Overshadowing concerns from the neighbouring Phoenix Apartments in Braddon have not altered plans for a nine-storey mixed-use development that will add a further 105 apartments to the Northbourne corridor.

Canberra-based property group Liebke and Co have lodged a development application for the project to be built on a 2090 square metre rectangular site at 90 Northbourne Avenue in Braddon (Block 1 Section 19).

The pre-DA consultation report said the loss of sunlight was the main concern from residents in 38 north-facing units in the Phoenix Apartments, with many wanting the developer to reconsider the building height or design.

The proponent acknowledges that the building will reduce the amount of sunlight the Phoenix will receive, especially within the winter months, but believes the proposal is still within the planning rules, saying the affected in the adjoining block will receive more than two hours of direct sunlight between 9 am and 4 pm for many days of the year, as required.

The DA says this is considered reasonable given the short five-metre setback northern boundary and the constrained nature of the subject block.

Any reduction in building height or change to the design redesigns will affect the viability of the project, given the purchase value of the site and its small size, the DA prepared by Purdon Planning says.
