Terence Disdale Design

Fifty years at 6 The Green

Disdale set up in 1973, which makes this the oldest practice in this directory still trading under its founder. The office is at 6 The Green in Richmond upon Thames, a short walk from the river and about forty minutes from central London. He came up in the same London design world that produced Jon Bannenberg's studio and the generation of exterior designers that followed it.

Over fifty years the studio has completed close to a hundred yachts, around half of them above 50 metres. The output has not been evenly spread. The very large work has come in concentrated bursts, and the last fifteen years alone have produced three of the longest yachts ever handed over. There is no other office of this size anywhere in the field with that record.

Fifteen people

The team is around fifteen. That is a deliberate choice and it has been held for decades against every commercial argument for growing. It keeps the founder's hand on every project and it lets the studio decline work, which is a luxury most practices cannot afford.

An owner should weigh what that costs him as well as what it buys. Capacity is limited and a project waits its turn. There is also the succession question, which is fair to ask of any single-name practice before signing a contract that will run four years and outlive several yard directors. Against that, the person who takes the brief is the person who defends it in the yard's meeting room in year three, and at this end of the market that is worth a great deal.

Fifteen people in Richmond have been handed three of the longest yachts ever built.

Beach house, not penthouse

Disdale's stated position is that most yacht interiors are too formal, and his answer has been relaxed rooms built from natural textures, soft light and materials that look better used than new. The exteriors carry the same lack of ceremony, with balanced masses and no gimmicks. It is easy to underrate as an idea. It is very hard to execute, because informal only reads as luxury when every element is genuinely good.

The studio is equally explicit about two unglamorous things, which are the client's budget and the maintenance burden. Finishes are chosen with an eye to what a crew will actually have to keep looking right in salt air for twenty years. That is the difference between a yacht that photographs well at handover and one that still looks correct in its third season. Owners rarely ask about it at concept stage and always notice it later.

Eclipse

Eclipse was delivered by Blohm and Voss in 2010 at 162.5 metres, with both the exterior and the interior from the studio. She was the largest yacht in the world when she was handed over and she held that position for several years. She is also the project that fixed Disdale in the public mind, since almost nobody outside the industry could name the designer of anything else that size.

The interesting part is that she does not look like a statement of scale. The proportions are held down, the superstructure is stepped so no single mass dominates, and the interior is the same relaxed vocabulary the studio uses on a 50 metre. Scaling an informal aesthetic up past 160 metres is far harder than scaling a formal one, because formality has grand rooms to hide behind and informality does not.

Blue and Opera

Blue came out of Lurssen in 2022 at 160.6 metres and 14,785 GT, with exterior and interior by the studio and naval architecture by the yard. She runs four MTU diesel-electric engines to a top speed of 20 knots and cruises at 18, on a 22.5 metre beam. She is among the largest yachts in the world with hybrid diesel-electric propulsion. Opera followed from the same yard in 2023 at 146.35 metres, again exterior and interior.

Blue's numbers hold the useful lesson. She is arranged for 48 guests in 40 staterooms with 80 crew, and a guest count of that size takes a vessel out of the ordinary private yacht rules and into a passenger regime, with everything that implies for escape routes, fire zoning and structure. An owner contemplating anything above twelve sleeping guests should understand that decision changes the entire build, and it has to be taken at general arrangement stage.

The interiors under other people's exteriors

The studio's own listing singles out the interior of Pelorus, the 115 metre Lurssen delivered in 2003 to a Tim Heywood exterior. A+, delivered by Lurssen in 2012 at 147 metres under the name Topaz, is another Heywood exterior over a Disdale interior. Ecstasea, 85.95 metres from Feadship in 2004, carries a Disdale interior over a De Voogt exterior, arranged for 14 guests in seven cabins.

That pattern says something about how the industry uses this office. Two of the strongest exterior studios in the field will happily hand it the inside of their largest boats, which is not a courtesy anybody extends twice if the first result was difficult. For an owner splitting a commission between two studios, a designer with a long record of working under other people's profiles is a lower-risk appointment than one who has always controlled the whole hull.

The small end, and why it still matters

Sussurro was delivered by Feadship in 1998 at 49.5 metres with exterior and interior by Disdale and naval architecture by De Voogt. She is aluminium throughout with a GRP element in the superstructure. She was built light and built to go fast, at a point when Feadship was known for neither. She is still regarded as one of the more interesting boats the yard has produced.

A 50 metre is the harder design problem. There is nowhere to put anything, every square metre is contested, and the compromises are visible. A studio that can make a 50 metre feel generous is applying the same skill when it makes a 160 metre feel intimate. Owners looking at a first boat in the 40 to 60 metre bracket should not assume a name associated with giants is uninterested in them.

How a commission runs, and what it costs

Disdale works directly with owners and with a small number of yards, above all the German builders capable of the largest hulls. The studio takes the brief personally, and its stated method starts from the owner's actual use of the boat and his budget before it starts from a look. The engagement is staged and the design contract precedes the build contract, which means an owner is paying this office for a year before a yard is committed to anything. Site attendance through construction is billed as a separate service rather than folded into the design fee, and it is the item to protect, because an unpoliced design degrades quietly as the yard proposes cheaper details.

Nobody at this level publishes a scale. The market band is 1 to 5 per cent of build cost for the designer and a further 2 to 4 per cent for project management, both outside the yard's number, per the SuperYachtReview guide updated March 2026. On a 160 metre hull the arithmetic is uncomfortable to write down and still a small line against the build. What an owner is buying at the top of that band is exterior and interior from fifteen people rather than from two houses that have to be refereed. What he is not buying is naval architecture, which stays with the yard along with every performance guarantee in the build contract.

Recognition, and who it does not suit

The studio has taken design awards across five decades and its influence is visible in work signed by other people, since the relaxed interior has been widely copied since the 1990s. Awards are worth a narrow amount to an owner. They confirm a standard of finish and they help at resale. The more useful signal here is that the same fifteen people have been given the largest yachts in the world three times.

This studio does not suit an owner who wants hard, polished, formal glamour, because the whole practice is built against it. It does not offer naval architecture. Capacity is limited and an owner in a hurry will not be accommodated. Anyone who wants a large team of account managers responding to design changes at speed through a build should appoint a bigger house.

Fifteen people, one name, and what the contract should say about that

A studio of fifteen carrying its founder's name concentrates risk that a larger office spreads. The professional standard forms are no help. The ITIC standard trading conditions for naval architects, in the version 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 at all about what happens if the named principal is unavailable in year three of a five-year build. That silence is the market norm, not an oversight by this studio.

The remedy is contractual and ordinary. Commercial consultancy treats death or prolonged incapacity of a key person as a termination event and obliges the consultant to propose a replacement of equal standing for the client's approval. A design agreement can carry the same clause, together with a right to the complete drawing and specification set in native format if the practice ceases trading. Copyright normally remains with the studio and the owner buys a licence to build one hull, so without that step-in right an owner holds permission to build a boat and no files to build it from. Fifty years of continuous trading is a good sign. It is not a substitute for the clause.

Relaxed ages well, very large does not sell fast

A Disdale interior is easier for a second owner to live with than most, because the palette is informal rather than personal and the approach has been copied so widely since the 1990s that it now reads as a familiar idiom instead of one man's signature. Teak, rattan and low-key materials also wear in a way that looks intended, which is the opposite of a high-gloss interior where every mark is a defect. That is a genuine, if unglamorous, resale advantage and it is worth more than the awards.

The constraint is size, and it overwhelms everything else. Above 140 metres the number of credible buyers worldwide is small enough to count, running costs are the real barrier to entry, and a boat can sit for years without that saying anything about its design. Against the 470 sales of 24 metres and over recorded by Denison Yachting for 2025, at an average 487 days on market, the largest yachts are a different market with different arithmetic. An owner commissioning at this scale should assume the boat is illiquid by construction and should value the design for the twenty years of use rather than for the exit.

Who it is for: Owners who want relaxed, informal luxury on a very large yacht and value discretion and a designer who answers his own phone.
