With just nine apartments Sonnet is HELM’s smallest project, but it’s just the right size for downsizers and empty nesters and for preserving the Mosman way of life.

While Sonnet may be boutique in scale it is grand in execution, offering security, sophistication, convenience and traditional homestyle values. 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.

Rather than towering skywards like some of the incongruous nearby apartment buildings, Sonnet has been designed to embrace its snug residential location. 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.


On ground level are three apartments, two of which enjoy landscaped garden areas, with up to 98sqm of outdoor space on title. This is a bonus for any project, but it is a particularly prized feature for one so close to Mosman Village.

On the upper two levels are six apartments, each with three well-proportioned bedrooms, with extensive terraces. Careful acoustic planning means there is only one common wall between apartments, assuring occupants of a serene environment.


The external architectural elegance of Sonnet is matched by the premium nature of life within, where a sense of calm will envelope you the moment you step inside.

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.
