Annandale House by Welsh + Major stands as a remarkable example of architectural innovation, seamlessly weaving together historical elements with contemporary design within an urban context.

Behind its preserved front rooms, the house navigates a long site with a series of telescoping brick volumes that optimise light, airflow, and functional space, all while respecting Annandale’s historical surrounds. The influence of Welsh + Major’s ethos is evident throughout.

“We describe ourselves as ‘modern-ish’,” says David. “We design contemporary spaces but allow ourselves to be informed by the existing buildings we encounter, always looking for unexpected ways to create beautiful new places to work, live and play.”

The reworked structure included a modest, timber-framed cottage and a dated 1970s rear extension. Now, new masonry forms step down the southern boundary, opening along the north side to maximise sunlight and create expansive, open spaces. The integration of original elements alongside modern additions results in a harmonious dialogue between past and present.

The site’s natural topography, sloping from Nelson Street to a laneway adjacent to Johnsons Creek Park, informed the design. The treescapes from the park are drawn into the interiors through a planted roofscape and curated courtyard plantings, lending the house a sense of openness and connection to its surroundings.

Sustainability was a key consideration, both in design and execution.

“We preserved as much of the existing building as possible, reducing the overall carbon footprint,” says David. “The green roof helps regulate temperature, keeping spaces cool in summer and warm in winter.”

“A retractable glass roof enhances ventilation, creating a natural thermal current and bringing sunlight into the home’s core. A water tank beneath the house captures rainwater for use in the toilets, laundry, and garden.”

The interior palette of raw concrete, recycled brick, and fine timber finishes provides a tactile and visually engaging contrast. Sliding glass doors and louvres enhance natural airflow, while the upper-level master bedroom enjoys sweeping elevated views.

The play of light and space throughout the home is both timeless and innovative, blending impressive design cues with architectural integrity and purpose.

“My favourite part is the sunlit living area with its two-storey atrium housing a beautiful tree,” says David. “The sculptured stair, topped with the retractable glass roof, provides access to the outdoors, creating a dynamic space that adapts to Sydney’s climate.”

“This design makes the most of its premier location, showcasing how even a small site can become a generous, expansive place to live.”
