On The Hill is a proposed condominium development located on Pratumnak Hill in Pattaya. The project was designed by Mario Kleff as a low-density residential scheme with an emphasis on spatial layout and construction specification.
Architectural Concept
The design incorporates principles associated with Bauhaus and Nordic Functionalism (Funkis), with an emphasis on clarity of form and functional planning. The architectural composition includes extensive glazing to increase natural light, together with triple balconies for each apartment. A rooftop swimming pool was included as part of the shared building facilities.
Materiality and Interior Approach
The interior concept combines natural and industrial materials, including hardwood, leather, granite, and glass, alongside concrete, aluminium, and steel elements. The design incorporates open-plan layouts across 31 residential units, with features such as spiral staircases and integrated furnishings. Elements associated with Zen spatial planning were referenced in the interior layout.
Project Status
The development received building permits but was not realised. The proposal represents a low-density residential scheme within Pattaya’s hillside context, incorporating architectural and material strategies derived from modernist design principles.
