In 2009, Mario Kleff presented a proposal to the Construction Department of Pattaya City Hall for a gateway structure and pedestrian bridge located along Sukhumvit Road in North Pattaya. Conceived as a landmark urban intervention, the project was intended to function as a symbolic entrance to the city. Despite its conceptual ambition, the proposal was not realised due to cost considerations.
Architectural Concept and Design Language
The design is characterised by a sculptural architectural approach, combining expressive form-making with structural intent. The primary composition consists of three large, curved vertical elements, evoking wave-like geometries, which support a series of metallic dolphin sculptures referencing Pattaya’s coastal identity. Above, a circular structural element incorporates an abstracted sun motif and integrated “WELCOME” lettering, forming a visually prominent gateway marker.
The pedestrian bridge extends across the highway as a sharply defined, linear structure, contrasting with the fluidity of the primary monument. Its design adopts a restrained material palette of steel and glass, with integrated signage displaying “PATTAYA,” ensuring legibility at an urban scale while maintaining formal coherence with the overall composition.
Structural Concept and Engineering Considerations
The proposal required the integration of advanced structural systems to support both the elevated pedestrian bridge and the cantilevered sculptural elements. The design strategy combined reinforced concrete substructures with high-strength steel framing to achieve the necessary spans and load distribution. Particular attention was given to the visual effect of suspended or “floating” elements, requiring precise engineering coordination between structural supports and architectural form.
Architectural Significance
Although unbuilt, the project represents an exploration of civic-scale architecture that merges infrastructure with symbolic urban identity. It illustrates an approach in which structural engineering, sculptural form, and place-specific references are synthesised into a singular architectural gesture, intended to define a recognisable gateway to Pattaya.
