Where Your Renovation Budget Actually Goes (and the Few Places Worth Saving)

Carpentry, hacking, wiring, waterproofing. Where renovation money really goes in a Singapore home, where to save and where cutting costs backfires.

The Assembly Design

Most people set a renovation budget by asking friends what they paid. That's a reasonable starting point and a terrible finishing point, because your friend's flat, scope and taste aren't yours.

A better way to think about it: split the money into what you'll see every day, and what you'll never see again once the walls close up.

The money you'll see

Carpentry is usually the biggest single line in a Singapore renovation quote. Wardrobes, kitchen cabinets, TV consoles, shoe cabinets, platforms. It's also where quotes are hardest to compare, because "kitchen cabinet" can mean very different boards, laminates and hardware.

Then come flooring, feature walls, false ceilings, lighting and painting. These are the things you'll photograph, and the easiest places to overspend without noticing.

The money you won't see

Hacking and masonry, waterproofing, electrical rewiring, plumbing and screed. None of it looks exciting on a quote. All of it is expensive to redo, because redoing it means tearing out the nice things on top.

Where saving makes sense

  • Loose furniture instead of built-in. Not everything needs to be carpentry. A good sideboard or bookshelf can move house with you. A built-in one can't.
  • Overlay instead of hacking, where your floor or wall tiles are sound. Less noise, less debris, less cost.
  • One feature wall, not four. A home with a feature everywhere has no feature anywhere.
  • Standard cabinet sizes and simple carcasses, with the budget spent on the doors and handles you actually touch.

Where saving backfires

  • Waterproofing. A leak into the unit below costs far more than doing it properly the first time.
  • Electrical. Enough power points in the right places. Adding one after the carpentry is built is messy and costly.
  • Hinges and drawer runners. Cheap hardware is the first thing to fail in a kitchen, and you'll notice it every single day.
  • Anything inside a wall or under a floor. If it's hard to reach later, do it right now.

How to compare two quotes fairly

Two quotes with different totals are often quoting different things. Before you compare prices, line up the specs:

  • Carpentry measured the same way (usually per foot run), with board type, laminate and hardware brands stated.
  • The same number of power points, lights and plumbing points.
  • What's excluded. Haulage, cleaning, dismantling old carpentry and permit fees can sit outside one quote and inside another.

A quote that's cheaper because it leaves things out isn't cheaper. It's just later.

Keep a buffer

Set aside a contingency on top of the quote, more for older resale flats where you can't see what's behind the tiles. If you don't need it, great. If you do, you'll be glad it's there and not on your credit card.
