size
210 m²
The Brief
Omah Jati in Anyer was designed by Studio Andra Matin in collaboration with SKP and engineered by Woodlam.
Located inside an existing teak forest, the project was executed under a strict condition: no trees could be removed.
Woodlam engineered and installed a glulam structural frame, Timberclad wall systems, Timberdeck walkways, and VPanel elements using a calibrated multi-species strategy.
The 210 m² retreat was completed in approximately two months.
This project marked a shift in Woodlam’s evolution from timber supplier to integrated construction system partner.
The Constraints
Total Tree Preservation
All standing teak trees had to remain untouched.
Structural geometry could not follow a rigid grid. Column placement, beam spans, and deck openings were adjusted around existing trunks.
Engineering had to respond to nature, not override it.
Root System Protection
Foundation placement was restricted to avoid root damage.
Heavy equipment access was minimized to prevent soil compaction.
This required:
• Smaller-scale equipment
• Controlled sequencing
• Real-time structural adjustment
Coastal Humidity and Rainfall
The site experiences:
• High humidity
• Salt-laden coastal air
• Tropical rainfall
Species selection and detailing were critical for long-term durability.
Irregular Clearances
Beam alignments and structural tolerances had to be adjusted on site due to irregular tree spacing.
Precision had to coexist with unpredictability.
The Engineering
Adaptive Structural Frame
Glulam beams and columns formed the primary load-bearing system. Member placement was engineered around existing teak trees, with load paths recalculated for irregular spacing rather than a rigid grid.
Multi-Species Performance Strategy
Species selection followed exposure and durability logic, not visual preference. Higher-durability timbers were allocated to weather-facing zones, while structural and protected interior zones used species optimized for strength and stability.
This allowed the project to combine structural performance and long-term durability without over-specifying a single timber type.
Elevated Durability Detailing
Timber elements were elevated above ground to reduce moisture transfer, increase airflow, and limit termite risk. In tropical construction, physical separation from soil is a primary durability mechanism.
Sequenced Prefabrication
Structural components were prefabricated to increase speed and reduce field interpretation. Installation sequencing was adjusted on site to accommodate environmental constraints while preserving structural integrity.
The Products and Materials
The Results and Insights
Environmental Integration Achieved
Omah Jati demonstrated that engineered timber systems can adapt to living landscapes without requiring site clearance.
Structural precision was maintained despite irregular geometry.
Multi-Species Logic Validated
Assigning timber species based on exposure and performance improved durability outcomes and material efficiency.
The project reinforced Woodlam’s species-performance mapping approach.
Coastal Durability Strategy Strengthened
Elevated detailing and appropriate species allocation mitigated moisture and termite risks in a forested coastal environment.
Construction System Maturity
This project marked Woodlam’s shift toward full construction system coordination, integrating structural engineering, environmental protection, fabrication, and on-site adaptation.

Frequently Asked Questions
Got a question unanswered? Speak to our team.
Were any trees removed during construction?
No. All existing teak trees were preserved. Structural elements were positioned around trunks and root systems. Deck openings and beam alignments were adjusted to maintain full tree retention.
How was durability handled in a coastal forest environment?
Species were selected based on exposure and structural demand. Higher durability hardwoods were used for exterior zones, ironwood shingles for roofing, and all structural members were elevated to reduce moisture transfer and insect exposure. Durability was achieved through species logic and detailing discipline.
Why use multiple timber species in one project?
Different zones experience different environmental loads. Structural elements require predictable strength and machinability. Exterior surfaces require higher durability and resistance to moisture and insects. Performance-based species allocation improves longevity and efficiency.
Why was Omah Jati strategically important for Woodlam?
It required structural engineering to adapt dynamically to a preserved natural site. The project strengthened Woodlam’s ability to integrate timber systems within environmental constraints while maintaining construction speed and structural discipline.
