A village connected to the pulse of a modern metropolis.

3 bedroom residences individually designed and specified for Owner Occupiers.

Introducing a boutique development of just nine 3 bedroom apartments specifically designed for owner occupiers in the heart of Mosman. While Sonnet maybe boutique in scale it is grand in execution, offering security, sophistication, convenience and traditional homestyle values.

Rather than towering skywards like some of the incongruous nearby apartment buildings, Sonnet has been designed to embrace its snug residential location at the quiet northern end of one of the few cul-de-sacs in Mosman. Geometric symmetry, artisan details and understated elegance are the architectural hallmarks of the pet-friendly Sonnet.

The low-rise, linear building features a gently curving façade that over time will be visually softened by nature’s green tapestries. The architectural concept taps into the rhythmical spirit of its poetic name – a melodic 14-line verse meaning ‘little song’ in Italian – as it nestles lightly into the existing landscape. By embracing environmental initiatives such as solar panels, energy-saving sensor lighting, adjustable sun-shading louvres and thermal insulation the design focusses on minimising recurrent costs and strata levies.

Textured timbers, tactile stonework and sumptuous finishes showcase the much-lauded HELM style, transporting you back to the days of traditional craftsmanship and meticulous attention to detail.

The sophisticated interiors are imbued with natural light from the floor-to-ceiling glazed windows. Thanks to moveable screens you can adapt living conditions to the changing seasons, welcoming the outside in or closing up against the elements.

The expansive outdoor terrace is the result of HELM knowing the needs of its discerning clientele. It’s not the cramped balcony found in all too many apartment blocks; the terrace is extremely generous, with gas, water and electricity connections, making it ideal for enjoying alfresco meals.

While suiting a relaxed lifestyle, all apartments at Sonnet have the refinement and inclusions to host the most elegant cocktail or dinner party.

Hidden away is Chowder Bay designed to be browsed at your leisure. History’s on display amid the salty se a spray making naval-gazing a nautical pleasure.
