Thanks, yes we have and found great tiles but are just concerned it will look " messy" !!

thanks to everyone for your helpful comments! I was going to have to pay around $190 for 6 more, but will order them from Beaumont who have a 25% sale on at the moment. I agree that I need to just live with the cost and finish the job properly, but your shortcut suggestions were all really interesting and much appreciated. And archimondo, I'd say it's like having a kangaroo loose in the top paddock.

Thanks for the measurements, there were a few missing that would have made it easier to be more precise, But I'am making suggestions on what I think might fit within the existing floor plan which you are trying to do. the only small extension is to fit the laundry into a shared family bathroom. As there is already a shower and toilet in the current laundry I think it would be wrong to move them as they are close to your new alfresco area for the family to have easy access when you have your get togethers. To try and keep the girls bedrooms a good size and together with the other two bedrooms I suggest working with the fireplace and making the current Bathroom and ensuite but with the ability to share the toilet with the girls during the night. I have added my beloved barn doors to close off the kitchen from the bedrooms and also to be able to leave open during the day for extra light., the planned deck with roof over will make the dining/study/kitchen darker so you might need to consider a sky light. Anyway just a few different ideas trying to work with and around special features cheers

how old is the house as you may need to check for asbestos on walls and floor and is teh whole house a slab on ground if not the floor under the tiles may not be concrete..., when replacing floor tiles i would also replace skirts to ensure waterproofing is above the floor all around (and avoid a potential leak at the join) and depending on what you are planning to do (ëg install new shower stall or wet floor?) i would also consult your tiler about "levelling the floor" which is much more complicated than we think.. and take your time removing the old tiles, especially on the walls as it's better to do as little damage (to the structure and yourself) as possible and you will find many online DIY instructions for retiling that are worth reading before you start...good luck with your project
