Now live: Bottega Veneta, Sydney.

A three-level flagship defined by precision, materiality, and craftsmanship, this project brings an international design vision into a highly resolved local context. From the sculptural timber stair to the hand-laid terrazzo flooring, every element has been carefully considered and executed.

Behind every refined space is a highly coordinated process. Working closely alongside the client, consultants, and project teams, Asentis played a key role in bringing the project to life through detailed coordination, technical expertise, and a collaborative delivery approach focused on quality at every stage.

In the heart of Kesko’s K-Kampus headquarters in Helsinki, a sculptural staircase anchors a vast glazed atrium bringing together nearly 1,800 people and creating a natural point of connection within the workplace.

The building reflects the core values of Scandinavian design; functionality, clarity, and a deep sense of consciousness in how space is made and experienced. Rooted in Modernist principles, the architecture prioritises durability and authenticity, where every detail is considered and nothing is excessive.

A considered palette of timber, exposed concrete, and soft natural tones carries through the interiors, reinforcing a calm, cohesive environment.

We’re inspired by this approach, where clarity of vision and careful material choices come together to create spaces that feel purposeful, enduring, and human-centred.

At the heart of Sydney’s CBD, Brookfield’s Australian headquarters at Brookfield Place reflects the company’s commitment to quality and innovation.

Designed by and delivered by , the workplace features a refined material palette of marble, polished stainless steel, and deep ochres, creating a gallery-like environment inspired by modernist geometry and form.

At its centre is a striking full-turn spiral staircase connecting three levels. Rising over 7 metres with a diameter of more than 5 metres, the steel-plate structure — finished with polished plaster — acts as both a functional connector and sculptural focal point.

Working closely with Bates Smart from early design development, Asentis helped bring this ambitious vision to life through detailed collaboration and technical expertise.

Stringers do more than support; they define the stair. Their form is guided by both engineering performance and architectural intent. At Asentis, each stringer is developed through close collaboration between design and engineering, ensuring structural integrity while shaping the stair’s spatial character.

Three stringer types we love:

1️⃣ Plate Stringers — sleek, minimalist support. HPX Group, Sydney demonstrates how a slim steel plate complements a delicate mesh balustrade.

2️⃣ Box Stringers — clean, structural elegance. RACV, Melbourne showcases a streamlined design paired with a steel balustrade, creating a seamless architectural statement.

3️⃣ Sawtooth Stringers — rhythmic and sculptural. LGT Crestone Wealth, Melbourne features a timber stringer as a bold architectural statement against a refined white palette.

Each type offers unique possibilities for both structure and design. The right choice can transform a stair from functional to unforgettable.

A workplace inspired by connection, craft and nature.

For New World Development’s HQ2 in Hong Kong, the design reinterprets the traditional siheyuan courtyard as a contemporary workplace, encouraging collaboration, creativity and wellbeing.

A central feature stair links four levels of the headquarters, supporting movement and informal interaction between teams. Warm timber, lattice screens and natural textures soften the space, strengthening the connection to nature while creating a calm, crafted environment for employees.

Sustainability is embedded throughout, with more than 60% of finishes incorporating sustainable materials including FSC-certified timber, recycled terrazzo and low-VOC finishes.

Spaces like this remind us how powerful thoughtful workplace design can be. At Asentis, we’re continually inspired by environments that bring people together through design.

The Opera Park in Copenhagen is a rare green escape in the heart of the city. 🌿

Within the garden café, the stair’s gentle curves mimic organic shapes, flowing naturally through the glazed stairwell. Crafted in a warm palette of timber and steel, it complements the lush gardens, creating a seamless connection between indoor and outdoor spaces.

This is the kind of design we love at Asentis; stairs that enhance place and transform movement into experience.
