Congrats , and your place is nice and has some character ! I'd suggest moving in and living there for at least 6 months before you do anything , but by the sounds of it , the view out the right hand side of the kitchen is really nice ? To my thinking , you'd be better to make that the dining area , go with a bigger kitchen than present but only half the 'huge' option , and have a study area as part of the lounge . Having the dining where it is shown would be darker , but also in the middle of where the natural flow is -- better to have a desk and bookcase against a wall , compared to a dining table and 6 chairs IMO . One thing that confuses me is the photo that looks like a lounge -- the last photo . There are windows on 2 sides , and it doesn't look to be 'in the middle' of the house -- doesn't seem to tie in with the floorplan ?

If your tv is 65” then the lounge is way too close to television. Place lounge as per my diagram. Two lounges in L shape plus single chair. If you remove the small wall then dining table can be across room. But it may be load bearing, so unable to be removed.

@dreamer : That's exactly what it is, kitchenette - handy for drinks of water, making tea/coffee. We had a undermount sink there instead of vanity bowl, but the cabinet and stone was already cut which restricted use of undermount sink. We are happy with current setting of vanity bowl and pullout mixer. FYI....there are already two bathrooms upstairs ( 2separate basin inside them) so no need to run downstairs :) . @kate Sure, please allow me a day to visit site and do the actual measurements. Will share it here soon. . Actually, my partner and both work from home most of time and we have one dedicated study/office room which one of us will use. But we are looking to see another place where we can setup a office table/chair or some sort of study nook. House is built as per the plans (ground floor is here). Could you suggest another place where we can setup a office table/chair or some sort of study nook as we were thinking to put somewhere in rumpus area as I mentioned in the first post of this thread.

Ask yourself is the has in a good neighbourhood with good outlook. Stamp duty and moving costs are not cheap. Can u in future extend out back behind study for new master suite? Back to your plans. Servery windows are expensive for the gain/. Opt 2 has better access from kitchen to deck as no peninsular to walk around
