Thank you Snoozee and IceEyez for your valuable advice.
1) In this scenario regarding the shifting of the gate, if the width of the land is 11.4m long, and I have to set 6m away from my neighbour’s gate on my right and also 2m from the boundary line on my left , does this mean I can essentially shift my gate and do up a gate that’s max 3.4m in width?
I have also purchased the BCA plan, SIP, DIP and RLP. Except from having a surveyor or PE to come down, can I safely assume that it’s highly probable that I will be able to shift my gate?
2) Regarding the rebuilding aspects, can I safely assume $350psf including miscellaneous costs such as fees for the PE, Surveyor, soil test etc? Any idea what typically forms the main bulk of costs for rebuilding? For example, the main structure or carpentry? Or Electrical and Plumbing? I have read that $350psf for rebuild is for a mid range build. Can I understand that it means by mid range? For example, parquet instead of marble? Or bricks instead of concrete?
3) For a land size of 3800 sqft, based on your experience, is it recommended to look at having 2 buildings separated by maybe a quiet garden or patio that is about 10m in length? Width of land is about 11.4m and Length of land is about 33m. I understand that an architect can give a better representation of the rebuild and I just wanted to gather from fellow contributors in the forum.
