Merri Creek House

Set along the bushland edge of Merri Creek in Northcote, Merri Creek House is a renovation by Breathe Architecture that builds on an existing 1990s residence originally designed by Goad Fink and later extended by Fink & McMahon. Rather than reworking the house through expansion, the project adopts a strategy of adaptation, using targeted interventions to improve environmental performance, spatial clarity, and long-term usability while retaining the character of the original design. Tom Ross   Reuse and continuity as design drivers A key sustainability move lies in the decision to retain and extend the existing building fabric. The project avoids large-scale demolition, preserving the embodied energy of the original structur... More

Family Treehouse

The Family Tree House is a set of architectural interventions grafted onto a remnant coastal character house.  There is a family lineage to the house, it has been our Client’s Grandmother’s place and in turn his mother’s home. At its core was a humble one-bedroom hardwood framed cottage with an enclosed verandah wrapping along its eastern and northern edges. Accompanying and protecting the house is a colossal Weeping Fig planted generations ago, it has been climbed by our Client and his siblings as children and his own 3 boys whilst the family gathered beneath its boughs in the coolth of its shade. Christopher Frederick Jones Our site strategy is one of respect and retention, with the architecture aspiring to c... More

ATTIC HOUSE

A large block in the Northern suburbs of Melbourne with a house crying out to be loved again. This project was to transform a dark and claustrophobic home into a breath of light filled openness. Maria Savelieva Maria Savelieva The design balances the need for private and communal areas by allocating distinct zones to each level. The front entry boasts large bedrooms with lots of storage space, generous family bathroom and ensuite, an additional Rumpus room and bedroom cleverly tucked away n the attic space.

Birch Tree House

Birch Tree House is a thoughtful addition to an early-twentieth-century brick terrace house, located in the Maastricht suburb of Sint Pieter. This tiny little project has been a labour of love for me, which started when my client, Jasper, asked me to design a low-budget addition to their home. Caption The projects aim was to create a better connection between the house and its small rear garden and to introduce a sense of light into the house. The design was conceived as a 'garden room' sitting gently between house and garden. Caption To make this tiny addition feel generous and spatious, a couple of spatial tools were used. The most important one being the dramatic change in ceiling height - also known as "compressing and relea... More

Henry House

Henry House is a 140-year-old Victorian terrace house that has been refurbished and extended with a contemporary rear ground level extension. This Victorian is one of a pair of double-storey, single-fronted terraces that was originally built in 1878, and is part of the rich history of buildings that line this street in East Melbourne. The house had undergone an earlier renovation by the previous tenants that widened the footprint of the rear ground level rooms to take advantage of the full width of the narrow site. However this earlier renovation still lacked a strong connection with the backyard which had succumbed to overgrowth over time.  The current owners wanted the rear to open up to the garden and have a functional outdoor liv...

Malvern Garden House

Malvern Garden House is a highly-considered adaption of an existing 1930’s period home in a hilly suburban pocket, with a new pavilion embedded within the terraced garden to the rear. Most fundamentally, the design response seeks to actively reposition the home within its unique site, thereby strengthening and celebrating the bonds of the everyday architectural experience within its immediate, lived-in landscape. Derek Swalwell Period homes are often typified by disparate, compartmentalised spaces, lacking vital connection to the outdoors. To this end, the original dwelling presented the familiar challenge of reworking a robust, but out-dated home, no longer conducive to the contemporary lifestyle and aspirations of its inhabita...

Lilyfield House

WANGAL COUNTRY. Lilyfield House is an inner city home, conceived as a spatial assembly of internal and external rooms and volumes, opening to the light, to green spaces and rising to the district outlook. The rooms and platforms of the house pivot around a central atrium, integrating portions of a historic shop. Accessible from only two sides and subject to acoustic constraints under a flight path, these 3-storey alterations and additions cater for family living and working from home. A reduced materials palette of off-form concrete, black steel, plywood and bamboo flooring and historic fabric in white-set plaster, provides a generosity of space and light for a family of five. Lilyfield House is effcient in its use of an inner city site.... More

Blinker House (Hunters Hill House)

The Blinker House is located within a heritage conservation area within the suburb of Hunters Hill, close to the centre of Sydney. The site and surrounding properties are typically freestanding homes on medium and larger sized garden blocks. The existing house is an exceptional example of an Australian period home circa 1927. A 1980’s renovation existed to the rear of the house which did not fit the current owner’s requirements and expectations of family moving into the future. The primary brief was to create a more modern, open plan layout to the rear with some modification to the existing internal bedrooms to the front. The neighbouring home has a position so that the entertainment area backs directly onto the rear of the subject property... More
