A substantial lower ground room is inserted under the original fabric, harnessing the fall in the site towards the rear. It extends deeply beneath the existing dwelling and outwards towards the garden to transform the original dwelling in combination with the re-crafted rear of the ground floor above.
Both levels accept a modestly-sized lightweight addition which extrapolates existing wall alignments, gutter levels and enclosing wall heights - that at once, extends and subverts existing geometries to present an interpreted mirrored slice of the original vernacular form and palette attached to the retained rear fabric. An eccentric roof form extrapolates the original southern roof plane to mitigate adjacent impacts - lifting to light and tree views to the east, while also folding upwards for access to northern light and sky through a sole fire-rated window along the boundary.
The project retains its original envelope and significant portion of its
ground floor fabric as part of its overriding environmental and economic sustainability
objectives. New work is substantially embedded within the existing footprint,
with only a modestly-sized 20sqm addition to the rear. Vaulted
ceilings and skylights carved within the original roof form expand volumes for access
to light and sky within the middle of the ground floor - while a stair hall,
cantilevered balcony and generous void spatially expands to the lower level
below, and upwards to views of the external environment to strengthen
connections to its setting. Fenestration placement improves natural light access and promotes passive
ventilation, assisted by ceiling fans and a roof venting system to exhaust
trapped heat out of the original roof space.

Testimonial: Georgina Cosgriff
We engaged Christopher Polly Architect to design and manage the renovation of our two bedroom home. Chris had a positive “can-do” attitude and an extremely creative vision. He made full use of our sloping site to create a wonderful four bedroom family home which accommodated council’s strict development controls.
Chris was also able to incorporate our love of the garden and, in particular, a huge jacaranda tree into the design. Chris has a very professional attitude and his thoroughness in the design process meant that we had very little difficulty during the DA stage.
Chris also managed the build and ensured that the finished project met his high expectations. Chris is attentive and very open with communication. We would have no hesitation in recommending Christopher Polly Architect.
