The block dimensions are approximately 15.23m wide by 70m long with a fall of just over 8m.
There is a sewer line and an easement running directly through the middle of the block, between both side boundaries.
Careful consideration of the neighbouring properties was taken into account, especially during the design phase.
Upon investigation of the exisiting residence, due to the severity of the sloping driveway, exisiting concrete piles were found along the eastern and western boundaries.
The starting point of the design was creating street level access to the garage and entry.
This meant demolishing the existing garage and porch stairs at the bottom of the driveway.
Due to council regulations and height constraints, the lift shaft in its final location was as far south (towards the river) as was permitted.
In order to maintain external access to the pool, external staircases had to be allowed for – one at street level along the western boundary, and, due to the steepness of the block and taking into account the excavation restraints, the other orientated inwards.
The arrangement presented an opportunity to create a point of interest at the entry level, in the form of a sunken courtyard.
This sunken courtyard not only provided access between external staircases, but also the opportunity for ventilation and natural light to the rooms located on the middle floor.
Utilising the external staircase from the street, and the sunken courtyard, this seemed the most logical location for the self-contained au-pair/guest bedroom so guests can come and go as pleased.
