Major Home Renovation
For homeowners planning a major change: a full renovation, an added storey or a change of use. Renovation starts with a review of the existing building, because that is where most cost and time risks sit.
When you need this service
- 01
The house needs a complete rethink: layout, facade and building services.
- 02
You plan to add a storey and need to confirm the existing structure can carry it.
- 03
There are recurring issues such as leaks, cracks or ageing electrical wiring.
- 04
You need to know whether the work can be phased or done while you live there.
Scope
Existing-condition review, transformation design, risk identification and full renovation works.
Included
- Survey and documentation of existing conditions
- Initial structural and MEP review of the existing building as needed
- Architectural and interior transformation design
- Risk identification, bill of quantities and contingency
- Work phasing plan, including when the house stays occupied
- Construction, supervision, progress reporting and handover
What you receive
- Survey report and photos of existing conditions
- Design and renovation working drawings
- Bill of quantities with assumptions and scope limits
- Schedule and sequence of works
- Progress reports, change log and punch list
- Signed handover certificate
Scoped separately
- Hidden conditions found after demolition are handled as a variation order before any work proceeds.
- Permitting is defined as a separate scope when required.
- Moving belongings and temporary housing are outside the scope unless agreed.

Budget and timing
What shapes the cost
Renovation costs depend heavily on the existing building: structure, roof, electrical and plumbing systems, and moisture. That is why the existing-condition review comes before the final estimate, and contingency is shown openly in the bill of quantities. The sequence and duration of works are planned around how the house is occupied.
Indicative price per m²
- BasicFrom Mulai dari Rp 4.200.000/m²
- PremiumFrom Mulai dari Rp 5.500.000/m²
- LuxuryFrom Mulai dari Rp 8.000.000/m²
These prices are indicative, to help you gauge the scale of your budget. They are not a final offer: final costs are set in a bill of quantities after the survey, design and scope definition.
Safeguards

Can we stay in the house during the renovation?
Often yes, with agreed work zones and sequencing. Feasibility is confirmed after the survey, as it depends on the scope and the condition of the house.
What if something is found after demolition?
Findings are recorded and discussed with you. Cost and time impacts are submitted as a variation and approved before any work proceeds.
Can an extra storey be added to an older house?
It can be considered once the existing structure has been assessed. We do not recommend adding a storey without a structural review first.
