If you’re a landed property owner or investor in Singapore looking to upgrade your home or increase its value, A&A (Additions & Alterations) works might be your ideal solution. Whether you’re modernising an older terrace house, adding a new room, or enhancing your property’s façade, A&A works allow you to do so — without the cost and hassle of a complete rebuild.
Here’s a 2025 guide to help you understand the A&A process, what’s involved, and why it’s a smart choice for homeowners like you.
What Are A&A Works – and Are They Right for You?
A&A works refer to improvements made to an existing building’s internal layout or external appearance — without drastically altering the structural framework. These upgrades can significantly improve comfort, functionality, and resale value.
Common A&A works include:
- Changing or upgrading your roof
- Adding or removing non-structural walls
- Building a new bathroom or room
- Modernising the interior layout
- Adding a skylight or extended patio
If your property feels outdated, too small, or doesn’t suit your lifestyle, A&A works can help you transform it without starting from scratch.
Why Landed Property Owners Choose A&A Works in Singapore
✅ Boost Property Value – Modern designs and functional layouts can raise resale prices and rental yield.
✅ Avoid Full Reconstruction – Keep existing foundations while upgrading important spaces.
✅ Tailored to Your Lifestyle – Redesign interiors, add bedrooms, or improve ventilation to meet your family’s needs.
✅ Faster and More Affordable – Shorter project timelines and fewer regulatory hurdles compared to rebuilding.
The A&A Process: What to Expect
1. Consultation & Site Inspection
A licensed professional (architect or A&A contractor) will inspect your home and recommend ideas based on your goals, site condition, and compliance rules.
2. Design & Planning
You’ll work closely with your architect or designer to finalise layout changes, materials, finishes, and budget. This is where your dream design comes to life — in line with URA & BCA guidelines.
3. Authority Submissions
Your professional team will handle submission to URA and BCA. This includes:
- Architectural drawings
- Compliance reports
- Written Permission (WP) applications
- Building Permit requests
4. Construction
Once approvals are secured, the construction begins. Most A&A projects take 4–12 months, depending on scope. A project manager will ensure everything runs smoothly, safely, and on schedule.
5. Completion & Handover
After construction, your builder will apply for TOP (Temporary Occupation Permit) or Certificate of Statutory Completion (CSC). Then — it’s all yours to enjoy.
Important Tips for Homeowners Starting A&A Works
- Hire Experienced A&A Specialists – Choose contractors familiar with landed property regulations.
- Plan for Temporary Relocation – For major works, you may need to move out during construction.
- Budget Smartly – Always include a 10–15% buffer for unexpected costs.
