Project budget Lombok building guide
There is no single price per square metre for a villa in Lombok. Here is how to build a budget you can defend, with published reference points.
"How much per square metre?" is usually the first question buyers ask about building in Lombok, and it is the hardest one to answer honestly. Two villas with the same floor area can differ in cost several times over, depending on the design, the finishes, the slope of the land and how far the site is from roads, power and water. This guide sets out the reference prices that are publicly available, the cost lines that sit outside the headline rate, and a method for building a budget before you commit to a plot.
Published reference points
Very few sources publish construction costs for private villas with their workings shown. Two public reference points are useful as bookends:
- Government building rates: West Lombok Regent Regulation No. 10 of 2024 sets a standard highest unit price of Rp5,910,000 per square metre for building structures procured by the regional government in 2024. It applies to government buildings, not villas, but it shows the price level for conventional construction in the region.
- Luxury private villas: Emerhub, a business services firm, puts a typical luxury villa standard in Lombok at Rp12 million to Rp15 million per square metre in an article last updated in October 2025.
Other publishers have stopped quoting averages because the range is too wide to be useful without project details. Treat any single figure, including the two above, as a starting point for a conversation with a contractor, not a budget.
What the headline rate usually covers
When a contractor quotes a rate per square metre, it usually covers the enclosed building: foundations, structure, walls, roof, doors and windows, basic electrical and plumbing, and the finishes listed in the specification. Many items sit outside it. Ask the contractor to state clearly what is included.
| Cost line | Often outside the headline rate? | What to ask |
|---|---|---|
| Site clearing, levelling and retaining walls | Yes | Has the quote been based on a survey of the actual slope? |
| Swimming pool and pool equipment | Yes | Size, finish, filtration and pump room included? |
| Decks, terraces and covered outdoor areas | Often | Are they priced per square metre or as separate items? |
| Kitchen, wardrobes and built-in joinery | Often | Which items are in the specification? |
| Furniture, appliances and soft furnishings | Yes | Who supplies and installs them? |
| Landscaping, fencing and gates | Yes | Is there an allowance, and how was it set? |
| Power connection, water source and wastewater | Yes | Who arranges connections and treatment systems? |
| Access road and drainage | Yes | What width and surface are assumed? |
| Design, engineering and permits | Yes | Who prepares certified drawings and the PBG application? |
Factors that push costs up in Lombok
- Slope: hillside plots with sea views are popular, but every metre of level change can mean retaining walls, deeper foundations and more drainage work.
- Distance: materials, specialist trades and equipment often come from Mataram or further. Remote sites pay for transport time and sometimes for worker accommodation.
- Seismic design: Lombok experienced damaging earthquakes in 2018. A structural engineer should design the frame and foundations to Indonesian seismic standards, and that is money well spent.
- Coastal exposure: salt air corrodes standard fittings. Stainless or marine-grade hardware, better coatings and more maintenance add to both build and running costs.
- Weather: the rainy season, roughly October to April, slows earthworks and concrete. Emerhub puts typical villa build times at 12 to 20 months, and wet-season delays are a common reason for overruns.
Building a budget step by step
- Define the brief. Number of bedrooms, enclosed floor area, outdoor areas and pool size. Decide whether the villa is a private home or a rental, because rental use brings extra licensing and operating requirements.
- Price the site first. Before the building, estimate access, levelling, retaining, utilities and drainage for the specific plot. Our guide to utilities and road access costs lists what to investigate.
- Set a quality level. Use the reference points above to choose a realistic range per square metre for your specification.
- Add soft costs. Architecture, structural and MEP engineering, surveys, soil testing, permits and project management.
- Add fit-out. Furniture, appliances, linen and equipment, especially for a rental villa.
- Add contingency. Many project managers hold back 10% to 20% depending on how much is still unknown. A site you have not surveyed needs the higher end.
- Test it with quotes. Ask at least two contractors for an itemised cost plan (RAB) based on the same drawings and specification.
A worked example
Take a 200 square metre villa built to a high standard at Rp12 million per square metre. The enclosed building comes to Rp2.4 billion. Add a pool, terraces, landscaping, utilities, design fees, permits and furniture, and the total can rise well above that figure before contingency. The point of the exercise is not the final number. It shows how much of the budget sits outside the headline rate, and which lines you need site-specific prices for.
Plan for running costs too
The build budget is a one-off. A villa in Lombok also has yearly costs that should shape the design from the start:
- Maintenance: repainting, roof checks, pool servicing and replacing fittings damaged by sun and salt. Simple, durable materials cost less to keep looking good.
- Staff: a gardener, pool cleaner or caretaker, and housekeeping if you rent the villa out.
- Utilities: electricity for air conditioning and pumps, water treatment and internet. Good shading and cross-ventilation reduce power bills for years.
- Taxes and compliance: the annual land and building tax, insurance, and periodic renewal of the building's certificate of fitness for use.
Asking a contractor to price a cheaper finish is easy. Paying for that choice every year is the part buyers tend to miss.
Contracts and payments
Agree payments by construction milestones rather than by date, with an itemised list of labour, materials and allowances. Keep a retention amount until defects are fixed after handover. Withholding tax on construction services depends on the contractor's business status, so ask your tax adviser how to handle it. Build only once you have the PBG, and plan for the SLF before the villa is used. Our guide to PBG and SLF explains the approvals.
Buyer note: Construction prices move with materials, labour and exchange rates. Ask for quotes dated close to your start date, and update the budget if the design changes.

Property examples to compare
Site work varies a lot between flat and hillside plots. Compare 6 Ha Beachfront Land in Nambung, 6 Ha Bay View Land in Batu Berang and 4.37 Ha Commercial Land near Mandalika Circuit. Ask our team for contour and access details before you price a design.
