Monaco-based design studio Lagaria, founded by Magnus Naglestad and Adeline Lagaria, has unveiled a bold new 90-metre superyacht concept named Platea — a design that challenges conventional yacht architecture by radically prioritising exterior living space.
Conceived around a simple guiding principle — that the best experience onboard happens outside — Platea rethinks traditional yacht layout hierarchy and shifts focus away from enclosed volume toward expansive, functional open-air environments.
A New Spatial Philosophy
Unlike conventional superyacht layouts, Platea introduces an inverted design logic, where exterior decks are treated as the primary living environment rather than a complement to interior spaces.
The centrepiece of the concept is the main deck, described by the designers as a “floating beach club of unusual generosity.” Starting aft, it features an open-plan bar, lounge, and dining area that flows seamlessly into a vast protected midship terrace.
This central zone includes:
- An oversized swimming pool
- A jacuzzi
- A full-service outdoor bar
- Large flexible spaces designed for social events
From casual daytime use to large-scale entertainment, the deck is designed to operate as a continuous social landscape.
Lower Deck Living, Upper Deck Freedom
In a significant departure from standard yacht arrangements, all guest accommodation is placed on the lower deck, deliberately freeing up prime exterior areas for shared experiences throughout the day.
The design philosophy is clear: valuable volume is not reserved for private cabins, but instead dedicated to spaces where guests spend most of their time.
Meanwhile, the owner’s suite is positioned aft as a private apartment, complete with its own balcony, ensuring privacy while maintaining direct connection to the sea.
Another distinctive feature is the placement of the bridge aft of midship, inspired by Scandinavian well-boat design principles.
This repositioning:
- Unlocks additional central deck space for social use
- Improves operational visibility via wing stations
- Reduces enclosed superstructure volume
- Reinforces the yacht’s open, horizontal architecture
A helipad is also integrated on the foredeck, ensuring efficient arrival and departure access.
Efficiency Through Design
According to Lagaria, Platea achieves approximately 20% lower gross tonnage than comparable 90-metre yachts, despite offering extensive outdoor social space.
The studio argues that future charter demand will be driven less by interior volume and more by experiential quality and spatial intelligence.
As the founders explain, a more efficient spatial hierarchy can generate higher charter value per GT, even with reduced internal volume — a concept that directly challenges traditional superyacht economics.
A Different Way of Thinking About Yachts
Lagaria’s vision for Platea represents a shift in design philosophy rather than incremental evolution. The yacht is not defined by size or volume, but by how space is experienced, used, and shared.
As the studio concludes, the concept “looks like nothing currently on the water, because it was designed from an entirely different set of questions.”
Platea positions itself as a new interpretation of the 90-metre segment — where exterior living, social architecture, and efficiency redefine what luxury at sea can mean.
