A&A Works, Reconstruction & Rebuilds in Sembawang

Landed roads in the far north, generally lower density than the central estates, with a mix of older housing and more recent rebuilds on regular plots. Plots here are often more generous than their equivalents further south, which widens what is possible once the envelope is confirmed.

What we see here

The Work That Comes Up in Sembawang

Full rebuilds where plots allow a substantially larger house, and structural work on older northern housing stock.

What none of that tells you is what your plot allows. That is set property by property, and it is the first thing we establish — before any drawing, and before any number.

Before we quote

What We Check on a Sembawang Property

  1. Your plot's URA record. Zoning, the building envelope, setbacks from each boundary, and any control specific to your property — including Good Class Bungalow or conservation status where it applies. Sometimes this alone tells us an idea will not be approved.
  2. The existing structure. For anything built before about 1990, a foundation review and load calculation. An older house was not designed for an added storey and today's finishes.
  3. Neighbouring conditions. Party walls, how close the houses either side sit, and whether shoring or underpinning will be needed. This decides feasibility more often than the design does.
  4. Site access. Whether machinery can physically reach the plot, and what has to be done differently if it cannot. On tighter roads this drives both method and cost.
  5. What it means for you. A real number with line items, after the site visit and architect input — not a same-day guess with a decimal point on it.
What you get

The Same Terms Everywhere We Work

  • BCA General Builder Class 2 (GB2), bizSAFE Level 3.
  • Seven-year workmanship warranty on a landed home, covering everything we build, and it follows the house if you sell. Painting is five years — Nippon's own limit on the product.
  • 5–10% deposit, the rest billed against completed milestones. Stop at any point and pay only for what is done.
  • Public liability insurance for the whole project.
  • The builder on site. Larry Hoo is the Director and does the work; an Architect and QP handle design and certification.

Common questions

Sembawang — Answered

Do you carry out A&A works in Sembawang?
Yes. Wong Lye works in every district in Singapore except Sentosa, with our own team and subcontractors we have used for years. Sembawang is within that coverage, and being further from our base does not change the quotation — the cost is driven by the condition of the existing house, how much you are adding, site access and finishing standard.
What can I actually build on my plot in Sembawang?
That is decided plot by plot, not estate by estate. URA sets the building envelope, setbacks from each boundary, and the number of storeys for your specific property, and some plots sit inside Good Class Bungalow or conservation boundaries with tighter rules again. Two houses on the same road can differ. We pull your property's actual URA records before quoting rather than assuming what a neighbour did is permitted — sometimes that tells us straight away an idea will not be approved, which is better learned before you pay anyone to draw it.
My neighbour did a similar extension. Can I do the same?
Not necessarily, and it is the most expensive assumption in landed renovation. Their plot may have a different envelope, their approval may pre-date a rules change, or the work may simply never have been approved. We check yours specifically.
Can the existing house take another storey?
For anything built before about 1990 we do a foundation review and a column and beam load calculation before quoting. Older landed houses were not designed for today's loads — an added storey, heavier finishes, solar panels. Sometimes the answer is reinforcement first; occasionally the honest answer is that rebuilding costs less than propping up what is there. The check costs you nothing; it is part of how we quote.
Who handles the URA and BCA submissions?
We do, as part of the build. An Architect and a Qualified Person handle the design and the certification that has to be signed. Larry Hoo, the Director, is the builder and is on site — he is not the engineer, and does not pretend to be.
What warranty do I get on a Sembawang project?
On a landed home, seven years from handover on everything we build — structural, plumbing, masonry, partitions and windows — and it follows the house, so if you sell, the buyer inherits the balance. Painting is quoted at five years because that is Nippon's own warranty on the product and we will not promise longer than the maker will. There is no inspection fee during the period: send a photo or video, or we send someone, and a small issue is settled at no charge.
How long does an A&A or rebuild take?
A focused A&A typically runs 6 to 12 months; a full reconstruction 12 to 18. Submissions alone can take 2 to 4 months before any physical work starts, and we build that into the timeline upfront rather than surprising you with it later.
