Presumably there has been explanation and justification for what has been provided so far? Corner plots can be tricky - you will need a design that 'turns the corner' successfully and mediates the shift from bungalow to two storey, without appearing over-bearing. Aside from impact on the overall streetscape there may be constraints around impact on neighbour's amenity / light etc. The local residential design guide (planning spd) could be worth a look for general council expectations. Once you have drawings (you are happy with) do a pre-app to test the water on your maximum preferred option - on the basis that you have a backup option to scale down to if the guidance requires it.
