Complete Resale Renovation Singapore Guide: Packages, Cost & Process

Buying a resale flat gives you more space, better locations, and faster move-in timelines — but it also comes with renovation considerations that new BTO flats don’t face. Understanding resale renovation in Singapore is essential if you want to avoid hidden costs, delays, or poor workmanship.
 

This guide walks you through resale renovation packages, realistic cost ranges, and the step-by-step renovation process, so you know exactly what to expect before you begin.
 

What Is Included in a Resale Renovation?
 

Unlike BTO flats, resale units usually require more extensive work due to ageing finishes, outdated layouts, and old plumbing or wiring.
 

A full resale renovation Singapore project commonly includes:

• Hacking and removal of existing flooring, tiles, and carpentry
• Electrical rewiring and additional power points
• Plumbing works and pipe replacement
• Kitchen renovation and carpentry
• Toilet renovation with mandatory waterproofing
• Painting, tiling, and finishing works
• Interior design planning and project coordination

The actual scope depends on the condition of the flat and how much you plan to change.
 

Resale Renovation Packages in Singapore

Many homeowners choose renovation packages to manage costs and scope more clearly. Here are the most common options.
 

1. Partial Resale Renovation Package
 

Best for flats in relatively good condition.
 

Typically focuses on:

• Kitchen renovation
• Toilet upgrades
• Selective carpentry and painting

This option keeps costs lower while refreshing key living areas.
 

2. Full Resale Renovation Package
 

Ideal for older flats or homeowners planning long-term stays.
 

Common inclusions:

• Full hacking and retiling
• Electrical and plumbing overhaul
• Kitchen and bathroom renovation
• Built-in carpentry for storage
• Design planning and supervision

This is the most popular choice for resale homeowners who want a full transformation.
 

How Much Does Resale Renovation Cost in Singapore?

While costs vary by flat size and scope, here are realistic budget ranges most homeowners should plan for:

• 3-room resale flat: $28,000 – $40,000

• 4-room resale flat: $35,000 – $55,000

• 5-room resale flat: $45,000 – $70,000+

Factors That Affect Cost

• Amount of hacking required
• Condition of plumbing and electrical systems
• Carpentry volume and materials
• Tile and sanitary fitting choices
• Custom design elements

Resale renovation costs are higher mainly because of restoration work, not just design.
 

Step-by-Step Resale Renovation Process

Knowing the renovation process helps you plan timelines and manage expectations.
 

1. Site Inspection & Design Planning

Assessment of the flat’s condition, layout planning, and budget discussion.

3. Hacking & Structural Preparation

Removal of old finishes, fixtures, and built-ins.
 

4. Electrical & Plumbing Works

5. Waterproofing & Tiling

6. Carpentry, Painting & Installation

7. Inspection & Handover

A typical resale renovation Singapore timeline ranges from 6 to 10 weeks, depending on complexity.
 

Key HDB Renovation Rules for Resale Flats
