This palatial home in Port Lincoln, Australia, comes with its very own 26-foot aquarium. Filled with 10,000 litres of sea water it's populated by local Spencer Gulf marine life including snapper, mulloway and King George whiting. However, it's not the only unusual feature in the decadent home, it also has a topical garden with a glass aviary. 

There’s nothing we love more than intelligently integrated furniture. This design by Okeanos Aquascaping means you’ll be able to keep all your books and fish in one tidy and convenient place with this clever shelving unit.

Seafood might be off the menu after installing Kolenik’s aquarium kitchen island into your scheme. This unique worktop adds another level of luxury to your cooking space. Unexpectedly functional, the aquarium is built in an L-shape, hiding generous amounts of storage and a large usable countertop as well as a sink and hob.

Aquarium Architecture’s home aquatic centre is impressively futuristic. The curved design of the tank adds to the minimalism of the landing but is sharply contrasted with the splashes of colour and life brought by the fish. The expensive collection of tropical fish were sourced from South America and includes a rare Arowana: this species can cost up to £5,000 ($6.5k).

It’s not up for debate: this tank by Arc Design Group is one of the most lavish wine storage areas we’ve ever seen. The centrepiece of the room is the tasting area and so all other features circle around it, but this doesn’t divide attention away from the fascinating aquarium fitted into the Mediterranean-inspired stonemasonry.

Tired of boring old metal fences surrounding your multi-million-pound property? Mehmet Ali Gökçeoğlu, a wealthy Turkish businessman, splashed some of his spare cash on a 50-metre aqua-fence to circle his mansion in the coastal town of Çeşme. It has since become something of a tourist attraction, with thousands visiting the billionaire backyard every day!

Combining two opposing natural elements, this is Seavisions’ Wilminton fireplace with its aquarium surround. Imagine fire-gazing while the elegant creatures gently bob around; it offers unrivalled serenity for when you're unwinding or entertaining at home.

Acqua Liana is a luxury home in Manalapan, Florida designed by developer Frank McKinney to be ‘the greenest mansion in America’. He enlisted Magnificent Aquariums to bring part of his vision to life and they truly lived up to their name. Putting a new meaning to the term ‘wet bar’, this dazzling archway and countertop combination will make your jaw drop.

Here's a brilliant way to connect two rooms but still maintain a certain level of privacy. Aquatic Design’s arrangement is ideal - you feel detached enough from the other room to keep your noses out of each other’s business, but, if you’re getting separation anxiety, you can always send a wave through the transparent glass. Or maybe, if you’re lucky, have your own Romeo + Juliet moment...

Alternatively, Living Color Aquariums provide a different take on the room divider, seizing the opportunity to break up a large room with a touch of elegance and class.

Holy carp! This aquarium is not meant for those of a delicate disposition: the truly carnivorous tank is home to 17 bloodthirsty red belly piranhas. Just don’t put your hand in – the consequences could be disastrous! 

If you’re looking for a tank which doubles up as a piece of art, this one from City Aquarium is a real catch. The aquarium uses a hand-sculpted reef and bright rainbow fish to add colour and life to the room. It also has a cabinet beneath for optimising small-space storage – result!

Aquariums add an air of calm to the often manic kitchen space, and you’ll be fishing for compliments from friends with an installation like this one from Phil Kean Designs. It’ll have you feeling cool and collected instead of crabby during stressful meal prep moments.

What really makes this super-cool aquarium is how it naturally accents its environment. Don’t you think the pairing of the tank’s lighting with the ceiling chandelier is utterly sublime? We definitely want our dining room to look this good!

Mixing a classical column and a huge aquarium takes skill and a lot of dough. Gaudy and audacious yet still hypnotically stunning, do you love it or hate it?

If you want to chase waterfalls, then you’ll also fall for this spooky koi pond. Okeanos Aquascaping has modernised traditional Japanese decorative features for this obscure aquarium. It’s a little hard to see the fish from the image, but they’re in there – perhaps they’re a little koi...

You’ll never want to sit at a proper table again after seeing this high-stooled bar with a dark and captivating aquarium at its heart. Breakfast, brunch or late-night drinks – whatever the occasion, you’ll want it to take place here.

Who’d have imagined you’d find tropical fish tanks in the desert ranges of Utah? This residential project by Markay Johnson Construction features another stellar aquarium bar fit for a millionaire or Hollywood star(fish). We’ll drink to that!

However, if you’re searching for something a little less low-key in your house (as if a home aquarium could ever be subtle!), Underwater Creations Inc. custom-made this fantastic tiki bar, which will make your tropical fish feel like they're back in the wild.

Outer space may seem oceans away from the deep blue sea but the concepts marry beautifully in this Battlestar Galactica-inspired, 15-foot long koi tank. While you may think the fibre optic lighting is cool enough, the fish themselves are also out-of-this-world: these platinum ogon koi have colour-changing scales!

This Berlin loft got a facelift following the installation of this titanic saltwater reef aquarium. You’ll have to have a big net worth to be able to afford something like this! 

Sometimes aquatic aficionados want to take construction into their own hands, which is exactly what Jack Heathcote from Nottingham did when he built Britain’s biggest home aquarium in his basement. His roommates were fairly horrifying, including three two-foot-long pacus (biting fish with human-like teeth), a redtail hybrid catfish, two alligator gars, eight enormous stingrays and two turtles. However, this notoriously expensive hobby meant Jack had to close his aquarium due to the astronomical upkeep costs.

So what are you going to do if you want your aquarium to be given pride of place in your property and not buried down in the basement? Put it where everybody will see it: installing a tank in your entrance way – à la this custom build – will really make waves.

For the lovers of streamlined design, this aquarium brings a fresh splash of nature into a busy London townhouse. We are obsessed with the beautiful sapphire and emerald colour scheme and the copious storage space in these bespoke cabinets.

New Jersey-based architects and designers Electronics Design Group have engineered seriously one of the most incredible home aquariums we’ve ever seen – not even squidding! The heart of the home is this very grand 15,000-gallon Roman-themed saltwater fish tank filled with species native to the area – many of which the fishing-mad owner reeled in himself. It's definitely one of the most jaw-dropping home features money can buy. 

This aquarium in Haifa, Israel looks pretty large, right? Local wildlife enthusiast Eli built it so he could relax and enjoy watching his favourite fish at home. Talk about getting carried away with the idea, it spans the entire width of his living room wall!

Eli doesn’t flounder about: the aquarium holds 10,000 gallons of water and is so huge that he and his sons can climb in and swim around with their marine cohabitors. Scuba diving gear necessary!

To give you an idea of just how large Eli’s tank is, this whopping aqua house constructed by Seavisions Aquariums holds only 1,700 gallons of water but with its curved frontage and skilful lighting, we think that it's just as beautiful. Featuring two-inch glass to withstand any water pressure, it's an ideal centrepiece for your in-house watering hole.

This fluvial headboard was constructed for a furniture store in North Carolina by the team behind the Animal Planet reality show Tanked. If you want to sleep with the fishes, waterbeds don’t come much posher than this!
