Starting a factory is a complex, pain-in-the-arse type of thing – that’s why most brands don’t do it. So the people we really took advice from were the people running the old factory. They helped us set up, told us what to do, what not to do. We were novices and naïve; they were skilled and had done it for decades.

Even if the only thing you’re after is a place to drink after all the other bars have closed, this is fantastic value for money. In a unique upstairs conservatory, the dining room was a real charm in this property, with so much natural light and extensive views across the neighbourhood. The client wanted to maintain the charm but add the comforts of a modern entertaining space. We started by replacing the flooring with a Victorian patterned green tile and cleaning up the windows, which were rotting and damaged in many places. We created a modern bar at one end using new cabinetry and dark green tiles while the rest of the dining space received new custom furniture. An oversized (long but thin) dining table to fit at least 10 people was crucial for our client. Hiut is only ever going to make jeans because it has the knowledge, the skill and 40 years of learning behind it. We are confident on how to do one thing well and we have no ambition to do anything other than that. We’re a singular product company selling direct to the consumer and that product is super-high-premium-quality jeans. That's our complete and utter focus. Anything else is a distraction. You’ve also successfully set up two businesses now. What advice would you give to someone who has an idea but also has life responsibilities?Being able to ‘accidentally’ flash your Annabel’s membership card every time you open your wallet. There really is nothing else quite like it. The original Harry’s Bar in Venice made its name inventing the bellini. Its London counterpart remains one of the most sophisticated and elegant clubs in London, if not the world. Unlike many of the entries on this list, it does not have a nightclub, a heated swimming pool, a vault load of wine, nor an MRI machine. What it does have is unquestionable class and staff that understand members like they are family – from knowing their favourite tables to their favourite food and which drinks to have chilled in anticipation of their arrival. The dress code is strictly suits and strictly adhered to, which is why the clientele love it. Far from being an old-school or stuffy establishment, it attracts many members are in their 30s and 40s who appreciate the elegance and formality. A members club that you can visit without being a member. This is a different kind of club and it won’t disappoint.

Other than the TV studio? There’s a 36-seat screening room and the club hosts four exhibitions of contemporary artists each year. I have blood tests every three months. I highly recommend Omnos – it offers a range of tests, some of which can be done at home, measuring everything from your testosterone levels to thyroid function and blood count. I get tested regularly to keep an eye on vitamin and nutrient deficiencies and then supplement accordingly. At the moment, I’m taking creatine to support muscle synthesis, collagen for my gut health and adding chaga powder to smoothies. Don’t be lured by CBD – it claims to be the cure-all for everything, but it only works on a short-term basis. If your diet and lifestyle aren’t great, your endo-cannabinoid receptors will likely be empty, meaning CBD will work like a charm, but once any deficiencies have been corrected (usually within four to six weeks), you won’t continue to see results. Alfred’s will afford each of its select members with an exceptional restaurant nurtured by Executive Chef Mark Hix The starting point here was rich saturated artwork and warm earth tones that felt cosy enough to relax in yet interesting enough to be entertaining. Once we established the layout for the space and realised it needed a long L-shaped sofa, we started layering fabrics and rug combinations until we found the perfect pairing. The oversized footstool was an important piece to have made as it allowed more foot rest while watching a movie as well as being used as a coffee-table surface. We also created bespoke, built-in cabinets on either side of the fireplace to help balance the space and anchor the room.

Membership gets you access to one of the best rooftops in the city. There is also the legendary Vault bar housed in the original Midland Bank strongroom which stays open until you decide to leave. The Hospital Club was co-founded by Paul Allen of Microsoft in 2004. After a rebrand, it is now simply the H Club. It is open for breakfast, lunch, dinner, and has 15 bedrooms available. It is also the only club in London with a full-on TV studio, where Top Gear: Extra Gear has been filmed. I fell in love with denim and the history of the fabric when we were doing Howies. Just like coffee is really, really geeky, so is denim. There are some really great selvedge fabric mills in Japan, which are the elite. We begged them to work with us when we were starting out and my obsession began from there. Everything about the process – from plantation denim to the original selvedge narrow looms and visiting denim factories – is just a brilliant experience for me. Leaving a good salary is hard, so I would advise starting a business as a side project. That allows you to see two things: if you like it and if your customer wants it. Being an entrepreneur isn’t for everyone – there are stresses and strains. Sometimes people only see the upside and the glamour, not the decades of hard work. That said, while leaving a cushy job is difficult, quitting on a dream is even harder, so I would encourage you to follow your heart. I always need a good cup of coffee en route to Da Terra. My favourite coffee spots have to include Ozone – the team make a delicious cup and are really conscious of their sourcing of the beans. I also love The Beehive. They are such a friendly bunch, the coffee is delicious and – crucially – it's really close to my restaurant, so I go there a lot. FOR LUNCH

Two swimming pools, one on the rooftop and one in the basement sets this club aside from many other London member’s clubs. I was always fascinated by brands and dreamt that one day I would have my own. Pre-Hiut, my wife and I started the clothing brand Howies, but we were pretty inexperienced at running a business. We thought fast growth was this really amazing thing, but actually it was killing us. We ended up selling Howies in 2006 after it grabbed the attention of some seriously professional brand builders. Steve Case, who started AOL, wanted to invest but take it to California. PPR – which owned Gucci, Saint Laurent and Puma – made a list of two brands in the world it wanted to buy: one was Quiksilver; the other was Howies. Japan’s richest guy was interested too but in the end, we sold to Timberland as it believed Wales was important to the brand’s integrity and we shared that point of view. It’s still a shame though, because if we’d slowed the growth of the business down, we would’ve kept control and I’m pretty sure we’d still be doing Howies today. One of London’s best kept secrets, what happens in 5 Hertford Street stays in 5 Hertford Street. Often seen as Annabel’s younger, cooler cousin, the club was opened 7 years ago by Robin Birley, son of Lady Annabel Goldsmith and the late Mark Birley the renowned members club chieftain who had a hefty club portfolio including old Annabel’s. Robin has taken his classy, charismatic and dazzling upbringing and used his connections to create a sanctuary for cool club-goers. The décor feels luxurious but lived in, with endless mementos, photos of family members and fireplaces in most rooms. The club is a rabbit warren of rooms in four adjoining townhouses within which are highly themed restaurants, private dining rooms where dogs are welcomed, a cigar room, three bars, a library, a drawing room, alcoves for bookworms and the famous late night watering hole LouLous, which is great for some Friday night fun. Be under no illusions, the crowd here is just as Sloaney as any members club you might find in Mayfair but remains a club where your grandparents will feel as comfortable spending their Sunday as you did spending the early hours of Saturday morning. When the original Soho House opened on Greek Street in the mid-90s, it set a standard of luxury and unlike other private members clubs was exclusively for those that worked in media industries. Apply for membership if you had a job in the city and the answer was a resounding no. Today the concept has been rolled out across the globe from Soho Farmhouse in the Cotswolds to Miami and to its newest London venue, White City House. But it is Little House that is the unassuming hero of the Soho House collection. It occupies one floor of a small building on a quiet corner in Mayfair and has a feeling of old fashioned glamour thanks to the mixture of new and vintage furniture, dim lighting, deep dining booths and fireside sofas. Guests can eat from the ‘little menu’ which features simple, seasonal dishes whilst listening to live music every evening from 7pm. It’s the place to be for royals, billionaires, A-list celebrities and socialites so expect service to be second to none with a price tag that is more reasonable than you would expect. The night club LouLous is the cherry on the cake.A Mayfair institution, and it’s easy to see why. Harry’s Bar membership also gains you access to its brother clubs George and Mark’s Club A standing desk is a proven way to aid concentration and focus. When you stand, blood flows significantly better, which is great for engaging your brain. By balancing on your feet, you also engage the core and muscles in the lower body. I use a standing desk at home and stand for most of the day. Founded in 1985, The Groucho was the original media members' club – a group of eccentrics, hearty drinkers and influencers whose A-list all-nighters became the stuff of legend. Despite being an old guard in any members list, a recent refurbishment has given the club a rich and comfortable, fresh yet informal new feel. The club has two fantastic restaurants, 20 furnished bedrooms as well as a selection of private event spaces available for both members and guests. Laced with Cool Brittania lore , think works by Tracey Emin, Mark Quinn and Damien Hirst who is rumoured to have put his entire Turner Prize winnings behind the bar, this club is a monument to the British art scene, individualism and a good old fashioned knee’s up. Once home to the Duke of Westminster, Bourdon House is now a one-stop shop for the modern gentleman. As the only detached house in Mayfair, this grade two listed Georgian building has, like Alfred Dunhill, long since represented grandeur and distinction in British heritage. The retail aspect of Bourdon House is set over three floors, catering to every modern gentleman’s need. The ground floor showcases Dunhill’s signature lines of ready-to-wear whilst the second floor hosts a unique spa waiting room called The “Discovery Room,” a spa replete with two treatment rooms, a traditional gentleman’s barber and an elegant museum curating pieces from the brand’s archives. In the basement is a private cinema, equipped with a state of the art British-made sound system, a cigar room, a games room, ‘dishonesty’ bar, courtyard for al fresco entertaining; private dining room, four bedrooms including a sumptuous suite recreating the original sleeping quarters of the Duke himself. The staff, but also the beautiful heated terrace – ideal for people watching in Mayfair over limoncello.

Gallery-worthy works of art are on display around the club which are often specially curated and frequently changing. Its basement club Leo’s hosts the best live performances in London. Membership is worth it for access to Leo’s alone. A great central location to hang out, the club offers everything from accommodation to co-working spaces and has partnerships in most major cities of the world. Annabel’s is opulent, loud, over the top and has recently under gone a multi-million pound overhaul –the beautiful queen of the members club scene. No membership collection is complete without an Annabel’s mention. If you have a disposable income and are willing to spend big at every visit then this is the club for you. Boasting no fewer than five restaurants – one in a garden terrace with London’s largest retractable roof – it also has a nightclub with daily shows from the likes of James Blunt, the Gipsy Kings and Jess Glynne. Even on your 100th visit to Annabel’s, you’ll find yourself staring at something you haven’t seen before. The Court has partnerships with brands such as The Foundry, Penhaligon’s and Bird + Wolf, meaning discounts for members. Join now and you’ll be one of the first inside what looks set to be a very popular club.If we sell out, people have to wait. Sometimes they’ve had to wait six months. I don’t want people to wait six months for a pair of jeans – that’s excessive – but sometimes you can’t keep up with demand and that’s just the way it is. You can't suddenly go and hire 20 more people because you have a sales spike. Authenticity, originality, and quite possibly the experience that comes with age – what this club has in spades cannot be replicated. This is the sort of place you’d want to take your future father-in-law to ask for his daughter’s hand in marriage, or the sort of place you’d like to take your daughter’s fiancé to question his plans for their future. In an old bank, 67 Pall Mall has over 520 wines available by the glass at very reasonable prices. That’s because the whole place was born from its founder’s frustration at excessive markups on wine. Yeah, we spent six months doing business plans butso you know I hate business plans. I hated every minute of that six months because we had to go down to the post office and find out minute details like how much it was going to cost us to send out a pair of jeans. But, as painful as it was, knowing your numbers is really important. When you don’t know your numbers, you’re going to have to raise more and more money. It can be the difference between failure and success.
