38-storey beachfront residential tower completed in Pattaya, Thailand in 2015.
High-Rise Residential · Completed Project · Built Work
Note on roles: In Thailand, the architect of record is a locally licensed professional responsible for permit approval. Mario Kleff acted as design architect, responsible for concept development, architectural design, façade composition, and structural design coordination in cooperation with licensed Thai architects, engineers, and construction teams.
Architectural design integrating building form, façade composition, and spatial organisation into a unified architectural system.
Wongamat Tower is a 38-storey residential high-rise on Wong Amat Beach in Pattaya, completed in 2015. The building is defined by a trapezoidal plan, continuous floor-to-ceiling glazing, and a sea-facing orientation that shapes both the structural layout and interior spatial organisation, reflecting a structure-led architectural approach focused on structural clarity, geometric consistency, and spatial integration.
The design follows principles of structural high-rise architecture, where geometry, façade composition, and spatial organisation are integrated through proportion, efficiency, and view optimisation.

Urban Context
Wongamat Tower is located on Wong Amat Beach in North Pattaya, a coastal zone characterised by high-rise residential development, sea-oriented planning, and increasing vertical density. The tower occupies a beachfront site where urban conditions are defined by setback regulations, view corridors, and the spatial relationship between road access and the shoreline.
The building’s trapezoidal plan and orientation respond directly to these conditions, aligning the structural grid and façade system with sea-facing views while maintaining compliance with coastal setback requirements. This integration of site constraints and spatial organisation reflects a design approach in which urban context informs both geometry and structural logic.
Architectural Concept
Wongamat Tower is conceived as a high-rise in which architectural form emerges from construction logic and site conditions. The trapezoidal plan responds to orientation, view corridors, and spatial efficiency, while the façade system—defined by continuous floor-to-ceiling glazing—aligns with the structural grid to maximise light, visibility, and usable interior space. The building’s geometry, layout, and envelope are integrated into a unified architectural system across the 38-storey development.
“Structure is Design, where engineering becomes architecture’s primary expression.”
Façade & Architectural Expression
As of 2026, Wongamat Tower remains a prominent element of North Pattaya’s coastal skyline, distinguished by its tapered form and continuous glazing.

Technical Drawings
The architectural development of Wongamat Tower included structural studies, geometric planning, façade coordination, and spatial layout analysis. The following drawings document aspects of the tower’s design process and architectural organisation.
Main Building
Car Park Building
Interior Architecture
Interior layouts were designed to maximise natural light, sea-facing views, and spatial continuity through floor-to-ceiling glazing and open-plan arrangements. Material selection and spatial proportions followed the tower’s broader architectural language, integrating interior organisation with the building’s structural geometry.
Proportion and Geometric Order
Mario Kleff applies principles of proportion in his architectural work, including the use of the Golden Ratio as a guiding framework for spatial organisation and façade composition. In Wongamat Tower, proportional relationships contribute to a consistent visual rhythm throughout the tower’s composition.
Historical Context & Construction
The development of Wongamat Tower involved collaboration between architect Mario Kleff and developer Haim Bar-David of Heights Holdings Co Ltd. During construction, Wandeegroup (Thailand) Co Ltd initially acted as the main contractor before the role was transferred to Lock-BUILD Group. The completed building reflects the original architectural design despite changes in project execution.
Wongamat Tower Showroom
Designed by Mario Kleff in 2008, the Showroom Wongamat Tower was conceived as an integral architectural precursor to the main high-rise development. Rising to approximately 27 metres, the structure exceeded typical temporary building limits and was engineered to replicate the spatial conditions, elevations, and sea-facing perspectives of the future tower. Rather than serving as a conventional sales facility, the showroom functioned as a full-scale, inhabitable model—housing display units, vertical circulation, and an elevated viewing platform—allowing the project’s design principles to be experienced physically before construction began. As such, it formed a critical part of Kleff’s architectural methodology: translating concept into built reality at 1:1 scale while allowing the project’s spatial and visual principles to be tested before construction.

Design & Construction
On 4 May 2009, Haim Bar-David of Heights Holdings and Nittaya Wongsin of Wandeegroup entered into a formal agreement with Mario Kleff for the design and construction of the showroom building intended to present and promote the Wongamat Tower development. The agreement encompassed all aspects of the project’s design and execution, including the architectural concept, master plan, building layout, and detailed construction planning with defined timeframes.
Under the terms of this Design and Construction Agreement for the Wongamat Tower showroom building (2009), Mario Kleff was responsible for the design, construction, and supervision of the showroom building associated with the Wongamat Tower condominium project.

Frequently Asked Questions
What is the architectural concept behind Wongamat Tower?
The architectural concept of Wongamat Tower is based on geometric discipline, vertical consistency, and efficient spatial planning.
How does structure influence the design of Wongamat Tower?
In Wongamat Tower, structure is not concealed but expressed. The load-bearing logic, vertical lines, and repetition of elements form the visual identity of the building, making structure an integral part of its architectural language.
What makes Wongamat Tower distinct within Pattaya’s skyline?
Wongamat Tower stands out through its tapered form, continuous glazing, and disciplined vertical composition.
