The Brief
Project Overview
Sedayu House is a 300 m² private residence in Kelapa Gading, North Jakarta, designed by TMM Studio. The project reimagines the traditional Javanese joglo roof using modern engineered timber systems.
Woodlam delivered a Jabon glulam structural frame paired with European White Oak VPanel interiors. Completed in approximately 1.5 months, the project required structural recalibration to reinterpret heritage geometry within contemporary residential performance standards.
Objective
The objective was to translate traditional joglo proportions into a structurally efficient engineered system by delivering:
Broad roof spans using glulam instead of conventional solid timber
Controlled load distribution for elevated roof mass
Warm interior surfaces through oak VPanel integration
Accelerated build timeline without structural compromise
The Constraints
Traditional Roof Geometry
The joglo form concentrates roof mass and structural forces toward central supports. Reinterpreting this with glulam required careful load-path analysis.
Urban Residential Context
The house sits within a dense Jakarta neighbourhood. Structural members had to be dimensioned for controlled transport and assembly.
Compressed Installation Timeline
The structural and interior systems were completed in under two months, requiring coordinated prefabrication and sequencing discipline.
Material Integration Across Systems
Structural glulam and interior VPanel systems had to align visually and proportionally to maintain architectural coherence.
The Engineering
Jabon Glulam Structural Frame
Laminated Jabon beams improved load distribution compared to traditional solid timber joglo construction.
Recalibrated Load Distribution
Structural calculations redistributed roof mass more efficiently, reducing concentration at central supports.
European White Oak VPanel Integration
Interior surfaces used stabilized oak panels to maintain dimensional control across walls and ceilings.
Prefabrication and Sequencing Control
Structural members were pre-cut and pre-drilled to reduce site variability and accelerate erection.
The Products and Materials
The Results and Insights
Joglo Geometry Successfully Modernised
The roof achieved traditional spatial presence with engineered structural clarity.
Rapid Delivery Confirmed
Completion within 1.5 months demonstrated the efficiency of prefabricated glulam systems in residential builds.
Heritage and Engineering Aligned
The project validated that cultural architectural language can be translated into modern structural systems without superficial imitation.
Structural Complexity Managed
Sedayu House reinforced Woodlam’s capability in balancing roof weight, span optimisation, and interior integration within compact urban sites.

Frequently Asked Questions
Got a question unanswered? Speak to our team.
Why use glulam instead of traditional solid timber for a joglo roof?
Glulam improves structural consistency, reduces natural defects, and allows controlled span performance. It offers greater predictability compared to solid timber, especially for larger roof structures.
How was roof weight managed in this project?
Through load-path recalculation and beam optimisation. Laminated members distribute structural stress more evenly, reducing unnecessary mass concentration.
How did the project achieve a rapid build timeline?
By resolving structural geometry in advance, prefabricating key members, and coordinating installation sequencing. Speed resulted from preparation rather than rushed execution.
Why is this project strategically important for Woodlam?
Sedayu House demonstrates Woodlam’s ability to reinterpret Indonesian architectural heritage through engineered timber systems. It bridges tradition and modern structural discipline in a repeatable way.
