There are hundreds of suggestions that can be made on how to update, renovate and re-design a layout to make it functional for you and allow it to respond well to the built environment. Engaging an architect or building designer at this stage may not be something you're willing to do, as spending money for plans on a house you don't own would not be the ideal situation. The issue with this is that the design phase of a project takes a lot of time and consideration. My best advice would be to play around with the plans and create some sketches, whether online or on paper. If you are happy with the possibilities then buy the property. Any house can be transformed, but whether or not you are satisfied with the transformation is a personal choice only you can make.

I've been playing around with a pantry location. Originally, I was going to move the pantry into the laundry with some custom shelving and cut the laundry space in half. Now, Im thinking of cutting into the study area and building a wall there, and converting the new space into a long and narrow walk in pantry. Either that or build half a wall and put built in shelving in the study. Building the extra wall will reduce the need to cover in the door way that is currently in place and instead utilising it. Thoughts? p.s. this isnt too scale.

This floor plan has a single garage, with bedrooms grouped together at the front of the house, the Music Room has been moved to the rear away from the bedrooms as it would make too much noise for those sleeping. It can now be opened up to the family kitchen dining, courtyard and Alfresco and can be used as a play room(/ guest room) giving children great indoor out door play area in view of parents. There's a study with a similar view. A powder room closer to the rear of the house for easy access, The main bathroom is done Japanese style. The master suite has the WIR between the bed and the ensuite, no noise etc when in use to disturb anyone. I have made the passage way extra wide and more like a room which has a linen cupboard, you could certainly make this narrower and add to the bedrooms if you wished, This comes to 204.5 sq m. cheers

siriuskey, Yes, the courtyard is open to the sky (no roof over it), I assume this is what you mean by double story. Ref. below photos, I would love to get this look, especially the first and last photo, where you can see family living space from the first floor. I can't achieve this in my plan as it eats a lot of floor space upstairs. The referred plan (photos) has a very big void combining staircase, hallway and dining area. I know it is not easy with cooling and heating when you have such a big void. So, I explored a few ideas (with my limited knowledge on this topic) before achieving the current floorplan. I have also thought about, in my current plan, extending the void on the staircase to the dining area (it is more like L shape) but i wasn't sure if that makes any difference. keen to hear your thoughts.
