The streets of Paddington in Sydney are framed by Victorian-era homes, their facades adorned with intricate iron lacework and classical decorative details. Yet behind these heritage exteriors, surprises await. Once dark and closed off from their surroundings, many of these residences have been reimagined, transformed into bright, open spaces designed for modern living
The Paddington St. House is a beautiful example of how old and new can come together seamlessly. The four-storey Victorian terrace has transformed into a warm and welcoming home for a young family, without losing its historic charm.
Inside, the layout has been reimagined so that the original rooms have been kept as is, while new spaces open up toward the back, allowing light and air to flow through the house. A central staircase acts as a spine, bringing everything together and helping the home stay comfortable year-round through smart passive design.

Our Impact
Comfort Built into the Existing Envelope
Thermal mass from the masonry, paired with double glazing, insulation and natural ventilation, means the house stays comfortable year-round with less reliance on heating and cooling. It’s better for living, and better for running costs.
All-Electric Operation
The home operates entirely on electricity, no gas, no compromise. We upgraded the electrical system and made provisions for solar, creating a resilient, low-emission house that’s ready for the future. Simplifying services and aligning the build with long-term sustainability.
Material Reuse and Conservation
We retained as much of the original structure as possible from bricks and timber to the front rooms themselves reducing waste, conserving resources, and limiting disruption to neighbouring properties. Every element kept was one less truckload in or out.
Quiet Build in Tight Conditions
With no off-street parking and only 12sqm of storage, every material came through the front door. Careful sequencing, early trade involvement and off-site prep helped reduce noise, congestion and disruption for both the build team and the neighbours.
Our Process
Pre-Construction
With no off-street parking and just 12sqm of outdoor space, every material had to come in and out through the front door. This made early planning essential. Careful sequencing, design coordination, and value engineering were key to making the project feasible, not just buildable, but beautifully resolved.

Early Works
Surgical demolition was required to carefully retain the front rooms while preparing the structure for major alterations. Works included underpinning along the 4-storey boundary, salvaging original brick and timber for reuse, and creating pathways for new services .

Understanding structure interior linings were stripped first to check the condition of the existing building.
New roof structure was installed early to brace the existing walls of the terrace.
Structure
We staged As demolition progressed in stages, new structure was introduced section by section. A tight-tolerance steel frame threaded through the retained terrace, while salvaged bricks were cleaned and re-laid, embedding the project’s past into its future.
Temporary bracing supported the structure as we worked in stages of demolition and introducing new structure.
Recycled bricks dismantled bricks were cleaned, stored and then used in the new layout.
Enclosure
Thermal performance and comfort were upgraded throughout the envelope. Heritage elements like slate roofing were carefully replaced, while new elements including a patterned block facade and screen and double-glazed timber doors brought texture, insulation, and a considered response to orientation and privacy

Heritage slate removed and replaced around the rear arched dormer.
Interiors
A terracotta clad stairs winds around a column of light connecting all 4 levels of the terrace. Its precision set the benchmark for the interiors, demanding tight tolerances, critical alignments, and the co-ordination of high quality crafted metalwork, joinery and plaster.
Terracotta spine central to the design and masterclass in co-ordination and the exacting skill of the tradesman involved.
Arched dormer with zero tolerance plaster that wraps the timber casement and frames the glass internal skylight.
Aftercare
Additonal repaints, tops ups of landscape materials, tile sealing, additional services and on demand maintenance calls keep the house clean and functional.
