The Brief
Project Overview
TATTA is Woodlam’s first full-scale modular prototype, developed in collaboration with Svetlin Petrov of Kousou Jakarta. Constructed within the JIEP Industrial Estate in East Jakarta, the 84 m² structure was completed in two weeks as a live research and development model.
The prototype was designed to demonstrate that prefabrication can deliver speed, structural clarity, and architectural warmth without compromise.
Objective
The objective was to validate a modular glulam system capable of:
Rapid assembly through prefabricated components
Seismic-responsive structural logic suitable for Indonesia
Layout flexibility for residential and commercial use
Replicable production through standardised modules
TATTA was conceived as both a prototype and a scalable system.
The Constraints
Two-Week Construction Timeline
The full prototype had to be fabricated and assembled within a compressed development window.
Prefabrication Discipline
All panels, joints, and modules required pre-resolution prior to site assembly.
Seismic Performance Requirement
As a proof-of-concept system, structural behaviour under lateral forces had to be considered from the outset.
Market Adaptability
The system had to remain flexible enough for multiple configurations without redesigning core structural elements.
The Engineering
Modular Glulam Structural Frame
Jabon glulam members were dimensioned for efficient load transfer while remaining manageable for prefabrication logistics.
Strength-to-weight optimization improves scalability.
Panelized System Architecture
Structural elements were divided into repeatable modules. Each module integrates beams, panels, and connection interfaces for predictable assembly.
Modularity enables replication.
Seismic-Responsive Detailing
Connections were detailed to allow controlled flexibility under lateral movement. Lower structural mass reduces seismic force, while elastic behavior dissipates energy.
Movement is absorbed, not resisted through excess weight.
Pre-Drilled Mechanical Interfaces
All fastening coordinates were resolved in advance. Factory drilling eliminated guesswork and reduced installation variability.
Precision reduces on-site dependency.
Replicable Production Workflow
Fabrication followed a repeatable process rather than a custom build sequence. Standardization strengthens scalability for future deployment.
The Products and Materials
The Results and Insights
Two-Week Completion Achieved
The prototype demonstrated that disciplined prefabrication can significantly reduce on-site construction time.
Seismic Logic Validated
Structural detailing reinforced timber’s suitability for earthquake-prone regions through controlled flexibility.
Scalable Modular Framework Established
TATTA provided a clear blueprint for future modular residential and commercial deployment.
Speed Without Compromise
The project reinforced a core principle: speed must be guided by precision, not urgency.

Frequently Asked Questions
Got a question unanswered? Speak to our team.
What makes TATTA different from conventional timber construction?
TATTA was engineered as a fully prefabricated modular glulam system with repeatable structural panels and pre-resolved connection detailing. Unlike conventional timber construction that relies on site interpretation, geometry and fastening logic were resolved before fabrication, enabling rapid, controlled, and scalable assembly.
Is the system suitable for seismic regions?
Yes. The glulam frame and connection detailing were designed to support controlled flexibility, improving resilience in earthquake-prone environments.
Can the prototype be adapted for different layouts?
Yes. The modular logic allows flexible interior configurations without redesigning the primary structural framework.
What did TATTA prove for Woodlam?
It proved that prefabricated glulam systems can deliver speed, scalability, and structural intelligence simultaneously when fabrication discipline and modular logic are integrated.
