Mayfair Piranha Aquarium

From concept to living piranha masterpiece.

This project quickly became one of our team’s favourites. 
It is a striking 4.2 metre long freshwater aquarium built in collaboration with one of our long standing clients. It now sits at the heart of a newly opened luxury restaurant in St James, quietly dividing the restrooms with an unexpectedly wild twist: a shoal of over 40 freshwater Piranhas.

Design

The aquarium serves a dual purpose as a visual centrepiece and a room divider. Its size and placement immediately catch the eye, giving the illusion of a suspended river running through the space above a run of bespoke sinks.

The layout of the aquascape was inspired by the tangled root systems of the Amazon’s mangroves, the natural habitat to these Piranhas. The design uses real wood forms, dark substrates, and soft, directional lighting to echo the moody tones of the venue’s interior, while also providing the fish with the structure and cover they need to feel secure.

Installation

Set between structural concrete pillars, what makes this installation especially unique is the way it appears to float with no visible support framework beneath.

To achieve this, careful pipework routing keeps everything discreet, and access panels are hidden in the finishes. All filtration and technical components are tucked away in a custom service room on the same floor, keeping the complex mechanics completely out of sight.

Maintenance

Because all filtration and technical components are tucked away in a custom service room, it allows most maintenance work to be done without interrupting the flow of the space, or the guests using it.

Careful pipework routing keeps everything discreet, and access panels are hidden in the finishes. Despite their reputation, these Piranhas coexist peacefully in a large, carefully managed group. They're hand-fed daily, and it's clear they’re growing well and thriving together.

Good to know

Why are some points pending?

Purchase points have an approval period before they become available. Your balance shows available points separately from pending points.

How long do my points last?

When points expiry applies, your balance stays valid for 365 days from qualifying rewards activity. Earning eligible rewards, redeeming points or a balance adjustment renews that window. Simply visiting the shop does not renew it.

Can I use points with my stamp reward?

Yes. Add your 10% stamp reward code at checkout and switch on your points. Your final saving depends on the eligible product total and any other discount restrictions.

What happens if I return something?

Earned points are adjusted for returns. Points used on refunded products are restored proportionally. If a refund takes a qualifying order below £250, its stamp is removed.
