Addition & Alteration
Adding a room, extending a side, enclosing a carport, converting an attic. The everyday A&A work — what most landed homeowners need when they outgrow the original layout. We handle URA and BCA submissions as part of the build.
The heavy side of landed construction. Structural alterations, additions, piling, and full rebuilds — handled by a licensed builder who tells you what your plot actually allows before the first dollar moves.
Every landed project is different, but most of our work falls into one of these five categories. If yours doesn't fit neatly, come talk to us anyway — we'll tell you if it's something we can do or if you need a different specialist.
Adding a room, extending a side, enclosing a carport, converting an attic. The everyday A&A work — what most landed homeowners need when they outgrow the original layout. We handle URA and BCA submissions as part of the build.
When A&A isn't enough, or when the existing structure isn't worth saving, we rebuild. Sometimes we keep the facade and rebuild everything behind it. Sometimes it's a clean demolition and a new two-storey home on the same plot.
Converting a single-storey to two-storey, adding a rooftop level, or extending upward. Every one of these starts with a structural check of what your existing foundation can actually carry — no quote without that assessment.
Bored piles, driven piles, micropiles for tight urban sites, underpinning of existing foundations. The invisible work that determines whether everything above lasts 50 years or starts cracking at year 10.
Removing load-bearing walls, inserting new beams and columns, transferring loads for open-plan layouts. This is where most renovation contractors stop and we start. The structural calculations are run before any hacking begins.
URA plot ratio, envelope controls, setbacks, GCB rules, conservation area rules — we check all of these against your actual property before quoting. If your idea won't get approved, you hear it from us first.

Any builder can send you a quote the same day. Very few can send you an honest one. Here's what we go through before we give you numbers — because an accurate quote takes a week, not an afternoon. If you want the plain-English version of what A&A works actually cover on a landed home first, we walk through it in the journal before you ever pick up the phone.
We collect a small deposit — typically 5 to 10 percent of project value — and bill the rest at milestones tied to actual job completion. Most of the project is only billed after the work has been done and verified.
If at any point during the build you're unhappy, you can stop the project and pay only for work that's been done. That's how much confidence we have in our team. And how much protection we want to give you.
This is materially different from how many builders bill — 30% or 40% upfront, then chasing the rest. We think that structure is the wrong way round. The client should carry the less risk, not more.
On a landed home, everything we build carries seven years from handover — structural works, plumbing, masonry, partitions, windows. Every item in your quotation has its warranty period written next to it, so you can see exactly what is covered and for how long before you sign anything.
There is one exception, and we would rather explain it than bury it: painting is quoted at five years. That is Nippon's own warranty on the product, and we will not put a longer number on something than its maker is willing to stand behind. If Nippon ever extends theirs to seven, ours goes to seven the same day. In practice most homes are due a repaint around that point anyway.
It is a workmanship warranty. In practice the thing owners worry about is leakage — and that is the thing it covers. Whether we did a window, masonry or structural job, if what we built leaks within those seven years, it is our problem to put right.
If something comes up, send us a photo or a video, or we arrange for someone to come and look at it. There is no inspection fee. If it turns out to be a small issue, we settle it for you at no charge.
The warranty follows the house, not the owner. If you sell within those seven years, whatever is left of it passes to the buyer. Worth having in writing when you come to sell.
What the warranty does not cover
Public liability insurance is in force for the whole of your project.
These terms apply to landed property. Work on non-landed property carries our standard 12-month warranty.
The short answer: if your project changes the structure of the building, or adds floor area, you need a BCA General Builder. If it's interior refinishing — carpentry, paint, new flooring, new bathrooms without moving plumbing walls — you need an HDB-licensed renovation contractor.
We're a BCA General Builder Class 2. That same General Builder licence is what lets us take on heavier commercial work too, like commercial warehouse construction. My sister's company, Larry Contractors, is HDB-licensed for renovation. Different licences, different scope, different specialisations.
When a client calls us and the project is really renovation in disguise, we refer them to Larry. When a client calls Larry and the project is really structural, they refer us. Keeps the work with whoever's actually licensed for it.
Send us the basics on WhatsApp. We'll come out for a site visit before any quotation.
