan to display in the kitchen/breakfast area. Many of these are shiny chrome, think Sunbeam mixers and metal canisters. I also have a lot of pink and turquoise dishes, colored milk glass and other pastel kitchsy kitchen stuff. Outside of the kitchen and bathrooms I favor more transitional decor, not modern or glam by any means. I do like some vintage/antique elements. I have several pieces of Victorian furniture in my living room and entry currently that I plan to use in the new house. My style is a a little eclectic, anything from about 1890-1960 and I like it ;) This post was more regarding door knobs but overall I have a bit of a design dilemma to make everything cohesive. At this point I'm trying to choose a good foundation to decorate around and I think I have done that in everything but the hardware finishes. Now I feel like I need to keep thinking. Thanks for your help Jan.

There are interior doors made for sound reduction, they have STC ratings and there are exterior doors that have STC ratings you could compare the numbers to each and compare them to your wall assembly and see what would work. 1 3/8 interior doors can have a better STC rating than The wall. You could retrofit a wood threshold to the existing door to close the gap at the bottom or just lower the door assembly if it is on carpet and use the carpet as a friction fit . If your dead set on on an exterior door you remove the threshold , cut it down and modify if with wood and also shorten the width, you could remove the aluminum sill, cut the frame down and put a lower profile sill in or let the weatherstripping graze the floor.. If you like the aluminum sill just replace your flooring with aluminum flooring to match the threshold. There are many options but lack of details to help assist.

IMO the exterior and the interior do not need to match is anyway. But you might find it difficult to get the mix you want for the exterior door.
