SUD on LMR unusually shaped 800m2 block in Brisbane Suburb

Looking at doing an SUD on 800m2 (on 2 lots – separate titles) – LMR zoning (50% GFA) – 25 metre frontage (across both lots – 12.5m each) – with an existing old house well loacted to the front and side of one of the lots.

I can either do a subdivision of the lots into 2 titles and reno/or remove the house and build 1 house or 2 houses.

However – my calculations point towards an "SUD" of the 1 title being more profitable than a subdivision.

2 QUESTIONS FOR ANYONE FAMILIAR WITH SUD DEVELOPMENTS IN BRISBANE:

1): Given that the frontage of the block is 25 metres wide and 33 metres deep – rather than your standard LMR sized block with 17m frontage – is this going to have an impact on the number of houses/townhouses able to be built ? (If it were 800m2 with a normal 17m frontage with small house at front/side – you would be able to place 3 townhouses at the rear of the house). Given the width of this frontage – I'd like to build one at the front next to existing house and 2 at the rear with common driveway down the middle.

2): The existing house though in a great position on block – is in terrible condition and potentially unlivable and not able to be saved with a reno.
Given that the council originally conceptualized the "SUD" code to allow existing historical houses to remain without demolition while still allowing new development on same block – would they still allow me to do an "SUD" if i demolished and removed the existing house (post war/no demo zoning) and replaced with a removable house in better condition or built a new house – then did the new developments next to and behind this house ?

Or – removed the house and just replaced with 4 new houses/townhouses (narrow ones to fit 2 on the front and 2 at rear with driveway down the middle) ?

I know this is a little tricky, however for someone in the know and with specific experience in SUD's – perhaps its a simple answer/solution.

Obviously I'll engage a planning consultant to work on the DA, however – I hope to get a good idea of what I can do and potential profitability before engaging a planner and designer to really get into the nitty gritty

Hope someone may be able to assist.

Cheers,

David.
