I'm hopeful that a pro will provide you with some great ideas. Yours looks like some of the "befores" that they do brilliant changes to on the TV reno shows. Most architects will come up with excellent solutions within the space if that's what's required, but nothing worthwhile is likely to be done cheaply though.

Hi Sien, frequently tiles are built up covering either original stone hearth and/or concrete bases required to keep the fire away from timber so you need to figure out: a) Do you want to keep some sort of a fireplace b) Will it be functional and what kind of fuel do you want to use c) Are you prepared to put the work in on maintaining a traditional fireplace with wood fuel (lots of work - dirty, unpleasant work and chimney sweeping) or the cleaner gas/electric options. I don't think you need an interior designer - you can do it yourself - do your homework and talk to local fireplace retail specialists in your area so that you're making informed choices - this will help you decide what to pull out, what to keep, what to install. Then you can call in a fireplace maintenance expert (sweep and flue services) either to clean out your fireplace prior to pulling it out (stops more dirt/dust/soot from flying around your home then absolutely necessary) or doing the maintenance on it.

Depends on what you are planning to do with the room whether to paint or not, both mantels are missing their inserts. The first photo does look like it's two pieces, the top is Art Nouvea , the second timber mantel looks Art Decco. For me the first photo with fire place I would look into a gas insert to fit, not sure whats on offer, but similar size as how to girl, you can get plain metal fireplace inserts with out tiles. You could use either mantels but I think I'd find another use for the separate mirror, perhaps over a side board cheers

The simple whites are what I like, the lounge welcomes you to get comfortable and spend time and lose all the distractions, giving you a chance to refresh and refocus. The TV art on the wall is the highlight and draws your attention, and hides its personalities. Is it a TV at all?, Overall I chose number 9 for its simplicity and comforting feel with no clutter and with one piece to comfort the body and one piece to stimulate the mind.
