Building in Indonesia can be an incredible opportunity. The landscapes are world-class, labour costs can be attractive, and demand for quality villas and apartments continues to grow across hotspots like Lombok and Bali.
But it's also a market where things can go wrong quickly if you don't understand how projects are actually delivered on the ground.
At Goss Group, we've seen firsthand why some developments struggle, and why others succeed. Below are the most common mistakes investors and developers make when building in Indonesia, and how to avoid them.
1. Rushing contractors (speed over structure)
One of the biggest traps is pushing contractors too hard, too fast. In Indonesia, construction is still highly relationship-driven and process-based. When timelines are forced without proper planning, the result is often:
- Corners being cut
- Poor sequencing of works
- Structural shortcuts that aren't obvious until years later
The fix:
- Lock in realistic timelines
- Use staged milestones with quality checks
- Work with builders who are properly resourced, not just available
Fast builds look good on paper, but controlled builds last.
2. Underestimating the real budget
Many first-time builders budget for construction only, forgetting the true cost stack in Indonesia. Commonly missed or underestimated costs include:
- Site preparation and earthworks
- Access roads and retaining walls
- Drainage and water management
- Power, water, and internet connections
- Design changes mid-build
- Local compliance and permit delays
The fix:
- Build in contingency (often 10 to 20%)
- Budget for infrastructure, not just the villa or building
- Work with a team that understands local pricing fluctuations
If the budget is too tight, quality usually pays the price.
3. Ignoring access and drainage (a costly mistake)
This is one of the most common, and expensive, oversights. Making this mistake doesn't just turn your build into a nightmare. It can have long term ramifications for your ongoing profitability, or your buyers. Indonesia's wet season is no joke. Sites that look perfect in dry season can turn into:
- Flood zones
- Mud traps
- Unusable access points
Poor access also affects:
- Construction logistics
- Emergency access
- Long-term rental and resale appeal
The fix:
- Assess access and drainage before buying land
- Engineer water flow, not just buildings
- Invest early in proper roads and storm water systems
Water will always win, unless you plan for it.
4. Designing without the climate in mind
Many projects fail because they copy overseas designs that simply don't suit the tropics. Common issues include:
- Poor ventilation
- Overheating interiors
- Mould and moisture problems
- High ongoing maintenance costs
The fix:
- Design for airflow, shade, and cross-ventilation
- Use materials suited to heat, humidity, and salt air
- Think about how the building lives, not just how it looks
Good tropical design reduces operating costs and improves guest experience.
5. Poor build quality due to skill misalignment
Not all builders are created equal. A contractor who builds basic homes may struggle with:
- Architectural villas
- Structural detailing
- Waterproofing
- Finishes expected by international buyers
This often results in:
- Uneven finishes
- Cracking and leaks
- Shorter building lifespan
The fix:
- Match builder experience to project complexity
- Inspect previous work in person
- Use independent quality control, not blind trust
The cheapest builder is rarely the most cost-effective.
6. Dodgy contractors and weak contracts
Unfortunately, especially in Lombok, the industry still has its share of:
- Unlicensed builders
- Cash-only operators
- Contracts with no enforceable protections
Red flags include:
- No clear scope of works
- Vague timelines
- Large upfront payments
- Resistance to reporting or transparency
The fix:
- Use properly structured contracts
- Stage payments against verified progress
- Work with developers and project managers who are locally established
Due diligence isn't optional, it's essential.
7. Lack of on-ground oversight
Remote builds without strong local management are high-risk. Without daily or weekly oversight, issues can compound quickly:
- Materials swapped without approval
- Design deviations
- Quality slipping unnoticed
The fix:
- Have trusted on-ground project management
- Manage the build yourself, on the ground
- Document progress consistently
- Treat visibility as non-negotiable
If you can't see it, you can't control it.
Final thoughts: build smart, not just cheap
Indonesia offers enormous opportunity, but success comes from local knowledge, realistic planning, and disciplined execution. At Goss Group, we focus on developments that are:
- Designed for the tropical climate
- Built by the right teams, not the fastest ones
- Supported by proper infrastructure and long-term thinking
When you build smart from day one, you don't just protect your investment, you enhance it.
