An old house typically refers to a property that is 15–20 years or older, often featuring:
Outdated electrical wiring
Aging plumbing systems
Worn structural components
Inefficient space layouts
Such houses usually require more than cosmetic upgrades.
Renovating an old house can be more practical than rebuilding when:
The structure is still sound
The location is desirable
Rebuilding approval is complex or restricted
Budget constraints exist
Renovation allows homeowners to modernize while preserving existing foundations.
Cracks in walls or beams
Uneven floors
Roof leakage or termite damage
A structural assessment is recommended before design planning.
Old houses often use outdated wiring and piping that:
Do not meet current safety standards
Cannot support modern appliances
Upgrading these systems is usually necessary.
Poor waterproofing can lead to:
Damp walls
Mold growth
Long-term structural damage
This is a critical but often overlooked area.
Professionals inspect the structure, utilities, and existing layout to determine what can be retained or must be replaced.
Designers:
Reorganize layouts for better flow
Improve lighting and ventilation
Integrate modern living requirements
Design planning should always come before renovation work.
Depending on scope, permits may be required from:
Local councils (e.g., DBKL)
Property management (for strata properties)
Structural changes almost always require approval.
This stage may include:
Hacking walls and floors
Reinforcing structures
Replacing electrical and plumbing systems
Older homes usually require more extensive preparation work.
Includes:
Flooring and wall finishes
Carpentry and cabinetry
Painting and lighting installation
Final inspections ensure safety, compliance, and workmanship quality before occupancy.
Issues such as hidden water damage or termite infestation often appear after demolition.
Old house renovations may cost more due to:
Structural reinforcement
Full system replacements
Unforeseen repairs
A contingency budget is strongly recommended.
Older houses may not meet current building codes and require upgrades to comply.
Renovation costs vary based on condition and scope:
| Renovation Scope | Estimated Cost |
|---|---|
| Basic upgrade | RM100 – RM150+ per sq ft |
| Partial overhaul | RM150 – RM200+ per sq ft |
| Full renovation | RM200 – RM300+ per sq ft |
Actual costs depend on materials, workmanship, and site condition.
Conduct a professional site inspection first
Prioritize safety over aesthetics
Allocate 10–20% contingency budget
Work with experienced renovation specialists
Finalize design before construction
Rebuilding may be more suitable if:
Structural damage is severe
Renovation costs exceed rebuilding costs
Layout limitations cannot be resolved through renovation
A professional assessment helps determine the best option.
