Located on top of the hill between Bondi and Tamarama. The first floor addition to the original brick bungalow was built to creat a parents retreat consisting of a large East facing bedroom with a generous walk-in robe and ensuite. Facing west a large lounge complete with a bar and small bathroom.

This new house emerges on a empty block punctuated by three large gum trees. The most commanding, standing tall at the centre of the site, remains as the focal point of the home. The house is defined by a gently curving roof, which mimics that of the gradually sloping site. Beyond its visual function of tying the house to the landscape, the curve provides privacy from the neighbours on the high side and bends down to open up the living areas to the light. In essence, the structure seems straight-forward, slab on ground, timber framing walls and roof, but when you add the curved rafters on top of 6m walls, built on top of finished burnished structural slab, things start to get a bit more interesting. Sprinkle the material and labour shortages on top and stir in some Covid restrictions and site shutdowns, the build no longer looks so simple.

Our Impact

Architecure that Lasts

We focus on what matters long after handover: durability, quality, and detail. Buildings should be made to last, and that principle guides how we work.

Our Committment to Sustainability

We approach sustainability as a practice, not a label. That means choosing materials carefully, reducing waste thoutfully, and building for longevity.

Investing in Craft

We invest where we see value and for us, that means preserving craft. Through apprenticeships, respect for technique, shared knowledge, and staying close to the work, we keep skill and care at the centre of what we do.

Reuse of existing Hardwood

Recycled hardwood is at the heart of our commitment to sustainability. By salvaging and repurposing timber, we give new life to materials that would otherwise go to waste. This approach reduces landfill, lowers demand for new logging, and delivers durable, high-quality finishes that Arc. is known for.

Our Process

Pre-Construction

1

A project where we were engaged from the outset, we worked closely with the clients and architects to shape the design, define construction strategy, and guide early decisions. The aim: deliver an upper-level addition with minimal disruption to the retained ground floor below. This required foresight, detailed sequencing, and protection measures across every stage.

After testing various approaches, SIPs panels were chosen for their speed, precision, and low-impact install. Structural engineering minimised load transfer to the existing home, allowing much of the ground level to remain untouched.

Early Works

Early works focused on protecting the retained ground floor while preparing for the efficient delivery of the upper level. Structural propping was installed internally to support selective demolition and allow for clean structural openings between new and old. At the same time, excavation works were undertaken to install the new OSD tank and drainage.

Structure

SIPs were selected for their precision, thermal performance, and rapid install, allowing the roof to be removed and the new upper floor enclosed with minimal exposure to weather. A new staircase was inserted into the centre of the house, linking old and new through a compact and efficient layout. Structural remediation was also undertaken to address deficiencies in the existing brickwork and integrate new structure.

Enclosure

The first-floor addition is wrapped in Barestone cladding, chosen for its clean lines and durability. Delicate aluminium window hoods surround each opening, providing shading and a refined architectural edge. Corner windows stack providing clear open corners, maximising ventilation and light . The vertical lourves fit within the hood and allow for contirl of privacy and light. A large skylight, craned into position, spans the stair void to bring daylight deep into the home.

Interior

The interiors focused on minimal, well-executed detailing. A timber batten screen conceals the stair and incorporates an integrated door, blending functionality with design. Custom joinery was installed floor-to-ceiling throughout the upper level, while the retained ground floor received a light refresh with new finishes and fittings.

Aftercare

Following completion, our Arc Care team has remained closely involved with the home’s ongoing upkeep. From coordinating subtrades to installing artworks and managing timber maintenance, our aim has been to ensure the home continues to perform and present at its best.
