Hi David

It's hard to say without looking at the site properly.  If there is no demolition control then Council shouldn't really worry about removing the old house.  However, it does depend on what other dwellings are around the area, so you may have to use certain materials in construction.

I think the last option of 4 new townhouses on individual lots i.e. devide the block into quaters sounds the best initally.

I know a town planner at BCC so if you want to let me know the address I can get them to have a quick look at what options the council might prefer.

Obviously, your best bet is to consult a Planner yourself as they have probably seen this type of block before.  It might be worth looking at RiskSmart approved Planners etc, (if you haven't already) as the size of your development may qualify for this and will ensure a much faster DA approval time!

you can e-mail me at [email protected] if you prefer.

Cheers

Brendan
