How much does it cost to rebuild a landed house in Singapore?

This is probably the question I hear the most. My honest answer? It’s becoming increasingly difficult.

Can it still be done? Perhaps. If the design is straightforward, the specifications remain practical and the scope is carefully managed, it may still be possible.

But if you’re asking me what I would realistically prepare today for a proper three-storey inter-terrace rebuild, I’d say budget from at least S$1.65 million onwards.

From there, the cost depends on the kind of home you want to build. The moment you start adding a lift, an attic, larger aluminium systems, premium finishes, feature walls, smart home systems or higher-end carpentry, the budget naturally increases.

There is absolutely nothing wrong with wanting those features. The important thing is understanding what they cost before the design is completed, not after.

I’ve seen homeowners spend months perfecting a design, only to realise later that it exceeds their budget by several hundred thousand dollars. That’s a conversation I’d rather have on Day One than six months later.

Another misconception I hear quite often is this: “Keith, construction takes about two years, right?”

Not exactly. The day construction starts isn’t the day your project begins.

Long before the first excavator arrives on site, there’s already a huge amount of work happening behind the scenes. The layout has to be planned, the design has to be refined, the budget has to be aligned, and the structural engineer, architect and consultants need to coordinate.

Then come the authority submissions, including:

• URA
• BCA
• SCDF
• PUB
• SP Group
• NetLink Trust

When a homeowner tells me, “My budget is S$2.5 million,” I usually ask another question: “Does that include everything?”

Construction is only one part of the overall investment. There are many other costs that homeowners often forget to budget for.

Things like soil investigation, topographical survey, authority fees, temporary accommodation while the house is being rebuilt, loose furniture, curtains, kitchen appliances, landscaping, swimming pools, solar panels, home automation and even lift maintenance after the project is completed.

These items may not all form part of your builder’s contract. But they are still part of the overall cost of building your home.

Having a realistic overall budget from the beginning makes decision-making much easier throughout the project.

This is probably one of the questions homeowners ask me the most. And honestly, there isn’t one answer that suits everyone.

Traditional tender has its strengths. If you already have a completed design and simply want builders to quote exactly what has been drawn, it can work very well.

Design & Build works differently. The builder, designer and consultants work together much earlier in the process. Personally, I think this approach is particularly valuable when budget certainty is important, because every design decision can immediately be discussed against its construction implications.

Sometimes a very small design adjustment can save tens of thousands of dollars, and the homeowner would never even notice the difference after moving in. Maybe the structural beam is shifted slightly. Maybe the staircase is designed differently. Maybe there’s another way to support that opening without making the structure so expensive.

The finished house still looks almost the same. But the cost to build it can be very different.

This becomes even more important for projects involving basements. Basements rarely go through just one submission. There are often multiple rounds of discussions between the architect, professional engineer and the authorities.

A seemingly small structural change can affect excavation, waterproofing, retaining walls and ultimately, the construction cost.

When the builder only comes in after everything has already been designed, there is naturally less opportunity to influence those decisions because the builder’s job is simply to price what has already been drawn.

It doesn’t mean the design is wrong. It simply means many of the major cost decisions have already been made.

This is one of the reasons we built Inspired Homes as a Design & Build company. Not because we believe it’s the only way, but because we wanted the designer, builder and engineers discussing construction methodology, structural implications and budget from Day One.

Our objective isn’t simply to design a beautiful house. It’s to design one that’s beautiful, buildable and financially realistic.

From time to time, homeowners ask me, “Keith, why don’t you provide free drawings like some companies?”

My answer is always the same. A floor plan by itself tells you almost nothing about what your house is actually going to cost.

Without understanding the structural implications, authority requirements, buildability and construction methodology, a beautiful drawing can easily create expectations that don’t match reality.

I’ve met homeowners who came to us after spending months refining beautiful plans. The problem wasn’t the design. The problem was that nobody had told them the house would cost another S$300,000 or S$500,000 beyond what they were prepared to spend.

By then, they’re emotionally attached to the design. Rooms become smaller. Features get removed. The house has to be redesigned. Months of work are lost.

I’d much rather have an honest conversation at the beginning than an uncomfortable one six months later.

That’s why we don’t believe the real value is in giving away free drawings. We believe the real value is giving homeowners clarity.

Because once you know what can realistically be built within your budget, every decision after that becomes much easier.

Many homeowners spend weeks comparing quotations. Very few spend the same amount of time comparing the people behind those quotations.

Price matters. Experience matters. But after rebuilding landed homes for more than a decade, I believe one thing matters just as much: accountability.

When problems arise—and they will, because construction is never completely perfect—you want to know who’s taking responsibility for solving them.

The cheapest quotation will never compensate for poor communication, delayed decisions or different parties blaming one another. A home worth millions deserves better than that.
