As Sirena Yachts’ 42-metre superyacht continues construction at the shipyard’s facility in Altınova Yalova, Turkey, BOAT speaks to the yacht's interior designer Enrico Lumini, co-founder and design director of Hot Lab, about the yacht’s design philosophy.
With the hull sections now welded together and over 30 skilled professionals working diligently to ensure swift progress, Sirena’s much-anticipated 42-metre is scheduled to launch in 2026 and is set to become the Turkish shipyard’s flagship.
The superyacht will feature accommodation across four lower-deck guest cabins, including two VIP suites with transverse beds. The owner’s suite is a standout area on board, positioned at the bow to grant direct access to a private forward terrace. A hallmark of the design is its focus on customisation, offering a flexible layout that allows for various configurations. For example, there is the option to expand the aft saloon into a versatile living area, ideal for a games room or studio, while the forward space can be dedicated entirely to dining. The design possibilities are boundless.
Less is more
Designer Enrico Lumini delves into the concept of “not seeing” on board. Imagine entering a beautifully lit room without being aware of the light sources, charging a phone without visible cables or enjoying perfect temperature and air-conditioning without any draughts. This approach aims to create a minimalist design while maintaining an element of curiosity through various “hidden” luxury features.
Lumini reflects on the design process, noting that the biggest challenge was “not overdoing it.” “When presented with such a stimulating brief, it’s easy to get carried away and risk overdesigning,” he explains. “At Hot Lab, our design philosophy has evolved over the years, and after two decades of experience, we have achieved a level of maturity that helps us distinguish between thoughtful design and mere spectacle. We don’t create theatrics; we design refined luxury interiors, resisting the urge to overdo it. Striking the perfect balance between creative expression and aesthetic sobriety was our greatest challenge.”
A 4D experience
Lumini envisioned a superyacht where the beauty extends beyond visual appeal, inviting owners and guests to experience it through touch and texture. The chosen materials include natural beech and oak, alongside soft cotton and chenille for the sofas. This selection results in a light and desaturated colour palette that Hot Lab believes enhances natural light. “We work with the colours that nature gives us and try to alter them as little as possible,” Lumini explains. “We rarely use stained woods or excessively flashy artificial stones, and the contrasting elements we consistently incorporate include metals, glass, and fabrics.”
He continues: “The craftsmanship of the stone walls, shaped with remarkable malleability, and the entire lighting system are probably my favourite features on board. Both aspects, being integral to the design and standout elements, required extensive attention to detail, research and verification, as well as thorough testing.”
Embracing nature
The yacht’s interior design combines Nordic and Mediterranean influences, emphasising circular and rounded shapes over sharp, cornered edges. This aesthetic is evident in the rounded artwork on the walls and the curved sofas in the main saloon, as well as the circular bedside tables and rounded chairs in the master suite. “The idea behind this concept is to merge two worlds: the organic, imperfect forms of nature, which lack flat surfaces and right angles; and the precision of human craftsmanship,” Lumini notes. “The smooth, curved surfaces represent both technical expertise and a naturally inspired aesthetic.” The design also incorporates plenty of plants to enhance the relaxed, organic atmosphere.
Lumini collaborated closely with exterior designer Luca Vallebona to ensure a close connection between the yacht’s indoor and outdoor spaces. “Luca is a dear friend, and together we collaborated on the key ideas for the project, especially in their connection with the outdoor spaces. The owner's cabin was the first area we designed, inspired by Luca's initial concept,” Lumini adds. “I very much enjoyed working in such a collaborative way.”
The 42-metre Sirena superyacht project is currently on the market with Ocean Independence and Northrop & Johnson asking €23,950,000. To find out more information, contact the shipyard today.
