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

This guide walks you through whole house 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 Whole House Renovation?

A whole house 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.
