Terrace-house renovation cost in Singapore depends on what is being retained, repaired and replaced. An interior refresh, a full services-and-finishes overhaul, and a structural alteration are different scopes. Before comparing totals, establish which one describes your house.
This guide explains how to build and compare a terrace renovation budget. A site assessment and measured scope are needed for a reliable quotation; a broad online range cannot establish the cost of your particular home.
Separate Three Renovation Scopes
Selected Interior Refresh
This may retain the layout and most existing services while changing selected finishes, lighting or cabinetry. Confirm the condition of retained items and whether new work depends on hidden repairs. Retaining a component is useful only when it remains suitable for the intended use.
Comprehensive Interior Renovation
This can involve several bathrooms, kitchens, flooring, substantial carpentry and renewal of services. Ask the proposal to identify the rooms included and the extent of electrical, plumbing and air-conditioning work. The phrase ‘whole-house renovation’ is not a specification.
Structural Alteration, Extension or Reconstruction
These scopes require separate feasibility and professional assessment. Do not compare their budgets directly with an interior-only package. Confirm the applicable design, approval and construction responsibilities for the actual proposal with the relevant professionals.
Why Terrace Houses Need a Site-Specific Budget
A deep plan, limited side access and work across several levels affect how materials and debris move through the house. Ask how protection, access, staging and waste removal will be managed. A corner terrace may offer different access but may also involve more external surfaces or outdoor work.
Check roof leaks, waterproofing, plumbing, electrical installations and other existing conditions before fixing decorative work. A new interior designed around failing services can be expensive to reopen later. Our terrace-house design guide discusses the layout considerations.
Request an Itemised Cost Schedule
- Removal and site preparation: protection, dismantling, access and disposal.
- Repairs and wet works: the assessed scope, areas and specified materials.
- Services: electrical, plumbing, cooling, data and related installation work.
- Finishes and carpentry: measured quantities, finishes, hardware and installation.
- Coordination and specialist work: identified services, responsibilities and exclusions.
Separate confirmed prices from allowances that depend on selections or investigation. Ask whether taxes, delivery, professional services and third-party charges are included where applicable.
Check the schedule against the main landed renovation cost drivers so retained services, access and specification are addressed explicitly.
Compare Quotations on the Same Basis
Give each tenderer the same plans, requested scope and material expectations. A lower quotation may leave more items provisional, retain more existing work or exclude components included elsewhere. Clarify those differences before comparing headline totals.
For example, suppose two hypothetical proposals show S$220,000 and S$250,000. The lower number is not automatically better value if it excludes bathroom renewal or substantial electrical work that the second includes. These figures illustrate comparison only; they are not market rates or a Yang’s quotation.
Keep a Separate Allowance for Unresolved Work
Ask the design and project team which existing conditions are still uncertain and how they will be investigated. Relate the allowance to those risks rather than treating one percentage as right for every house. Keep optional upgrades separate from money reserved for necessary unforeseen work.
Before approving a change, obtain its scope, price and programme effect in writing. Keep a running record of the accepted quotation and approved changes so the expected total remains visible throughout the project.
Prepare for a Useful Site Discussion
Bring available plans, the intended scope, known defects, retained furniture and your target move-in date. Explain whether you need to remain in the house during any works. Access, sequencing and temporary arrangements should be considered before a programme is promised.

Frequently Asked Questions
Can I Renovate a Terrace House on a Fixed Budget?
A defined budget helps prioritise scope, but the proposed work must be tested against the condition of the house. Identify essential repairs first and agree which optional works can be deferred.
Is a Corner Terrace Always More Expensive?
No. Scope, area, condition, access and specification matter. Extra exposed surfaces may add work, while different access can change logistics.
Should I Renovate or Rebuild?
Compare feasible options after assessing the building and your requirements. A construction professional’s assessment is needed where structure, extensions or substantial replacement are being considered.
