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.

You never mentioned your budget that you're willing to spend. You could add a thicker fill backed insulation blanket - 50mm, 75mm or 100mm are the common thicknesses. Steep roof pitch so would need scaffolding, harnesses, etc.. which adds up quickly. Probably still not enough insulation though but probably cheapest option. Insulation under existing timber linings then reline over the top of that as some have suggested. Working at height though so would need scaffold set up again and working overhead is not fun nor easy. You could replace the roof with a sandwich panel roof. Try Versiclad or Kingspan or comparable. They have a polystyrene type of insulation between an outer metal roof sheet and a metal inner sheet. These are heat laminated together. Again different thickness available from 50mm up to 180mm is common. The 180mm has a R rating of 4.7 which is quite good. Again steep pitch, etc., probably need new ridge capping, etc.. Probably most expensive option...... Keep us all posted on your decision though!

Hi there Victoria, Just trying to add a few more ideas, with a separate Pantry/Landry cupboard (this can easily be ducted and when the doors are closed very quite). Fridge and appliances all along the wall, the island can be what ever size you would prefer. It would also be nice to have a computer desk next to the kitchen by the window. I would also prefer the living area off the sliding doors to the alfresco area Bedroom 4 could have full height sliding doors coming together at the corner this can be close off or left open for times when extra space is needed for the family. And built in Wardrobes in the master would work best, just have something that blends in and looks special.

thank you for your advise. I have put images of the outside of the house as that where the dining room is from there we will be bringing the decking out 3 metres which will create an out - indoor eating. this is the most finished room giving you an idea of the colour and house. all blue grey tones. sorry about stuff around but a reno house is hard to find spaces below is kitchen as is looking out to the dining through that open servery but we are taking most of that wall out to make an open space - its very small step down below into the dining through the left door way. below is the now dining. the table is very small and hard to pull chairs in and out of hence the indoor out door considerations. belwo is the outdoor looking in. from those doors we are putting a 3 metre decking i think. we have a lot of yard so its easy to do
