The Brief
Project Overview
JT House is a 700 m² private residence in Tangerang designed by Studio TonTon. Overlooking a golf course, the project required a façade that introduced warmth and subtle rhythm without disrupting the home’s modern architectural clarity.
Woodlam delivered an Accoya Timberclad system across façade and courtyard edges, integrating engineered timber within a highly detailed, multi-vendor residential build.
The Objective
The objective was to validate high-performance exterior timber within a precision-driven residential context by delivering:
Dimensional stability under tropical humidity
Subtle façade articulation through repeatable cladding rhythm
Seamless coordination with glazing, stone, and metal trades
Long-term durability without visual distortion
The Constraints
Multi-Trade Coordination
Alignment across glazing, steel, and masonry required sequencing precision.
Urban Façade Exposure
Rainfall and humidity demanded durable, dimensionally stable cladding.
Minimalist Sensitivity
Board spacing and shadow gaps allowed no visual correction.
Refined Residential Expectations
Surface finish and grain continuity required high-end execution discipline.
The Engineering
Accoya Timberclad System
Accoya was selected for acetylated dimensional stability, reducing swelling and shrinkage under humidity fluctuation.
Calibrated Spacing Modules
Cladding boards were installed using consistent spacing intervals to maintain shadow-line discipline across long facade runs.
Ventilated Assembly Strategy
Ventilation gaps and sealed interfaces were integrated to reduce moisture retention and protect the rear of boards.
Trade Interface Coordination
Junctions with glazing and masonry were pre-resolved to prevent tolerance conflicts during installation.
The Products and Materials
The Results and Insights
Facade Rhythm Maintained
The cladding system achieved consistent spacing and clean edge termination, reinforcing architectural clarity.
Durability in Tropical Conditions Confirmed
Accoya’s modified structure demonstrated strong resistance to movement and surface distortion.
High-Level Vendor Coordination Validated
The project strengthened Woodlam’s ability to operate within complex residential builds involving multiple contractors.
Quiet Precision as Identity
JT House reinforced a core principle: in refined residential architecture, restraint demands greater technical discipline, not less.

Frequently Asked Questions
Got a question unanswered? Speak to our team.
Why was Accoya selected for this façade?
Accoya is acetylated timber engineered for high dimensional stability and resistance to moisture. In tropical climates, this reduces expansion, contraction, and long-term distortion compared to untreated species.
What makes façade coordination complex in private residences?
Residential projects often involve multiple trades working in parallel. Cladding alignment depends on precise interface detailing with glazing, steel, and masonry. Without sequencing control, tolerance stacking becomes visible.
How is long-term stability ensured in timber cladding?
Through correct species selection, concealed fixing strategy, ventilation detailing, and moisture management. Stability is achieved by engineering the system, not relying solely on material quality.
Why is this project strategically important for Woodlam?
JT House represents one of Woodlam’s most refined Accoya façade applications. It strengthened capability in high-end residential coordination, façade rhythm control, and engineered durability within complex urban builds.
