Tziallas Omeara Architecture Studio, Bundaroo House, Bowral

Bundaroo House

Heritage/alterations and additions

A beautiful, sustainable addition to a heritage listed Bowral cottage - one which is private and allows the existing cottage to appear unchanged from the street. The additions maximise the solar-passive performance of the house, create a large entertainers kitchen in the heart of the home.

Boronia House

Alterations and Additions

Significant alterations and additions to an existing residence to create a contemporary family home which maximises views and natural sunlight. The proposal retains the existing footprint and reconfigures the internal layout to create a 5th bedroom, a gym space, and open plan kitchen/living/dining areas.

Oxleys Hill Road

Alterations and Additions

A contemporary, sustainable addition to an existing 1930's dwelling. With the house already commanding a spectacular view over the Bowral town, the new addition was to broaden this view to the south-east and connect the house with the landscape and existing tennis court. Soaring ceilings and a large expanse of thermally-broken glazing allow the occupants to watch the weather roll in from the south, and look down over the early morning blanket of fog which envelopes the town.

As architects for the project at 421-425 Bong Bong Street, Bowral we were asked to produce a design for the site, which is a visually prominent site and at the southern gateway into Bowral. The site itself is not heritage listed, however, the existing building (affectionally known as the “Spare Parts Building” amongst Bowral locals) has a certain presence, and offers a special quality to the Bong Bong streetscape.

Osborne Road

New Build

A new build in Burradoo exploring a pavilion style footprint, with an emphasis on natural light penetrating the whole of the dwelling. The journey through the home was explored, with linking elements separating private and public spaces, and conventional building forms re-imagined in a contemporary build.
