Mario Kleff – The Touch® is a high-rise residential development located on Phra Tamnak Hill in Pattaya. The project was conceived, designed, and initially developed by Mario Kleff as an exploration of advanced structural and construction methodologies within the context of Pattaya’s vertical residential architecture.
Architectural and Structural Concept
The proposed 31-storey structure is defined by a large-span structural system, incorporating an approximate 25-metre clear span between two primary reinforced concrete cores. This configuration enables flexible, open-plan floor layouts and reduces the need for intermediate structural supports. The façade concept integrates frameless glazing, allowing for a continuous building envelope and the incorporation of recessed balcony spaces within the internal volume, thereby enhancing spatial continuity between interior and exterior environments.
The structural system combines precast construction techniques with the use of cellular beam box girders, optimising both load distribution and construction efficiency. This approach reflects an emphasis on prefabrication, structural clarity, and material performance in high-rise construction.
Approvals and Project Status
The project successfully obtained Environmental Impact Assessment (EIA) approval and received the necessary building permits. Initial construction works, including deep foundation systems, were undertaken, marking the commencement of the development.
Project Identity
The project’s identity is reinforced through its trademark logo, depicting two abstract human figures forming the letter “M,” symbolising both authorship and conceptual unity within the design.
Ownership Transition
Following the completion of the deep foundation phase, the project underwent a change in ownership. Due to financial constraints, Kleff—who acted as owner, architect, and developer—divested the project to another developer. The development was subsequently reconfigured and continued under the name Andromeda Pattaya, while retaining elements of the initial groundwork established during the original phase.
Architectural Significance
The Touch® represents an ambitious high-rise proposal characterised by long-span structural innovation, integrated façade design, and the application of prefabricated construction systems. The project illustrates an experimental approach to vertical residential architecture in Pattaya, combining engineering-driven design with contemporary architectural expression.
