Firstly congratulations on the purchase of your new house. It is wonderful that you are preserving this wonderful building and are so interested in it's history.
You are very fortunate to have the deeds. I agree with Mike, that you should keep them somewhere safe rather than framing them. It would be tempting to do this but I think that framing the documents would not preserve them, and the expose to light would probably damage and fade them over time.
Do some googling for some information about the best way to store them, but I think paper items are usually wrapped in paper. I think it will need to be acid free or you may be able to buy some special archival paper. There were some discussions on rootschat about how to store old documents, so you might like to search for some key words via the [search] box at the top of the page. Perhpas even consider a fire safe box?
Ps. Any chance of seeing a couple of pictures of your house?
