Bannenberg & Rowell

What Jon Bannenberg actually changed

Bannenberg set up in London in the early 1960s and is routinely called the father of modern yacht design, which is the kind of phrase that stops people asking what he did. What he did was treat a yacht as a designed object with an identity, at a point when most large motor yachts were naval architecture with furniture put into it. He argued for profile, for character and for interiors that were not simply grand.

Nabila, 85.9 metres from Benetti in 1980, is the boat that made the case. She was enormous for her day, she nearly broke the yard that built her, and she established that a private yacht could be a piece of design worth arguing about. She is still afloat, now called Kingdom 5KR. Andrew Winch, Terence Disdale and Tim Heywood all came through Bannenberg's office, which is why three of the biggest names in British yacht design share a grammar.

The handover

Jon Bannenberg died in 2002. The studio was renamed Bannenberg and Rowell in 2003, when Simon Rowell joined the management team as creative director alongside Dickie Bannenberg, who had by then worked in the practice for many years. That is the transition most single-name studios never manage, and a good number of the offices in this directory still have not addressed it.

The second-generation studio has delivered around forty yacht projects since the rebrand, with residential and transport work running in parallel. It has been careful not to trade purely on the name. An owner considering the studio should judge the last twenty years of work on its own terms, which is exactly the position the current directors take.

Three of the biggest names in British yacht design came through Jon Bannenberg's office, which is why their work still shares a grammar.

Fulham, and the archive

The office occupies an industrial building in Fulham in southwest London. It houses the design studio, a full soft furnishings and sampling library, and the archives of the original practice going back to the 1960s. Very few design offices in any field hold sixty years of their own drawings.

The sampling library matters more to an owner than it sounds. Interior schemes at this level live or die on material selection, and a studio with its own physical library can put fabric, leather, stone and veneer in front of a client in one afternoon instead of ordering samples for six weeks. It shortens the slowest part of an interior commission.

No house style, on purpose

The studio describes its work as creative, contemporary and approachable and resists settling into a fixed look. Colour, wit and unexpected material choices turn up regularly, and the boats do not obviously resemble each other. That is a deliberate inheritance from a founder whose whole career was spent breaking the conventions of his own period.

For an owner this cuts both ways. Someone who arrives with a clear idea will find a studio that engages with it instead of steering him towards a template. Someone who wants to buy a known look, in the way a buyer chooses a particular exterior designer precisely because every boat is recognisable, will find less to hold on to. It is worth asking to see three recent projects and noting how little they have in common.

Renaissance and Avantage

Renaissance, 112 metres, was delivered by Freire Shipyard in Spain in 2023 with both the exterior and the interior from the studio. She is the largest superyacht ever built in Spain, which makes her a first for the yard as well as the largest boat the studio has drawn. Avantage, 87 metres, came out of Lurssen in 2020, again exterior and interior.

Those two are the evidence that the practice can carry a whole boat at scale, not only decorate one. Working at a yard delivering its first vessel of that size is a particular risk for a designer, because there is no established engineering routine to fall back on and every interface has to be invented. Getting Lurssen and a first-time 112 metre builder in the same portfolio is a broad spread by any measure.

Valor, and interiors inside other people's boxes

Valor was launched by Feadship in May 2025 at 79.5 metres and 2,025 GT over six decks, with Studio De Voogt taking the naval architecture and the exterior and Bannenberg and Rowell the interior. She has a two metre ice belt above and below the waterline and a Bureau Veritas Young Ice 2 notation, which qualifies her to transit the Northwest Passage. Her propulsion is diesel-electric hybrid with four variable-speed generators, a water-cooled lithium-ion battery bank, a solar array on the mast and twin Schottel azimuthing thrusters, and Feadship quotes zero-carbon operation for up to two days.

An explorer interior is a distinct discipline. Furniture has to be secured for conditions a Mediterranean yacht never sees, surfaces have to survive wet gear and cold, and the crew spaces carry a heavier load because the boat is used harder. The studio has similar work behind it. Predator, 72.8 metres from Feadship in 2008 and the first Feadship delivered with a reverse bow, carries a Bannenberg and Rowell interior and took a Neptune at the World Superyacht Awards in 2009.

Refits, which many studios avoid

The office takes refits as readily as new builds, and that is unusual at this level. Predator returned to Feadship in 2016 for a refit that added two guest suites. Scott Free, the 60 metre Abeking and Rasmussen delivered in 2009 as Elandess with a Donald Starkey exterior, carries a Bannenberg and Rowell interior.

Refit work is a harder brief than a new build and it pays less. The structure, the systems and the deck heights are fixed, half the drawings are missing or wrong, and every discovery on site costs money that was not budgeted. A studio willing to do it is a useful appointment for an owner buying a good hull with a tired interior, which at current new-build prices and delivery slots is an increasingly sensible route into a large yacht.

How a commission runs, and what it costs

The studio works closely and informally with owners from concept through delivery, on new builds and refits alike, and its designers stay on a project through construction to protect the scheme. There is no naval architecture in house, so the yard or an outside office holds the hull, the structure and every performance guarantee in the build contract. On a Feadship the platform comes from Studio De Voogt. Commercially the design agreement is separate from the build agreement and is signed and paid first, in stages, which means an owner can stop after concept for the price of the concept and can take the drawings to more than one yard for quotation, subject to the confidentiality undertakings the studio will require.

No studio at this level publishes a fee scale. The market band is 1 to 5 per cent of build cost for the designer and 2 to 4 per cent for project management, both outside the yard's quoted price, per the SuperYachtReview guide updated March 2026, and a mandate covering exterior and interior sits in the upper half of it. A refit is a different animal. It is faster, far less predictable, and the design fee is a smaller number attached to a much larger unknown, because a refit specification is written against a boat nobody has fully opened up yet. A contingency of real size should be budgeted and expected to be used.

Recognition, and who it does not suit

The studio's work has been recognised repeatedly, including the Neptune for Predator in 2009, and the Bannenberg name still carries weight across the industry. Awards are worth a narrow amount to an owner, confirming a finish standard and helping a broker at resale. The more useful signal is the spread of yards, which runs from Feadship and Lurssen to a Spanish builder and a German one, on new builds and refits alike.

This studio does not suit an owner who wants to buy a recognisable signature, because the practice deliberately does not have one. It does not offer naval architecture. It is not the obvious choice above about 112 metres, and it is not a sailing yacht office. Anyone who wants formal, polished grandeur will find the work too playful for the brief.

Two principals, an archive, and what the contract should cover

The practice runs on two named people, a director and a creative director, in a studio Forbes described as twelve strong in February 2017, and no current headcount is published. That concentration is part of what an owner is buying and it is also a risk that the standard documents ignore. The ITIC standard trading conditions for naval architects, dated 8 July 2025, cover intellectual property and cap liability at ten times the consultant's charges or GBP 100,000, whichever is higher, and say nothing about the unavailability of a named principal. Commercial consultancy handles this routinely, treating death or long incapacity of a key person as a termination event and requiring a replacement of equal standing subject to the client's approval.

The drawing question is sharper here than at most studios because of the archive. Copyright normally stays with the designer, with the owner licensed to build one hull, and superyacht practice at its best converts that into an exclusive, irrevocable and assignable licence, which is the standard clause Federico Santini describes in Barche magazine in August 2018. On a refit the same logic applies to the original designer's drawings, which the studio will not own and may not be permitted to copy. An owner buying a good hull that needs a new interior should establish who holds the as-built drawings before he signs anything, because that answer sets the cost of the whole project.

No signature means nothing to date

The deliberate absence of a house style is the most resale-friendly position in the directory, and almost nobody buys it for that reason. A boat that does not announce a studio also does not announce a decade. There is no fashionable silhouette to fall out of fashion and no theme the next owner has to either adopt or rip out. Ocean Independence, on 11 May 2026, ranks builder pedigree, specification and condition above cosmetic detail in what holds value, which is a polite way of saying the market prices the boat and not the byline. Work that is unformulaic by intention slips through that filter without a penalty.

Against that, the Bannenberg name still carries with brokers and with the trade, and it earns a hearing that an unknown studio would not get. The one place the approach costs money is with a buyer who wants to be told what he is looking at. Something recognisable is easier to market in a listing photograph, which matters when the median yacht of 24 metres and over took 277 days to sell in 2025 against an average of 487. A characterful boat with no obvious label needs a broker willing to explain it, and is worth more to the buyer who works that out for himself.

Who it is for: Owners with a clear idea of their own who want a characterful, unformulaic result, on a new build or on a good hull that needs a new interior.
