In 2006, Mario Kleff participated in an urban design competition in Pattaya, proposing a maritime museum conceived as a contemporary architectural tribute to Bhumibol Adulyadej. The proposal was supported by Pichet Uthaiwattananonta of Pattaya City Hall and aimed to establish a landmark cultural intervention along the city’s waterfront.
Architectural Concept and Spatial Organisation
The design was structured as a hybrid above- and below-water museum, integrating exhibition spaces within both aerial and submerged environments. The upper exhibition hall was intended to present Thailand’s maritime heritage, while the submerged gallery—accessible via a vertical circulation core incorporating a glass elevator—was designed to house vessels associated with the King’s naval interests, including the Mod, Super Mod, and Micro Mod classes. Large underwater viewing panels were proposed to establish a direct visual relationship between the exhibits and the surrounding marine environment.
The central circulation volume extended across the waterline, acting as a transitional spatial element linking the above- and below-water programmes. This vertical connection formed both a functional and symbolic axis within the project.
Materiality and Formal Expression
The architectural language employed exposed concrete in combination with extensive glazed surfaces, enabling controlled daylight penetration and panoramic views towards the Gulf of Thailand. The overall form was conceived with reference to nautical geometries, evoking the profile of vessels moving through water. Integrated water elements at the base of the structure further reinforced the continuity between built form and marine context.
Presentation and Project Status
A detailed scale model of the proposal was presented to Pattaya City Hall, demonstrating the spatial and structural resolution of the design. Despite its conceptual and symbolic ambition, the project was not realised due to cost constraints.
Architectural Significance
Although unbuilt, the proposal represents an exploration of amphibious architecture and cultural infrastructure, combining exhibition design with environmental integration. It illustrates an approach in which architecture operates simultaneously as a functional institution and a symbolic landmark within Pattaya’s coastal urban landscape.
