:: screened porches & fireplaces

So, Thanksgiving is a week away, and all I can think about are screened porches & fireplaces.
Our new house has a lovely little screened porch which is one of the things that attracted me to my home in the first place. However, after spending some time on it this summer we realized we would like it to be a bit larger to accommodate more friends & family at one time. Currently it's about 11' x 12', and our plan is to rebuild it to 18' x 20' and some odd inches. Needless to say, I've been doing lots of research trying to figure out how I want it to look ultimately. One thing is for certain though & that is a fireplace. I love the look & I'm looking forward to being able to use the porch well beyond summer.
The photo above is pretty much what I'm going for, isn't it gorgeous. It's really amazing how expensive all the little details are. Right now I'm trying to decide just how worth it the details are to me. Currently I'm trying to pick out the stone or brick for the fireplace and some sort of flooring either cypress like the image above or a herringbone brick.
So, what are your thoughts? Pull out all the detail stops, or keep it simple & cost effective?
This is my first time with any kind of construction or home additions so any advice on the subject would be greatly appreciated.
Below are a few more of my inspiration images, they can all be found on my pinterest board here

loving the look of this painted brick fireplace.

The stone and the arched opening are quite nice though I do want a mantle.

Which look do you prefer.... Stone or Brick?
Decisions....Decisions.....Decisions.... Goodness, it may be next year before we get this done if I have to decide.
