Milan, 2004

Michele Dragoni, Enrico Lumini and Antonio Romano came from automotive, industrial design and interior design. They were asked to design a 66 foot boat together, and the commission turned into a partnership. The studio has been in Milan since, and moved into a new office in the centre of the city in 2024 for its twentieth anniversary.

Milan matters to the work. The city is the centre of Italian furniture and product design, which means the studio sits inside the supply chain it specifies from. When Hot Lab draws a piece of loose furniture or a fabric for a yacht, the maker is often an hour away. That shortens lead times on the part of a build that is most likely to run late.

Architecture for Voyagers

The studio works under the phrase architecture for voyagers and treats the interior and the exterior as one problem where it gets both. The result is contemporary without being severe, with a heavy emphasis on materials and on the transition between inside and outside deck. Staircases, ceilings and the joints between surfaces are where the studio spends its effort.

That focus is deliberate. On a 45 metre yacht an owner spends most of his time in four or five spaces and passes through the others. Hot Lab designs to that reality, which is why a boat of theirs often feels larger than its gross tonnage suggests. A Robb Report Best of the Best prize in 2025 for a staircase is a fair summary of where the studio's attention goes.

The tonnage on a Hot Lab boat reads 499, 462, 443, which is a design decision and not an accident.

The Columbus fleet

The closest yard relationship is with Columbus Yachts, part of Palumbo Superyachts. Acqua Chiara at 47 metres and 499 GT carries both the exterior and interior by Hot Lab. So does Night Fury II at 43.6 metres and 462 GT. Big Naan, 42 metres and 443 GT, has a Hot Lab interior under an exterior by Hydro Tec.

Columbus also revealed a 65.5 metre flagship concept, the Atlantique 65, with a Hot Lab exterior and interior at around 1,300 GT. The studio described the line as drawn from sailing yacht proportions and 1950s sports cars. For an owner, the depth of that relationship means the studio already knows the yard's engineering, its finishes and its subcontractors before a project starts.

Interiors under other people's exteriors

A good deal of the studio's work is the interior alone. The 54 metre Baglietto delivered in 2021 as C has an exterior by Horacio Bozzo Design and a Hot Lab interior across 905 GT, laid out for a large family. Bijin, 49.9 metres from Heesen and 499 GT, pairs a Hot Lab interior with an Omega Architects exterior.

That split is normal in this part of the market and it suits an owner buying into an existing platform. The hull and the profile are fixed by the yard and the exterior designer. Everything the owner touches is still open. An interior studio brought in at this stage has less freedom and more responsibility for how the boat actually feels.

Living below 500 GT

Look at the numbers on the Hot Lab fleet and a pattern appears. Acqua Chiara sits at 499 GT, Bijin at 499, Night Fury II at 462, Big Naan at 443. None of that is coincidence. Above 500 GT the regulatory regime, the required crew and the certification burden step up, and the annual cost of running the boat goes with them.

Designing a 47 metre that stops just under the line is a volume exercise as much as a styling one. Every ceiling height, every bulwark and every enclosed space is measured against the ceiling number. An owner who is told his 45 metre will be lighter to run than a friend's is being told something specific about how the interior was drawn. It is one of the least glamorous things a design studio does and one of the most valuable.

The Viken Group

Hot Lab was acquired by the Viken Group, which was set up in early 2022 by Tillberg Design of Sweden, a firm with deep experience in cruise ship and large vessel interiors. Viken had already bought the naval architecture firm Thalia Marine in April 2022. By April 2023 Hot Lab was described as part of the group with sixteen yachts in build.

For an owner this cuts both ways. The group can now offer naval architecture, interiors and large-vessel engineering through related companies, which widens what a single appointment can cover. It also means the studio is no longer three independent designers answering only to themselves. An owner should ask who is actually assigned to his boat and get the names in the contract.

How a commission runs

Most projects arrive either through a yard developing a model or through an owner who has already contracted a hull. Hot Lab produces the interior concept, the general arrangement work that follows from it and then the detailed drawings and material specifications the yard builds to. On a semi-custom Italian project the design programme runs for months and delivery typically follows two to three years after contract.

The studio was reported to have 22 superyacht projects under construction in 2024, which is a heavy load for a firm of this size. That is a reasonable thing for an owner to raise directly at the first meeting, along with how many projects the team assigned to his boat is carrying and what happens when two of them hit their fit-out peak in the same quarter.

What it costs, and where responsibility stops

Interior design at this level is charged against defined stages, with a concept fee, a development fee and then detailing and site support. On a 45 to 55 metre Italian build the interior design fee is a modest fraction of a price measured in tens of millions. The cost that hurts is the specification itself, since the studio can draw a stone floor or a bronze staircase that costs more than the design work several times over.

Hot Lab does not build the interior and does not carry the yard's schedule. Naval architecture belongs to the yard or to another firm. An owner should hold the studio to drawings and specifications delivered on time and hold the yard to what it agreed to build from them.

Recognition, and who it does not suit

The studio was named Designer of the Year at the 2025 International Yacht and Aviation Awards and took a Robb Report Best of the Best prize the same year. Its own count is more than sixty launched projects and eighteen awards. Recognition of that kind helps a boat at resale by a small margin and confirms the finish met a standard specialists would defend.

This studio does not suit an owner commissioning above 65 metres, where the portfolio thins. It does not suit anyone who wants a classical or period interior, since the work is firmly contemporary. An owner who wants his designer to control the hull and the performance figures needs a naval architect appointed alongside, or a different studio entirely.

Who it is for: Owners building 40 to 55 metres at an Italian yard who want a contemporary interior and a boat that stays cheap to crew.
