Thank you both very much. You've both put a lot of thought and effort into this, its much appreciated! Its definitely opened up my thoughts and ideas on the space! Its definitely not as daunting as I was thinking and it is do-able! When you look at it everyday you get a bit stuck. I guess I need to weigh up making that study space smaller. It then makes the house technically 3B 2B. But I'm going to have to compromise somewhere for this to work! Its nice to have something tangible and clear to show the builders, so thank you! I might start drawing up something that's a little of both, as I love aspects of both designs. :)

the first variation feels very cramped and number 2 is more comfortable but, given enough space, you could consider another option and adding furniture helps understand the spaces better but maybe the bed would be better along the back wall so that you could have a view to the deck from in bed..but that could mean rethinking that extra window ..perhaps a tall narrow window behind the chair? (nb dimensions are only guestimated and the plan suggests that a liitle extra could be taken off the bedroom to make the ens and wiw wider to allow for bigger bath and/or wider and/or twin handbasins)

Wow Nicole, sorry you took my offer of assistance the wrong way. I responded as there had been no other responses to this original posting from 18th January, and your plans and the original question didn't show great clarity of thinking. I am glad that you have resolved your queries via another posting, drawn everything up yourself to a high standard so that your renovation will progress smoothly and efficiently with all of the appropriate technical documentation. Fortunately, with my six years contributing to the Houzz community and my 66 Houzz reviews, I know that not everybody thinks as you do. Best of luck with your renovation, Dr Retro

Wow, thanks oklouise, that is already way better than anything I could come up with! I will attach another couple of photos that should have all the dimensions for you and full copy of the floor plan. And Liz, I agree it is tricky. I have literally spent hours looking at it shaking my head! To answer your questions… yes, the house is on a slab, we are a family of 5, no space can be taken from other rooms (we are full!), not so sure of budget as depends on ideas, view from bay windows is beautiful, bed is king size and currently goes on the same wall as the toilet and is probably best there for views etc. we have even thought of putting in another window on that wall to go above the bed because the view out of the current ensuite window is nice too. Hope that helps! Thanks so much for the ideas. Amazing.
