On the Ayrshire coastline, a new chapter is being written by the RAD Group at Seamill Hydro – and it’s being told entirely through design. The recent launch of Tides and Sirens represents a masterclass in experiential hospitality – two spaces that don’t merely house an experience, but become it.
The project’s central ambition was to dissolve the boundary between interior and landscape. That vision was only realisable through the strength of the partnerships behind it. Working closely with Studio Two on the interior design concept, and with Blairs Aluminium delivering precision fabrication and metalwork throughout both venues, the project reflects what becomes possible when hospitality ambition and specialist craft align.
Every material choice, lighting decision and spatial arrangement has been made in service of a single idea – that guests should feel the presence of the Firth of Clyde whether they’re seated at a breakfast table or nursing a late-night cocktail.

The more expansive of the two spaces, Tides, anchors the concept. Replacing the former Orangery, the 180-cover all-day dining room is defined by its floor-to-ceiling glazing, which frames the coastline like a living canvas.
The interior language mirrors the view beyond it: curved banquettes echo the sweep of a shoreline, soft contours suggest the pull of a current, and layered textures shift with the quality of the light outside.
A coastal-informed palette draws on the ever-changing tones of the Firth – the grey-greens of a stormy morning, the warm amber of a west-coast sunset.
Tides, the hotel’s new all-day dining restaurant, now serves a menu of modern Scottish flavours and is led by head chef Andrew Heaney, who has crafted a locally sourced menu full of classic dishes and signature showstoppers, such as the decadent Scottish seafood two-tier tower, made to share.
Yet it is perhaps the commission of a bespoke artwork that most boldly declares the design intent.
Stretching across one wall, a custom underwater mythological mural transforms what could have been a passive backdrop into a dramatic focal point – mythology made material, the sea brought indoors.
One of Tides’ most distinctive design features is a custom-designed underwater mythical mural, which serves as a dramatic focal point in the restaurant.
This artwork complements the luxurious interiors and soft, coastal-inspired colour palette, offering a modern and comfortable dining experience.

Crucially, the design was conceived not as a fixed scheme but as a responsive one – a space engineered to change character as the day progresses.
Tides has been designed to give guests a unique experience each time they visit. Echoing the moon’s influence on the sea, the beautiful interiors mirror the movement of water, with a buzzing social atmosphere as you watch day or night go by.
From crashing waves during breakfast to sunsetlit dinners, the changing tides of the Firth of Clyde provide sweeping views and an ambience you won’t find anywhere else. Where Tides is defined by scale and luminosity, Sirens was conceived as its deliberate counterpoint.
Positioned adjacent to the restaurant, the new Champagne and cocktail lounge draws guests inward – through a threshold that is itself a design statement an illuminated archway into a speak-easy-inspired space.
Sirens, the new intimate Champagne and cocktail lounge, is adjacent to the Tides restaurant.
Accessed through an illuminated archway that opens into a stylish, speakeasy-inspired space. That archway functions as more than a passageway — it is a scene change.
The architecture shifts register immediately: materials grow richer, the palette deepens, and the spatial proportions become more enveloping. Lighting, carefully layered and precisely controlled, does the heaviest design work here, modulating the atmosphere from afternoon ease to late-night theatre.

A central statement bar anchors the room, while elaborate ceiling detailing adds verticality and intrigue to what is otherwise a deliberately cocoon-like environment. The conceptual references – sirens, lunar mythology, the seductive pull of the deep – are embedded into the spatial DNA rather than applied as surface decoration. For all its mood and enclosure, Sirens never loses sight of the landscape that inspired it.
Sirens offers guests a beautifully designed space to gather, unwind and extend the experience before or after dining at Tides. Together, the two spaces are best understood as a single design argument made in two movements – from the panoramic to the intimate, from daylight to candlelight, from the natural world to the mythological. That pairing was by design.
Aaron Kyle, Director RAD Hotel Group comments, “A long time in the making, we’re absolutely delighted to open Tides and Sirens as part of a new food and drink offering at Seamill Hydro. It was our vision from the outset to create two distinctive destination venues that feel special in their own right, while making the most of this incredible coastal setting on our doorstep.
“Tides offers a truly memorable dining experience centred on quality Scottish produce and magnetic sea views, while Sirens brings new energy to the resort with a beautiful space to unwind, celebrate and connect with friends or loved ones over cocktails, Champagne or small plates. It gives us great pleasure to welcome both guests and local visitors to experience these special venues for themselves.”
