Completed projects built from CLT panels.
A reception office fully built from CLT and Glulam.
The Lucca Resort reception office shows how engineered timber can be used as both structure and finished architecture in a tropical Indonesian setting. CLT forms the main wall, floor and roof elements, while Glulam provides the larger structural members. The project was prefabricated for fast erection on Karimunjawa, where efficient transport and a short on-site construction period were especially important.
Watch the constructionOne of our early CLT projects, built with local Acacia and used every day with pride at UGM.
The CLT Nusantara Pavilion at the Faculty of Engineering, Universitas Gadjah Mada, is an early Indonesian example of locally engineered mass timber in daily use. Local Acacia is used as the structural timber, with CLT forming the main walls and floors. The pavilion functions as a meeting, showcase and learning space and demonstrates how timber construction can be combined with solar power, smart lighting and an IoT-supported garden. The project continues to be actively used by the university community.

The Tiny House demonstrates how CLT can turn a compact footprint into a warm, practical and highly prefabricated living space. The structure was prepared in timber, assembled as a complete showcase house and presented at the Synergy exhibition at PIK2 Jakarta. Its exposed wood interior, loft, stairs, integrated kitchen and bathroom show how structure and finished architecture can work together, while the roof-mounted solar panel highlights the potential for compact, sustainable buildings.
Several CLT units built as part of a residential complex in South Jakarta.
Kompleks Siaga Raya demonstrates CLT construction in a real residential setting in South Jakarta. Several units were built using prefabricated timber panels, with the construction sequence showing the raised foundation, rapid installation of wall panels and the timber roof structure. The completed buildings combine the CLT structure with a refined timber façade and landscaping, showing how mass timber can create warm, contemporary homes suited to Jakarta's tropical environment.
Four glamping units built with engineered timber in Bali's highland landscape.
The Bedugul project consists of four glamping units where engineered timber forms the warm architectural core of the accommodation. The construction and completed interiors show expressive timber walls, floors and structural elements combined with large curved openings, glazing, a mezzanine and custom stairs. The finished units pair the natural timber interior with the distinctive curved exterior shell, creating compact hospitality spaces closely connected to the surrounding Bali landscape.
A 3,600 mm-high CLT workspace created for a 3D printer and CNC machinery.
This warehouse project in Ngabul, Jepara, uses CLT to create a dedicated 3.6-metre-high workspace for digital fabrication equipment. The enclosed timber space was designed to accommodate a 3D printer and CNC machinery, demonstrating how CLT can be used not only for houses and hospitality projects, but also for practical industrial and production environments. The project also shows the panels themselves, their large-scale assembly and the precision possible when timber construction is combined with digital manufacturing.
Indonesia lives with earthquakes. BMKG recorded 7,443 earthquakes in 2024 — about 20 per day — including 752 felt events and 186 earthquakes of magnitude 5.0 or greater.
Most earthquakes are small, but even moderate shaking can leave cracks in brittle finishes and masonry, creating repair costs, safety concerns and frustration for building owners. CLT gives engineers a different way to design for seismic movement. Timber construction is relatively lightweight, reducing the inertial forces generated during an earthquake. Properly engineered CLT walls, diaphragms and connections can accommodate movement rather than relying on brittle behaviour. Advanced rocking-wall systems can even rock during strong shaking and be pulled back toward their original position by post-tensioned connections.
A full-scale two-story CLT research building underwent 13 earthquake tests and remained structurally damage-free. In 2023, engineers at UC San Diego also tested a full-scale 10-story, 35.5-metre mass-timber building under major earthquake simulations, including motions representing the magnitude 6.7 Northridge and magnitude 7.7 Chi-Chi earthquakes.
Less mass. Controlled movement. No heavy masonry walls breaking loose. A building designed to work with seismic movement rather than simply resist it.
Earthquake performance depends on the complete structural design. CLT panels alone do not make a building earthquake-proof. INCLT projects should be engineered for site-specific seismic conditions, foundations, connections and applicable Indonesian requirements.

CLT, cross-laminated timber, is an engineered wood panel built from layers of boards glued together at right angles under pressure, and it is quickly becoming the sustainable alternative to concrete and steel in construction. Its standout trait is an excellent strength-to-weight ratio: panel for panel, CLT is far lighter than concrete yet performs with comparable or greater strength, which opens up design possibilities heavier materials cannot match. Because trees absorb carbon dioxide as they grow, every CLT panel keeps that carbon stored for the life of the building instead of releasing it, and because panels are engineered components, whole structures can often be taken apart and reused rather than demolished. Buildings built from CLT tend to be healthier to live and work in, since timber surfaces help regulate humidity and avoid the off-gassing common in some synthetic materials, and the warm, visible wood grain gives interiors a naturally attractive finish that concrete cannot offer. That is why CLT is already a standard structural material for housing, offices and schools across Europe, North America and Australia, and why builders across Asia are adopting it fast as local supply catches up with demand. Beyond that core case, here are twelve more reasons the material keeps winning projects: (1) speed, since prefabricated panels arrive cut to size and go up in days rather than weeks; (2) fewer trades on site, because panels arrive with window and door openings already cut; (3) lower foundation costs, as a lighter structure needs less substructure beneath it; (4) factory-level dimensional accuracy, which cuts down on-site rework and waste; (5) a quieter, cleaner build with far less wet-trade work than pouring concrete; (6) strong fire performance, since thick panels char predictably on the surface and protect the load-bearing core; (7) solid acoustic and thermal insulation built into the panel itself; (8) better seismic resilience, because a lighter building faces lower forces during an earthquake; (9) safer sites, as lighter components need less heavy machinery to lift and place; (10) lower embodied energy across the whole supply chain than steel or concrete equivalents; (11) efficient logistics, since flat panels stack and ship easily by truck or container; and (12) more predictable costs and schedules, because factory production avoids the weather delays common to site-poured materials.
In Java, Indonesia, not far from the Port of Surabaya, we press our CLT panels. The panels then move into processing, customization, prefab preparation, quality control and finishing with our trusted partner, Fill (PT Timber Solution Indonesia).
No more than for any other heavy-timber or concrete building — in fact CLT behaves well in a fire because of how it burns. A thick CLT panel chars on the exposed face at a slow, predictable rate, and that char layer insulates the unburned wood beneath it, so the panel keeps its load-bearing strength for a long time even while the surface is on fire. This is the same char-rate principle engineers use to calculate fire-resistance ratings for heavy timber generally, and it's why CLT panels of typical structural thickness meet the fire-resistance ratings building codes require for houses, villas and hotels. Full-scale burn tests on real CLT structures back this up. As with any material, safe detailing still matters — protected connections, sealed service penetrations and code-compliant fire separations — and our team accounts for all of that in every project.
If you're interested in joining the CLT — and MET/Glulam — journey in Indonesia, we're open to discussing opportunities. That could mean actively working together, investing, joining us for an internship, or simply helping promote the technology. Get in touch, introduce yourself and let's see where we can create mutual value.
Houses, villas and hotels — and more broadly any project where sustainability, fast erection, beauty, a healthier indoor environment, dimensional precision and low-carbon construction matter. CLT can also be well suited to government projects, remote or hard-to-reach locations, temporary buildings and additions to existing buildings.
INCLT targets around three months to produce a project's panels once the down payment (DP) is received, though the exact timeline still depends on the project's scope and complexity. Assembly and erection time on site is separate from production and varies with the project's size and location, so we estimate it individually for each project. As a general rule, CLT erection tends to be considerably faster than traditional construction, since the major structural elements are prefabricated off-site and arrive ready to install, while traditional construction typically involves more on-site work and sequencing. That said, we don't quote a fixed erection duration up front — get in touch with your project details and we'll work out a realistic estimate together.
A properly designed and constructed CLT house requires relatively little maintenance. The most important principle is simple: keep the structural CLT dry and protected. Good design is the first line of protection in Indonesia's tropical climate. Roof overhangs, proper drainage, ventilation, waterproofing and correctly detailed windows, doors and connections help protect the structure from heavy rain, humidity and direct sunlight. Interior CLT walls and ceilings generally require very little maintenance. Exterior timber exposed directly to sun and rain requires more attention and may need periodic recoating. Where possible, we protect structural CLT with suitable cladding and façade systems. We recommend a simple annual inspection of the roof, gutters and drainage, façade, windows and doors, seals and waterproofing, termite protection and any areas where water could potentially enter the building. With good design, correct construction and regular basic maintenance, a CLT building is designed for a long service life. Timber structures can perform for generations when they are kept dry and properly protected. The Build in CLT approach is prevention through design and construction: maintenance starts with good design. We consider Indonesia's climate, rainfall, humidity and termites from the beginning—creating CLT buildings that are not only beautiful and sustainable, but also practical and durable.
Termites are a natural part of Indonesia's tropical environment and should be taken seriously when building with timber. However, the most important strategy is not simply treating the wood—it is designing the building to avoid termite access in the first place. Termite protection starts at the foundation. The timber structure should be separated from the soil, protected from hidden entry points and detailed so that critical areas can be inspected. Physical barriers, appropriate foundation details and controlled penetrations for pipes and cables can all form part of the protection strategy. Depending on the location and project, additional protection such as soil treatment, physical termite barriers or suitable timber treatments may be recommended. The right solution is determined during the design and construction process. Keeping the building dry is an important part of protecting any timber structure. Good drainage, ventilation, waterproofing and avoiding water accumulation around the foundation help create conditions that are less favorable for termite activity and other biological deterioration. Prevention works best when combined with periodic inspection. Because the building is designed with accessible and inspectable critical areas, signs of termite activity can be identified early and addressed before structural damage occurs. The Build in CLT approach is simple: avoid access, keep the structure dry, make critical areas inspectable, and add appropriate barriers or treatments where required. Good CLT construction is not about fighting termites later—it is about designing them out from the beginning.
Our pricing is based on several project-specific factors, so we cannot simply provide one price per m². However, we can give you a fast indicative price once we understand the following. The design: What does the building look like? How large is it in m², what is its purpose, and is it temporary or permanent? If you already have a design, we are happy to convert and optimize it for what is possible with CLT. If you do not yet have a design, we can connect you with trusted architects who understand CLT. The roof design is also important. The location: Location strongly influences pricing because we need to understand the site, soil conditions and foundation planning. We can also organize transport and assembly. You can ask us to carry out the required site and soil research, or provide us with the necessary information. The extras: Windows and doors, stairs, lighting, kitchen and bathroom, terrace and/or balcony all influence the final scope and price. These details need to be discussed so we can provide a useful indicative price. Once the indicative price is accepted, we can work out the project in more detail and prepare the timeframe, specifications and final pricing.
INCLT (PT Prima Makmur Teknik) is the producer of Cross-Laminated Timber and your specialist for applying CLT to a project. But to fully benefit from CLT, we need to think beyond individual panels—we need to think prefab. A complete prefab building requires more than CLT alone. That is why INCLT works closely with Fill (PT Timber Solution Indonesia) as our trusted partner for project preparation, completion, assembly and delivery. Our teams work together as one experienced project team. You can place your CLT order directly with INCLT, and we coordinate the necessary details with Fill and the other specialists involved. The result? One coordinated process, less complexity for you, and all the benefits of CLT: fast, accurate and professional project delivery. Let us know if you want to meet Fill.
The connection method is an important part of every CLT project because it influences structural strength, erection speed, appearance, fire performance and price. Wooden joints can create beautiful results and keep the expression of the building very timber-focused, although installation can be somewhat slower and not every project can be engineered using only wooden joints. Hardware connections are commonly used, and we work with a broad network of hardware producers, allowing us to select suitable local brands or imported products for each project. An important design decision is whether the hardware should be exposed or hidden. Hidden hardware can provide better fire protection and a cleaner, more timber-focused appearance. Exposed hardware can allow faster erection and gives the building a more industrial look, but exposed metal is more directly affected by fire and therefore requires appropriate fire-safety design. For every project, we select and engineer the connectors based on structural safety, visibility, budget, fire requirements and speed of construction.
