Gentle Confidence: SIR Bondi Flagship by Tamsin Johnson.

Founded in 2014 by Nikki Campbell and Sophie Coote from their Bondi apartment, cult Australian fashion brand SIR celebrates seven years by opening the doors of its Sydney flagship right near the origins of the brand.

Designed by Tamsin Johnson, the flagship boutique pays homage to the SIR evolution and an overall sentiment that is gentle and sculptural, yet unapologetically confident.

The shopfront offers a beautifully poised outlook with large pieces of curved glass, framed in steel hand-painted in a luxurious shade of espresso brown. This sophisticated entry honours a contemporary woman of taste that’s the SIR muse.

The interior features a polished concrete floor with Corian inlays that ‘click’ underfoot. Coupled with planes of translucent glass block, the perimeter walls are spray-rendered to mimic Bondi beach houses, with subdued colours that appear anything but stark or insensitive.

The palette of soft greys and off-whites mixes with tones of beige velvets and sheer cream linens, cleverly contrasted with smooth, reflective forms of stainless steel joinery and crisp planes of acrylic supported on sculptural bases.

The lighting is reductive and architectural in form, allowing for the vintage furniture pieces to take centre stage. Custom racking in heftier square-set profiles contrasts with gently curved and rendered fitting rooms. The details of hand-painted frames and hand-made metal hardware become focal points.

The furniture pieces are predominantly from the 1950s to 1980s, adding an artful and sculptural complexity to the space. French 1950s brutalist stools can be seen in the fitting rooms, while Swiss brand De Sede’s iconic DS-600 modular sofa upholstered in rich chocolate brown leather is the undeniable hero of them all. Under the sofa, a custom silk carpet in caramel tones reflects the Corian inlays found throughout.

Natural stone can also be seen, from rich earthy marbles played against sympathetic natural travertines, adding an element of texture to the interior that otherwise feels highly polished and slick. The result is a perfectly executed harmony of vintage, custom and contemporary elements.
