to me location is not about the site layout but where is it (which town, which taman, which road). which in this case doesn't matter as you already sure of buying in that location.
what you are refering to is site layout, precinct plan and land form and orientation.
very difficult to say from just the site plan. btw your plot size is indeed 18x60 for typical intermediate, it is a small DST (my estimate, probably 18x30 base floor area for the house with about 30 ft porch) and affordable type.
fyi, i normally concerned if a house is next to a road (even auxiliary), what kind of traffic you expecting, is there a perimeter fence. next to shop lot across the road, what kind of business may open there, will there be a lot of people parking their car in front your house to walk to the shoplot, your lot 127 the side of the house is facing west? will it be very hot? how about land form, is there slope, if so how is the slope (if water can flow into your front porch for eg...) so there are many factor.
if u ask me to choose and got choices, i would prefer lot 114, 82, 51 around there. but your lot 127 is larger.
but congrats to change your name to corner lot, i think should be worth it. the typical int terrace is 18x60, house and plot is rather small, now at least you have extra 20 ft width land at the side , so overall i think you won't regret your choice to upgrade from inter to corner.
Thanks. Very useful. I read them all. Thanks for your advise
