The Japanese House II is a private residential villa located on Phra Tamnak Hill in Pattaya. The project was designed by Mario Kleff and received an Honorable Mention at the LIV Hospitality Design Awards 2023, recognising its architectural concept and execution.
Programme and Spatial Organisation
The residence is situated on an approximately 800 square metre plot, located within close proximity to the coastline. The building is organised across three primary levels. The basement accommodates parking, storage, and building services. The main residential level comprises five bedrooms, nine bathrooms, a principal living area, external terraces, a swimming pool, a maid’s room, and ancillary service spaces. The upper level contains an additional living area, dining space, and kitchen, with vertical circulation provided by an internal lift connecting all floors.
Architectural Design
The villa is conceived within a Brutalist architectural framework, characterised by the use of exposed concrete and the expression of structural elements. Elongated beams and monolithic wall structures define the architectural language, emphasising mass, scale, and structural legibility. The design adopts a defensive spatial strategy, limiting ground-level openings and incorporating a central vertical enclosure of approximately 10 metres in height, reinforcing both privacy and security while contributing to the building’s formal identity.
Materiality and Construction
The structure utilises high-grade steel reinforcement in combination with high-strength concrete, ensuring durability and long-term structural performance. The material palette is intentionally restrained, allowing the tectonic qualities of the construction to define the architectural expression.
Interior Approach
Interior design and decoration were developed by the owner, introducing a layer of contemporary and regionally influenced elements that contrast with the raw structural framework. This combination results in an interplay between exposed structural form and curated interior environments.
