Design and build, end to end
One contract from concept to completion. You brief one team, one budget and one programme, and there is no gap between the person who drew it and the person pouring the concrete.
Design & build
Villa contractor in Bali,
and the architect too
Neptune Property is a construction company that also designs. If you have land and an idea, we can take it from the first sketch to the handover of the keys — drawings, permits, structure, finishes, landscaping — under one contract, with our own site teams rather than a chain of subcontractors.
What we take on
Build to your architect's drawings
Already have a design you love? We build to it, and we say so early if something on the page will not survive Bali’s rain, salt or soil.
Renovation and extension
Older villas, tired finishes, failed waterproofing, a pool that needs rebuilding rather than patching.
Commercial work
Hotels, restaurants and residences — we have delivered all three, in Bali and across Java.
Why owners hire us
Fourteen years on this island
Long enough to know which subsoils move, which suppliers deliver, and how long a permit actually takes.
Our own trades, on our own payroll
More than a hundred people across architecture, engineering, project management and the trades. Quality is not something we subcontract and hope for.
Structural guarantee up to ten years
Covering structure and waterproofing. We are the contractor, so the guarantee is ours to honour.
Payments tied to progress
Staged against construction milestones agreed before work starts — not against a calendar.

- Building Permits in Bali: PBG, SLF and What They Mean for Your BuildIMB is gone. What PBG and SLF actually are, how zoning decides what you may build on a Bali plot, and where the permit really sits in a project timeline.
